You answer is C because 7-(-2) is 9 and then u just had an X at the end .
Hope this helps:)
If it is a right triangle and AC is the hypotenuse, then AC is 5.
This is a Pythagorean Triple 3-4-5
If the cyclist traveled 2/3 of his journey already, then the remainder would be 1/3 of his journey, which we know is 30 miles. Double that and we have the miles he traveled during the first 2/3, 60. Then divide 60 by the miles per hour, 12, to get 5 hours. Add in the 3 hours from the remaining 1/3 of the journey and you have your total; the cyclist's trip took 8 hours.
Answer:
D is the correct answer.
Step-by-step explanation:
First find the slope: 2-5/8-9=3 So slope is 3
(y-y1)=m(x-x1) is the point slope formula
plug in the numbers (y-5) = 3(x-9)
y-5 = 3x-27
y=3x-22
