60 pts!!! HELP Find the inverse of the function f(x)= 4/9 x-4
show work
Answer:
Inverse Function: f^-1(x) = 9/4x + 9
Step-by-step explanation:
To find the inverse function we can interchange the position of the variables x and y, and then solve for y;
y = 4/9x - 4 => x = 4/9y - 4,
x = 4/9y - 4,
4/9y = x + 4,
y = 9/4x + 9/4(4),
y = 9/4x + 9/ f^-1(x) = 9/4x + 9
$10,000 down payment for your house if you can invest 2% of your monthly income (yearly income: $67,705) into an account that earns 4% quarterly. Also what is the formula for this? Is it compounded quarterly?
Answer:
the future value of each deposit = ($67,705 x 1/12 x 0.02) x (1 + 1%)ⁿ = $112.84 x 1.01ⁿ
where n = number of quarters (interest is compounded quarterly)
the effective interest = 1.01⁴ - 1 = 4.06%
Assuming that you are going to make monthly payments, then you would need the number of quarters (n) in order to determine the future value. Since the interest is compounded quarterly, each contribution = $112.84 x 3 = $338.52
For example, if you are planning to save money for 5 years (n = 5 x 4 = 20), then the future value of the investment = $338.52 x 22.019 (FV annuity factor, 1%, 20 periods) = $7,453.87
if you want to calculate the total number of contributions (n):
FV annuity factor, 1%, n? = future value / contribution = $10,000 / $338.52 = 29.5404
since you know the interest rate (1%) you have to look at a future value annuity table and search the n for 29.54. This is approximately 26 periods (FV annuity factor = 29.53).
4x + 9 = 2x + 15 .. I need help
Answer:
x = 3
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define Equation
4x + 9 = 2x + 15
Step 2: Solve for x
Subtract 2x on both sides: 2x + 9 = 15Subtract 9 on both sides: 2x = 6Divide 2 on both sides: x = 3Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 4(3) + 9 = 2(3) + 15Multiply: 12 + 9 = 6 + 15Add: 21 = 21Here we see that 21 does indeed equal 21.
∴ x = 3 is the solution to the equation.

Which of the following is true about similar figures?
All similar figures are congruent.
If two figures are not similar, they can still be congruent.
All congruent figures are similar.
If two figures are not congruent, they can't be similar.
Answer:
All congruent figures are similar
Step-by-step explanation:
Congruent means "same" in mathematics and you have evidence to prove it. You can look at two puppies with the exact same fur color and be like "yeah they're the same". If they are the same size and shape they're congruent. This is why the AAA postulate can't work because triangles can have the same angles yet be different sizes. If figures are not congruent, they can't be similar and figures that aren't similar can't be congruent either.
All similar figures are congruent is true about similar figures
What is congruency?We know two similar planer figures are congruent when we have sides or angles or both that are the same as the corresponding sides or angles or both.
In mathematics, congruent means identical, and you can cite examples to support your claim.
just by looking at them. They are congruent if their dimensions match. Triangles can have the same angles but differ in size, which makes the AAA postulate invalid.
If two figures are not similar, they cannot be congruent, therefore similarly unrelated figures cannot be congruent.

0.1 is the answer...............
The common difference [tex](d)[/tex] of Arithmetic Sequences [tex]4,4.1,4.2,4.3,4.4[/tex] is [tex]0.1[/tex] .
What is Arithmetic Sequence ?Arithmetic Sequence is also known as arithmetic progression and is a sequence of numbers in which the difference between the consecutive terms is constant.
What is common difference ?Common difference is the difference between two consecutive terms of an arithmetic progression.
We have arithmetic progression,

What is the solution to the linear equation 4b + 6 = 2 - b+ 4
Final Answer: [tex]b = 0[/tex]
Steps/Reasons/Explanation:
Question: What is the solution to the linear equation [tex]4b + 6 = 2 - b + 4[/tex]?
Step 1: Simplify [tex]2 - b + 4[/tex] to [tex]6 - b[/tex].
[tex]4b + 6 = 6 - b[/tex]
Step 2: Cancel [tex]6[/tex] on both sides.
[tex]4b = -b[/tex]
Step 3: Subtract [tex]-b[/tex] from both sides.
[tex]4b + b = 0[/tex]
Step 4: Simplify [tex]4b + b[/tex] to [tex]5b[/tex].
[tex]5b = 0[/tex]
Step 5: Divide both sides by [tex]5[/tex].
[tex]b = 0[/tex]
~I hope I helped you :)~
Answer:
b = 0
Step-by-step explanation:
(Combine like terms): 4b + 6 = 2 - b + 4
4b + 6 = 6 - b
(Use Addition property of
equality to add b): 4b + b + 6 = 6
5b + 6 = 6
(Use Subtraction property of
equality to subtract 6): 5b + 6 - 6 = 6 - 6
5b = 0
(Divide both sides by 5): 5b = 0

b = 01. ADEA has vertices D(8,4), E(2, 6), and F(3, 1). What are the vertices of the image after a dilation with a scale factor of 5 using the origin as the center of dilation? TO
Answer:
The vertices of the image are D' (40, 20), E' (10, 30), F' (15, 5)
Step-by-step explanation:
If the point (x, y) dilated by a scale factor k using the origin as a center of dilation, then its image is (kx, ky)
Let us use this rule to solve our question
∵ The vertices of ΔDEF are D (8, 4), E (2, 6), and F (3, 1)
∵ ΔDEF dilated by a scale factor 5
∴ k = 5
∵ The origin as the center of dilation
→ That means, multiply the coordinates of every point by 5
∴ D' = (8 × 5, 4 × 5)
∴ D' = (40, 20)
∴ E' = (2 × 5, 6 × 5)
∴ E' = (10, 30)
∴ F' = (3 × 5, 1 × 5)
∴ D' = (15, 5)
∴ The vertices of the image are D' (40, 20), E' (10, 30), F' (15, 5)

Which expression is equivalent to 4(9k+3)? A) 4(-7k+16k+3) B) 3(9k+4) C) 4(3k+9) D) 9(3k+4)
Answer:
Option A "4(-7k+16k+3)" would be the appropriate choice.
Step-by-step explanation:
On solving the equation, we get
⇒ [tex]4(-7k+16k+3)[/tex]
On applying BODMAS rule, we get
⇒ [tex]4(9k+3)[/tex]
Therefore,
⇒ [tex]4(9k+3)=4(-7k+16k+3)[/tex]
All other given options are not seems to be the equivalent of the given expression "4(9k+3)". So the above is the right approach.
The Blue whale presently the largest mammal is about to 2.27 times more than the largest dinosaur. Blue whales weigh about 1.362 x 10 to the fifth power kilograms. Using scientific notation, about how much did the largest dinosaur weigh?
Answer: 60,004.41 kilograms
Step-by-step explanation:
Given: Weight of Blue whales = [tex]1.362 \times 10^5[/tex] kilograms
= [tex]1.3621\times 100000=136210[/tex]
Weight of blue whale = 2.27 x (weight of largest dinosaur )
[tex]136210=2.27\times \text{(weight of largest dinosaur)}\\\\\Rightarrow\ \text{(weight of largest dinosaur)} =\dfrac{136210}{2.27}\\\\\Rightarrow\ \text{(weight of largest dinosaur)}=60004.41[/tex]
Hence, The weight of largest dinosaur = 60,004.41 kilograms
Maria takes 2 hours to plant 50 flower bulbs. Lois takes 3 hours to plant 45 flower bulbs. Working together, how long should it take them to plant 150 bulbs?
Answer:
Maria: (50 bulbs)/(2 hours) = 25 bulbs/hour
Lois: (45 bulbs)/(3 hours) = 15 bulbs/hour
Together: 25 + 15 = 40 bulbs/hour
(150 bulbs)/(40 bulbs per hour) = 3 3/4 hours
(3/4 hours)(60 minutes/hour) = 45 minutes
Total time: 3 hours 45 minutes
