Describe and correct the error a student made when graphing the linear equation y = - 6.
Answers
Answer:
The error is in computing the y intercept. It should be at (0, -6) not (0, 6)
Step-by-step explanation:
The equation of the line is
[tex]-\frac{3}{4} x - 6[/tex]
y intercept is at point x = 0
When x = 0,
[tex]y = -\frac{3}{4} x - 6\\\\y = 0 - 6 \\\\y = -6[/tex]
So y intercept is at point (0, -6)
If we plot a second point 3 units down and 4 units right we should get the point 0 + 4, -6 - 3) = (4, -9)
Plugging this into the original correct equation satisfies the equation
[tex]y = -\frac{3}{4} x - 6\\\\y = -\frac{3}{4} (4) - 6 \\\\y = -3 -6 = -9 \\\\[/tex]
So we can see that the line does pass through (4, -9)
See attached graph for further clarification

Which expression represents the sequence of operations described below?
subtract 4 from 8, then multiply the result by 5
Answers
Answer:
5(8-4)
Step-by-step explanation:
You need to do the subtraction first, so put it in parenthesis because otherwise subtraction comes after multiplication if you follow PEMDAS, then put a five outside to multiply it by the difference of 8 and 4.
Answer: 5 x (4-8) or 5(4-8)
Step-by-step explanation:
First, put 4-8 in brackets, because you need to do it first and without brackets you would do the multiplication first (because of BEDMAS). Then, you would multiply your subtraction by 5.

A company manufactures cell phone cases. The length of a certain case must be within 0.25 mm of 125 mm, as shown (figure is not to scale). All cases with lengths outside of this range are removed from the inventory. How could you use an absolute value inequality to represent the lengths of all the cases that should be removed? Explain.
Answers
Answer:
Step-by-step explanation:
the length must be within plus or minus .25 mm of 125 mm.
if x is the length of the case, then:
absolute value of (x - 125) must be <= .25
this is shown as |x - 125| <= .25
when the expression within the absolute value sign is positive, the expression becomes (x - 125) <= .25
add 125 to both sides of this inequality to get:
x <= 125 + .25 = 125.25
when the expression within the asbolute value sign is negative, the expression becomes (x - 125) >= -.25
add 125 to both sides of this inequality to get:
x >= 125 - .25 = 124.75
the manufactured case must have a length that is greater than or equal to 124.75 mm and less than or equal to 125.25 mm.
otherwise it is removed from the inventory.
It appearxs that the other tutor talked a lot about your question; but he did not answer it.

Step-by-step explanation:
To find the mean you need to add up all the values and then divide it by the number of values there are so:
20 + 20 + 13 + 14 + 18 = 85
Then divide it by 5 because there are 5 values:
85 / 5 = 17

find the area and circumference of each circle. Use pi in your answer (example: radius = 8, or diameter = 14).
Answers
Answer:
Solutions below.
Step-by-step explanation:
First, we have to define each of the formulas first.
Area of Circle =
[tex]\pi {r}^{2} [/tex]
Circumference of Circle =
[tex]2\pi \: r[/tex]
With the above formula above, we can find the Area and Circumference for each circle.
Circle A:
Radius = 8
Area =
[tex]\pi {(8)}^{2} = 64\pi {units}^{2} [/tex]
Circumference =
[tex]2\pi(8) = 16\pi \: units[/tex]
Circle B:
Diameter = 14 units
Radius = 14 ÷ 2 = 7 units
Area =
[tex]\pi {(7)}^{2} = 49\pi {units}^{2} [/tex]
Circumference =
[tex]2\pi(7) = 14\pi \: units[/tex]
Circumference: 50.26
Area: 153.93
Circumference: 43.98

the drawing at the right is a plan for an apartment. The length of each Square on the grid represents 1 cm. The scale from the apartment to the drawing is 8 ft to 1 cm long. Draw another scale drawing of the apartment using a scale from the apartment to the drawing of 4 ft to 1 cm. Justify why you're drawing is accurate
Answers
Answer: all sides of the apartment would be cut in half.
Step-by-step explanation:
To draw a scale drawing using a different scale, convert the measurements from the original scale to the new scale by dividing them by the ratio between the scales. The resulting measurements are then used to create an accurate scale drawing.
To draw a scale drawing of the apartment using a scale of 4 ft to 1 cm, we need to convert the scale from the given 8 ft to 1 cm to the new scale.
Since the new scale is half of the given scale, we can divide the measurements in the given drawing by 2
to get the corresponding measurements in the new drawing.
We then use these new measurements to draw the scale drawing of the apartment.
For example, if a wall in the given drawing is 16 ft long, in the new scale drawing it will be 8 cm long. We repeat this process for all measurements in the given drawing to create an accurate scale drawing based on the new scale.
This drawing is accurate because we followed the conversion process correctly and used the new scale to determine the appropriate measurements for the scale drawing.
