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
Answer: A,B,D,E
Step-by-step explanation: All of them either have a base and height of 4, or if its E, it is 8 by2. The formula for solving a triangle is base x height divided by 2. In this case, the two sides have to equal 16, as the area is 16/2, or 8
Answer:
h = -5*t +800
Step-by-step explanation:
The initial value is 800 ft
She is falling at a rate of 5 ft per second
That would be -5ft/s
We can write this in the form
y = mx+b
h = -5*t +800 where t is the number of seconds and h is the height above ground
Solution:
f(x) = 2x + 3
g(x) = x - 9
f(x) + g(x)
= (2x + 3) + (x - 9)
= 2x + x + 3 - 9
= 3x - 6
