B
[tex]6x + 8y = - 2 \\ [/tex]
B is a multiple of A
[tex]3x + 4y = - 1 \\ if \: multiplied \: by \: 2 \\ = 6x + 4y = - 2[/tex]
and since the two systems A and B
have
[tex]2x + y = 5[/tex]
then the two systems have the same solution

Answer:
2/3 y + 5/6 x
Step-by-step explanation:
what you get when u combine like terms:
2/3 y + 5/6 x
Answer:
[tex]\frac{5}{6}x+\frac{2}{3}y[/tex]
Step-by-step explanation:
The first thing we should do is change all the denominators to the lcm, which is 6.
[tex]\frac{1}{2}x+\frac{1}{3}y+\frac{1}{3}x+\frac{1}{3}y\\\\\frac{3}{6}x+\frac{2}{6}y+\frac{2}{6}x+\frac{2}{6}y[/tex]
Now we just combine like terms
[tex]\frac{3}{6}x+\frac{2}{6}y+\frac{2}{6}x+\frac{2}{6}y\\\\\frac{5}{6}x+\frac{4}{6}y[/tex]
Now we got the answer but we should still simplify the [tex]\frac{4}{6}[/tex], so it will end up being [tex]\frac{2}{3}[/tex]. So the expression would look like this.
[tex]\frac{5}{6}x+\frac{2}{3}y[/tex]

What is the inverse of y=2/3x-5
Answers
The inverse of y=2/3x-5 is 3/2x + 15/2
What is inverse function?An inverse is a function that serves to “undo” another function.
Given a function, y = 2/3x -5
Exchange x and y
x = 2/3y -5
Solve for y
Add 5 to each side
x+5 = 2/3y-5+5
x+5 = 2/3y
Multiply each side by 3/2
3/2(x+5) = 3/2*2/3y
3/2x + 15/2 =y
Hence, The inverse is 3/2x + 15/2

Step-by-step explanation:
The slope of a line segment is −3/4 and the rise is known to be 21, find the run.
I’ll get you 16 point please someone answer.
Answers
Answer:
-28
Step-by-step explanation:
The big thing to remember here is
Slope=Rise/Run
We can put x for the run and get this equation
21/x=-3/4
From here it gets really easy. To find the value of x we can change -3/4 into 21/-28 because in this case we need a common numerator. 21/x=21/-28 and it is obvious that x=-28
Hope this helped let me know if you have questions.
An equilateral triangle has measurements as shown in the diagram. What is the area of the triangle?
Answers
Answer:
124.8
Step-by-step explanation:
The equation for the area of a triangle is base length (12) multiplied by the height length (10.4) divided by 2. Two of the same triangle create a rectangle, and by multiplying the base and the height you find this rectangle. To find the are of the triangle, you just need to remove the other triangle (divide by 2).

4s-28=4
Answers
Answer: s = 8
Step-by-step explanation:
Add 28 to both sides of the equation
4s - 28 + 28 = 4 + 28
Then simplify
4s = 32
Divide both sides of the equation by the same term
4s = 32
4s/4 = 32/4
Simplify again
s = 8
Solution
s = 8
