Answer:

7. 4

8. 7

Step-by-step explanation:

7. $\frac{1}{2} = \frac{x}{8}$

Cross multiply

$1*8 = x*2$

$8 = 2x$

$\frac{8}{2} = \frac{2x}{2}$ (division property of equality)

$4 = x$

$x = 4$

8. $\frac{3}{x - 3} = \frac{6}{8}$

Cross multiply

$3*8 = 6(x - 3)$

$24 = 6x - 18$

$24 + 18 = 6x$ (addition property of equality)

$42 = 6x$

Divide both sides by 6

$7 = x$

$x = 7$

Answer:

Vertex (-2.5,-300)

Step-by-step explanation:

We are given with h(t)=-16 t^2 +80 t. We are asked to find the vertex.

X-coordinate of vertex = $\frac{-b}{2a}$

Where 'a' is coefficient of $t^{2}$ term

'b' is coefficient of 't' term.

From given function, a= -16

b=80

So,

x-coordinate of vertex = $\frac{-80}{2(-16)}$

=-2.5

y-coordinate of vertex = $-16(-2.5)^{2} +80(-2.5)$

Simplify it,

=-100 -200

= -300

So, vertex is at (-2.5, -300).
