c) How many applications will your mother actually use on her new cell phone? Solve the equation you wrote in part b to find the unknown variable.
Answers
Answer: x = 18 + 12
Step-by-step explanation:
Using the variable (x), you are able to give a number to any equation. By adding the 2 together, you end up with what (x) is going to be. Now solve for (x).
x = 18 + 12
x = 30
X=30

Stephen has $500 in an account for 9 months at a compound interest rate of 7.5%. At the end of 9 months, how much money is in his account?
Answers
Answer:
8.12
Step-by-step explanation:
Stephen has approximately $532.72 in his account at the end of 9 months with a 7.5% compound interest rate.
We can use the formula for compound interest to find the amount of money in Stephen's account at the end of 9 months:
A =P [tex](1 + r/n)^_(nt)[/tex]
where:
A is the amount of money in the account at the end of the period
P is the principal (initial amount) in the account
r is the annual interest rate (as a decimal)
n is the number of times the interest is compounded per year
t is the time (in years)
We know that P = $500, r = 0.075 (since the interest rate is 7.5%), n = 12 (since the interest is compounded monthly), and t = 9/12 (since 9 months is three-quarters of a year). Substituting these values into the formula, we get:
A = [tex]$500(1 + 0.075/12)^_{(12*(9/12))[/tex] = [tex]$532.72[/tex]
Therefore, Stephen has approximately $532.72 in his account at the end of 9 months.

Answer: I believe it is 508 cm²
Step-by-step explanation:
Start out by finding the surface area (SA) of the 2 shapes. The formula for SA is 2(wl + wh + wh).
Blue shape: 2(12x2 + 12x10 + 2x10) = 328 cm²
Red shape: 2(8x3 + 8x6 + 3x6) = 180 cm²
Now that the surface area of both shapes are solved, just add them together and you will get the answer of 508 cm²

Write the following expression in simplest form.
(6 + 12.5a) − (8 + 2.9a)
0.96a + (−14)
9.6a + (−2)
15.4a + (−2)
15.4a + (−14)
PLS HELP ME
Answers
Answer:
9.6a + (−2)
Step-by-step explanation:
To simplify the expression (6 + 12.5a) - (8 + 2.9a), you'll need to distribute the negative sign inside the parentheses and then combine like terms:
(6 + 12.5a) - (8 + 2.9a) = 6 + 12.5a - 8 - 2.9a
Now, combine the like terms:
(12.5a - 2.9a) + (6 - 8) = 9.6a - 2
So, the simplest form of the expression is 9.6a - 2.

Answer: It is below with explanations on how to do it! :D
Step-by-step explanation:
1. First one shows a graph and a line. Remember, the equation for this is y = mx + b. The point that crosses the y-axis is 0. So far, the equation looks like this: y = mx + 0. In order to find the slope, we have to choose another point on the graph. I will choose the point (-4, -2). The slope is the direction of the line travelling from left to right. So to get from (-4, -2) to the point 0, aka origin, we have to go up 2 units and move 4 units to the right. This method is called rise over run. Now the slope is 2 over 4 -> 2/4.
Final answer is y = 2/4x + 0
Simplified version is y = 1/2x + 0
That is your equation in slope intercept form!
2. The second one shows a graph and is asking to write an equation in slope-intercept form. Here is the equation for that -> y = mx+b
M is the slope, and b is the y-intercept (where the point crosses the line on the y-axis).
So, in this case, M=4 and b=0
Plug it into the equation, y = 4x + 0
The graph is attached below (I did not draw it but I took a screenshot from a video that shows it)
I also attached the graph for you for the last question!
