Answer:
8) No solution
9) n > -5 <em>(View explanation for info on how to graph)</em>
Step-by-step explanation:
<em><u>Question 8</u></em>
<em><u /></em>
<u>24+6k < -6(-4-k)</u> - Solve and graph
1) Distribute -6 to -4 and -k:
24+6k < 24+6k
2) Subtract 6k from both sides:
24<24
^ We know the following is false, therefore there is no solution to question 8.
<em><u>Question 9</u></em>
<em><u /></em>
<u>-2n-40 < 5(6+n)+7n</u> - Solve and graph
1) Distribute 5 to 6 and n:
-2n-40 < 30+5n+7n
2) Combine alike terms:
-2n-40 < 30+12n
3) Add 2n to both sides:
-40 < 30+14n
4) Subtract 30 from both sides:
-70 < 14n
5) Divide both sides by 14:
n > -5
6) To graph, plot an OPEN CIRCLE (<em>don't fill in the circle)</em> at point -5 and then draw an arrow pointing to the right!

Answer:240 miles in 4 hours
Step-by-step explanation:
1130cm square
Area formula is pixr^2
Pi x 19^2 = 1134.1149...
3.2 x 5 = 16
1.5 x 2 = 3
16 + 3 = 19
19 x 6 = 114
Rachel will run 114 miles in 6 weeks.
Answer:
1. f(0) = -2, f(2) = 0, f(3) = 1
Step-by-step explanation:
Substitute the numbers given for f(x) for the x in the function f(x) = 1(x-2)
so f(0) = 1(0-2) = 1(-2) = -2
f(2) = 1(2-2) = 1(0) = 0
f(3) = 1(3-2) = 1(1) = 1
Now you try the rest
