Answer:
The coordinates of point C are (8,8.5)
Step-by-step explanation:
The picture of the question in the attached figure
Let
----> coordinates of point C
we have that
The horizontal distance AB is equal to

The vertical distance AB is equal to

Find the horizontal coordinate of point C
we know that

so

----> equation A
----> equation B
substitute equation A in equation B



so
The x-coordinate of point C is equal to the x-coordinate of point A plus the horizontal distance between the point A and point C

Find the vertical coordinate of point C
we know that

so

----> equation A
----> equation B
substitute equation A in equation B



so
The y-coordinate of point C is equal to the y-coordinate of point A plus the vertical distance between the point A and point C

therefore
The coordinates of point C are (8,8.5)
Answer:
-10
Step-by-step explanation:
Let x = number
10 less than a number is the same number doubled
x-10 = 2x
Subtract x from each side
x-10-x = 2x-x
-10 = x
The number is -10
Answer:
A) −20
Step-by-step explanation:
−5/3 (−2/3 )(−18)
Multiply the first and second terms. A negative times a negative is a positive
-5/3 * -2/3 = 10/9
10/9 * -18
Rewriting for easier math
-18/9 * 10
-2 * 10
-20
Answer:
d 13
Step-by-step explanation:
Subtracting means adding the opposite.
To subtract -4, you add the opposite of -4 which is 4, so you add 4.
9 - (-4) = 9 + 4 = 13
Answer: d 13
