Answer:
a) the slope is 2/-1 or just -2
b) the slope is 1/1 or just 1
Step-by-step explanation:
You can find slope (rise/run) by picking a point on the graph. For example on question a I chose the point (-2, 1) i then counted how far my run was, which is 2, and my rise (or how far down it went) was -1. Therefore my slope was 2/-1 or just -2.
Answer:
Step-by-step explanation:
I will assume that you meant: (-3/7)(y-28) - (1/21)y
Using the distributive property of multiplication, we get:
(-3/7)y + (3/7)(28) - (1/21)y
Let's first reudce the middle term. We get: 12
Then we have:
(-3/7)y + 12 - (1/21)y
Here there are two different denominators. We must combine the y terms. The LCD here is 21. Multiplying (-3/7)y by 21/21, we get the equivalent:
-9y
------ + 12 - (1/21)y
21
or:
-9y 21
------ + 12----- - (1/21)y
21 21
Combining the y terms, we get (-10/21)y:
-10y 252
------- + -------- = (1/21)(-10y + 252)
21 21
Answer: B
Step-by-step explanation:
B is the only one of the tables that goes up with a order
Answer:
$2 for 1 ticket, 7 tickets for $14, $18 for 9 tickets, 10 tickets for $20
Step-by-step explanation:
Since we know that it $8 for 4 tickets, we can simplify the ratio down to 2:1, meaning that each ticket is $2.
