Answer:
(17,3)
Step-by-step explanation:
Equation 1.
x=5y+2
Equation 2.
x-4y=5
To solve with substitution, it looks like the x-variable in the first equation is already isolated. So, plug the first equation into the x-variable in the second equation.
x-4y=5
(5y+2)-4y=5
y+2=5
y=3
Now that we found y, plug y into one of the equations to solve for x.
x=5y+2
x=5(3)+2
x=15+2
x=17

Answer:
x=0
Step-by-step explanation:
4/8=1/2, so:
x+1/2=1/2
x=0
Gertie 3/4 mile.
Sarah 2/4 mile.
Gertie ran farther by: 3/4 - 2/4 = (3 -2)/4 = 1/4
Gertie ran farther by 1/4 mile.

Answer:
f(x)= (x+8)^2 + 200
Step-by-step explanation:
-b/2a gives you the x coordinate of the vertex and then plug it in for x to get the y coordinate. Put it in the formula (f()x= (x-h)^2 +k).
H is the x coordinate and K is the y coordinate
