Which equation is an identity?

Mathematics
1 answer:
miskamm [114]3 years ago
5 0

Answer:

D

Step-by-step explanation:

To be an identity we require both sides of the equation to equate

A

8x + 9 ≠ 8x - 3 ← not an identity

B

7x - 2 = 8x + 4 - x = 7x + 4 ≠ 7x - 2 ← not an identity

C

11 - (2x + 3) = 11 - 2x - 3 = - 2x + 8 ≠ - 2x - 8 ← not an identity

D

5x + 8 - x = 6x - 2(x - 4), that is

4x + 8 = 6x - 2x + 8 = 4x + 8 ← both sides equate thus an identity

Answer:

$23271.49

Step-by-step explanation:

The function C(t) = C(1 + r)^{t} models the rise in the cost of a product that has a cost of C today, subject to an average yearly inflation rate of r for t years.

Now, if the average annual rate of inflation over the next 8 years is assumed to be 2.5% then we have to find the inflation-adjusted cost of a $19100 motorcycle after 8 years.

Therefore, the cost will be C(8) = 19100(1 + \frac{2.5}{100} )^{8} = 23271.49 dollars. (Answer)

The measure of an angle is 140°. What is the measure of its supplementary angle
Darina [25.2K]

Answer:

40 degrees

Step-by-step explanation:

Supplementary angles are angles in which their measures combined add up to 180 degrees. So we can set up an equation:

140+x=180

x=40

So the other supplementary angle is 40 degrees
