Answer:
c = 0
Step-by-step explanation:
Step 1: Write equation
15 - 5(4c - 7) = 50
Step 2: Solve for c
Distribute -5: 15 - 20c + 35 = 50Combine like terms: -20c + 50 = 50Subtract 50 on both sides: -20c = 0Divide both sides by -20: c = 0Step 3: Check
Plug in c to verify it's a solution.
15 - 5(4(0) - 7) = 50
15 - 5(-7) = 50
15 + 35 = 50
50 = 50
15 - 20c + 35 = 50
50 - 20c = 50
-20c = 0
x = 0

This is the same as 9pi/2 or (9/2)pi
===================================================
Explanation:
A full circle has area
A = pi*r^2
Since the radius is r = 3, we know that
A = pi*r^2
A = pi*3^2
A = pi*9
A = 9pi
is the area of the full circle with radius 3.
But we have a semicircle here, so we need to cut this area in half
9pi/2 = (9/2)pi = 4.5pi
Answer:

Sofia wants to rent an apartment. She visits Apartment A which charges $100 for a one-time deposit and $400 per month for rent. She also visits Apartment B which charges $500 for a deposit, but only charges $350 per month in rent. Write and solve an inequality that shows how many months it would take for the total paid to be less for Apartment B.
Answers
Answer:
It takes 9 or more months for the Apartment B to pay less than Apartment A.
Step-by-step explanation:
Apartment B:
8 x 350 = $2800
$2800 + $500 = $3300
----------------------------------------------
9 x 350 = $3150
$3150 + $500 = $3650
Apartment A:
$400 x 8 = $3200
$3200 + $100 = $3300
----------------------------------------------
9 x 400 = 3600
3600 + 100 = 3700

What is the interest rate if...
Principal = $1,250
Time = 4 years
Interest = $285.
Answers
Answer:
The answer is 5.7 %Step-by-step explanation:
To find the rate given the principal , time and interest , we use the formula
[tex]r = \frac{100I}{pt} \\ [/tex]
where
p is the principal
t is the time
I is the interest
From the question
Principal = $1,250
Time = 4 years
Interest = $285
We have
[tex]r = \frac{285 \times 100}{4 \times 1250} = \frac{28500}{5000} = \frac{285}{50} \\ = 5.7[/tex]

What kind of sequence is this? arithmetic geometric both neither Submit
Answers
===============================================
Explanation:
The sequence 2,8,32,128,... is geometric
To get a new term, we multiply by the common ratio 4.
2*4 = 8
8*4 = 32
32*4 = 128
To find the common ratio, you pick any term you want, and divide by its previous term
r = (term2)/(term1) = 8/2 = 4
r = (term3)/(term2) = 32/8 = 4
r = (term4)/(term3) = 128/32 = 4
The starting term is a = 2, so the nth term is
a(n) = a*(r)^(n-1)
a(n) = 2*(4)^(n-1)

Step-by-step explanation:
Parallel lines have equal slopes.
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y - 5 = 4(x + 3) ← is in point- slope form
