Answer:
1. 48a/24a³b²; domain {a ≠ 0 and b ≠ 0} 2. 15b³/24a³b² ; domain {a ≠ 0 and b ≠ 0}
Step-by-step explanation:
1. To have a denominator 24a³b², we multiply 2/a²b² by 24a/24a.
So, 2/a²b² × 24a/24a = 48a/24a³b². For this expression to the valid, the domain is a ≠ 0 and b ≠ 0
2. To have a denominator 24a³b², we multiply 5b/8a³ by 3b²/3b².
So, 5b/8a³ × 3b²/3b². = 15b³/24a³b². For this expression to the valid, the domain is a ≠ 0 and b ≠ 0

12(−1.4m+0.4)=
0.7m + 0.2
-0.7m + 0.2
2.8m + 0.8
-2.8m + 0.8
Answer:
m = 0.28571428571
or 0.29(to the nearest tenth)
Step-by-step explanation:
First, distribute
12(−1.4m+0.4)=
-16.8m + 4.8 =
Now move the constant to the right.
-16.8m + 4.8 =
-16.8m = -4.8 =
Now divide,
-16.8m = -4.8 =
m = 0.28 or 0.29

Answer:
Since I don't have the numbers to plot, I'll tell you where to begin
Step-by-step explanation:
When plotting temperatures, it's important to remember positives and negatives
It's always a good idea to start by marking the halfway point as zero
Then, if the numbers are in the tens, make each increment an increasing value of ten/-ten in each direction.
If they're low, (in the ones digits) then just mark the numbers on the increments in the positive/negative directions

Answer:
[tex]\displaystyle n^3-\frac{1}{n^{2}}[/tex]
Step-by-step explanation:
Exponents Properties
We need to recall the following properties of exponents:
[tex](a^x)^y=(a^y)^x=a^{xy}[/tex]
[tex]\displaystyle a^{-x}=\frac{1}{a^x}[/tex]
We are given the expression:
[tex]2^m=n[/tex]
We need to express the following expression in terms of n.
[tex]8^m-4^{-m}[/tex]
It's necessary to modify the expression to use the given equivalence.
Recall [tex]8=2^3 \text{ and }4 = 2^2[/tex]. Thus:
[tex](2^3)^m-(2^2)^{-m}[/tex]
Applying the property:
[tex](2^m)^3-(2^m)^{-2}[/tex]
Substituting the given expression:
[tex]n^3-n^{-2}[/tex]
Or, equivalently:
[tex]\mathbf{\displaystyle 8^m-4^{-m}= n^3-\frac{1}{n^{2}}}[/tex]

Do you think it is easy to determine the solution set of a system of linear equations by graphing? Explain your answer.
Answer:
Yes, if you keep all of this in mind... This all came from my lesson during class btw.
Step-by-step explanation:
Each shows two lines that make up a system of equations. If the graphs of the equations intersect, then there is one solution that is true for both equations. If the graphs of the equations do not intersect. Almost any situation where there is an unknown quantity can be represented by a linear equation, like figuring out income over time, calculating mileage rates, or predicting profit. Many people use linear equations every day, even if they do the calculations in their head without drawing a line graph. When both equations have the same slope, but not the same y-intercept, they'll be parallel to each other and no intersections means no solutions. When both equations have different slopes than regardless of the y-intercept they'll intersect for certain, therefore it has exactly one solution. The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect.
On a coordinate plane, 2 rectangles are shown. Rectangle A B C D has points (negative 10, 8), (negative 4, 8), (negative 4, 4), (negative 10, 4). Rectangle W X Y Z has points (4, negative 4), (7, negative 4), (7, negative 12), (4, negative 12). Are rectangles ABCD and WXYZ congruent? Why or why not? Yes, all right angles were preserved. Yes, both rectangles have an area of 24 square units. Yes, a 180° rotation about the origin will map ABCD to WXYZ. No, there is not a rigid transformation or a combination of rigid transformations that will map ABCD to WXYZ.
Answer:

What is the constant of proportionality for the question (-4x + 8y = 0)?
Answer: 1/2
Step-by-step explanation:
1) Put the equation into y=kx form
- add 4x to both sides
- divide by 8 on both sides to get y=1/2x
2) k is the constant of proportionality

Find the value of c that completes the square
x^2-16x+c
Please help me with how to do this, and show me. Thank you.
Answer:
c = 64
Step-by-step explanation:
Given
x² - 16x + c
To complete the square
add ( half the coefficient of the x- term )² to x² - 16x
x² + 2(- 8)x + 64
= (x - 8)²
Thus
x² - 16x + 64 = (x - 8)² ← a perfect square
with c = 64

Marcel reads 20 pages every other day Xion reads 8 pages every day Amber reads 56 pages every 7 days Francessca reads 55 pages every 5 days Which one of these will get to 350 pages first? State the number of days they will take to complete it.
Answer:
Marcel reads 20 pages every 2 days.
Then, in one day, she reads:
20/2 = 10 pages per day.
Now, we know that in one day she reads 10 pages, then we can subdivide the number 350 in N groups of 10 pages, each one of these N groups needs one day to be read, then 350 pages will be read in N days:
N = 350/10 = 35 days.
Xion reads 8 pages per day.
Then to read 350 pages, he neds:
N = 350/8 = 43.75 days
Amber reads 56 pages in 7 days.
Then she reads 56/7 = 8 pages per day (Same as Xion)
Then she also needs 43.75 days to read 350 pages.
Francessca reads 55 pages in 5 days.
Then she reads 55/5 = 11 pages per day.
To read 350 pages, she needs:
350/11 = 31.82 days
Then the one that needs less days to read 350 pages is Francessca.
What operation must be used on the exponents in order to simplify the expression? (x^3)^7
Answer: So the trick I was taught to use was PEMDAS which stands for Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction. You solve the parenthesis first, followed by exponents if there are any. Multiplication and division are equal. So if there's multiplication and division in the problem, you solve the one closest to the left or start of the equation first. The same rules apply for addition and subtraction. They are both equal so you solve the first one first, even if the subtraction is before the addition.
