Answer:
<em>none of the expressions shown is correct</em>
The appropriate expression is ...
90,000(1+0.006)^72+708.61[(1-(1+0.006)^72)/0.006] . . . best matches C
Step-by-step explanation:
The formula used to calculate the remaining balance is ...
A = P(1 +r)^n +p((1 -(1 +r)^n)/r) . . . . . note the parentheses on the fraction numerator
In this formula, r is the monthly interest rate: 7.2%/12 = 0.006, and n is the number of monthly payments: 6×12 = 72. Putting these values into the formula along with the loan amount (P=90,000) and the payment amount (p=708.61) gives ...
A = 90,000(1.006)^72 +708.61((1 -(1.006)^72)/0.006)
A = 74,871.52
We are given equation V = r²h.
Let us break it into parts to get the correct variation.
V = r²h could be written first V= r² × h.
And we could break it in two different proportions:
V ∝ r² can be read as V is directly proportional to r².
V ∝ h can be read as V is directly proportional to h .
Non of the variable r² or h in denominator.
<em>When we have any variable in denominator, it's an inverse variation and if we don't have any variable in denominator, it would be a direct variation.</em>
<h3>Therefore, we can say V = r²h is a direct variation.</h3>
Answer:
2.48$
Step-by-step explanation:
You can say that the tip is ? of of 13.75 and written as
and .18 is cross multiply these so
13.75 x 18 = 100?
247.5 = 100?
2.475 = ?
then round up
You have 19 state quarters, which is 1/3 of all your quarters. So, you have 57 quarters total. 1/4,or 5, of your dollars are tyler dollars, meaning you have 20 dollar coins total. So:
57(.25)+20(1)=????

A) Substitution
substitute y = 5x-2 for y in the first equation and solve for x:
5x-2 = 7x-8 subtract 7x from both sides
-2x-2 = -8 now add 2 to both sides
-2x = -8 + 2 simplify
-2x = -6 divide both sides by -2
x=3
Now substitute x with 3 in either equation
y=5x-2 =5*3-2 =13
(3,13)
B) (3,13) is the point where the two lines intersect
y=mx+b is the equation of a line
