Answer:
R=7
Step-by-step explanation:
R=1+3w
This is a classic substitution question.
Just replace the w with 2.
R = 1+3(2)
You only need to multiply 3 with 2.
R = 1 + 6
R= 7
The slope of the horzontial line is always 0
Just plug in number for x and plot done the point to graph y=3x
To solve this question we must first find out what is x.
X + x - 4 = 82 degrees
2x - 4 = 82
2x = 86
X = 86/2 = 43.
Here x would be 43 degrees.
We can add up the angles because we know the angle of DAC and the CAB angle add up to give 82 degrees.
