|3y+7|-10=-5 add 10 to both sides

|3y+7|=5 now since this is an absolute value equation we must solve for both the positive and negative solutions...

3y+7=5 subtract 7 from both sides

3y=-2 divide both sides by 3

y=-2/3

Now

3y+7=-5 subtract 7 from both sides

3y=-12 divide both sides by 3

y=-4

So y=-2/3 and -4

Find p(0),p(1),p(-1) and p(2) of the 3x(x-2)

Effectus [21]

Answer:

make x→0

$p(0)=(0)^{2}-3(0)+2$

→ $p(0)=0+0+2$

→ $p(0)=2$

$------$

Replace x→-1

$p(-1)=(-1) ^{2} -3 (-1)+2$

→ $p(-1)=1-3+2$

→ $p(-1)=0$

$----------$

Now make x→2

$p(2)=(2) ^{2} -3(2)+2$

→ $p(2)=4-6+2$

→ $p(2)=0$

$Answer:-2,0,0$

$-----------$

hope it helps...

Thepotemich [5.8K]

Floyd's contract consists of
(i) $200 per month fixed.
(i) $12 per album sold.

Let x = number of albums sold last month.
Because total earnings is $644, therefore
200 + 12x = 644

To find x, do the following:
Subtract 200 from each side.
12x = 644 - 200 = 444
Divide each side by 12.
x = 444/12 = 37

Answer:
The equation is 12x + 200 = 644.
The solution for x (number of albums sold) is 37.

nu is designing a rectangular sandbox. the bottom is 16 square feet. which dimensions require the least amount of material for t

SCORPION-xisa [38]

Answer:

The least amount of dimensions would be using a 4ft x 4ft base.

Step-by-step explanation:

When looking to maximize area and minimize materials, a perfect square always does this. To prove the point, consider the 4 x 4 box in the answer to say a 16 x 1 box, which would have the same area.

The 4 x 4 box would have 4 sides each of 4 ft. Therefore, it would have 16 feet of sides to construct.

Meanwhile, there would be two sides on the other one that were 16 ft alone.
