Answer:
45
Step-by-step explanation:
x - 7 = 38
add 7 to both sides to get the variable by itself
x = 45
Answer:
5 blocks
Step-by-step explanation:
Since the triangle is right use Pythagoras' identity to solve for AC
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
AC² = AB² + BC² ← substitute values
AC² = 3² + 4² = 9 + 16 = 25 ( take the square root of both sides )
AC =
= 5
Based on the calculation below, Cheryl's net pay is $1,667.50.
<h3>How do we calculate net pay?</h3>
Cheryl's net pay can be calculated using the following formula:
Net pay = Gross pay * (100% - 30% - 12%) ......................... (1)
Substituting for gross pay in equation (1), we have:
Net pay = $2,875 * (100% - 30% - 12%)
Net pay = $2,875 * 58%
Net pay = $1,667.50

Answer: Slope is -1
Using the slope formula, we get
m = (y2 - y1)/(x2 - x1)
m = (0 - 4)/(2 - (-2))
m = (0 - 4)/(2 + 2)
m = -4/4
m = -1
What's going on here is that we subtract the y values 0 and 4 to get -4. This means that we dropped 4 units vertically to go from A to B. This is the rise. So rise = -4
The run is 4 because we moved 4 units to the right to go from A to B. This is found algebraically when we subtracted the x coordinates, so 2 - (-2) = 2 + 2 = 4.
Slope = rise/run = -4/4 = -1
You have the correct answer, assuming you wrote -1. I think your teacher just marked it wrong because you forgot to show steps.
