Algebra question I don’t get it because you usually have to multiple A by C but there is no C in the problem.
Answers
And in this case, you are factorising in this question. You turn back into brackets basically.
We have:
72x^2 - 32
x^2 = x squared
factorising means finding the factor of.
(Forget the x squared for the moment to make life easier)
Factors of 72:
1 and 72
2 and 36
3 and 24
4 and 18
6 and 12
8 and 9
(9 and 8 = it repeats so we stop there)
And then factors of 32:
1 and 32
2 and 16
4 and 8
(8 and 4 = repeats so we stop there)
Notice how we see 8 twice in both factors of 72 and 32, this means that we use 8 as the main number we are going to multiply each of the 2 numbers in the brackets by. This is because it is the biggest common factor - this is what we have!
This is what we would have:
8(9-4)
BUT, that is not the answer!
Keep in mind we have the x squared too
But, 32 doesn’t have it?!!
It would be:
8(9x^2 - 4)
Do you get it??
Try to simplify it! Does it equal to 72x^2 - 32?

Select all equations that have graphs with the same y-intercept.
Select all that apply:
A) y = 3x - 8
B) y = 3x - 9
C) y = 3x + 8
D) y = 5x - 8
E) y = 2x - 8
F) y = (1/3)x - 8
Answers
Answer: A, C, D, E, and F have the same y-intercepts.
Step-by-step explanation:
The Equation for graph A has a y-intercept of -8
The Equation for graph B has a y=intercept of -9
The Equation for graph C has a y-intercept of -8
The Equation for graph D has a y-intercept of -8
The Equation for graph E has a y-intercept of -8
The Equation for graph F has a y-intercept of -8
The only difference between the y-intercepts of the equations is the equation for graph B, it has a y-intercept of -9 so it will not be the same as the other equations with the same y-intercepts. \
A, C, D, E, and F have the same y-intercepts.

Complete the following statement: The equation is (false, true) when x = 4, so 4 (is, is not) a solution.
Answers
Answer:
False, is not
Step-by-step explanation:
If we plug in 4 for x in the equation, we get that 5 * 4 + 3 = 12, and we can calculate that 20 + 3 = 12, which is not true. 4 is a false solution for that equation so it is not a solution (We can use this info to say that the answer is false, is not).

Answer:
96 1/4 in.³
Step-by-step explanation:
Convert 3 1/2 to 7/2, 5 to 5/1, and 11/2 stays the same.
Multiply 7/2 x 5/1 x 11/2 straight across to get 385/4.
Divide the numerator by the denominator, in this case it would be 385 divided by 4. Your answer should be 96 with a remainder of 1.
To convert this to a mixed number, 96 becomes your whole number and then the remainder (in this case 1) becomes the numerator and the divisor of the division problem (in this case 4) becomes the denominator. So now you have 96 1/4 in.³

Answers
Answer:
C. The charges of the atoms that make up a water molecule makes them attracted to other water particles
The correct option is water particles are attracted to other water particles.
What is cohesive force?The term "cohesive forces" is a generic term for the collective intermolecular forces responsible for the bulk property of liquids resisting separation.
Specifically, these attractive forces exist between molecules of the same substance.
Given that, the water is a very cohesive substance.
We know that, the cohesive substance attracts the molecules of same kinds,
Cohesion means the attraction of molecules for other molecules of the same kind, and water molecules have strong cohesive forces because of their ability to form hydrogen bonds with one another.
Therefore,
The charges of the atoms that make up a water molecule makes them attracted to other water particles.
Hence, the correct option is water particles are attracted to other water particles.

Which of the following best describes the data?
A. The data have range 2, and are otherwise unrelated.
B.The data are evenly distributed, with mean 7.1.
C.The data contain outliers, so the mean is not the best measure.
D.The data have no mode.
Answers
Answer:
A. The data has a range of 2.
Step-by-step explanation:
When you subtract 6 from 8 it's 2. Which is the range. Range is the smallest number subtracted from the biggest number.
The data does have a mode. The mode is the number or numbers that repeat more than once. Actually you have more than one mode so. D isn't right.
The data doesn't contain outliers. Outliers are numbers that don't range in with the rest. Meaning if you had the group of nunbers like 10, 10, 13, 54, 14, 12. 54 would be the outlier it isnt in range with the rest of the numbers.
Hope this helped!
The best description of the data set is "the data have range 2, and are otherwise unrelated", which is option A.
The given data set is as follows:
{7, 6, 8, 6, 8, 7, 8, 7, 8, 6}
The mean of the data set is :
(7+6+8+6+8+7+8+7+8+6)/10 = 7.2.
This means that on average, the boys are 7.2 years old.
The range of the data set is 8 - 6 = 2, which is relatively small.
This suggests that there are no extreme values in the data set.
Here, the value 8 occurs most frequently, so the mode is 8.
This means that 8 is the most common age among the boys.
Therefore, the best description of the data is option A.

What are inequalities ?
When two values are compared , an inequality represents whether one is greater than, less than, or not equal to the other.
It is given that the elevator can carry at most 2000 pounds of load. The weight of mover is 185 pounds. Also a mover is loading an elevator with many identical 48-pound boxes.
a)
Let's assume that the number of boxes is x.
Then the inequality can be written as :
48 × x + 185 ≤ 2000
Solving the inequality to get the value of x :
48x ≤ 2000 - 185
48x ≤ 1815
x ≤ 38 (approximate)

B. p ÷ 6.1 = 4.5
C. p ÷ 4.5 = 6.1
D. 4.5p = 6.1
Answers
Answer:
c.
Step-by-step explanation:
p/4.5 = 6.1
to isolate the variable do the opposite action
p/4.5 = 6.1
as p is divided by 4.5, you must multiply both sides by 4.5
p/4.5 ×4.5 = 6.1 × 4.5
