Jason's business computers need servicing. The expression 81x + 108 represents a contractor's total charges in dollars for fixin

Zielflug [23.3K]

Answer:

The Jason's company charges more than the contractor's company.

Step-by-step explanation:

There are two expressions given for total charges for two companies as 81 x+108 and 103 x+64.

Here x represents number of hours.

We are asked to find difference in total charges if that takes 45 minutes.

45 minutes = $\frac{3}{4}$ hours.

Plug in this value for x.

81x+108 = $81*\frac{3}{4} +108$

Simplify it

60.75 +108 =168.75

Now, for 103x+64 = $103 *\frac{3}{4} +64$

Simplify it,

77.25+64=141.25

If we see the total charge for both companies for 45 minutes, the Jason's business computers charges more than contractor's company.

valina [46]

Answer:

-2

Step-by-step explanation:

Start with the vertex form of the equation of a parabola: y - k = a(x - h)^2

Here h = -2, k = -3, x = -1, y = -5. Find a:

-5 - [-3] = a(-1 - [-2])^2, or

-5 + 3 = a(1)^2, or

-2 = a

The unknown coefficient is -2.
