Answer:

Step-by-step explanation:
Your equation is in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept. Your line has a slope of 7. In order to find the line perpendicular to this line, we have to take the opposite reciprocal of the slope. The perpendicular slope to m = 7 is m = -1/7. Now we go through x = -5 and y = 6 to find the new equation.
6 = -1/7(-5) + b gives us
6 = 5/7 + b and
b = 37/7
Therefore, the equation of the line perpendicular to your original line is

Answer: I can answer 20
I think....the answer... Is......2 1/2
Step-by-step explanation:
Given
(2x + 3 )² - (2x + 3) (x - 5)
= 4x² + 6x + 9 - ( 2x (x - 5) + 3(x - 5 ))
= 4x² + 6x + 9 - ( 2x² - 10x + 3x - 15 )
= 4x² + 6x + 9 - 2x² + 10x - 3x + 15
= 2x² + 13x + 24
Hope it will help :)
It can be represented by a simple equation. 600 - 45 + 10
