Step-by-step explanation:
[tex]-4x-12<12[/tex]
[tex]-4x-12+12<12+12[/tex] (Add [tex]12[/tex] to both sides of the inequality to isolate [tex]x[/tex])
[tex]-4x<24[/tex] (Simplify)
[tex]\frac{-4x}{-4}<\frac{24}{-4}[/tex] (Divide both sides of the inequality by [tex]-4[/tex] to get rid of [tex]x[/tex]'s coefficient)

Which equation matches the graph?
Answers
Answer:
A.
Step-by-step explanation:
The Y-intercept is 3 so C and D are automatically are wrong because their Y intercept is 2.
The slope is 2x because you count the points that the line goes through.
For example: From (-1,1) count up and right until you get another point,
count using [tex]\frac{Rise}{Run}[/tex] the rise of this equation is 2 and the run is 1 so [tex]\frac{2}{1} = 2\\[/tex]
Rise = Vertical
Run = Horizontal
Because the slope is increasing the slope is positive meaning B is incorrect because it's slope is negative.
Hope this was clear and helped you out!
The equation that matches the graph is y = -2x + 3
A linear equation is in the form:
y = mx + b;
where y, x are variables, m is the slope of the line and b is the y intercept
The line passes through the point (0, 3) and (-1.5, 0). Hence:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-3=\frac{0-3}{1.5-0} (x-0)\\\\y=-2x+3[/tex]
The equation that matches the graph is y = -2x + 3

Which rule describes the composition of transformations that maps figure ABCDE to figure A" B" C" D" E"?
Answers
Answer:
It would be the fourth choice.
Step-by-step explanation:
To get ABCDE to A'B'C'D'E', you need to reflect the shape across line M. Then to go from A'B'C'D'E' to A''B''C''D''E'', you need to rotate about point C 180⁰.
It was first reflected across the x axis which would be line m. And since point c is the same place for the two bottom images , after the reflection it was rotated on point c.
The answer should be the 4th choice
A bag contains 21 coins consisting of nickles and dimes. The total value of the coins is $1.70.
Write a system of equations that models this situation. How many nickels are in the bag?
Answers
Answer:
8
Step-by-step explanation:
x = nickles
y = dimes
0.05x + 0.10y = 1.70
x + y = 21
y = 21 - x
0.05x + 0.10 (21 - x) = 1.70
0.05x - 0.10x + 2.10 = 1.70
-0.05x + 2.10 = 1.70
-0.05x = -0.40
x = 8

What is the mean of the data set?
47, 25, 43, 33
Answers
Answer:
The mean is 47
Step-by-step explanation:
First, you want to add up all of the numbers.
47 + 25 + 43 + 33 = 148
Now, you want to divide what you got by how many numbers there are.
148/4 = 37
The mean is 47
Mean of the terms given in the data set as {47, 25, 43, 33} (four terms) will be 37.
Calculations for the mean of a data set: Mean of the terms given in a data set is represented by the avarage of the terms.
Mean = [tex]\frac{\text{Total of the terms in a data set}}{\text{Numbers of the terms}}[/tex]
Total of the terms given in the the data set = 47 + 25 + 43 + 33
= 148
Number of terms in the data set = 4
Substitute these values in the expression of the mean,
Mean = [tex]\frac{148}{4}[/tex]
= 37
Therefore, mean of the data set given in the question is 37.

On a blueprint, the diagram of a building has a height of 25 cm.
The height of the building is x times the height of the diagram.
Which equation represents the height, h, of the building?
h = 25 : x
B
x = 25h
h = 25 + x
h = 25x
Answers
Answer:
h = 25x
Step-by-step explanation:
Given the following
height of building = h
height of diagram = 25cm
If the height of the building is x times the height of the diagram, then;
h = x * 25
h = 25x
Hence the required equation is h = 25x
