Based on the given situation above and given that the Cost is C and x is for the credit hours taken, and that per hour is $160 with an additional $50 to it, the equation would be like this: C(x) = 160x + 50. So the correct answer would be option C.
Answer:
The rate of change in the submarine's elevation is 26.0 feet per second.
Step-by-step explanation:
She begins 151 feet below sea level
Thus, her initial point is y₁ = 151 feet below sea level
i.e. at t₁=0 seconds, y₁ = 151 feet below sea level
After descending for the 3 seconds, she is 229 feet below sea level.
Thus, her second point is y₂ = 229 feet below sea level after 3 seconds
i.e. at t₂=3 seconds, y₂ = 229 feet below sea level
The rate of change is basically the slope. Thus, the rate of change can be obtained by taking the slope.
slope = rate of change = (y₂ - y₁)/(t₂ - t₁)
= (229 - 151) / (3 - 0)
= 78/3
= 26.0
Therefore, the rate of change in the submarine's elevation is 26.0 feet per second.
3x-9 would equal 3(x-3) because you factor the 3 out of the 9.
Answer: Hope this helps
Step-by-step explanation:
6.39 = 639
100
= 639
100
as a fraction
To convert the decimal 6.39 to a fraction, just follow these steps:
Step 1: Write down the number as a fraction of one:
6.39 = 6.39
1
Step 2: Multiply both top and bottom by 10 for every number after the decimal point:
As we have 2 numbers after the decimal point, we multiply both numerator and denominator by 100. So,
6.39
1
= (6.39 × 100)
(1 × 100)
= 639
100
.
(This fraction is alread reduced, We can't reduce it any further).
As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 639
100
is also equal to 639
100
when expressed as a mixed number
X intercept is 40. it’s where the line crosses the c axis.
