Answer is A...first one y = -5x - 7
Answer:
Step-by-step explanation:
We have the equation:
Answer:
x = -4 , x = -1
Explanation:
Multiply by x on both sides to get rid of fraction
x(x + 4/x) = x(-5)
x^2 + 4 = -5x
x^2 + 5x + 4 = 0
Factor
(x+4)(x+1) = 0
x = -4 , x = -1
Answer:
His acceleration is 1.8m/s²
Step-by-step explanation:
acceleration, a = velocity, v / time, t
Velocity = 18m/s, unit is in m/s
time = 10 seconds, unit is in s
Therefore, a = 18m/s/10s = 1.8m/s²
