Write an equation in slope-intercept form for the line described.x-intercept (-7,0), y-intercept (0,1)
Answers
SOLUTION
The points are
\((-7,0)\text{ and (0,1)}\)The equation is writing using the formula below
\(\frac{y-y_1}{x-x_1}=\frac{y_2-y_1}{x_{2-}x_1}_{}\)where
\(x_2=0,x_1=-7,y_2=1,y_1=0\)Then, we substitute the parameters into the formula above
\(\begin{gathered} \frac{y-y_1}{x-x_1}=\frac{y_2-y_1}{x_{2-}x_1}_{} \\ \frac{y-1}{x-(-7)}=\frac{1-0}{0-(-7)} \end{gathered}\)Simplifying further, we have
\(\begin{gathered} \frac{y-1}{x+7}=\frac{1}{7} \\ 7(y-1)=x+7 \\ 7y-7=x+7 \\ 7y-x-14=0 \\ 7y=x+14 \end{gathered}\)Then in the slope-intercept form, we have the equation as
\(y=\frac{1}{7}x+2\)
Therefore the equation of the line in the slope-intercept form is
y=(1/7)x +2

Step-by-step explanation:
After training Naruto went to a ramen shop for dinner. Since Naruto eats ramen for lunch and dinner daily, the shopkeeper gives him a 33.33% discount. If ramen costs 45 cents, how much does Naruto spend in 15 days?
Points given: 20
Answers
To calculate how much Naruto spends on ramen in 15 days, we need to determine the total cost of ramen per day and then multiply it by 15.
Since Naruto receives a 33.33% discount, he pays 100% - 33.33% = 66.67% of the original price.
66.67% of 45 cents is (66.67/100) * 45 = 30 cents.
So, Naruto spends 30 cents on ramen per day.
To find out how much he spends in 15 days, we multiply the daily cost by the number of days:
30 cents * 15 = 450 cents.
Therefore, Naruto spends 450 cents, which is equivalent to $4.50, on ramen in 15 days.
if a small cup is 10 oz and cost 2.69 what is the cost per ounces
Answers
Answer:
The cost per ounce of the small cup is $0.269
Step-by-step explanation:
To find the cost per ounce, we can divide the cost of the cup by the number of ounces it holds.
Cost per ounce = Cost of the cup ÷ Number of ounces in the cup
Cost of the cup = $2.69
Number of ounces in the cup = 10 oz
So,
Cost per ounce = $2.69 ÷ 10 oz
Cost per ounce = $0.269 per oz (rounded to the nearest thousandth)
Therefore, the cost per ounce of the small cup is $0.269.

Answers
Answer: let me explain!
Step-by-step explanation: So this might seem really confusing at first, but it’s actually suuuuuuper easy :P
So, if you think about it, every five seconds the amount of peanuts…well I don’t know how to explain it but let me show you this with numbers.
(4x2)x2x2x2 and so on. The number multiplies by two every five seconds from there. So figure out how many groups of five second there are in 100 seconds by dividing!
It’s 20!
So since 5 happens 20 times, and every time 5 happens, 2 happens, 2 also happens 20 times! (If that makes any sense)
So that answer would be 8x*twenty twos*
Which is…*drumroll please*
8,388,608
I even double checked!
And for the briefcase skeleton thing
She needs to try it 25 times because there are 5 books and each book can be switched with the other 4 times if the first one doesn’t work, therefore you need to multiply and the equation would be 5^2, or in other words, 25.
Don’t forget ur units!

Lokesh had no money and then got his weekly allowance. He spent half of his weekly allowance at the baseball game. The next day he mowed the lawn and earned $9.00 more. He didn’t spend or earn any more money for the rest of the week. What is his weekly allowance if he ended up with $13.00 at the end of the week?
Answers
To solve this problem, we can use algebraic equations. Let's start by defining some variables:
Let \(x\) be Lokesh's weekly allowance.He spent half of his weekly allowance at the baseball game, so he spent \(\frac{x}{2}\) dollars.The next day he mowed the lawn and earned $9.00 more, so he had \(\frac{x}{2} + 9.00\) left for the rest of the week.He didn’t spend or earn any more money for the rest of the week, so he ended up with $13.00 at the end of the week.Putting all of this together, we can write the following equation:
\(\boxed{\frac{x}{2} + 9.00 = 13}\)
Subtracting both sides by nine, we get:
\(\boxed{\frac{x}{2} = 4}\)
Multiplying both sides by 2, we get:
\(\boxed{x = 8}\)
Therefore, Lokesh's weekly allowance is $8.00
----------------------------------------------------------------------------------------------------------
Checking the answerMethod 1:Lokesh spent half of $8 in the baseball game:
$8 ÷ 2 = $4
The next day, he earned $9 by mowing the lawn:
$4 + $9 = $13
He didn't spend any more money by the rest of the day, so he had $13 left.
He would have $13 left if $8 is his weekly allowance, which is what we got.
Method 2We can subsitute \(x\) with 8:
\(\frac{8}{2} + 9.00 = 13\)\(4 + 9 = 13\)\(13 = 13\)Since the left-hand side is equal to the right-hand side, the answer is correct.

Answers
Each function on the left should be matched to all points on the right that would be located on the graph of the function as follows;
f(x) = 2x + 2 ⇒ (0, 2).
f(x) = 2x² - 2 ⇒ (-1, 0).
\(f(x) = 2\sqrt{x+1}\) ⇒ (0, 2).
What is a function?In Mathematics and Geometry, a function is a mathematical equation which defines and represents the relationship that exists between two or more variables such as an ordered pair in tables or relations.
Next, we would determine the point or ordered pair that represent a solution on the graph of each of the function as follows;
For the ordered pair (0, 2), we have:
f(x) = 2x + 2
2 = 2(0) + 2
2 = 2 (True).
For the ordered pair (-1, 0), we have:
f(x) = 2x² - 2
0 = 2(-1)² - 2
0 = 2 - 2
0 = 0 (True).
For the ordered pair (0, 2), we have:
\(f(x) = 2\sqrt{x+1}\\\\2= 2\sqrt{0+1}\\\\2 = 2\sqrt{1}\)
2 = 2 (True).

Circle X is shown in the diagram.
Circle X is shown. 2 chords intersect at a point to form arcs a and b. Arc a is intercepted by angle 1. Arc b is intercepted by angle 2. Arcs d and c are the other 2 arcs.
Which equation can be used to solve for m∠1?
m∠1 = One-half(a – b)
m∠1 = One-half(a + b)
m∠1 = One-half(c – d)
m∠1 = One-half(c + d)
Answers
Answer:
The equation that can be used to solve for m∠1 is:
m∠1 = One-half(a – b)
This is because angle 1 intercepts arc a, which has a measure of a. By the same token, angle 2 intercepts arc b, which has a measure of b. The sum of the measures of angles 1 and 2 is equal to the measure of the angle formed by the two intersecting chords, which is one-half the sum of the measures of arcs a and b. Therefore, we have:
m∠1 + m∠2 = One-half(a + b)
Since m∠2 is not given, we cannot solve for m∠1 using this equation. However, we can use the fact that the sum of the measures of the angles in a triangle is 180 degrees to get:
m∠1 + m∠2 + m∠3 = 180
where m∠3 is the measure of the angle formed by the two chords outside the circle. Since this angle is supplementary to angle 1, we have:
m∠1 + m∠3 = 180
Substituting the equation for the sum of the measures of angles 1 and 2, we get:
m∠1 + One-half(a + b) = 180
Solving for m∠1, we get:
m∠1 = 180 - One-half(a + b) = One-half(360 - a - b) = One-half(a - b)

Let F, G, R denote the set of students studying French, German and Russian respectively. Then find the number of students studying at least one of the three languages i.e, n(FUGUR)
Answers
The value of n (FUGUR) will be;
⇒ n (FUGUR) = 112
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The data of mathematics students is,
60 study French, 30 study French and German
55 study German, 25 study French and Russian
75 study Russian, 35 study German and Russian
12 students study all the three languages.
Now,
Let F, G, R denote the set of students studying French, German and Russian respectively.
And, The data of mathematics students is,
n (F) = 60, n (F ∩ G) = 30
n (G) = 55, n (F ∩ R) = 25
n (R) = 75 , n (G ∩ R) = 35
n (F ∩ G ∩ R) = 12
Since, We know that;
⇒ n (FUGUR) = n (F) + n (G) + n (R) - n (F ∩ G) - n (F ∩ R) - n (G ∩ R)
+ n (F ∩ G ∩ R)
Substitute all the values, we get;
⇒ n (FUGUR) = n (F) + n (G) + n (R) - n (F ∩ G) - n (F ∩ R) - n (G ∩ R)
+ n (F ∩ G ∩ R)
⇒ n (FUGUR) = 60 + 55 + 75 - 30 - 25 - 35 + 12
⇒ n (FUGUR) = 112
Thus, The value of n (FUGUR) will be;
⇒ n (FUGUR) = 112

Given a doubling time of 934 minutes, how long will it take a culture in the exponential growth phase to grow from 15 cells per mL, to 86,059 cells per mL? Explain.
Answers
It will take approximately 7.12 days for a culture with a doubling time of 934 minutes to grow from 15 cells/mL to 86,059 cells/mL. This is calculated using the exponential growth equation and logarithms.
If the doubling time is 934 minutes, it means that the number of cells in the culture doubles every 934 minutes. Let t be the time in minutes required to grow from 15 cells/mL to 86,059 cells/mL. We can set up the following equation:
86,059/15 = 2^(t/934)
Taking the logarithm of both sides, we get:
log(86,059/15) = (t/934) log(2)
Solving for t, we get:
t = (log(86,059/15)/log(2)) * 934 ≈ 10,288 minutes ≈ 7.12 days
Therefore, it will take approximately 7.12 days for the culture to grow from 15 cells/mL to 86,059 cells/mL under the given conditions.
