Answer: 4

Step-by-step explanation:

We can plug in the x and y values into the expression.

Then, we get 2*(-4) + 12.

Because of the order of operations, we calculate 2* -4 first to get -8 +12.

Lastly, we add -8 and 12 to get 4.

8% sales tax is 8% of the sales price = 8% of 's'
8% of 's' = 0.08 × s = 0.08s

The total price = s + 0.08s ⇒ this is the expression

What are the coordinates of A" if it is reflected over the y-axis?

Aleonysh [2.5K]

Answer:

(3,1)

Step-by-step explanation:

When reflecting over the y-axis if the point was on quadrant 1, then the coordinated must be changed like so (x,y) -> (-x,y), so therefore in the scenario, all we have to do is reverse this process. So in this case, Point A is (-3,1) so all we have to do is change the -3 to a positive 3 to the the coordinates of A'' which is (3,1).

What is 3x-2y=24 in slope intercept form??

elixir [45]

Answer: 3x-2y=24 in slope intercept form is $y=\frac{2}{3}x -12$

The graph of the equation is in the attachment

Step-by-step explanation: Slope intercept form is y = mx + b

m is the slope b is the y-intercept x is the "input" in the equation y is the "output" or the y-value in the graph for a given x-value.

You need to rearrange the standard form to slope-intercept to isolate y on the left side of the equation.

3x - 2y = 24 Standard form. Subtract 3x from both sides.

-2y = -3x + 24 divide both sides by -2

-2y/-2 = -3x/-2 + 24/-2 . Simplify.

y = 3x/2 - 12 .

To clarify the slope as a fraction

$y=\frac{2}{3}x -12$
