Solve the system of linear equations by graphing. y = –5/2 x – 7 x + 2y = 4 what is the solution to the system of linear equations?
a(–4.5, 4.25)
b(–1.7, –2.8)
c(0, –7)
d(3, 0.5)

Keywords

system; linear equations; graphing; solution

we have

-------> equation A

----> equation B

The system of linear equations is composed of equation A and equation B

Substitute the equation B in equation A

Find the value of x

The solution is the point

Using a graphing tool

see the attached figure

therefore

the answer is the option A

4sqrt5

step-by-step explanation:

the base has dimensions of 8 x 4, so the diagonal is 64 + 16 square rooted or 4sqrt5.

x = 3 ± √(5+y)
