I'm not familiar with this notation, but believe it means that you are to reflect point P over the line y=1. If you were reflecting P over the x-axis (line y=0), the result would be (-2,-7). However, you are to reflect P over the line y=1. The y-coordinate of (-2,7) is 7, which is (7-1), or 6, units above the line y=1. So, going in the other direction (reflecting P in y=1), you count 6 units down from y=1. Note how 1 + 6 = 7 units. New coordinates are (-2,-6).
Be
, a rate of change is defined by the following equation:
So, the problem establishes that we need to find out two points with an average rate of -60. So, the table above shows five points. Hence, we will take two of them, say:
Therefore:
So these two points are the ones we were looking for.
Answer:
X=4
Step-by-step explanation:
5x-4=16
+4 +4 Add 4 on both sides
5x=20 Divide both sides by 5
x= 4
Hope this helps!
Answer:
The annual difference in the cost between the two cars in gasoline plus monthly payment per month will be $856.67.
Step-by-step explanation:
Car option "A" gets 18 miles per gallon of gas (MPG) and has a monthly payment of $368.
Now, yearly 12000 miles will consume gallons of gas.
Now, if the gas costs $2.89 par gallons, then yearly fuel cost is $(666.67 × 2.89) = $1926.67
Hence, the yearly cost for option A will be $(1926.67 + 368 × 12) = $6342.67.
Now, car option "B" is a hybrid and gets 60 MPG with a monthly payment of $409.
Now, yearly 12000 miles will consume gallons of gas.
Now, if the gas costs $2.89 par gallons, then yearly fuel cost is $(200 × 2.89) = $578
Hence, the yearly cost for option B will be $(578 + 409 × 12) = $5486.
So, the annual difference in the cost between the two cars in gasoline plus a monthly payment per month will be $(6342.67 - 5486) = $856.67. (Answer)
