Solve by substitution <br>-4x-2y=-12 <br>4x+8y=-24

kykrilka [37]

I hope this helps you

-4x-2y+4x+8y= -12-24

6y= -36

y= -6

-4x-2. (-6)= -12

-4x+12= -12

-4x= -24

x=6

Find the area of the shaded region

wariber [46]

31x^2 + 53x - 8

Use the FOIL method to find the area of the large rectangle. (7x - 2)(9 + 5x)

First term in each binomial: 7x * 9 = 63x
Outside terms: 7x * 5x = 35x^2
Inside terms: -2 * 9 = -18
Last term in each binomial: -2 * 5x = -10x

Now, just add them all up.

63x + 35x^2 - 8 - 10x

35x^2 + 53x - 8

Now find the area of the square.

2x * 2x = 4x^2

Now, subtract the areas.

31x^2 + 53x - 8

Lauren drove The 75 miles to the coast at 75 mph, but gets stuck in traffic and averaged 25 mph on the way back. How many total

aksik [14]

Answer:

150 miles

Step-by-step explanation:

In this problem, we are only interested in the distance that Lauren drove, this means that her average speed (75 mph to the cost, and 25 mph on the way back) does not matter since the distance remains the same. If one leg of trip is 75 miles long, the total mileage for the round trip is:

$M=75+75\\M=150\ miles$

Lauren drove 150 miles.
