Answer:

see explanation

Step-by-step explanation:

The perimeter (P) of a rectangle is calculated as

P = 2l + 2w ( l is the length and w the width )

perimeter of rectangle A = 2(7) + 2(5) = 14 + 10 = 24 in

perimeter of rectangle B = 2(4x - 3) + 2x = 8x - 6 + 2x = 10x - 6 in

Equating the two gives

10x - 6 = 24 ( add 6 to both sides )

10x = 30 ( divide both sides by 10 )

x = 3

Thus

length of rectangle B = 4x - 3 = 4(3) - 3 = 12 - 3 = 9 in

Width of rectangle B = x = 3 in

NEED HELP ASAP !! PLEASE !!!
algol [13]

Answer:

The domain for A is 0, 1, 2, 3 and the range is 0, 5, 10, 15

and the domain for B is 2, 2, 4, 4 and the range is 4, 3, 2, 1

Only A is a function because for the same input value in B, there is two different output values which is not possible.

Step-by-step explanation:

I just wanna let you know so you don't waste any more points for us, but the domain is the x-values/ input/ stuff on the left of a given point. The range is the y-values, the output, and the stuff on the right side of a given point. So on (1, 7) for example, the 1 would be the domain number and the 7 would be the range number.

The y-axis values are the output/range and the x-axis values are the input/domain.

Hope this helps bro

Find the value of y for the following system of equations 5x + 3y = 10 x = y - 6
viktelen [127]

Answer:

x = -1 , y = 5

Step-by-step explanation:

Solve the following system:

{5 x + 3 y = 10 | (equation 1)

x = y - 6 | (equation 2)

Express the system in standard form:

{5 x + 3 y = 10 | (equation 1)

x - y = -6 | (equation 2)

Subtract 1/5 × (equation 1) from equation 2:

{5 x + 3 y = 10 | (equation 1)

0 x - (8 y)/5 = -8 | (equation 2)

Multiply equation 2 by -5/8:

{5 x + 3 y = 10 | (equation 1)

0 x+y = 5 | (equation 2)

Subtract 3 × (equation 2) from equation 1:

{5 x+0 y = -5 | (equation 1)

0 x+y = 5 | (equation 2)

Divide equation 1 by 5:

{x+0 y = -1 | (equation 1)

0 x+y = 5 | (equation 2)

Collect results:

Answer: {x = -1 , y = 5
