Answer:
Brock is lying.
Step-by-step explanation:
Brock is lying because 4^-2 = 1/4^2 = 1/16 of a second!! (He'd have to hold on to a rocket to do 100 meters in that time!!).
Jim's time of 4^2 = 16 seconds is believable.
Answer:
<h3>B. It has infinite solutions</h3>
Step-by-step explanation:
Given the system of equations:
2t + w = 10 ..... 1
4t = 20 − 2w ... 2
From 1:
w = 10-2t ...3
Substitute 3 into 2 to have;
4t = 20 - 2(10-2t)
4t = 20-20+4t
4t = 4t
Let t = k
Substitute t = k into 1 and get w;
From 1: 2t + w = 10
2k + w =10
w = 10 - 2k
<em>k can take any integers. This shows that the solution to the equation is infinite</em>

Answer:
14
Step-by-step explanation:
It's a probability, divide favorable outcomes to total outcomes
Subtract 6 from the x value in the first one, and remember that slope intercept form is mx+b
