Answer:
y-(-1)=5/6(x-8)
Step-by-step explanation:
The formula for setting up point-slope form is y-y1=m(x-x1). You can plug in the numbers in the missing spots.
8 because 24 candles going into 3 boxes is 24 divided by 3 which is 8
Answer:
(- 3, 5 ) & (-2,7)
Step-by-step explanation:
Under a counterclockwise rotation about the origin of 90°
a point (x, y ) → (- y, x ) , thus
(5, 3 ) → (- 3, 5 )
Under a counterclockwise rotation about the origin of 90.
a point (x, y ) → (- y, x ) , thus
(7, -2 ) → (-2, 7)
1. {2x−3y=9
{3x+5y=4
2. {(2x−3y=9)×5
{(3x+5y=4)x3
3. {10x-15y=45
{9x+15y=12
4. (10x-15y=45) + (9x+15y=12)= (19x=57)
5. (19x=57)÷19
6. x=3
7. 2(3)-3y=9
8. 6-3y=9
9. -3y=9-6
10. (-3y=3)÷(-3)
11. y=-1
Answer: x=3 and y=-1
