Answer:

Midpoint of (-6, 3) and (8, -7) is: (1, -2)

Step-by-step explanation:

Given the points

Computing the midpoint of (-6, 3) and (8, -7) using the formula

⇒  [tex]\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-6,\:3\right),\:\left(x_2,\:y_2\right)=\left(8,\:-7\right)[/tex]

⇒  [tex]\left(\frac{8-6}{2},\:\frac{-7+3}{2}\right)[/tex]

⇒  [tex]\left(1,\:-2\right)[/tex]

Therefore, Midpoint of (-6, 3) and (8, -7) is: (1, -2)

Answer:

B. 56°

Step-by-step explanation:

[tex] 20 \degree = \frac{1}{2} (96 \degree - \widehat{LN}) \\ \\ 2 \times 20 \degree = (96 \degree - \widehat{LN}) \\ \\ 40 \degree = (96 \degree - \widehat{LN }) \\ \\ \widehat{ln} = 96 \degree - 40 \degree \\ \\ \huge \red{ \widehat{LN} = 56 \degree}[/tex]

Answer:

10:18

Step-by-step explanation:

Answer:

the ordered pair will be (1, 2)

Step-by-step explanation:

first of all substitute the x and y values into the equation in other to make the equation true.

Therefore y=4x-7

1 = 4(2) -7

1 = 8 -7

1 = 1

Making the first equation true. then move to the second equation which is y = - x + 3

1 = -(2) + 3

1 = 1

Answer:

32+10=7x

Step-by-step explanation:

Let's solve this first. 32$ is the final price, and then add 10$ because of the gift card, leaving you with 42$. Divide the 42 by 7, because each CD is 7 dollars. The result is 6. So put that into an equation.

32+10=42=7x

x=6!

Answer:

Volume is dependent on how hard the air is pushed through. Sound travels more slowly than light. Sound waves travel at the same speed, but vibrate in different ways. Some vibrate quickly and have a high frequency or pitch, while others vibrate slowly and give a lower pitch.

Answer:

3/5

Step-by-step explanation:

y=3/5x = 0                 x both sides by 5

5y-3x=0                     reorder terms (community property)

-3x+5y=0

3x-5y=0                                changes the signs when you do that

Answer:

$15.98

Step-by-step explanation:

25% off means it is 75% of its normal cost

0.75 x 20 = 15

The scarf is $15 after 25% discount. Then we calculate its final cost after tax:

6.5% = 0.065

1.065 x 15 = 15.975 which rounds to $15.98

Answer: 15.98

Step-by-step explanation: 25% off 20 is 15. 6.5% times 15 is .98 so the answer is 15.98

Answer:

x= 8

Step-by-step explanation:

Step 1- Distribute into the parenthesis by 1.

4x+2+3(-1)+3(-1)x= 7

Step 2- Simplify.

4x+2-3-3x= 7

Step 3- Add common variables.

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

1x-1= 7

Step 4- Add 1 to both sides.

1x-1= 7

 +1  +1

1x= 8

Step 5- Divide both sides by 1.

1x= 8

1    1

x= 8

Can you give me a Brainliest

plz plz plz plz plz plz

Answer:x=8

Step-by-step explanation:

4x+2-(3+3x)=7

Distribute -1 in parentheses because there is an invisible 1

4x+2-3-3x=7

Combine like terms

X-1=7

Add one on both sides

x=8

Step-by-step explanation:

Answer:

Option (B)

Step-by-step explanation:

Since the linear graph is passing through the origin, there is a proportional relationship between the amount of chocolate (C) and amount of peanuts (P) used in the package of snacks mix,

P ∝ C

P = kC

k = [tex]\frac{P}{C}[/tex]

Here k = proportionality constant

Since, the given line passes through a point (3, 2),

k = [tex]\frac{2}{3}[/tex]

Therefore, ratio of chocolate and peanuts mixed is [tex]\frac{2}{3}[/tex].

Option (B) is the correct option.
