B²-4ac?
<span>5x²+7x-6 = 0 </span>
<span>the form is ax²+bx+c = 0 </span>
<span>a=5, b=7, c=-6 </span>
<span>The discriminant D = b²-4ac </span>
<span>= 7² - 4(5)(-6) = 49 + 120 </span>
<span>= 169 </span>
Answer:
B
Step-by-step explanation:
The answer is not A or D because they show a linear association
The answer is also not c because they show no correlation at all
The answer is B because it has a curve

Answer:
48 cups
Step-by-step explanation:
the first 2 cups of raisins goes into 12 cups of trail mix.
the next ones are as follows:
4 cups of raisins for 24 cups of trail mix
6 cups of raisins for 36 cups of trail mix
8 cups of raisins for 48 cups of trail mix
They both double each time a new bathc is made.
A = 4 - 5c
a = 4 - 5(-1/2)
a = 4 - (-2.5)
a = 4 + 2.5
a = 6.5
