Answer:

a = 0

Step-by-step explanation:

4(a-2) = 2(a-4) + 2a

4a - 8 = 2a - 8 + 2a

4a - 2a - 2a = -8 + 8

0 = 0

Answer:

A 32.1

Step-by-step explanation:

Given two points $(x_{1} ,y_{1} ) and (x_{2} ,y_{2})$ )

distance between to points = d = $\sqrt{(x_{2} - x_{1} )^{2} + (y_{2} - y_{1} )^{2} }$

Now B is (-4,5) and A is (2,0)

So AB = $\sqrt{(-4-2)^{2} +(5-0)^{2} } = \sqrt{36 + 25} = \sqrt{61\\} = 7.810...$

C is (4,10)

So BC = $\sqrt{(-4-4)^{2} +(5-10)^{2} } =\sqrt{64 + 25) } =\sqrt{89} =9.433...$

D is (8,7)

So CD = $\sqrt{(4-8)^{2} +(10-7)^{2} } =\sqrt{16 + 9} = \sqrt{25} = 5$

E is (4,5)

So DE = $\sqrt{(8-4)^{2} + (7-5)^{2} } = \sqrt{16 + 4} = \sqrt{20} = 4.472...$

and AE = $\sqrt{(4-2)^2 + (5-0)^2} =\sqrt{4+25} = \sqrt{29} = 5.385...$

Perimeter = 7.810 + 9.433 + 5 + 4.472 + 5.385 = 32.1

Answer:

(b) g, h, f

Step-by-step explanation:

The larger the magnitude of the vertical scale factor, the quicker the graph takes on higher values. That makes its appearance narrower.

Here, you want to list the functions in decreasing order of vertical scale factor:

g(x) . . . scale factor 4

h(x) . . . scale factor 2

f(x) . . . scale factor 1/3
