Answer: B. (6,4)

Find x for the 2nd equation

3x + 6y = 42

3x = 42-6y

x= (42-6y) / 3

Place the value of x in the first equation and find for y then.

4x - 3y= 12

4{(42-6y)/3} - 3y = 12

So the answer for y is 4

Now, you know the value of y is 4.

4x - 3*4 = 12

4x - 12 = 12

x= 12+12 /4

x= 6

So x is 6 and y is 4. So the answer is B.

Y+7=-2(x-1)<br><br><br> hurry plz
zhannawk [14.2K]

Answer:

y=-2x-5

Step-by-step explanation:

First of all, you have to distribute -2 to (x-1) to get to this equation y+7=-2x+2.  Then, you subtract 7 on both sides to get the slope-intercept of y = -2x - 5.

Answer:

A. the area of the large pond is 16 times the area of the small pond

Step-by-step explanation:

let's say 4 is the radius of the small circle, which means the area is 50.26548

if the large circle is 4 times the small circle, that means it's radius is 16 which means the area is 804.24772

so if you divide the big circle area by the small circle area:

804.24772/50.26548

it gives you 16.00000079577 which is rounded to 16

therefore, the bigger circle is 16 times bigger than the smaller circle

Is shipping box is a shape of a cube. Each side measures 3c^6d^2 inches. Express the volume of a cube has a monomial.
liubo4ka [24]
Length of each side of cube is = 3c^6d^2

SO the volume of cube = (Side)^3
                                      = (3c^6d^2)^3
                                      = 27 * (c^6)^3(d^2)^3
                                      = 27c^{18}d^6

SO the volume of cube is 27c^{18}d^6

Blake solved the following division exercise : 136 divided by 3 = 44 R4. Explain how you know the answer is wrong just by lookin
son4ous [18]
The remainder (which is what Blake says is the remainder), can never be more than the number you are dividing by (the dividend), which in this problem is three.

Divide 136 by 3 and you will prove that answer is incorrect.
