Answer:
Step-by-step explanation:
y = x + 9 is the given equation of a line. The coefficient of 'x' is 1. Therefore the slope of this line is 1.
The slope of any line perpendicular to this y = x + 9 is the negative reciprocal of 1, which is -1.
Using the point-slope formula for the equation of a straight line, y - k = m(x - h), we identify h and k as -2 and -2 respectively, from the given point (-2, -2).
Then, y - k = m(x - h) becomes y + 2 = -1(x + 2) (in point-slope format)
Answer:
77.08%
Step-by-step explanation:
850 - 480 = 370
(370 / 480 ) × 100 = 77.08333333%
The inverse of the function f(x)= 2x/7 + 4 is y = 7x/2 - 14.
<h3>What is the inverse of the function?</h3>
Given the function; f(x)= 2x/7 + 4
First. we write the function as an equation then interchange the variables.
y = 2x/7 + 4
x = 2y/7 + 4
We solve for y.
2y/7 = x - 4
2y = 7x - 28
y = 7x/2 - 28/2
y = 7x/2 - 14
Therefore, the inverse of the function f(x)= 2x/7 + 4 is y = 7x/2 - 14.

Answer:
Those ratios are not equivalent
Step-by-step explanation:
3:4 is not the same as 4:3 because 3:4 means 3 out of 4 but 4:3 means 4 out of 3 which means it is more than one while 3:4 is less than one
