Answer:
c) y = - 2 x +3
d) y = 1/2 x + 1
Step-by-step explanation:
For c) Look for the exression that contains "3" as the y-intercept (the "b" in the form y = m x + b)
The only equation is y = - 2 x +3
For d) try in all equations if replacing x with 2, gives you an answer "2" for y as well.
The only equation that does such is y = 1/2 x + 1
Answer:
A: 1313.81
Step-by-step explanation:
Hopefully this helps!
-14 3/5 -20= -34.6
you have to get the S alone so you move the 20 to the other side of the =. so S= -34.6
We have two similar triangles, the one as a whole and the one inside of it. To calculate the height of the flagpole we can set up a proportion. First calculate the length of the base of the smaller triangle.
16.60 - 12.45 = 4.15m
The height is 1.65m, set up a proportion:

Cross multiply:

Divide 4.15 to both sides:

So the height of the flagpole is 6.6 meters tall.
Answer:
11
Step-by-step explanation:
f(x) = x^2 - 3x + 1
f(-2) = (-2)^(2)-3(-2)+1
f(-2) = 4 + 6 + 1
f(-2) = 11
Just substiute -2 for x and sove.
