Answer:
144
Step-by-step explanation:
plug in 5 where you see the x.
that gives us 9(4(5)-4)
multiply the 4 and the 5 first to get 9(20-4)
and by PEMDAS, we solve the parentheses first so now we have 9(16)
so now just multiply 9x16 to get 144
Step-by-step explanation:
9((4×5)-4)
9(20-4)
9(16)

What is 5-2(4a+1)+3a=13
Step-by-step explanation:
5-2(4a+1)+3a=13
5(4a+1)-2(4a+1)+3a=13
20a+5-8a-2+3a=13
20a-8a+3a+5-2=13

Ben wants to buy a new collar for each of his 5 dogs. The collars come in a choice of 9 different colors. Step 1 of 2 : How many selections of collars for the 5 dogs are possible if repetitions of colors are allowed
Answer:
59049 ways
Step-by-step explanation:
Given
[tex]Colors = 9[/tex]
[tex]Dogs = 5[/tex]
Required
Determine number of selection (repetition is allowed)
The number of collars is not given.
So, we'll assume that there are enough collars to go round.
If no repetition is allowed, each of the 5 dogs have 9 colours to select from.
i.e.
[tex]Dog\ 1 = 9[/tex]
[tex]Dog\ 2 = 9[/tex]
[tex]Dog\ 3 = 9[/tex]
[tex]Dog\ 4 = 9[/tex]
[tex]Dog\ 5 = 9[/tex]
So, the number of selection is:
[tex]Selection = 9 * 9 * 9 * 9 * 9[/tex]
[tex]Selection = 59049[/tex]

Carmen deposits $4000 into an account that pays simple interest at a rate of 3% per year. How much interest will she be paid in the first 3 years?
Answer:
$360
Step-by-step explanation:
I = Prt
I = 4000 * 3 * 3%
I = 12000 * 3% (Convert 9000 and 3% into fractions.)
I =12000/1 * 3/100 (100 and 12000 have a GCF of 100)
I = 120/1 * 3/1 (Disregard the over 1 portion.)
I = 120 * 3 (Multiply 120 by 3 to get 360.)
I = $360

Solve the following formula for the specified variable. B=1/4m(r+k) for r
Answer: r=4b/m-k
Step-by-step explanation: I think
The solution of the given formula B=1/4m(r + k) for r is r = 4(B/m) - k.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
More than one variable may be present inside a linear equation. An equation is said to be linear if the maximum power of the variable is consistently unity.
Given the expression,
B=1/4m(r+k)
4B = m(r + k)
r + k = 4B/m
r = 4(B/m) - k
Hence "The solution of the given formula B=1/4m(r + k) for r is r = 4(B/m) - k".

Olivia and Cody both have spinners with the color purple. Olivia determines that the probability of spinning purple on her spinner is 4 out of 12. Cody determines that the probability of spinning purple on his spinner is 3 out of 10. Which of the following statements is true?
The true statements:
A) Olivia's spinner has the highest probability of spinning purple.
What is the probability?The Probability in mathematics is the possibility of an event in time. In simple words, how many times that incident is happening in any given time interval.
Given:
Olivia and Cody both have spinners with the color purple.
Olivia determines that the probability of spinning purple on her spinner is 4 out of 12.
That means, 4/12 = 0.33
Cody determines that the probability of spinning purple on his spinner is 3 out of 10.
That means, 4/10 = 0.3
0.33 > 0.3
Therefore, Olivia's spinner has the highest probability of spinning purple.

what is the rule for the reflection
Answer:
(x,y) ---> (-x,y) 2nd choice
Step-by-step explanation:
reflection: If points reflect across the y-axis, their y-coordinates remain unchanged but their x-coordinates change into their opposites.
The original figure ABCD is reflected on y-axis and we got the image A'B'C'D'. Therefore, option B is the correct answer.
What is the reflection on y-axis?When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y).
In the given graph, ABCD is the original figure and A'B'C'D' is the image.
Here, A(-2, 1)→A'(2, 1)
B(-4, 1)→B'(4, 1)
C(-4, 5)→C'(4, 5)
D(-2, 4)→D'(2, 4)
Here, the rule is (x, y)→(-x, y)
Therefore, option B is the correct answer.

Which of the following did you include in your answer? Yes, the graph has been dilated. Using the standard form of the equation, substitute in the values: h = –2, k = 3, x = –1, and y = 0. Solve the equation to get a = –3. Graphically, the parent function follows the pattern of right 1, up 1. Moving 1 unit to the right from the vertex, you can move down 3 units to get to the point (–1, 0), so it has been horizontally compressed.

Answer and Step-by-step explanation:
The square root of 16 times x to the power of 6 times y to the power of 10 is the same as:
[tex]\sqrt{16x^{6} y^{10} } = \sqrt{16} * \sqrt{x^{6} } * \sqrt{y^{10} }[/tex]
The square root of 16 is 4.
The square root of x to the power of 6 is x to the power of 3.
The square root of y to the power of 10 is x to the power of 5.
So, the answer is:

shhssuuaBhsyegzvsysbNhsuehsgzgeysbs
Answer:
- 2
Step-by-step explanation:
so in order to solve this equation we are going to have to add x to each side of the equal sign to make the x a positive:
-6 - x = -4
+ x + x
making the equation look like this:
-6 = -4 + x
Now we are going to add 4 to each side of the equation to segregate our x:
-6 = -4 + x
+4 + 4
Making the equation look like this:
-2 = x
Now to check our work by placing -2 where x is in the equation -6 - x = -4:
-6 - x = -4 now -6 - (-2) = -4
Since the negative number is next to a subtraction sign -2 becomes positive 2
-6 + (2) = -4
We add them together and....:
-4 = -4
