Foundation Geometry Midpoint Of AC A. 18B. 6C.27D.54

Answers

Answer 1

Answer:

D

Step-by-step explanation:

Since B  is the midpoint of AC , then

AB = BC , substitute values

4x + 3 = 3x + 9 ( subtract 3x from both sides )

x + 3 = 9 ( subtract 3 from both sides )

x = 6

Then

AC = AB + BC

     = 4x + 3 + 3x + 9

     = 7x + 12

     = 7(6) + 12

     = 42 + 12

    = 54 → D

What is the equation of the line —3x – 2y = 30 in slope-intercept form?

Answers

Answer:

2nd option

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

- 3x - 2y = 30 ( add 3x to both sides )

- 2y = 3x + 30 ( divide terms by - 2 )

y = - [tex]\frac{3}{2}[/tex] x - 15 ← in slope- intercept form

I really need help finding the solution!!

Answers

Answer:

-0.5 is not a solution

2 is a solution

Step-by-step explanation:

To check if something is a solution of the equation, you need to substitute the value in place of the variable

15 + 2y = -12 - 4y

15 + 2(-0.5) = -12 - 4(-0.5)

15 - 1 = -12 + 2

14 ≠ -10 ∴ -0.5 is not a solution

5 - 2(3x + 5) = 3 - 10x

5 - 2[3(2) + 5] = 3 - 10(2)

5 - 2(6 + 5) = 3 - 10(2)

5 - 12 - 10 = 3 - 120

-17 = -17 ∴ 2 is a solution

Other Questions
What do I do?Backstory)) Today as I was waking to lunch with a few people that were my so called friends, they are in the dance team and they wanted to go and help sell tickets there was one small table to sell tickets. But the thing is that there is only room for about 4 people on that table but they fit 7 which logically I think we all know that 7 people dont need to sell tickets, only if 2 people actually bought tickets So as we entered the cafeteria I followed them (I am not on the dance team) they went to that very table then I asked the obvious question where should I sit? Cause there want room for me. Then one of my friends pointed at an empty table and told me to sit there. I sit there the whole lunch eating only a few. I am stressed when nobody is next to me eating which causes me to eat less. Cause I feel everyone is staring at me. So I act like I am fine. Then after that we had some free time. I went to the bathroom the whole free time to just cry. But the thing is as the free time started they didnt come and get me they just walked off so thats why I went to the restroom and stayed in there for a little till the bell rang.So what should I do they are going to do the same thing tomorrow and I am getting stressed cause I have no other friends to sit with.
