Two times x is 8 more than y. The sum of x and two times y is 14. Write two equations and graph to find the value of y.
y = 6
y = 4
y = -4
y = -6

Option B: is the value of y

Explanation:

It is given that "Two times x is 8 more than y". Writing it as expression, we have,

It is also given that "The sum of x and two times y is 14". Writing it as expression, we have,

To find the value of y, let us solve the two equations using substitution method.

From the equation , let us find the value of x.

Now, substituting in the equation , we get,

Thus, the value of y is

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

the answer is 31.27mph
