9x - 4y= 19
4x + 4y= 20

Answers

Answer 1

Answer:

x=3 and y=2

Step-by-step explanation:

9x - 4y= 19

4x + 4y= 20

add both equations;

13x = 39

x= 3

using 4x + 4y= 20;

4(3) +4y=20

12+4y=20

4y= 20-12=8

y=8/4=2

Find the value
of 6y^2 - 24y - 51 when y=-2

Answers

Answer:

21

Step-by-step explanation:

6(y^2) - 24y -51 = 6 4 - 24y - 51

(6 4) - (24y) - 51 = 24 - -48 - 51

(24 - -48) - 51 = 72 - 51

72 - 51 = 21

Step-by-step explanation:

We are asked to find a slope whilst given a graph.

To solve for slope, we must pick two coordinate points that are not decimals and following the formula of rise over run, which in basic terms y over x.

So based on what I see, I can see (1, 1) and (2, 5).

The rise over run is as followed :

[tex]\frac{y2 - y1}{x2 - x1}[/tex]

2 and 1 meaning the first and second number within the coordinate, so substitute :

[tex]\frac{5 - 1}{2 - 1}[/tex]

[tex]\frac{4}{1}[/tex]

Divide :

[tex]4[/tex]

4 is our slope.

D. x=72
30 POINTS TO THE RIGHT ANSWER AND BEST EXPLANTION.

Answers

Answer: D. x=72

Step-by-step explanation:

With the equation x/8-6=3  we can start solving by first moving the "-6"

                 x/8-6(+6)=3(+6)

                 x/8=9             <-- Rewrite equation after adding "6" to both sides

                 x/8(*8)=9(*8)  <--- Multiply both sides by 8

                 x=72              <-- After multiplying, solution is found
