1) First one is a line f(x)=2x+1. It has y-int. (0,1), and second point, for example, (1,3)
2 points for line (0,1) and (1,3)2) Second one is a parabola g(x)=x²+2x-8.
In the vertex form it looks like
g(x) =x²+2x+1-1-8=(x+1)²-9
g(x)=(x+1)²-9 - parabola in the vertex form. Vertex is (-1,-9)Another point of the parabola can be found from the equation g(x)=x²+2x-8.
It is y-int. x=0, g(0)=-8, so
point on the parabola is (0,-8)For parabola Vertex (-1,-9) and point (0,-8)3) Solutions are (-3,-5) and (3,7).
Answer:
basically u dont do it because it wount mean anything in da future.

The 3rd one I think is the right one
Answer:
m ≤ 150
Step-by-step explanation:
Let the variable "m" = the McDonald family.
Note that "spends no more than" means that they can spend less than or equal to the number provided, but not greater than. The sign for "less than or equal to" is ≤. 150 is the limit.
Set the inequality:
<em>m</em> ≤ 150 is your answer.
