Answer:
C; x <= -3
Step-by-step explanation:
-3 has a closed point on the number line so that means that the inequality includes -3 as an x value. The arrow in pointing to the left so that means that x is any value less than or equal to -3.
Answer:
Y=1

Formula: V = d / t => d = V*t
Name your relevant variables:
minimum speed limit: v
maximmum speed limit V
1) Tony's distance
2*v + 3.5*V = 355 miles
2) Ray's distance
2*v + 3*V = 300 miles
3) Finding v and V
You have a system of two equations each with the two variables.
You can solve that system by subtracting the second equation from the first one:
=> 0.5V = 55 => V = 55 / 0.5 = 110 mph
Now replace that value of V in any of the equations and solve for v
From the second one: 2v + 3V = 300 => 2v = 300 - 3V = 300 - 3(110) = 300 - 330 = - 30 mph
This value of v indicates that the conditions given are not valid. Both speed should be a positive value.
=> Tony's distance is 2*80 + 3.5*110 = 160 +
Answer:
-16
Step-by-step explanation:
x/-2 = 8
cross multiply.
-2(-2) = 0 (because you're cross multiplying)
8(-2) = -16
x= -16
