This is a proof that the angles in a triangle equal 180°:
The top
line (that touches the top of the triangle) is
running parallel
to the base of the triangle.
So:
<span>
<span>angles A are the
same </span>
<span>angles B are the same </span>
</span>
And you can easily
see that A + C + B does a complete
rotation from one side of the straight line to the other, or <span>180°</span>
<span>11+4 (x+7)^2
Substitue 2 for x
</span><span>11+4 (2+7)^2
Multiply the numbers inside of the parenthesis by the exponent
11+4 (4+49)
Add 4 to 59
11+4 (54)
Add 4 to 11
15(54)
Multiply
Final Answer: 810</span>
The cost per mile driven represents the slope of the function. So b. 15 cents per mile driven is the slope-the price increases as the number of miles increase.
70°
(the sum of the angles of a triangle is 180°
180 - 40 = 140.
140/2 = 70
The other 2 angles are 70°
70° + 70° + 40° = 180°).
Answer:
5. Not sure
6. Its linear since the first difference is constant.
7. Linear since its a line.
8. Slope/Rate of Change/M = Rise over Run = rise/run.
From the left point to the right, the rise is 3 and run is 10.
M = 3/10.
