Answer:
y=-5/4x+5
Step-by-step explanation:
Slope: m= -5/4
The slope is -5/4 because it goes down 5 points and over 4 points from the first dot to the second one. With slope, you count how many numbers are in between the two dots from up/down and left/right. Put the rise (up/down) over the run (left/right). The 5/4 is negative because the line goes from top left to bottom right. It would be positive if it was the opposite.
Y intercept: 5
This is just the point that your line touches the Y line (vertical one)
Equation: y= -5/4x+5
Slope intercept form is this: y=mx+b
The m is your slope. The b is your y intercept.

The table of values below represent an exponential function. Find the constant ratio of successive y-values. x y -2 5 -1 7.5 0 11.25 1 16.875 2 25.3125 a. 5 c. 1.5 b. 1.33 d. 0.5
Answer: 1.5
Step-by-step explanation:
To find the constant ratio of successive y-values, we need to divide each y-value by the previous one.
For example, to find the ratio between the second and first y-values:
7.5 ÷ 5 = 1.5
Similarly, we can find the other ratios:
11.25 ÷ 7.5 = 1.5
16.875 ÷ 11.25 = 1.5
25.3125 ÷ 16.875 = 1.5
Since all the ratios are the same, we can conclude that the constant ratio of successive y-values is 1.5.
Therefore, the answer is c. 1.5.
solve each system by elimination. -2x + 8y = -30 9x - 16y = 15
Answer: −0.147540984 or 1.911885246
Answer:
(-9, -6)
Step-by-step explanation:
-2x+8y=-30
9x-16y=15
Start by multiplying the first equation by 2:
-4x+16y=-60
Now, add the two equations to eliminate y:
9x-4x=15-60
5x=-45
Divide both sides by 5
x=-9
Plug -9 in for x to solve for y:
-2(-9)+8y=-30
18+8y=-30
Subtract 18 from both sides
8y=-48
Divide both sides by 8
y=-6
(x,y)=(-9,-6)

Consider function f, where B is a real number.

Complete the statement describing the transformations to function f as the value of B is changed.
As the value of B increases, the period of the function
When the value of B is negative, the graph of the function
shy
and the frequency of the function
If the value of B increases, the period of the function decreases, and the frequency of the function increases. When the value of B is negative, the graph of the function reflects over the y-axis.
How to estimate the graph and the frequency of the function?Let the tangent function be f(z) = tan (Bz)
The period exists \($P=\frac{\pi}{|B|}$\)
The frequency exists \($F=\frac{1}{P}=\frac{|B|}{\pi}$\).
The period exists inversely proportional to B, therefore, as B increases, the period decreases.
Frequency exists inversely proportional to the period, therefore, as the period decreases, the frequency increases.
When B is negative, we get f(z) = tan -Bz = f(-z), therefore, the function exists reflected over the y-axis, as the graph at the end of the answer shows, with f(z) exists red(B positive) and f(-z) exists blue(B negative).
As the value of B increases, the period of the function decreases, and the frequency of the function increases. When the value of B exists negative, the graph of the function reflects over the y-axis.

How much water should be added to 22 ml of 12% alcohol solution to reduce the concentration to 11%
The amount of water that is needed to be added to the 12% concentration solution to make it 11% concentrated is 2 ml.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Given that the alcohol solution of 22 ml has a 12% of concentration. Therefore, the amount of alcohol in the solution is,
12% of 22ml = 2.64ml
Since the amount of alcohol should be the same while the concentration should be diluted, therefore, the amount of alcohol in the final solution can be written as,
\(11\%\ of\ x = 2.64{\rm\ ml}\\\\\dfrac{11}{100} \times x = 2.64\\\\x = 24\rm\ ml\)
As the total solution with 12% concentration was 22 ml, while the total solution with 11% concentration was 24 ml.
Hence, the amount of water that is needed to be added to the 12% concentration solution to make it 11% concentrated is 2 ml.

when its comes to interest,most CDs will allow which of the following options?
a. Unlimited withdraws of interest
b. Periodic interest payout
c. loans against principal
d. Withdrawal of principal
When it comes to interest, most Certificates of Deposit (CDs) will allow periodic interest payouts. So, correct option is B.
A CD is a type of savings account that allows you to earn a fixed interest rate on your deposit for a specific period of time, called the term. Typically, the longer the term of the CD, the higher the interest rate offered.
However, during the term of the CD, the funds are locked in, meaning that you cannot withdraw the principal without incurring a penalty.
While some CDs may allow for unlimited withdrawals of interest, this is not common, and may still come with restrictions or penalties. Loans against principal are also not typically allowed with CDs, as the funds are meant to be held for a set term.
Therefore, the most common option available for CD holders is to receive periodic interest payouts, which can be monthly, quarterly, or annually, depending on the terms of the CD. This allows the CD holder to earn interest on their deposit while still receiving some income during the term of the CD.
So, correct option is B.

Brianna made 9 1/4 bags of popcorn for a movie night with some friends. Together they ate 4 bags of it. How much popcorn was left?
There were 5 1/4 bags of popcorn left after eating 4 bags.
To find out how much popcorn was left after eating 4 bags, we need to subtract the amount eaten from the total amount Brianna made.
Brianna made 9 1/4 bags of popcorn, which can be represented as a mixed number. To perform calculations, let's convert it to an improper fraction:
9 1/4 = (4 * 9 + 1) / 4 = 37/4
Now, let's subtract the 4 bags eaten from the total:
37/4 - 4
To subtract fractions, we need a common denominator. The common denominator of 4 and 1 is 4. Therefore, we can rewrite the expression as:
37/4 - 4/1
Now, let's find a common denominator and subtract the fractions:
37/4 - 16/4 = (37 - 16) / 4 = 21/4
The result is 21/4, which is an improper fraction. Let's convert it back to a mixed number:
21/4 = 5 1/4
Therefore, there were 5 1/4 bags of popcorn left after eating 4 bags.
