Answer:The number is -1.5
Step-by-step explanation:
The answer is -1.5 because if you can't use a number less than -1.5 or greater than -1.5 than the answer should be -1.5.
For this case we have the following equation:
v = v0 + at
Where, we have the following values:
v0 = 20 meters / second
a = 1.5 meters / second2
t = 4 seconds
Substituting values we have:
v = 20 + (1.5) * 4
v = 26 meters / second
Answer:
The car's final velocity is:
v = 26 meters / second
Answer: x = 1/2, y = 4
Step-by-Step Explanation:
Lets solve it using Substitution Method :-
=> 2x + 3y = 13 (Eq. 1)
=> 4x - y = - 2 (Eq. 2)
From Eq. 2 :-
=> 4x - y = - 2
= - y = - 2 - 4x
=> y = 4x + 2 (Eq. 3)
Substitute value of ‘y’ in Eq. 1 :-
=> 2x + 3y = 13
= 2x + 3(4x + 2) = 13
= 2x + 12x + 6 = 13
= 14x = 13 - 6 = 7
=> x = 7/14 = 1/2
Substitute value of ‘x’ in Eq. 3 :-
=> y = 4x + 2
= y = 4(1/2) + 2
= y = 4/2 + 2
=> y = 2 + 2 = 4
Therefore; x = 1/2, y = 4
