Answer:
a= (Z + 2b)/24
Step-by-step explanation:
given:
Z = 24a - 2b
to solve for a, we will try to move "a" to one side of the equation and all other terms to the other side:
Z = 24a - 2b (add 2b to both sides)
Z + 2b = 24a -2b +2b
Z + 2b = 24a (switch sides)
24a = Z + 2b (divide both sides by 24)
a/24 = (Z + 2b)/24
a= (Z + 2b)/24

The intercept of a lineGiven the equation of a line expressed as:
y + 2 = 2(x+3)
We are to find the x-intercept of the line. The x-intercept occur at the point where y = 0
Substituting y = 0 into the equation will give;
y + 2 = 2(x+3)
0 + 2 = 2(x+3)
2 = 2x + 6

During the life of a $2500 loan, the interest paid is $318.75. If the interest rate is 8.5%, how long was the loan?
Answer:
1.5 years
Step-by-step explanation:
Simple Interest I = PRT
Principal = 2500, Rate R= 8.5%, SI = 318.75, T = ?
Now, substituting the above value
318.75 = 2500*0.085 * T
T = 318.75 / 2500*0.085 years
T = 318.75 / 2500*0.085 years
T = 318.75 / 212.5 years
T = 1.5 years

The time spent to travel a certain distance varies inversely as a car's speed. If it takes 5½ hours to travel a certain distance at 60 miles per hour, how long will it take to travel the same distance at 50 miles per hour?
Select one:
a. 6.6 h
b. 6.9 h
c. 4.6 h
d. 4.2 h
Answer:
6.6h
Step-by-step explanation:
So it takes 5.5 hours going at a speed of 60 miles per hour, multiply these two and we get a distance of 330 milesUse this distance to find the time if speed is 50 miles per hour, so time is derived by dividing the distance by the speed330 miles divide by 50 miles per hour gives 6.6 hoursBRAINLIEST!!!

The function f is continuous on the interval (0,9) and is twice differentiable except at x = 6, where the derivatives do not exist (DNE). Information about the first and second derivatives of f for some values of x in the interval (0,9) is given in the table above. Which of the following statements could be false?
Answer:
The statement that could be false is;
(C) The function has a relative minimum at x = 6
Step-by-step explanation:
The given parameters are;
The function is continuous in the interval 0 ≤ x ≤ 9
The function is not differentiable at x = 6
f prime (x) = Negative for 4 < x < 6, and positive for 6 < x < 8
Therefore, at x = 6, the function is vertical
The statement that could be false is that the function has a relative minimum at x = 6.
A continuous function f(x) does not have discontinuity at any point
The statement that could be false is (c). The function f has a relative minimum at x = 6.
The interval is given as:
Interval = (0,9)
From the question, we understand that the function is not differentiable at x = 6.
This means that the function may or may not have a relative minimum at x = 6.
Hence, the statement that could be false is (c).
