Answer:
<h2>c. (0, 0)</h2>
Step-by-step explanation:

Answer:
That can be re-written:
x^2 + 5x -8 = 0
We use the Quadratic Formula
a=1
b = 5
c = -8
x = [-b +- sq root (b^2 - 4ac) ] / 2a
x = [-5 +- sq root (25 - - 32)] / 2
x1 = [-5 + sq root (57)] / 2
x1 = 1.27491722
x2 = [-5 - sq root (57)] / 2
x2 = -6.2749172176

1)
a) 18/50
b) 6.1/3=2
c) 9/2.8/3=3.4=12
2)
1 1/2=1.2+1/2=3/2
3 3/4=3.4+3/4=15/4
if we can 12 muffins with 3/2 cups
how many muffins with 15/4
?.3/2=12.15/4
?=30 muffins
