Step-by-step explanation:
the table shows how much money Eddie has after buying some games and
represents a linear function.
The y intercept is (0, 142) and it represents how much Eddie has before buying any game.
The formula of a linear function is:
y = mx + b;
where y,x are variables, m is the slope of the line and b is the y intercept (value of y when x is 0)
Let x represent the number of games and y represent the amount of money.
From the table, the y intercept is the value of y when x is 0. It is given by:
(0, 142).
Hence the y intercept is (0, 142) and it represents how much Eddie has before buying any game.

The concept of best-, worst-, and average-case analyses extends beyond algorithms to other counting problems in mathematics. Recall that the height of a binary tree is the number of edges in the longest path from the root to a leaf. Find the best-case height of a binary tree with seven nodes.
the height of a binary tree is the number of edges in the longest path from the root to a leaf.The best-case height of a binary tree with seven nodes is 3.
A binary tree is a type of tree structure consisting of nodes that are connected by edges. The number of edges in the longest path from a binary tree's root to a leaf determines the tree's height.In the best-case scenario, the binary tree is perfectly balanced and each node has exactly two children. With seven nodes, the best-case height is three because each node has two children and three edges connect the root node to the leaves. This means that the longest path from the root to a leaf is three edges, resulting in a height of three.

-319.45 = m
Solve for m
Answer:
STo solve for m in the equation -319.45 = m, we can isolate the variable m by adding 319.45 to both sides of the equation:
-319.45 + 319.45 = m + 319.45
This simplifies to:
0 = m + 319.45
Finally, we can subtract 319.45 from both sides to solve for m:
0 - 319.45 = m + 319.45 - 319.45
-319.45 = m
Therefore, the value of m is -319.45.tep-by-step explanation:

Composite Functions for : f [ g (x) ] = 3 g(x) + 7 will be f [ g(x) ] = 3 ( 5x - 5) + 7 = 15x - 8
Common functions typically have a subset of the real numbers as their domain. Any integer from the domain may be used to replace a variable.
The domain of a composite function is determined by another function, not by a collection of numbers. We refer to it as "a result of another function. Example:
If: . f (x) = 3x + 7 . f [g(x)] must be found and simplified. g(x) = 5x - 5. Due to the fact that the domain of this function is a function of another function, f (x) is a simple function or just a function.
Let's make the example I gave previously simpler.
G (x) signifies in f "Replace x with g (x) in the function f (x). The Composite function f [g (x)]

What is inequality?In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign (≠)" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than.
The given inequality is:

Which equations are true for x = –2 and x = 2? Select two options x2 – 4 = 0 x2 = –4 3x2 + 12 = 0 4x2 = 16 2(x – 2)2 = 0
The equations that are true for x = -2 and x = 2 are x² + 4 = 0 and 4x² = 16. So, the correct option is A) and D).
To determine which equations are true for x = -2 and x = 2, we simply substitute these values into each equation and check if the equation is true or not. Here are the results
x² - 4 = 0
Substituting x = -2 gives (-2)² - 4 = 0, which is true. Substituting x = 2 gives 2² - 4 = 0, which is also true. Therefore, this equation is true for both x = -2 and x = 2.
x² = -4
Substituting x = -2 gives (-2)² = -4, which is not true. Substituting x = 2 gives 2² = -4, which is also not true. Therefore, this equation is not true for either x = -2 or x = 2.
3x² + 12 = 0
Substituting x = -2 gives 3(-2)² + 12 = 0, which is true. Substituting x = 2 gives 3(2)² + 12 = 24, which is not equal to zero. Therefore, this equation is true for x = -2 but not for x = 2.
4x² = 16
Substituting x = -2 gives 4(-2)² = 16, which is true. Substituting x = 2 gives 4(2)² = 16, which is also true. Therefore, this equation is true for both x = -2 and x = 2.
2(x - 2)² = 0
Substituting x = -2 gives 2(-2 - 2)² = 0, which is true. Substituting x = 2 gives 2(2 - 2)² = 0, which is also true. Therefore, this equation is true for both x = -2 and x = 2.
Therefore, the two equations that are true for both x = -2 and x = 2 are x² - 4 = 0 and 4x² = 16. So, the correct answer is A) and D).

5 6/30+1 3/4=
Need step by step answers
Answer:
Step by step answers are key,... and they're below,... ;->
Step-by-step explanation:
This is your equation:
\(5 \frac{6}{30} + 1\frac{3}{4}\)
Make both fractions improper fractions (this makes them easier to work with) All you did to convert your two mixed number into improper fractions is:
Multiply the denominator (the bottom number in a fraction in this case 30) by the number not in the fraction (5), 30x5=150 and then add the product (150) to the numerator (the top number in a fraction (which in this case is 6))
\(5\frac{6}{30} = \frac{156}{30}\)
Do the same to the other mixed number (turning it into a improper fraction), Multiply the 4x1=4, add the product to the numerator 4+3=7 and then you have your second improper fraction
\(1\frac{3}{4} = \frac{7}{4}\)
Your new equation:
\(\frac{156}{30} +\frac{7}{4}\)
Now you need to get both denominators the same so you can add the together,... the easiest way to do this is to multiply the two denominators together,... 30x4=120
\(\frac{x}{120} + \frac{x}{120}\)
But how do we know what the numerator are to be? What you have to do is the following,... you had to multiply 30 by 4 to get to 120, so you have to multiply the 156 by 4 to make an equivilant fraction,... 156x4=624
\(5\frac{6}{30} = \frac{156}{30} = \frac{624}{120}\)
Like wise you had to multiply 4 by 30 to get to 120 so you have to multiply the numerator by 30 to make the fraction hold the same value,... 7x30=210
\(1\frac{3}{4} = \frac{7}{4} =\frac{210}{120}\)
Now all that is left is to add:
\(\frac{624}{120} +\frac{210}{120} =\frac{834}{120}\)
The answer is 835/120 simplify is or 6 19/20 or 6.95

Below is a graph of the relationship between the cost and distance driven. Find the slope of the line.
Answer: d. 25
Step-by-step explanation: This is correct because the graph starts at 75 and then jumps to 100. 75 + 25 is 100. This then goes from 100 to 125. Again, 100 + 25 is 125. Finally, it goes from 125 to 150. 125 + 25 equals 150. The final answer is 25 because each time the line increases, it increases by 25.

A radioactive substance decays exponentially. A scientist begins with 110 milligrams of a radioactive substance. After 15 hours, 55 mg of the substance remains.
How many milligrams will remain after 25 hours?
mg
Give your answer accurate to at least one decimal place.
We can use the formula for exponential decay:
N(t) = N0 * e^(-kt)
where:
N(t) = amount remaining after time t
N0 = initial amount
k = decay constant
We can solve for k using the given information:
55 = 110 * e^(-k * 15)
e^(-k * 15) = 0.5
-k * 15 = ln(0.5)
k = -ln(0.5) / 15
k ≈ 0.0462
Now we can use this value of k to find N(25):
N(25) = 110 * e^(-0.0462 * 25)
N(25) ≈ 39.6 mg
Therefore, approximately 39.6 milligrams will remain after 25 hours.

In a class of 80 Students, 30 offered mathematics, 20 offered Accountancy and 40 offered Economics. Those who offered both mathematics and accountancy are more than those who offered both Accountancy and Economics by 2. No student offered all the subjects and none offered both mathematics and Economics. Find the number of students who offered Accountancy only?
The number of students who offered Accountancy only is 10.
Let's represent the number of students who offered Mathematics as M, the number of students who offered Accountancy as A, and the number of students who offered Economics as E.
From the given information:
M = 30 (Number of students who offered Mathematics)
A = 20 (Number of students who offered Accountancy)
E = 40 (Number of students who offered Economics)
We are also given the following conditions:
M ∩ A > A ∩ E by 2
M ∩ E = 0
We know that the total number of students is 80, so:
M + A + E = 80
Now, let's solve for the number of students who offered Accountancy only.
We can start by substituting the given values into the equation:
30 + 20 + 40 = 80
Now, we need to find the value of A ∩ E (Number of students who offered both Accountancy and Economics).
Since none offered both Mathematics and Economics, we can subtract M from A:
A - M = A ∩ E
20 - 30 = A ∩ E
-10 = A ∩ E
Since A ∩ E cannot be a negative number, we know that A ∩ E = 0.
Now, let's use the first condition: M ∩ A > A ∩ E by 2.
Substituting the values, we have:
M ∩ A - A ∩ E = 2
M ∩ A - 0 = 2
M ∩ A = 2
Now, we can substitute the values of M ∩ A and M into the equation M + A + E = 80:
30 + A + 40 = 80
A + 70 = 80
A = 10
