The car travels at 70 mph. </span>
<span>so the equation for the car is: 70(h-2) </span>
Answer: n>320
Explanation:
Let's solve your inequality step by step.
Step 1: Simplify both sides of your inequality
n/-8 < -40
-1/8n < -40
Step 2: Multiply both sides by 8/(-1).
(8/-1)*(-1/8n)< (8/-1)*(-40)
n>320
----Your answer is n>320.----
solve by elimination
we can see that we can eliminate y from both equations by mulitpying the 2nd equation by 2 and adding them
x+6y=1
<u>4x-6y=64 +</u>
5x+0y=65
5x=65
divide both sides by 5
x=13
subsitute back
x+6y=1
13+6y=1
minus 13 both sides
6y=-12
divide by 6 both sides
y=-2
solution is x=13 and y=-2 or (13,-2) is the solution

3 * ( - 1 1/2 ) =
= 3 * ( - 1 - 1/2 ) =
= 3 * ( - 1 ) + 3 * ( - 1/2 ) =
= - 3 - 3/2 = - 4 1/2
Answer: - 4 1/2
