Answer:
Distance between two points= √(x2-x1)²+(y2-y1)²
D= 15units
Let "k" be the y-coordinate of A
A(-6,k)
B(3,2)
15= √(3--6)²+(2-k)²
Taking square of both sides to eliminate the square root.
15²=(9)²+(2-k)²
225=81+4-4k+k²
k²-4k - 140=0
Using Quadratic Formula to evaluate
k= 14 or k=-10
The Possible coordinates of A are
(-6,14) or (-6,-10)
Answer:
Infinite solutions.
Step-by-step explanation:
Use the elimination method:
15x - 5y = -20
-3x + y = 4 Multiply this equation by 5:
-15x + 5y = 20 Now add this to the first equation:
0 = 0
So the 2 equations are the same and there are infinite solutions.
R + 9
Expression would be r+9=j
J represents the miles that Jessica rode. Since Jessica rode 9 miles farther, you must add 9 to the amount that roger rode.
Answer:
(x, y ) → (x + 2, y - 4 )
Step-by-step explanation:
Compare the coordinates of 2 corresponding points in the original and the image, that is
B(- 5, 4 ) → B'(- 3, 0 )
To translate from B → B'
We require a shift of 2 units right in the x direction and 4 units down in the y direction, that is
(x, y ) → (x + 2, y - 4 ) ← translation rule
