Step-by-step explanation:

$y = 2x - 24 \\ 4x = 3y \\ 2x = 1.5y \\ y = 1.5y - 24 \\ y - 1.5y = - 24 \\ 0.5y = 24 \\ y = 48 \\ x = \frac{3y}{4} = \frac{3 \times 48}{4} = 36$

x= apples =36 cents

y= pears =48 cents

Quadrilateral ABCD has vertices AC-3.6), B(6,0), C(9. -9), and D(0, -3). Prove that ABCD is a) a parallelogram

Nata [24]

9514 1404 393

Explanation:

The quadrilateral will be a parallelogram if the diagonals bisect each other. That will be the case if the sums of their end-point coordinates are the same.

A + C = (-3, 6) +(9, -9) = (6, -3)

B + D = (6, 0) +(0, -3) = (6, -3)

Both diagonals have their midpoint at (3, -1.5), so the diagonals are mutual bisectors. The figure ABCD must be a parallelogram.

___

The midpoint of AC is (A+C)/2 = (6, -3)/2 = (3, -1.5).

FOR EASY BRAINLIEST ANSWER AND EXPLAIN!! ASAP

horsena [70]

Answer:

Step-by-step explanation:

we know that the total time of the show is 30 minutes.

commercial part = 3x+2

entertainment part = y

also we know that y = 3x +2

y + 3x+2 = 30

we can also say that

2(3(x) +2) = 30

so then

6x +4 = 30

6x = 26

x = 4 $\frac{1}{3}$

4 $\frac{1}{3}$ is the time in minutes for commercials

The numbers of cars (c) in the parking lot increases when the parking fee (f) decrease. Write the correct equation for this scen

vodka [1.7K]

So when one goes up, the other goes down. This is an inverse equation.

An inverse equation looks like this: y = 1/x

In this case, when parking fee (f) decreases, cars (c) increase.
You know which side to put each variable on using the chart they gave you.
f | c
20.00 15 (20.00 = x/15) x=300
30.00 10 (30.00 = x/10) x=300

So your equation in this case is f = 300/c
Knowing that, plug in the fee of 6.00

6 = 300/c Multiply both sides by c.
6c = 300 Divide both sides by 6.
c = 50 cars
