-What is the midpoint between the points (7, 3) and (-5, 5)?

Answers

Answer 1

Answer:

Answer:

The midpoint is ( 1,4)

Step-by-step explanation:

To find the x coordinate of the midpoint add the x coordinates of the endpoint and divide by 2

( 7+-5)/2 = 2/2 =1

To find the y coordinate of the midpoint add the y coordinates of the endpoint and divide by 2

( 3+5)/2 = 8/2 =4

The midpoint is ( 1,4)

A contractor is pouring a concrete driveway. The perimeter is 108 ft. What length will the driveway be if the width is 14 ft.?. . The driveway is ____ feet long.

Answers

The Perimeter = 2 L + 2 W
108 = 2 L + 2 · 14
108 = 2 L + 28
2 L = 108 - 28
2 L = 80
L = 80 : 2
L = 40 ft
Answer: the driveway is 40 feet long.

Answer:

a. B

b. 4

c. BD

Step-by-step explanation:

a. Point A is at -7; point D is at +1. The distance between these points is ...

1 -(-7) = 8

The midpoint will be 8/2 = 4 units from either end so will be at ...

A +4 = -7 +4 = -3

D -4 = 1 -4 = -3

The point located at -3 is point B, the midpoint of AD.

b. Having done the above calculations, we know that segment AB is 4 units long.

c. We also know that segment BD is 4 units long. That is because the midpoint divides a segment into two equal parts.

Work out (25/9) to the power of -3/2

Answers

To work out (25/9) to the power of -3/2, we can use the property of exponentiation. The negative exponent signifies taking the reciprocal of the base raised to the positive exponent. Additionally, the fractional exponent indicates taking the square root of the base raised to the numerator and then taking the reciprocal of the result raised to the denominator. Let's calculate it step by step.

Help, 3+7x=12, what is x?

Answers

So just your normal equation.
We need to isolate x alone.
First lets write out our equation
3 +7x = 12

Lets do this step by step.

first subtract 3 from both sides.
3 + 7x = 12
-3 = -3 it cancels out on the left side and we solve on the right side.
*************
7x = 9

second we divide both sides by 7
7x = 9
÷7 = 7 we got the x alone and we just write 9/7 as our answer.

x = 9/7

Or as a decimal.
9/7 could be 1.28571428571429

Either will work.
x = 9/7
or
x = 1.28571428571429

Have a nice day. :)
