What’s the x and y intercepts of this equation: -3x-7y=84
Arlecino [84]

Answer:

The X and Y intercepts to the equation -3x - 7y = 84 is

x-intercept (s): (−28,0)

y-intercept (s): (0,−12)

Step-by-step explanation:

To find the x-intercept(s), substitute in 0 for y and solve for x

−3x−7⋅0=84

Solve the equation.

x=−28

x-intercept(s) in point form.

x-intercept (s): (−28,0)

To find the y-intercept(s), substitute in 0 for x and solve for y .

−3⋅0−7y=84

Solve the equation.

y=−12

y-intercept(s) in point form.

y-intercept (s): (0,−12)

Hope this helps.

For which value of x is the equation 3(3 + x) = 15 + x true?<br> A) 1 <br> B) 2 <br> C) 3 <br> D) 4
natulia [17]

Answer:

C

Step-by-step explanation:

3(3 + x) = 15 + x

Open bracket

9 + 3x = 15 + x

Collecting like terms

3x - x = 15 - 9

2x = 6

Dividing by 2

x = 6/2

x = 3

How to solve -18=6y+6(1+3y)
slamgirl [31]

Answer:-1

Step-by-step explanation:

I rewrote it so it looks like this:

6y+6(1+3y)=-18

6y+6(1)+6(3y)=-18

6y+6+18y=-18

24y+6=-18

     <u> -6   -6</u>

<u>24y</u>=<u>-24</u>

24      24

y=-1
