5x = 4y + 28

Mathematics
1 answer:
stich3 [128]2 years ago
6 0

Answer:

x = 36

Step-by-step explanation:

Rearrange the equations before solving simultaneously

4y = -5x - 28

2y = 7x - 24

now subtract

4y - 2y = 2y

5x - 7x = -2x

-28 - - 24 = -4

put these values together.

2y - 2x - 4.

2y = 2x + 4

y = 2x + 4 / 2

y = x + 2

substitute this into one of the 1st equations in the question.

5x = -4(x + 2) + 28

5x = -4x + 8 + 28

5x = -4x + 36

9x = 36

x = 4.

B is the midpoint

\\ \sf\longmapsto AB=\dfrac{1}{2}AC

\\ \sf\longmapsto 7x-3=\dfrac{5}{2}

\\ \sf\longmapsto 5=2(7x-3)

\\ \sf\longmapsto 5=14x-6

\\ \sf\longmapsto 14x=6+5

\\ \sf\longmapsto 14x=11

\\ \sf\longmapsto x=\dfrac{11}{14}

\\ \sf\longmapsto x=7.8

What is the value of y?<br><br> Enter your answer, as an exact value, in the box.
Amanda [17]
So for the 40-40-90 degree triangle, whenever the two legs are x values, then the hypotenuse is x value times the square root of 2.

--> a changed into a√2
√2 changed in √2 * √2
= 2

So the hypotenuse of the 40-40-90 degree triangle is 2.

Now for the 30-60-90 degree triangle, the smallest leg with the value of x is then changed to the value of x√3 if finding the longer leg.

-> a is changed to a√3
2 is changed into 2√3


So, y is 2√3 or approximately 3.46 units.
