Y=x2−6x+10
y=4−x

how do i substitute?

(2,2) and (3,1)

Step-by-step explanation:

Since we're given the value of y in the second equation, we can replace the y on the left side of the first equation with 4-x, giving us

We can factor the expression on the right to get us

Solving and gets us the solutions , which we can plug into the second equation to get us

So, our solution set is the pair of points (2,2) and (3,1)

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm

i think is g(1)=-1.

hope that i can
