Solve the system of equations below. Show or explain your work.

2x + y = 8
y = 5x -6

x=2, y=4

Step-by-step explanation:

2x+5x-6=8

7x-6=8

7x=14

x=2

y=5(2)-6

y=4

Step-by-step explanation:

2x+y=8

-2x+8: - x-8/2

m= -2

y=5x-6

5x-6: x+6/5

m=5

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
