Answer:

y=1/8x+1.25

Step-by-step explanation:

Since it's perpendicular change the slope to the opposite

You have the slope so plug it into the equation y-y1=m(x-x1)

y-(1)=(1/8)(x--2)

Ray Of Light [21]
F(g(2))

g(x) = x^2 - 6x - 7
g(2) = 2^2 - 6(2) - 7
g(2) = 4 - 12 - 7
g(2) = -15

f(x) = x + 8
f(g(2) = f(-15) = -15 + 8 = -7 <==

ur answer is -7

Help!!!<br> Find the zeros of the quadratic equation by factoring.<br><br> x^2+4x-5=0
weqwewe [10]

Answer:

x = -5, 1

Step-by-step explanation:

To factor an equation, break the polynomial into two binomials which multiply to make it. Find two numbers that multiply to C and add to B from ax^2 + bx + c.

-1 and 5 multiply to -5 and add to 4.

x^2+4x-5 = (x+5)(x-1)

The zeros are the factors set equal to 0 and solved.

(x+5) = 0

x=-5

(x-1) = 0

x=1
