Solve the system using any method.<br> y = 3x + 2<br> y = 7x - 10

Marysya12 [62]

Answer:

x=3

y=11

Step-by-step explanation:

y = 3x + 2 equation 1

y = 7x - 10 equation 2

using equation 1 in equation 2 we have:

3x + 2 = 7x - 10

2=7x - 3x -10

2 = 4x -10

2+10 = 4x

12= 4x

12/4 = x

we have:

x= 3

using equation 1:

y = 3x + 2

y= 3(3)+2

y=9+2

y=11

Suppose a+b=0 so what equals a-b

AURORKA [14]

Answer:

a-b = 2a

a-b = -2b

Step-by-step explanation:

a+b = 0

Subtract b from each side

a+b - b=0-b

a = -b

a-b =

Replace a with -b

-b -b= -2b

a = -b

Divide by -1

-a =b

or replace b with -a

a - (-a)

a+a

A cube with a volume of 75 cmis dilated by a factor of 5.

Rashid [163]

The volume of the dilated cube is $9375 \ {cm}^{3}$

Explanation:

The volume of the cube is $75 \ {cm}^{3}$

It is given that the cube is dilated by a factor of 5.

We need to determine the volume of the dilated cube.

Since, we know that the dilation is a transformation that changes the size of the image but not the shape.

Since, it is given that the volume of the cube is dilated by a factor of 5, the length of the image will be 5 times greater, the width of the image will be 5 times greater and the height of the image will be times greater than the original image.

Thus, the volume of the dilated cube is given by,

$Volume = (5\times5\times5)(volume \ of \ the \ original \ cube)$

$= (5\times5\times5)(75)$

$=(125)(75)$

$=9375 \ {cm}^{3}$

Thus, the volume of the dilated cube is $9375 \ {cm}^{3}$
