What is an equation of a line that passes through the point (-3 -7) and it’s parallel to the line 2x-3y=24
andrew-mc [135]

Answer:

y=(-2/3)x-9

Step-by-step explanation:

1) first put the equation in terms of y. You should get y=-(2/3)x-8.

2) parallel lines have the same slope so the slope for this line and the answer should be the same

3) using the form y=mx+b plug (-2/3) in as the slope or m

4) plug the point in to get your b value. you should have -7 =((-2/3)•(-3))+b

5) isolate the variable b and plug in your answer to the equation.

Which quantity is proportional to 90⁄2? Check all that are true. 45⁄1 15⁄3 180⁄3 180⁄4 270⁄8
Sati [7]

Answer:

45/1 and 180/4

Step-by-step explanation:

1. True

\dfrac{90}{2}=\dfrac{45\cdot 2}{1\cdot 2}=\dfrac{45}{1}

2. False

\dfrac{15}{3}=\dfrac{3\cdot 5}{3\cdot 1}=\dfrac{5}{1}\neq \dfrac{45}{1}

3. False

\dfrac{180}{3}=\dfrac{60\cdot 3}{3\cdot 1}=\dfrac{60}{1}\neq \dfrac{45}{1}

4. True

\dfrac{180}{4}=\dfrac{45\cdot 4}{1\cdot 4}=\dfrac{45}{1}

5. False

\dfrac{270}{8}=\dfrac{135\cdot 2}{4\cdot 2}=\dfrac{135}{4}\neq \dfrac{45}{1}

Aiden borrows a book a public library. He read a few pages on day one. One day two, he reads twice the number of pages than he r
Alisiya [41]

Answer:

110 pages

Step-by-step explanation:

Day 1 =x

Day 2 =2x

Day 3 =x-6

(x)+(2x)+(x-6)=458

Add likes together.

4x-6=458

4x=464.  Divide both sides by 4 to get x. X=116

Day 3=116-6=110

The students in math class use square tiles to make arrays. Celia says they can make more arrays with 8 tiles than with 9 tiles
Cerrena [4.2K]

The students in math class use square tiles to make arrays. If they

  • use 8 (8=1·2·2·2) tiles, then they can form arrays of the length in 1 tile, 2 tiles, 4 tiles and 8 tiles;
  • use 9 (9=1·3·3) tiles, they can form arrays of the length in 1 tile, 3 tiles and 9 tiles (one array less).

So, you can conclude that Celia is correct.
