20 Points! Which ordered pair is the best estimate for the solution of the system of equations?
yan [13]

Answer:

The best estimate for the solution is the ordered pair  (-6.5,-3.5)

Step-by-step explanation:

we have

y=\frac{3}{2}x+6 ------> equation A

y=\frac{1}{4}x-2 ------> equation B

we know that

using a graphing tool, the solution of the system of equations is the intersection point both graphs

The intersection point is (-6.4,-3.6)

therefore

The best estimate for the solution is the ordered pair  (-6.5,-3.5)

The amount Diego charges to detail an SUV is proportional to the time it takes him to detail the vehicle. Diego charges $37.50 t
prisoha [69]

Answer:

d = 15h

Step-by-step explanation:

Given

Charges\ \alpha\ Time

Represent charges with d and time with h

So:

d = \$37.50 when t = 2.50\ hours

Required

Determine the formula

Charges\ \alpha\ Time

In other words,

d\ \alpha\ h

Convert to an equation

d = k * h

Where

k = constant of proportion

Substitute values for Charges and Time

37.50 = k * 2.5

Solve for k

k = 37.50/2.50

k = 15

Substitute 15 for k in d = k * h

d = 15 * h

d = 15h

<em>The above formula models the situation</em>
