Answer:

1.True 2.False 3.True 4.False

Step-by-step explanation:

1. 2^4 x 2^3 = 2^(4+3) = 2^7 --> True

2. 1^0 x 0^1 = 1 x 0 = 0 --> False

3. 3^4 = 81

4^3 = 64

81 > 64

3^4 > 4^3 --> True

4. 4^0 + 5^0 + 6^0 = 1 +1 +1 = 3

(4+5+6)^0 = 15^0 = 1 --> False

A) 0.15 times $2,570 = $412.50

B) $122.85 times 2( 12 ) = $2,948.40

C) $2,570

D) All together it's  $2,948.40 + $2,570 = $5,518.40

For D I didn't add the down payment because it's not an additional charge.

I only did the first one because I don't know if you want me to finish the rest.

Hope I helped :)

Write a linear function f with the given values. f(0) = -2,f(4) = -3
Thepotemich [5.8K]

Answer:

<em>f(x) = </em>-\frac{1}{4}<em> x - 2 </em>

Step-by-step explanation:

Slope of the line: m = \frac{y_{2} -y_{1} }{x_{2} -x_{1} }

y - y_{1} = m( x - x_{1} )

f(x) = mx + b (b - is y-intercept)

(0, - 2) Coordinates of y-intercept

(4, - 3)

m = \frac{-3+2}{4-0} = -\frac{1}{4}

<em>f(x) = </em>-\frac{1}{4}<em> x - 2</em>
