Answer:
We drawn the graph.
Step-by-step explanation:
We have a line segment AB = 6cm and a point P outside that a line segment.
We want to construct a line PQ that is parallel to line segment AB.
If PQ is parallel to longer AB, this means that a line PQ is equidistant from line segment AB everywhere.
We use the geogebra.org site to draw it.
We drawn the graph.
The area of a triangle is 1/2*base*height
So make your equation: 1/2*b*12=42
6*b=42
b=7
So the base is 7 inches long
Hope that helped!
I recommend using desmos when it comes to answering graphs and these type of questions. Got me through high school
Answer:
- c(m) = 39.95 +0.35m
- 85 minutes over 500
Step-by-step explanation:
Let m represent the number of minutes used over 500. Then the cost of the cell phone plan is ...
c(m) = 39.95 +0.35m
__
For a cost of 69.70, the number of excess minutes can be found by solving ...
69.70 = 39.95 +0.35m
29.75 = 0.35m . . . . . . . . . subtract 39.95
29.75/0.35 = m = 85 . . . . divide by the coefficient of m
The number of minutes of usage over 500 is 85.
Answer:
129 points
Step-by-step explanation:
Let L and C represent the scores of Luke and Caleb, respectively.
L = 2C -15 . . . . . Luke scored 15 less than twice the number Caleb did
L +C = 201 . . . . . they scored 201 points altogether
Add twice the second equation to the first:
2(L +C) + (L) = 2(201) + (2C -15)
3L +2C = 387 +2C . . . . simplify
3L = 387 . . . . . . . . . . . . .subtract 2C
L = 387/3 = 129 . . . . . . .divide by 3
Luke scored 129 points.
