Select all the statements that can be determined from the table given

Maurinko [17]

Answer:

Statements A and D

Step-by-step explanation:

A. Since all of the values surrounding x = 0.5 reflect across that point, there is a line of symmetry at x = 0.5

B. This is not a y intercept since in the point (-12,0) the x value is not zero and at y intercepts, it should be zero.

C. Same thing from statement B, the y value for the x intercepys should be zero, not 4 or -3.

D. To help visualize this, take the slope of the secant line from x = -4 to x = 0.

(8 - (-10))/(-4 - 0) = 18/(-4) or -9/2. Since the slop is negative, the function is decreasing on this interval.

Ivanna bought a desktop computer and a laptop computer. Before finance charges, the laptop cost $450 less than the desktop. She

GarryVolchara [31]

Solution:

According to the problem, the laptop costs $450 less than the desktop. Let x the cost of the laptop, then we get the following equation:

$x\text{ + 450 = cost of the desktop}$

now, the total finance charge of $409 is from 9% of the cost of the laptop and 6.5% of the cost of the desktop. According to this, we get the following equation:

$0.09(x)+0.065(x+450)=409$

Applying the distributive property, we get:

$0.09x+0.065x+29.25=409$

now, placing like terms on each side of the equation, we get:

$0.09x+0.065x=409-29.25$

this is equivalent to:

$0.155x\text{ = 379.75}$

solving for x, we get:

$x\text{ = }\frac{379.75}{0.155}=2450$

this means that:

The cost of the laptop is x = 2450

and

The cost of the desktop is x+450 = 2450 +450 = 2900.

So that, we can conclude that the correct answer is:

Cost of the laptop = 2450

Cost of the desktop =2900.

Answer:

x < 12.64

Step-by-step explanation:

The constants on the left cancel, so the inequality simplifies to ...

0.5x < 6.32

Multiply by 2 to get the solution:

x < 12.64
