Given:
The equation is:
[tex]8x^3=(-2x)A[/tex]
To find:
The missing factor AAA that makes the equality true.
Solution:
We have,
[tex]8x^3=(-2x)A[/tex]
Divide both sides by -2x to isolate A.
[tex]\dfrac{8x^3}{-2x}=A[/tex]
[tex]-4x^2=A[/tex]
Therefore, the value of A is [tex]-4x^2[/tex].

Answer:
119
Step-by-step explanation:
151 is the outside of the angle so you do 180-151 which is 29 and that plus 32 which is 61 and then 180-61 which is 119
Answer:
x = 119°
Step-by-step explanation:
180° - 151° = 29°
so now we have two angles: 29° and 32°.
32° + 29° + x = 180°
61° + x = 180°
x = 119°
Find the intersection points of the parabola y=−3x2−2x+2 and the line 10x−y=−11. Give your answer as two ordered pairs separated by a comma. For example, if you found that the solutions were (1,2) and (3,4) you would enter (1,2),(3,4).
Answer:
(-1,1),(-3,-19)
Step-by-step explanation:
y=−3x²−2x+2 (1)
10x−y=−11
y=10x+11 (2)
−3x²−2x+2 = 10x+11
3x² + 12x + 9 = 0
x² + 4x + 3 = 0
(x + 1)(x+3) = 0
x= -1 or x = -3
y = 1 or y = -19
The solutions of the equations y = −3x² − 2x + 2 and 10x − y = −11 will be (-1, 1) and (-3, -19).
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The equations are given below.
y = −3x² − 2x + 2 ...1
10x − y = −11 ...2
From equations 1 and 2, then we have
10x + 11 = −3x² − 2x + 2
3x² + 12x + 9 = 0
x² + 4x + 3 = 0
x² + 3x + x + 3 = 0
x(x + 3) + 1(x + 3) = 0
(x + 3)(x + 1) = 0
x = -1, -3
The value of y at x = - 1 is given as,
y = 10(-1) + 11
y = 1
The value of y at x = -3 is given as,
y = 10(-3) + 11
y = - 19
The solutions of the equations y = −3x² − 2x + 2 and 10x − y = −11 will be (-1, 1) and (-3, -19).

Heather and Alyssa are saving money for summer break. Heather currently has $50 in her savings account and she will save $25 per week until summer break. Alyssa currently has $200 in her savings account and she will save $10 per week. They want to know when they will have the same amount of money in their bank accounts. Which system of equations represents this situation?

Contract the back of the throat and breathe deeply through your mouth.
Inhale and exhale completely while relaxing the shoulders.
When the yawn comes “reach and extend into it” to stretch the jaw muscles.
Step-by-step explanation:
Answer:
10 weeks, Substituion Equation.
Step-by-step explanation:
(Assume that x= 'per week').
We can write this as 50 + 25x=y for Heather's savings, &
200 + 10x=y for Alssa's savings.
We can combine these equations to make 200 +10x= 50+25x, because we know 50+25x=y, like we found out in the first equation. We can now subtract 25x from each side, and subtarct 200 from each side, to get
10x - 25x = 50 - 200, which can be simplified to -15x=-150. If we divided each side by -15, we get 10. Therefore, it will take 10 weeks for them to have the same amount of money. I think this is the Substituaion Equation

Thirty adults were asked how many pets they have had over their lifetime. The results are shown in the histogram below.
A bar graph entitled Lifetime Pets has number of pets on the x-axis and number of adults on the y-axis. 14 adults had 1-5 pets; 9 had 6 to 10; 5 had 11 to 15; 2 had 16 to 20.
Which of the following is most likely true?
The true statement about the number of pets owned by the thirty adults is (b) The mean and median are both in the interval 6-10
What is an histogram?Histograms are graphs that are used to represent data, where the length of the bars represent the frequency
The data on the histogram are:
14 adults = 1-5 pets;
9 adults = 6 to 10 pets;
5 adults = 11 to 15 pets
2 adults = 16 to 20 pets
The mean is calculated as:
[tex]\bar x = \frac{\sum fx}{\sum f}[/tex]
So, we have:
[tex]\bar x = \frac{14 * 3 + 9 * 8 + 5 * 13 + 2 * 18}{30}[/tex]
This gives
[tex]\bar x = 7.2[/tex]
7.2 is in interval 6 to 10
The median is:
[tex]Median = \frac n2[/tex]
[tex]Median = \frac {30}2[/tex]
[tex]Median = 15th[/tex]
The 15th element is also interval 6 to 10
Hence, the true statement is (b) The mean and median are both in the interval 6-10

Step-by-step explanation:
Hey There!
So if you didn't know all of the angles in a triangle add up to equal 180
so to find the missing angle we subtract the given angles from 180
180-90-54=36
therefore the missing angles is 36
Answer:
36
Step-by-step explanation:
180 degrees in a triangle
that little square means its a right angle therefore it is 90 degrees
90+54=144

The highway mileage (mpg) for a sample of 8 different models of a car company can be found below. Find
the mean, median, mode, and standard deviation. Round to one decimal place as needed.
20, 22, 26, 27, 30, 31, 35, 35
Mean =
Median =
Mode =
Standard Deviation =
Mean = 28.3 , Median = 28.5, Mode = 35, Standard deviation = 5.2
(All of the above are rounded off to one decimal place)
How to find mean, median, mode ?
The given data are : 20, 22, 26, 27, 30, 31, 35, 35
We know that, mean = (sum of samples)/(no. of samples)
= (20+22+26+27+30+31+35+35)/8
= 226/8 = 28.25 = 28.3 (approx)
Here, median = (sum of 4th & 5th sample)/2
= (27+30)/2 = 57/2 = 28.5
Since 35 appears highest number of times, i.e. 2 times, then we can say that mode is equals to 35
What is the required standard deviation ?Standard deviation = √{(20-28.3)²+(22-28.3)²+(26-28.3)²+(27-28.3)²+(30-28.3)²+(31-28.3)²+(35-28.3)²+(35-28.3)²}/8
= √{68.89+39.69+5.29+1.69+2.89+7.29+44.89+44.89}/8
= √(215.52/8) = √(26.94) = 5.190 = 5.2 (approx)

-12 -24 which one is greater or less than
Answer:
-12 > -24
Step-by-step explanation:
When the numbers are negative the number that is closer to zero is the greatest
Answer:
-12 is greater than -24 or -12 > -24Step-by-step explanation:
Think of a number line, 0 being the middle point separating positive numbers on the right, and negative numbers on the left. The farther left you go down the number line, the smaller the numbers get in value.
With -12 being closer to 0, and -24 being farther down, which makes -24's value decrease. Which therefore makes it smaller.
