Answer: that’s complicated ;-;

Step-by-step explanation:

Answer:

The answer is

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

G(1,7) and H(-3,11)

The midpoint is

[tex]M = ( \frac{ - 1 + 3}{2} , \: \frac{7 + 11}{2} ) \\ = ( \frac{2}{2} \: , \: \frac{18}{2} )[/tex]

We have the final answer as

Hope this helps you

Answer:

7. 24

8. -1

9. 28

10. 24

Step-by-step explanation:

substitute values into equations. don't forget the brackets :))

7. 3x + 2y2 Let x = 4, y = 3

= 3(4) + 2(3)2

= 12 + 12

= 24

8. (x + 2)2 - (3x - 2) - 4 Let x = 3

= ((3) + 2)2 - (3(3) - 2) - 4

= (5)2 - (9 - 2) - 4

= 10 - 9 + 2 - 4

= -1

9. x + 2y - 3z + xyz Let x = 4, y = 3, z = 2

= (4) + 2(3) - 3(2) + (4)(3)(2)

= 4 + 6 - 6 + 24

= 28

10. xyz Let x = 4, y = 2, z = 3

= (4)(2)(3)

= 24

Answer:

4

Step-by-step explanation:

First n(AUB)=n(E) - n((AUB)')

So n(AUB) = 40 - 6 = 34

Now all u hv to do is use the formulae,

n(AUB) = n(A) + n(B) - n(ANB)

So when u substitute above values,

34=22 + n(B) - 8

So,

n(B) = 4

Answer:

11

Step-by-step explanation:

QS = QR + RS ➡ 19 = -1 + x + 2x - 7 add like terms

19 = 3x - 8

27 = 3x

9 = x

RS = 2x - 7 so 2×9 - 7 = 11

Answer:

5 hours?

Step-by-step explanation:

normally, two people would cut the time in half, but she takes forever.   half of 12 is 6, half or 8 is 4, so 5, right? the medium answer

Answer:

Step-by-step explanation:

This excercise, focuses on ratio problem, and it has to do with the representation of ratio, since we can represent ratio in different ways. let us represent this ratio in the normal/ usual format.

we will first reduce the given value and represent it in the ratio format

given that for  roller skate race, 48 are boys and,

roller skate race, 64 are girls

we have the ratio as

=48/64 divide both denominator and numerator by 4

=12/16  further divide both denominator and numerator by 4

=3/4

The ratio is 3:4

Answer:

it is going to have to be the 3rd one

Answer:

[tex]\large\boxed{x = 7}[/tex]

Step-by-step explanation:

3x - 2(x + 3) = 4x - 9 - x

Start by multiplying 2 by the values in the parenthesis

3x - 2x + 6 = 4x - 9 - x

Subtract 3x - 2x and 4x - x

x + 5 = 3x - 9

Add 9 to both sides of the equation

x + 14 = 3x

Subtract x from both sides of the equation

14 = 2x

Divide both sides of the equation by 2

[tex]\large\boxed{x = 7}[/tex]

1.) The total effect of 90% of the $1,000 tax rebate would be 10,000 growth in the economy. Second question, the total effect of 90% of $5,000 would be 50,000 in growth in the economy. *Same concept different amount.

Step-by-step explanation:

1. S=[tex]\frac{a_1{} }{1-R}[/tex]             2. S=[tex]\frac{a_{1} }{1-R}[/tex]

   S=[tex]\frac{1000}{1-0.9}[/tex]               S=[tex]\frac{5,000}{1-0.9}[/tex]

   S= 10,000          S=50,000

Answer:

Step-by-step explanation:

3/5 divided by 7/10

You use KCF

KCF stands for keep change flip

So it would be 3/5x10/7

3              10                    15

_      x       _        =            _

5               7                       7

you need to simplify it so the 5 in 3/5 would be a 1 and the 10 in 10/7 would be  5

Answer: x = 4

Step-by-step explanation:

1.25(4x-10)=7.5

5x-12.5 = 7.5

5x = 20

x = 4

Answer:

x=4

Step-by-step explanation:

1.25(4(4)-10)=7.5

1.25(16-10)=7.5

1.25(6)=7.5

7.5=7.5

Answer:

Was the question meant to say "what is the value of 4x-7 when x=4?" if so the answer is 9.

Step-by-step explanation:

First plug in 4 for x. The equation should then read 4(4) -7

Next use pemdas to solve (multiple 4 × 4 and then subtract 7 to get the answer 9
