First you need to find the cost of 1 can of nut:
let x represent the number of cans
4x=$9
divide both by 4
x=2.25
meaning 1 can costs $2.25
$2.25×7
=$15.75
meaning the cost of 7 cans is $15.75
Answer:
Pattern A start at 0 and uses the rule "Add 2"
Pattern B starts at 0 and uses the rule "Add 3"
Step-by-step explanation:
Given that Tai wrote 2 patterns then she made the corresponding numbers into ordered pairs and graphed them below. We have to find the pattern before ordering.
Now, the x-axis coordinates are 0, 2, 4, 6, 8
The pattern is A starts at 0 and uses the rule Previous value+2 i.e uses the rule "Add 2"
Now, the y-axis coordinates are 0, 3, 6, 9, 12
The pattern is B starts at 0 and uses the rule Previous value+3 i.e uses the rule "Add 3"
In order to find the area for a strange shape, you divide it up into simpler figures. In this case, you already know that it can be divided into 4 triangles, so find the area of each triangle and add them up. Hope this helped!
The new co ordinate would be (3,-1)
