Wherever you see an x, replace it with -5
So f(-5) = -(-5^2) -7(-5) -5
= -(25) + 35 - 5
= -25+30
= 5

Write a parallel and perpendicular equation that passes through the point (6,-2)?

Reptile [31]

Answer:

y=x-8 and y=-x+4

Step-by-step explanation:

The slopes of the lines can be anything, as long as they are the opposite reciprocals of each other. Then you can plug in the point for x and y to solve for b in both lines (for y=mx+b where m is the slope)

What is an equation of the line that passes through the point (-5 7) and is parallel to the line x-5y=15

mafiozo [28]

Answer:

Step-by-step explanation:

Parallel lines have same slope.

y = mx + b

Slope = m & y-intercept = b

x - 5y = 15

-5y = -x + 15

y = $\frac{-1}{-5}x + \frac{15}{-5}\\\\$

$y = \frac{1}{5}x - 3$

so, slope = 1/5 ; (-5 , 7)

y -y1 = m(x -x1)

$y - 7 = \frac{1}{5}(x- [-5])\\\\y - 7 =\frac{1}{5}(x + 5)\\\\y - 7 = \frac{1}{5}x+5*\frac{1}{5}\\\\y - 7 =\frac{1}{5}x+1\\\\y =\frac{1}{5}x+1+7\\\\y=\frac{1}{5}x + 8$
