Answer:
three solutions: {-3, -3, 0}
Step-by-step explanation:
This polynomial has already been factored, and the factors are x, x + 3 and x = +3. To solve this equation, set each of the factors equal to zero separately and solve each of the resulting equations:
x = 0 is a solution; the given equation equals zero when x = 0.
The next factor is x + 3; setting this equal to 0 yields the solution x = -3.
The last factor is x + 3; x = -3 is the third solution.
In summary, (x + 3)(x = 3) = 0 has two solutions; we call them "repeated roots." x(x + 3)(x = 3) = 0 has three solutions: {-3, -3, 0} of which two are "repeated."

If x is an integer, what is the least possible value for x that satisfies the inequality?
-5x - 12 < 33
A. -10
B. -9
C. -8
D. 9
E. 10
Answer:
C. -8
Step-by-step explanation:
We have to solve the inequality by isolating x.
-5x - 12 < 33
Add 12 to both sides.
-5x < 45
Divide both sides by -5 (remember to flip the sign when dividing by a negative).
x > -9
The least possible value for x that satisfies this inequality is -8.

Answer:
From -2<x<-1, the function F(X) is increasing. (B)
Really, it increases all from around -2.5<x<0.5
C is also the second answer, as it increases til around 2.5
It is decreasing from -4<x<-3. But increases right after. It then starts to slow down around x = 1 and go down again.
Which means (B) is your answer.
If you want to get fancy, its a polynomial and if you take the derivative for instantaneous rate, you will see f prime is increasing if you make an example function.

-2,5 < x < 1

I'm always forgetting how to do mean absolute deviation. Can someone remind me what the process is please?
Answer:
Take each number in the data set, subtract the mean, and take the absolute value. Then take the sum of the absolute values. Now compute the mean absolute deviation by dividing the sum above by the total number of values in the data set. Finally, round to the nearest tenth.

Does the graph represent a function?
Hey there!
No, the graph is not a function because it has two of the same inputs, (7, -6) and (7, -7).
It also can't be a linear function because the graphs are not pointed to form a straight line.
Hope this helps!
Have a great day!
Answer: No
Step-by-step explanation: Since we can draw a vertical line that passes through two points on the graph, the relation is not a function.

which numbers round to 40 when rounding to 10s?
Answer:
35, 36, 37, 38, 39, 41, 42, 43 and 44
Step-by-step explanation:
Everything above 5 rounds upwards, and all numvers below 5 rounds down. So 34 and down will be rounded to 30, and that's what happens with 44, 43, 42, and 41.

If h(x) = x2-5x + 7
find: h(2)
Answer:
h(2)= 1
Step-by-step explanation:
h(x) = x^2-5x+7
h(2) = 2^2-5*2+7
h(2)= 1
Answer:
1
Step-by-step explanation:
you have to substitute 2 were there's x in the function
h(2)=x^2-5x+7
=2^2-5(2)+7
=4-10+7
=1

Answer:
w=6
Step-by-step explanation:
First, we want to isolate the variable.
Add 6 on both sides
[tex]\frac{3w+5w}{2} =24[/tex]
Multiply both sides by 2.
3w+5w=48
Combine like terms.
8w=48
Divide both sides by 8.
w=6

Find the area of the figure in the image attached. Round to the nearest tenth if necessary.
Answer:
The area of the figure shown is 37.5cm^2, or 37 1/2cm^2, depending on what it wants from you.
Step-by-step explanation:
Break the shape into a triangle with measurements of 2.5, and 6.
And then the Rectangle with measurements of 6, and 5.
area of a rectangle is w*l so 6*5=30in
Area of a triangle is b*h*1/2 or b*h divided by 2 (either way both are the same, chose what makes you comfortable, I will use the first one.),
2.5*6*1/2
2.5*6=15
15*1/2=7 1/2cm or as a decimal 7.5cm
Now add the two for the full area, 30+7.5=37.5cm

Answer:
I believe the answer to your question is 38.
Step-by-step explanation:
Here is what I did: First, I found the radius, and to do that, I did 12 divided by 2, which gave me 6. then I did 6 divided by 2, to find the radius, of the radius I just found. which gave me 3, then I did 3 times 12, which gave me 36, so the answer should be 38 :)

Hey guys so I have a question. How do you determine the appropriate center of measure? I know that you have to find the mean median and mode but once you find the mean median and mode, how do you determine the center of measure? I'm confused.
Answer:
The two most widely used measures of the “center” of the data are the mean (average) and the median. To calculate the mean weight of 50 people, add the 50 weights together and divide by 50 . To find the median weight of the 50 people, order the data and find the number that splits the data into two equal parts.
Steve buys a wallet that costs $35.00. He pays 10% sales tax. How much does he pay for the wallet with tax?
A. $48.50
B. $38.50
C. $18.50
D. $45.50
Answer:
B. $38.50
Step-by-step explanation:
The original price of item (before tax) is 100% of the price of the item since 100% means the whole amount.
The tax is 10% of the original price, so add 10% to 100% making it 110%.
The total price including tax is 110% of the original price.
We need to find 110% of $35.00.
To find a percent of a number, multiply the percent by the number.
110% of $35.00 = 110% * $35.00
Change the percent to a decimal by moving the decimal point two places to the left.
110% becomes 1.10 as a decimal
110% of $35.00 = 110% * $35.00 = 1.10 * $35.00 = $38.50
Answer: B. $38.50
