Answer:
x < -3
Step-by-step explanation:
1. To put this inequality on a number line, we first must solve it.
Step 1: Subtract 15 from both sides.
Step 2: Divide both sides by 5.
2. Now that we know x < -3, let's graph it!
- Since it's less than, we make the number line point to the left, and we make the circle open.
B. Yes, because as x increases, y also increases
X Y
1 5 (1 x 5)
2 10 (2 x 5)
3 15 (3 x 5)
5 25 (5 x 5)
Answer:
The answer is $33.6
Step-by-step explanation:
Each small package costs him $2.80
3 small packages will cost him 3 x $2.80 = $8.4
Each large package costs him $3.60
7 large packages will cost 7 x $3.60 = $25.2
Cost to send 3 small packages and 7 large packages = $8.4 + $25.2
= $33.6
