8 = x
Check:
you friend
70 - 5 x 8 = 30 | 54 - 3 x 8 = 30

Question 2
Austin needs a total of $350 to buy a new bicycle. He has $35 saved. He earns $15 each week delivering
newspapers. How many weeks will Austin have to deliver papers to have enough money to buy the bicycle?
Answer:
21 weeks
Step-by-step explanation:
Equation: y = 15x + 35
15 is the rate of change and 35 is the starting point
Lets replace y with 350 since that the goal
350 = 15x + 35
Subtract 35 from both sides;
315 = 15x
Divide both sides by 15;
x = 21
He will have to deliver papers for 21 weeks to have enough money to buy a new bicycle.
I need every answer and explanation. It’s constant rate of change.

Which is an x-intercept of the continuous function in the
table?
0 (-1,0)
(0, 6)
o(-6, 0)
0 (0, -1)
Answer:
(-1, 0), (2, 0), (3, 0)
Step-by-step explanation:
x-intercept of a line is defined by a point where y = 0.
So the point in the form of (x, 0) will be the x-intercept of the given continuous function.
From the table attached,
For x = -1, f(-1) = 0
For x = 2, f(2) = 0
For x = 3, f(3) = 0
Points (-1, 0), (2, 0) and (3, 0) are the x-intercepts of the continuous function f(x).

A mortgage company offers a loan for 30 years at an
annual rate that is equal to the prime rate published by
the Federal Reserve plus 2%. This can be modeled
using the function APR(P) = p + 0.02, where p is the
prime interest rate as a decimal. The annual interest
rate is then converted to a monthly interest rate using
the function (APR) =
APR
The Wilsons want to borrow

$128,000. Their monthly payments can be calculated
128,000r
by the function m(r) =
1-(1 + r)-360
Answer: C
Step-by-step explanation:
The Wilsons' monthly mortgage payment will be approximately $9,485.16.
How to get the Monthly Mortgage Payment?To calculate the monthly payments for the Wilsons' mortgage, we need to follow these steps:
Convert the annual interest rate to a monthly interest rate using the formula APR(P) = P + 0.02.
Plug the monthly interest rate into the formula m(r) = 128,000 * (r / (1 - (1 + r)⁽⁻³⁶⁰⁾)).
Let's perform the calculations:
Step 1: Convert the annual interest rate to a monthly interest rate
Let's assume the prime interest rate (P) published by the Federal Reserve is 4.5% (0.045 as a decimal).
APR(P) = P + 0.02
APR(0.045) = 0.045 + 0.02
APR(0.045) = 0.065 (monthly interest rate as a decimal)
Step 2: Calculate the monthly payments (m(r)) for a loan of $128,000 with the monthly interest rate (r) obtained from Step 1.
m(r) = 128,000 * (r / (1 - (1 + r)⁽⁻³⁶⁰⁾))
m(0.065) = 128,000 * (0.065 / (1 - (1 + 0.065)⁽⁻³⁶⁰⁾))
Now, let's calculate the monthly payments (m(r)):
m(0.065) = 128,000 * (0.065 / (1 - (1 + 0.065)⁽⁻³⁶⁰⁾))
m(0.065) = 128,000 * (0.065 / (1 - (1.065)⁽⁻³⁶⁰⁾))
m(0.065) = 128,000 * (0.065 / (1 - 0.124823)) (Approximately, (1.065)⁽⁻³⁶⁰⁾ ≈ 0.124823)
m(0.065) = 128,000 * (0.065 / 0.875177)
m(0.065) = 128,000 * 0.074285 (Approximately, 0.065 / 0.875177 ≈ 0.074285)
m(0.065) = 9,485.16
The Wilsons' monthly mortgage payment will be approximately $9,485.16.

Answer:
The radius of the hole is 0.42 feet
Step-by-step explanation:
Let us revise the rule of the volume of a cylinder
→ V = πr²h, where
→ V is the volume of the cylinder in a cubic unit
→ r is the radius of the base of the cylinder
→ h is the height of the cylinder
Let us solve our question
→ The volume of the cylinder is 3800 cubic feet
→ The height of the cylinder is 1.3 miles
Very Important Note: dimensions must have the same unit
→ Change the mile to feet
→ There are 5280 feet in 1 mile
→ Multiply 1.3 miles by 5280 to change it to feet
→ The height = 1.3 × 5280 = 6864 feet
Let us substitute the values of V and h in the rule above
∵ V = πr²h
∵ V = 3800 ft³
∵ h = 6864 ft
∴ 3800 = πr²(6864)
→ Divide both sides by 6864π to find r²
∴ r² = 0.1762205081
→ take √ for both sides to find r
∴ r = 0.4197862648
→ Round it to the nearest hundredth
∴ r = 0.42 ft
The radius of the hole is 0.42 feet
4(x + 3) = -8x solve this ?
Answer:
x = -1
Step-by-step explanation:
Step 1: Write equation
4(x + 3) = -8x
Step 2: Solve for x
Distribute 4: 4x + 12 = -8x
Add 8x on both sides: 12x + 12 = 0
Subtract 12 on both sides: 12x = -12
Divide both sides by 12: x = -1
Step 3: Check
Plug in x to verify if it's a solution.
4(-1 + 3) = -8(-1)
4(2) = 8
8 = 8
