Answer:
135
Step-by-step explanation:
A tutor charges 30.00$ for two hours of tutoring how much money would the tutor make in nine hours
x = -2 - it's a vertical line with undefined slope.
The line parallel to the vertical line is vertical.
<h3>Therefore your answer is c) undefined.</h3>
Answer:
24hours
Step-by-step explanation:
let Evan be x, Tyler=x-12,equate;1/x+1/(x-12)=1/8,to get x=24 or 4.The correct value of x=24 because if you take x=4 means that Tyler=-8hours which is impossible
Answer:
(1,3)
Step-by-step explanation:
1. Solve y-x=2 for x. You should get y=x+2.
2. Substitute that for y in the other equation. the equation should now look like this:
x+x+2=4
3. Simplify: you should find that you get 2x=2. Simplify once more. You should get that x=1.
4. Substitute into first original equation. This should look like this: y-1=2
5. Solve: y=3
Answer: (1,3)
X = measure of 1st angle
y = measure of 2nd angle
x + y = 180
y = 3(x+25)
Therefore,
x + 3(x+25) = 180
x + 3x +75 = 180
4x = 105
x = 26.25
So the measure of the 1st angle is 26.25 and the 2nd is 153.75
