Answer:
7
Step-by-step explanation:
(a^3 - b^3) / 5
Let a=2 and b = -3
Do the exponents inside the parentheses
(2^3 - (-3)^3) / 5
Then add
(8 - (-27))/5
Subtracting a negative is like adding
(8+27)/5
( 35)/5

Answer:
3 times the number of yards
Let f represents the number of feet
f = 3 * y
Step-by-step explanation:
Number of feet 3 6 9 12
number of yards 1 2 3 4
1*3 = 3
2*3 - 6
3*3 =9
4*3 = 12
number of feet is 3 times the number of yards
Let f represents the number of feet
and y represents the number of yards
number of feet is 3 times the number of yards
f = 3 * y
In most cases, the Card Act prevents credit card companies from raising the interest rate on an existing balance. In other words, if your rate goes up, the new rate will apply only to new charges going forward. But if you get hit with a penalty APR, your issuer is permitted to apply it to outstanding balances.
To figure this out, we just need to simplify as much as we can for each problem, and then find a common denominator.
A
4/6 = 9/12
2/3 = 3/4
this is false
B
4/6 < 9/12
2/3 < 3/4
8/12 < 9/12
this is true, but let's look at the others just in case
C
4/6 > 10/12
2/3 > 5/6
4/6 > 5/6
this is false
D
It looks like C and D are the same. This means D is also false.
So B is the only true statement

Answer:
C(-1, -4)
Step-by-step explanation:
We want ...
AC/CB = 1/5
5(C-A) = B-C . . . . multiply by 5CB
6C = B +5A . . . . . add 5A-C
C = (B +5A)/6 . . . divide by 6
C = ((4, 6) +5(-2,-6))/6 = (4-10,6-30)/6 = (-6, -24)/6
C = (-1, -4)
