Answer:

x=1      y=2

Step-by-step explanation:

x=1     y=2

8x +4 y=16

8(1) + 4(2)=16

8+8=16

this is correct so now lets check the other one

7y=15-x

7(2)=15-(1)

14=14

this is also correct

Write an equations in point-slope form for a horizontal line that passes through (-4, -1)
Flura [38]

Answer:

Y=-1; y+1=0(x+4)

Step-by-step explanation:

Point slope form: y-y1=m(x-x1)

A horizontal line has a slope of "0" therefore our "m" value is 0

So

y+1=0(x+4)

Y+1=0x+0

y=-1

Hope this helps!

Another easy middle school question​
nekit [7.7K]

Answer:

D

Step-by-step explanation:

Slope-intercept form is [ y = mx + b ] where m = slope and b = y-intercept. We are already given the slope and y-intercept so m = 2 and b = -4.

y = 2x - 4

Best of Luck!

6-2(x+6)=3x+4 <br><br><br> ...............................
juin [17]

Answer:

x=−2

Step-by-step explanation:

1 Expand.

6-2x-12=3x+4

6−2x−12=3x+4

2 Simplify  6-2x-126−2x−12  to  -2x-6−2x−6.

-2x-6=3x+4

−2x−6=3x+4

3 Add 2x2x to both sides.

-6=3x+4+2x

−6=3x+4+2x

4 Simplify  3x+4+2x3x+4+2x  to  5x+45x+4.

-6=5x+4

−6=5x+4

5 Subtract 44 from both sides.

-6-4=5x

−6−4=5x

6 Simplify  -6-4−6−4  to  -10−10.

-10=5x

−10=5x

7 Divide both sides by 55.

-\frac{10}{5}=x

−

5

10

​

=x

8 Simplify  \frac{10}{5}

5

10

​

  to  22.

-2=x

−2=x

9 Switch sides.

x=-2

x=−2
