-x+y=4 3x-2y=-7 substitution

Answers

Answer 1

Answer: -x+y=4 add x to both sides to get y=x+4 Plug x+4 into the equation for y to get 3x-2(x+4)=-7 Distribute to get 3x-2x-8=-7 Add 8 to both sides to get 3x-2x=1 Subtract 3x-2x to get x=1 the answer is 1

Square EFGH stretches vertically by a factor of 2.5 to create square E′F′G′H′. The square stretches with respect to the x-axis. If point H is located at (-2, 0), what are the coordinates of H?A.(-5, 0)
B.(-2, 0)
C.(0.5, 0)
D.(-2, 2.5)

Answers

Square EFGH stretches vertically by a factor of 2.5 to create square E′F′G′H′. The square stretches with respect to the x-axis. If point H is located at (-2, 0), the coordinates of H will be at point "D.(-2, 2.5)." Since it stretches vertically, it assumed that it stretches all parallel with the y axis.

Answer with explanation:

Pre -image= Square E F G H

Image=Square E′F′G′H′

Vertical Stretch Factor= 2.5

Coordinates of Point H= (-2,0)

If, (x,y), is the coordinate of any point, and , m is vertical stretch factor,then coordinate of Image =(x, my)

→Here, Vertical stretch, factor is 2.5,and coordinates of H=(-2,0) then Coordinates of H' will be =(-2, 0×2.5)=(-2,0)

Option B: (-2,0)

How many months are in 6 years?

Answers

In one year, there are 12 months. So, to find out the amount of months there are in 6 years, all we need to do is multiply 12 * 6.

12 * 6 = 72

And that is our answer.

There are 72 months in 6 years.
Hope that helped =)

We can see here that there are 72 months in 6 years. It is gotten by multiplying 12 months by 6 years.

What is month?

A month is a unit of time commonly used in calendars to divide a year into shorter periods. It is based on the approximate time it takes for the Moon to orbit the Earth, which is roughly 29.5 days. To account for the varying lengths of months, the Gregorian calendar, the most widely used civil calendar, has months of different durations: 28, 30, or 31 days.

To calculate the number of months in a given number of years, you multiply the number of years by 12 since there are 12 months in a year. Therefore, 6 years multiplied by 12 months equals 72 months.
