Get all your variables on same side and solve x=-2
the first one is 9
I don't even understand the question
Explanation:
60x5 = 300
8x20 = 160
25x9 = 225
33x10 = 330
300+160+225+330= 1015
so....
the answer is B. 1015
Answer:
D
Step-by-step explanation:
Answer:
The vertex and the axis of symmetry in the attached figure
Step-by-step explanation:
we know that
The equation of a vertical parabola written in vertex form is equal to

where
a is the leading coefficient
(h,k) is the vertex of the parabola
and the equation of the axis of symmetry is equal to the x-coordinate of the vertex

In this problem
we have

This is a vertical parabola written in vertex form open upward
The vertex is a minimum
where
the vertex is the point (5,-7)
the x-coordinate of the vertex is 5
so
the equation of the axis of symmetry is equal to

The graph in the attached figure
