Answer:
y=9x-45
Step-by-step explanation:
Given:
We are given an equation of x and y. We need to solve for y.
It means to isolate variable y. We have to move all variable and constant right side and leave y at left side.
Subtract 9x both sides (Subtraction property of equality)
cancel like term
Divide each side by -1 (Division property of equality)
Hence, The equation solve for y=9x-45

{2, 8}
Step-by-step explanation:
We want to find x for ...
15 = 4|x -5| +3
12 = 4|x -5| . . . . subtract 3
3 = |x -5| . . . . . . divide by 4
±3 = x -5 . . . . . . show the meaning of absolute value
5 ±3 = x = {2, 8} . . . . . add 5
The values of x for which f(x) = 15 are 2 and 8.
Answer:
$1,179
Step-by-step explanation:
Lets use the compound interest formula provided to solve this:
<em>P = initial balance</em>
<em>r = interest rate (decimal)</em>
<em>n = number of times compounded annually</em>
<em>t = time</em>
<em />
First, lets change 2.6% into a decimal:
2.6% -> -> 0.026
Since the interest is compounded quarterly, we will use 4 for n. Lets plug in the values now:
The account balance after 10 years will be $1,179
