Using the <em>system of equation</em> created, Emily will catch up Lucy after 30 seconds
Given the Parameters :
- Lucy's distance = 2t
- Emily's distance = 5t
<u>We can set up an equation to represent the required scenario thus</u> :
Emily's distance = Lucy's distance + 90
5t = 2t + 90
We solve for t
<em>Collect like terms</em> :
5t - 2t = 90
3t = 90
Divide both sides by 3 to isolate t
t = 90/3
t = 30
Therefore, Emily will catch up with Lucy after 30 seconds

Answer:
k ±16
Step-by-step explanation:
Evaluate x^2 + 8 x + k where x = -4:
x^2 + 8 x + k = k - 4 8 + (-4)^2
(-4)^2 = 16:
k - 4 8 + 16
8 (-4) = -32:
k + -32 + 16
Grouping like terms, k - 32 + 16 = k + (16 - 32):
k + (16 - 32)
16 - 32 = -16:
Answer: k ±16
