Answer:
(g - f)(x) = 6x² - 5x - 2
General Formulas and Concepts:
Pre-Algebra
Distributive PropertyAlgebra I
Combining Like TermsStep-by-step explanation:
Step 1: Define
f(x) = x³ - x² + 5x
g(x) = x³ + 5x² - 2
(g - f)(x) is g(x) - f(x)
Step 2: Evaluate
Substitute: (g - f)(x) = x³ + 5x² - 2 - (x³ - x² + 5x)Distribute -1: (g - f)(x) = x³ + 5x² - 2 - x³ + x² - 5xCombine like terms: (g - f)(x) = 6x² - 5x - 2which equations are linear functions? select all that apply

An invested sum of $600000 to generate simple interest $3.9000 at 3 (whole number) 1/4% per annum if you don't know please don't answer
Answer:
20 years
Step-by-step explanation:
We can find the time it took to invest
Using the formula for calculating simple interest as shown
SI = PRT/100
Given
Principal P = $600,000
SI = $39,000
Rate R = 3 1/4%
Required
Time
Substitute
39,000 = 600,000*13/400 * T
39,000 * 400 = 600,000*13 * T
15,600,000 = 7,800,000T
T = 15,600,000/7,800,000
T = 20
Hence it took 20years for the sum invested to generate the interest

Find all real numbers x that satisfy the equation (x-4)(x-8) = 12.
Answer:
x=10
Step-by-step explanation:
(10-4)(10-8) = 12
(6)(2) =12
12 = 12
The required real number that satisfies the given expression is x=10, x= 2.
Given that,
To determined the real numbers x that satisfy the equation (x - 4)(x - 8) = 12
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
(x - 4)(x - 8) = 12
x²-12x+32=12
x²-12x+20=0
(x - 10)(x -2) = 0
Thus, the required real number that satisfies the given expression is x=10, x= 2.

Answer:
100 degrees
Step-by-step explanation:
The opposite angle will always be the same. since the opposite is 5a, then x = 5a. x is 5a, and 9a is 180 degrees so x=180(5/9), which is equal to 100 degrees.

An industrial engineer must estimate the cost of building a storage tank. The tank requires 208 sq ft of material at $9.29 per square foot. It also requires 4.5 hours of labor at $26.40 per hour plus 1.6 hours of labor at $19.60 per hour. Find the total cost of the tank.
Answer:
The total cost of making the tank equals $2,082.48
Step-by-step explanation:
Giving the following information:
The tank requires 208 sq ft of material at $9.29 per square foot.
It also requires 4.5 hours of labor at $26.40 per hour plus 1.6 hours of labor at $19.60 per hour.
To calculate the total cost, we need to multiply the unitary variable cost by the total amounts:
Direct material= 9.29*208= $1,932.32
Direct labor= 4.5*26.4 + 1.6*19.6= $150.16
The total cost of making the tank equals $2,082.48

Answer:
2b( 12 - 17a)
Step-by-step explanation:
This is the answer because:
1) Fator 2b out of 24b - 34ab:
2b x 12 = 24b = 24b ÷ 2b = 12
2b x 17a = 34ab = 34ab ÷ 2b = 17a
Therefore, the answer is 2b( 12 - 17a).

A variable needs to be eliminated to solve the system of equations below. Choose the
correct first step.
- 4x – 2y = 18
4x – 4y = -36
O Subtract to eliminate x.
O Subtract to eliminate y.
O Add to eliminate x.
O Add to eliminate y.
Step-by-step explanation:
-4x - 2y = 18
+ (4x - 4y = -36)
=> -6y = -18, y = 3
As we added the equations together, we have eliminated x and found y.
Hence the correct answer is "Add to eliminate x".
