Hi! So, the base fee was $14.99, which is the price you only pay one time. $0.83 was charged per mile driven, so the price changes constantly per mile driven. He had to pay $238.26 total when he returned the truck. To make this problem easier to solve, let's make an equation in this form: 14.99 + 0.83m = 238.26. In these kinds of formulas, suntract 14.99 from both sides to make the "m" by itself. When you do that, you get 0.83m = 223.27. Now to find the answer, divide each side by 0.83 to isolate the "m". 223.27/0.83 is 269. Let's plug it in to see if it works. 269 * 0.83 is 223.27. 223.27 + 14.99 is 238.26. There. Jose drove 269 miles with the truck. m = 269.
Your answer would be 42.5.
Divide 106.25 by 5 (which is 21.25) then multiply 21.25 by 2.
Answer:
11. y = -2x - 4.
12. y = x - 5
Step-by-step explanation:
11. the given points on the line are ((-2, 0) and (0, -4)
The slope of the line
= difference in y values / corresponding difference in x values
= ( - 4 - 0) / 0 - (-2))
= -4 / 2
= -2.
The general form of a straight line is y = mx + c where m = the slope and c = y value of the intercept on the y-axis.
So the equation is:
y = -2x - 4.
12.
The points are (1, -4) and (3, -2).
The slope is (-2 - (-4)) / (3 - 1)
= 2/2
= 1.
So the equation is
y = 1x + c
We find c by plugging in the point (1, -4):
-4 = 1 + c
c = -4 - 1
c = -5.
The equation is y = x - 5.
3 -1i + 21i -7i2 now you have to fix the last factore because you have to change the imaginery i this would give you the answer of 3 - 1i + 21i +7 now add common factor which would give you the final answer of 3 +20i +7
