X = pencils, y = pens
8x + 6y = 8.50
4x + 4y = 5.....multiply by -2
----------------
8x + 6y = 8.50
-8x - 8y = -10 (result of multiplying by -2)
-----------------add
-2y = - 1.50
y = -1.50 / -2
y = 0.75 <=== pens cost 0.75
4x + 4y = 5
4x + 4(0.75) = 5
4x + 3 = 5
4x = 5 - 3
4x = 2
x = 2/4
x = 0.50 <== pencils cost 0.50

Answer:
y = 2x -8
Step-by-step explanation:
The slope intercept form for a line is
y = mx+b where m is the slope and b is the y intercept
y = 2x -8
Answer:
x^2 +x+2
Step-by-step explanation:
f(x) = x^2+3
g(x) = x-1
f(x)+ g(x) = (f+g) (x)
x^2+3+ x-1
x^2 +x+2
