Answer:
She could purchase from stores A, D and E.
Step-by-step explanation:
She needs 8 cups so I multiplied each price by 8;
Store A 0.49(8)=$3.92
Store B 0.51(8)=$4.08
Store C 0.55(8)=$4.40
Store D 0.48(8)=$3.84
Store E 0.45(8)=$3.60
For a perfect square
b² = 4*a*c
Comparing ax² + bx + c = 0 to x² + bx + 16
a = 1, c = 16
<span>b² = 4*a*c
</span>
<span>b² = 4*1*16
</span>
<span>b² = 64
</span>
b = √64
b = 8
The value of b = 8.
Answer:
no it doesnt a Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. . so this is not one because its needs to be straight that is a Non linear function.
Step-by-step explanation:
Area of triangle = base x height /2
48 = (a+14)a/2
a^2 +14a = 96
a^2 + 14a - 96 = 0
Solving for a = 5.04
2 + 4(3+2x) = 3x + 8
2 + 12 + 8x = 3x + 8
14 - 8 = 3x - 8x
6 = -5x
x = -6/5
