Yes and no, (4, 5) multiplied by 2 is (10, 8) but reversed. It depends on how you look at it because (10, 8) would be on the other side of the graph than (8, 10) which is the actually equivalent.
Answer:
y= - 1/2 (negative half) = -0.5
Step-by-step explanation:
−6y+3(12y)=20(y−1)+15
Multiply 3 and 12 to get 36.
−6y+36y=20(y−1)+15
Combine −6y and 36y to get 30y.
30y=20(y−1)+15
Use the distributive property to multiply 20 by y−1.
30y=20y−20+15
Add −20 and 15 to get −5.
30y=20y−5
Subtract 20y from both sides.
30y−20y=−5
Combine 30y and −20y to get 10y.
10y=−5
Divide both sides by 10
y= -5/10
Reduce the fraction -5/10 = -0.5 to lowest terms by extracting and cancelling out 5 .
S(t) = -4.9t^2 + 19.6t + 24.5
when it reaches the ground s(t) = 0
so we have -4.9t^2 + 19.6t + 24.5 = 0
solve this for t:-
-4.9(t^2 - 4t - 5) = 0
(t + 1)(t - 5) = 0
so required time t = 5 seconds
answer 5 seconds
Step 1 (simplify):
3+5x(2-1)
8 x 1
Step 2 (solve):
8 x 1 = 8
8 is your answer. Hope this helps :)
thus
and surely you know how much that is.
