For question 9, your answer would be -7
-56 = 8x
then swap the equation
8x = -56
8 x 7 = 56
so your answer would be -7 because the -56 is bigger.
That is false.
y=7 is just a simplified way of writing y = 0 x 1 + 7
Answer:
(- 4, - 7)
Step-by-step explanation:
given the 2 equations
2x - 3y = 13 → (1)
4x - y = - 9 → (2)
multiply all terms in (2) by - 3
- 12x + 3y = 27 → (3)
Add (1) and (3) term by term
(2x - 12x) + (- 3y + 3y) = (13 + 27)
- 10x = 40 ( divide both sides by - 10 )
x = - 4
Substitute x = - 4 in either (1) or (2) for corresponding value of y
(1) : - 8 - 3y = 13 ( add 8 to both sides )
- 3y = 21 ( divide both sides by - 3 )
y = - 7
Solution is (- 4, - 7 )
Answer:
There is a 1/3 chance it lands on each section
Step-by-step explanation:
Answer:
(-4,-9)
Step-by-step explanation:
Given a segment AB with endpoints with coordinates
A:
B:
The coordinates of the midpoint M of the segment AB are given by:
(1)
In this problem, we know that:
- The midpoint of the segment AB has coordinates
- One of the endpoint of the segment has coordinates
So we can find the coordinates of the other endpoint A by re-arranging eq.(1) above:
And substituting, we find:
So, the coordinates of the other endpoint are (-4,-9).
