A computer store changed the price of a laptop. It was originally $900, but now it is $1,100.Find the percent of change

tigry1 [53]

Answer:

The percent of change is 22.22%.

Step-by-step explanation:

You can calculate the percent of change by subtracting the original number from the final number and dividing that by the original number. Then, you have to multiply the result for 100:

percent of change=((1,100-900)/900)*100

percent of change=(200/900)*100

percent of change=22.22%

According to this, the answer is that the percent of change is 22.22%.

Find the range of the following equation for the domain {-4, 0, 3} f (x) = -2x^2 -3

Tamiku [17]

The range of the function is {-34, -2, -20}

<h3>How to determine the range?</h3>

The function is given as:

f(x) = -2x^2 - 2

The domain is {-4, 0, 3}

Substitute the domain values in the function.

f(-4) = -2(-4)^2 - 2 = -34

f(0) = -2(0)^2 - 2 = -2

f(3) = -2(3)^2 - 2 = -20

This means that the range of the function is {-34, -2, -20}

HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

andre [41]

Answer:

Option A is correct.

Step-by-step explanation:

If Δ YES ∼ Δ NOT, then it means that ΔYES and ΔNOT are similar triangles.

The similar triangles means that all the corresponding angles of the two triangles are same i.e. ∠ Y = ∠ N, ∠ E = ∠ O and ∠ S = ∠ T

Therefore, according to the property of similar triangles we can write that

$\frac{NO}{YE} = \frac{OT}{ES} = \frac{NT}{YS}$ .

Therefore, option A is correct.

which graph represents the solution set of the system of inequalities? (is my selected answer correct, if not please help!!)

algol [13]

Answer:

the graph on the right-top

Step-by-step explanation:

Transferring an "x" to the right side in $x+y\ge-3$ , we get $y\ge -x-3$

The system of inequalities is

$\left \{ {{y$

We have y=2x+2 - ascending function with a=2, b=2

b=2 shows that ascending function intersects Y-axis is in y=2 - that situation is only on the right-top and left-down. So, we refuse left-top and right-down.

y=-x-3 - descending function with a=-1, b=-3

y<2x+2 is an area below the ascending function and we see that on the left-

$y\ge-x-3$ is an area above the descending function

On the left-down we have an area above both functions, so we refuse this picture

Right-top is correct
