For f(x) = 2x+1 and g(x) = 3x-7, find (f-g)(x)
Answer:
(f - g)(x) = -x + 8
General Formulas and Concepts:
Order of Operations: BPEMDASStep-by-step explanation:
Step 1: Define
f(x) = 2x + 1
g(x) = 3x - 7
(f - g)(x) = f(x) - g(x)
Step 2: Simplify
Set up: (f - g)(x) = (2x + 1) - (3x - 7)Distribute -1: (f - g)(x) = 2x + 1 - 3x + 7Combine like terms: (f - g)(x) = -x + 8♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

If $7,500 investment earns $450 over 3 years what's the interest rate
Answer:
Rate is 2%
Step-by-step explanation:
Step one:
given data
Principal= $7500
Simple interest= $450
time=3 years.
Applying the simple interest formula which is
SI=PRT/100
Step two:
substitute we have
450=7500*R*3/100
cross multiply we have
45000=22500R
divide both sides by 22500
R=45000/22500
R=2%

Answer:
Solve
Let's solve your inequality step-by-step.
10x−14>7x−8
Step 1: Subtract 7x from both sides.
10x−14−7x>7x−8−7x
3x−14>−8
Step 2: Add 14 to both sides.
3x−14+14>−8+14
3x>6
Step 3: Divide both sides by 3
3x/3>6/3
x>2

2. If r=7 is a solution to -6r+18=k(x-15), then which of the following must be the value of K?
(1)-8
(3)3
(2) -4
(4) 11
Answer: (1)-8
Step-by-step explanation: −6r+18=k(x−15)
Step 1: Flip the equation.
kx−15k=−6r+18
Step 2: Factor out variable k.
k(x−15)=−6r+18
Step 3: Divide both sides by x-15.
k(x−15)/x-15 =
−6r+18/x-15
k= −6r+18/x-15= -8

Answer:
Keywords:
Microscope, scale factor, enlargement, actual length, length to scale
For this case we have a microscope that shows an enlargement scale of objects, 140 times the actual size. Given the actual length of an insect, we want to know the scale length shown by the microscope. So, we have the following equation:
If the insect has a , then:
Thus, the microscope will show the insect with a size of 840mm
