If mAngle3 = 29°, what is mAngle4?
1 answer:
Please consider the attached graph.
We have been given that measure of angle 3 is 29°. We are asked to find the measure of angle 4.
Upon looking at our diagram, we can see that angle 3 and angle 4 are linear angles.
We know that linear angles add up-to 180 degrees, so the sum of measure of angle 3 and angle 4 will be 180 degrees.
Therefore, the measure of angle 4 is 151 degrees.

The point-slope form equation for this line is y₁ - 9 = 4 (x₁ - 1), or D.
Since these are all in point-slope form, all we need to do is find the slope and then input one value of (x, y) into the points. We start with the slope.
m =
m =
m =
m = 2
Now we need to input the values of one of the points and slope into the point slope equation: y₁ - y = m(x₁ - x).
Inputting (1, 9), we get
y₁ - 9 = 4 (x₁ - 1)
The equation that fits it is D., so that means that the only answer to this question is D.

Answer:
The cost of lesson for 9 hours on weekdays and 3 hours on weekends
Step-by-step explanation:
Given
Required
What does 9m + 3(1.2m) represent
The expression can be split to:
9m and 3(1.2m)
<u>For 9m:</u>
From the question, we understand that:
Multiply both sides by 9
This means that:
9m = the cost of lessons for 9 hours on weekdays
<u>For 3(1.2m):</u>
From the question, we understand that:
Multiply both sides by 3
This means that:
3(1.2m) = the cost of lessons for 3 hours on weekends
Hence, the expression represents:
The cost of lesson for 9 hours on weekdays and 3 hours on weekends
