Answer:
a) The Total fee, that Mike charges for 4 hours of instruction is $152
b) The total fee, that Tony charges for 4 hours of instruction is $148
c) The difference between total fee Mike and Tony charge for 4 hours of instructions is $4
Step-by-step explanation:
a) What is the total fee, that mike charges for 4 hours of instruction.
Mike charges $12 for travel expenses and $35 per hour for instruction.
So, the equation will be: where h is number of hours and y is cost
Put h=4 and find cost
So, the Total fee, that Mike charges for 4 hours of instruction is $152
b) What is the total fee, that Tony charges for 4 hours of instruction
Tony's fee can be modelled by C=32h+20 where h is number of hours and C is cost
Put h=4
So, the total fee, that Tony charges for 4 hours of instruction is $148
c) What is the difference between total fee Mike and Tony charge for 4 hours of instructions.
Cost for Mike = $152
Cost for Tony = $148
Difference = 152 - 148 = 4
So, the difference between total fee Mike and Tony charge for 4 hours of instructions is $4
<h2>Answer:</h2>
Option C
<h2>Step-by-step explanation:</h2>When you rotate a point you could rotate it in Clockwise direction because that's how the hand of a clock move, or rotate it in Counterclockwise direction that's the opposite rotation. In math, counterclockwise is defined as being a positive rotation while clockwise is defined as being a negative rotation. Rotating a whole shape means we're rotating every point in the shape.
On the coordinate plane, consider the point (x,y). To rotate this point by 90° around the origin in counterclockwise direction, you can always swap the x- and y-coordinates and then multiply the new x-coordinate by -1. In a mathematical language this is as follows:
By applying this rule to every point we have:
The figure below shows the original shape in green while the rotated shape is the one in red. As you can see, this figure matches the option C.
