Answer:y=2x+4

explanation:

−10x+5y=20

Step 1: Add 10x to both sides.

−10x+5y+10x=20+10x

5y=10x+20

Step 2: Divide both sides by 5.

5y=10x+20

5. 5

Y=2x+4

9= 2/3 (x+12) plz help
avanturin [10]

Answer:  x=3/2  

Step-by-step explanation:

Multiply the parentheses by 2/3.  9=2/3x+8.

Multiply  both sides by 3 .  27=2x+24

Move the term. When moved to the left side it changes from positive to a negative.  -2x=24-27.

-2x=-3

Divide both sides by -2

x=3/2   (x=1 1/2, x=1.5)

<u>Given </u><u>:</u><u>-</u>

  • The slope of the line through points (3,y) and (4,10) is 7 .

<u>To </u><u>Find</u><u> </u><u>:</u><u>-</u>

  • The value of y .

<u>Solution</u><u> </u><u>:</u><u>-</u>

As we know that the slope of the line is difference of ordinate divided by the difference of absicca as ,

\longrightarrow m = y -10 / 3 - 4

\longrightarrow 7 (-1) = y -10

\longrightarrow -7 = y -10

\longrightarrow y = 10 -7

\longrightarrow y = 3

<u>Hence</u><u> the</u><u> required</u><u> answer</u><u> is</u><u> </u><u>3.</u>
