3x+5 = a
a * 6x = 18x^2 + 30x
R = 15x + 29
a * 5 = 15x + 25
R = 4
answer: 6x + 5; R = 4
Answer:the answer is D. 25:44
Step-by-step explanation: the first step is to do the cumulative total of Andrew's number of coins(100).
Then you do the cumulative total of Staci's coins(176).
After you find the cumulative total of them both, since it is Andrew:Staci, you will ratio Andrew's total to Staci's.
Which is 100:176 .
Then from here you reduce this to the lowest term
Answer:
f(-8) = 45
Step-by-step explanation:
Step 1: Define
f(x) = -6x - 3
x = -8
Step 2: Substitute and Evaluate
f(-8) = -6(-8) - 3
f(-8) = 48 - 3
f(-8) = 45
Answer:
At 1.5 seconds and 2.5 seconds
Step-by-step explanation:
Because this is parabolic motion, the object will reach the height of 68 feet when it's going up AND when it's coming down. In order to find out those times, you set the h on the left side of the equation equal to 68, because h stands for height.
Set that equal to 0 and factor to solve for t:
Using the quadratic formula, we get t = 1.5 and t = 2.5
