If we are to express the linear equation in slope-intercept form wherein the slope is the cost per download and y is the total cost. The answer should be,

Website 1: slope = 1.5 and y-intercept = 30

The equation that would represent the given is,

                  y = 1.5x + 30

Website 2: If we consider that there is no additional cost for this except for the cost per downloaded music then, the equation would be,

                y = 2x

Can someone please help me with this math question .
Alona [7]

No, Yes, No, Yes

using the laws of exponents

(1)

(4^{3})³ = 4^{9}

4³ × 4³ = 4^{6}

4^{9} ≠ 4^{6} → No

(2)

(3^{4})^4 = 3^{16}

3^{8} × 3^{8} = 3^{16} → Yes

(3)

18^{8} = (6 × 3 )^8 = 6^{8} × 3^{8} ≠ 6^{4} × 3^{4} → No

(4)

20^{3} = (4 × 5 )³ = 4³ × 5³ → Yes
