Solve for the other variable. (2 points: 1 point for the answer, 1 for showing the work)
4. Combine the two equations to eliminate one of the variables, and then solve for the other. (3 points: 1 for eliminating one variable, 1 for the answer, and 1 for showing your work)
Answer:
Step-by-step explanation:
The solution of the system is:
(x, y) = ( 5, 10)
We have the following system of equations:
12x + 6y = 120
4x + y = 30
Now, We have to solve by the method of elimination, we multiply the second equation by -3, then:
12x + 6y = 120___(1)
-12x - 3y = -90___(2)
Now, We add both the equations:
12x -12x + 6y - 3y = 120 -90
3y = 30
y = 10
We have to find the value of 'x":
4x + y = 340x + 10 = 30
4x = 30 - 10
x = 5
Thus, the solution of the system is:
(x, y) = ( 5, 10)

Answer:
[tex]x = y = 3\sqrt{ 2[/tex]
Step-by-step explanation:
Given
The attached triangle
Required
Find x and y
The given triangle has 45 degrees as one of its angles, and it is also a right angle triangle.
For this kind of parameter, the opposite = the adjacent
i.e. x = y
Apply Pythagoras theorem
[tex]x^2 + y^2= 6^2[/tex]
Substitute x for y
[tex]y^2 + y^2= 6^2[/tex]
[tex]2y^2= 36[/tex]
Divide by 2
[tex]y^2 = 18[/tex]
Take square root
[tex]y = \sqrt{18[/tex]
[tex]y = \sqrt{9 * 2[/tex]
Split
[tex]y = \sqrt{9} *\sqrt{ 2[/tex]
[tex]y = 3*\sqrt{ 2[/tex]
[tex]y = 3\sqrt{ 2[/tex]
[tex]x = y = 3\sqrt{ 2[/tex]

The water depth of a pond is initially 36 inches and decreases at a rate of 0.2 inches per day through evaporation. Write a linear function that represents the depth of the pond at a given time.
Answer:
36-0.2d
Step-by-step explanation:
d refers to the number of days
This should work for your question if not I'm very sorry
The required expression for the decreasing depth of the pond is y = 36 - 0.2x, Where y is the depth of the pond after x days.
The equation is the relationship between variables and constants represented as y = ax + b is an example of a polynomial equation.
Here,
The water depth of a pond is initially 36 inches
The water depth of a pond decreases at a rate of 0.2 inches per day through evaporation.
Let the number of the days be x , and the depth left be y
According to the question,
Total depth in x days = 0.2x
Total remaining depth = 36 - 0.2x
or
y = 36 - 0.2x
Thus, the required expression for the decreasing depth of the pond is y = 36 - 0.2x, Where y is the depth of the pond after x days.

Find the value of x.
Answer:
x = 1.8
Step-by-step explanation:
7x = 17x - 18
bring all x values to a side
7x -17x = -18
-10x = -18
divide by -10
x = 9/5 = 1.8
The value of x is 6.
We know from Mid point theorem
The Midpoint Theorem, also known as the Midsegment Theorem, states that in a triangle, the line segment connecting the midpoints of two sides is parallel to the third side and is half its length.
So, from the figure we can write
7x = 1/2 (17x - 18)
7x (2) = 17x - 18
14x = 17x - 18
By subtracting 17x from both sides to eliminate the x term on the right side:
14x - 17x = 17x - 17x - 18
-3x = -18
Next, divide both sides of the equation by -3 to solve for x:
(-3x) / -3 = (-18) / -3
x = 6

Answer:lol figure it out Step-by-step explanation:
A researcher wants to know how homeowners in her state feel about home warranties. She obtains a list of 879 homeowners in her state, selects 300 of them at random, and emails a questionnaire to them. 64 questionnaires are returned. Of these, 80% stated that they believe that the current home warranty coverage needs to be completely overhauled. Classify the following groups as the population or the sample for this particular study.
a. all homeowners in the researcher's state
b. The 879 homeowners whose names were obtained
c. The 64 homeowners who returned the questionnaire
d. The 80% who stated that the current home warranty coverage needs to be completely overhauled
Answer:
a. The population
b. The accessible population
c. The sample
d. The statistic
Step-by-step explanation:
a. All the homeowners in the researchers state = The target population
b. The 879 homeowners whose name were obtained = The sample frame (accessible population)
c. The 64 homeowners who returned the questionnaire = Research participants (the sample), the subjects
d. The 80% who stated that the current home warranty coverage needs to be completely overhauled = The statistic (subset or part of the sample)
5B. Using the balanced seesaw shown, find the ratio of lengths a/b in lowest terms.
Answer:
Lowest terms is 7:6
Step-by-step explanation:
A = 63
B = 54
Ratio is a:b = 63:54
63:54
Reduce 63 to lowest terms to get 7 by dividing 9.
63 ÷ 9 = 7
Reduce 54 to lowest terms to get 6 by dividing 9.
54 ÷ 9 = 6
So the reduced form 63:54 in ratio is 7:6.
7:6
I hope this helped!
Answer:
6:7
Step-by-step explanation:
weight * distance = weight * distance,
so 63 * d1 = 54 * d2
LCM(63,54) = 378
378÷63 = 6
378÷54 = 7
so the answer is 6:7

Answer:
The equation of the line is y=-1/2x-3.5
Step-by-step explanation:
Given the two points on the line, (1, -4) and (3, -5), find the slope of the line with the equation [tex]m=\frac{y2-x2}{y1-x1}[/tex].
[tex]m=\frac{-5-(-4)}{3-1} =\frac{-5+4}{3-1} =\frac{-1}{2}[/tex]
After you find the slope of the line, substitute x and y with either point given to you. For me, I'll use point (1, -4) to solve for the y-intercept.
[tex]-4=\frac{-1}{2} (1)+b[/tex]
[tex]\frac{1}{2} -4=\frac{-1}{2} +\frac{1}{2} +b[/tex] add both sides by 1/2 so that b is alone
[tex]\frac{-7}{2} =b[/tex]
You can rewrite -7/2 as -3.5.
Describe the shape of the data summarized in the histograms.
Answers:
5) Roughly symmetrical6) Skewed to the right (aka "right skewed" or "positively skewed")=======================================================
Explanation:
5) We don't have perfectly symmetrical data, as that would require the left half to be a perfect mirror copy of the right half. However, we have some semblance of symmetry going on. In the middle is 5 which is where the highest bar is, where the mode is located. The mean and median are likely to be around here as well. Then on either side of this highest peak are bars of shorter heights. The heights decrease as we move away from the center in either direction. We can draw an estimated or approximated bell curve (aka normal distribution curve or gaussian curve) to get a fairly good sense of how the data is roughly symmetric. The right-hand portion of this graph is shorter compared to the left side, but I don't think that's enough info to say if we have skewed data or not; so I would stick with "roughly symmetric" here.6) Unlike problem 5, we don't have symmetric data. Instead, we have data that is skewed to the right. The main cluster is grouped or centered on the left side, while we have some outliers to the right side. Draw a curve over each peak of the bars and you'll see that the right tail is pulled longer than the left tail is. We consider this a positively skewed distribution because there are outliers in the positive x direction compared to the main cluster. In contrast, a negatively skewed distribution would have outliers smaller than the main cluster. The mean is larger than the median for a right-skewed distribution. This is due to the mean being pulled on by the outlier, while the median is robust and isn't affected by outliers no matter how distant they are.
