Answer:
False, this is not a function
Step-by-step explanation:
This would not represent a function
This would fail the vertical line test
One value of the input has more than one value for the output
Answer:
C) The cost increases $2.50 for every additional pair of shoes rented.
Step-by-step explanation:
Notice a pattern. When you buy a new pair of shoes, the total gets increased by $2.50 depending on how many pairs of shoes you buy. For example, starting with 1 pair of shoes, it costs $2.50, but when you buy another pair, the cost is $2.50+$2.50=2*$2.50=$5.00, and so on...
Therefore, the correct choice is C
Answer:
Packages A and C
Step-by-step explanation:
To find the ratio between the number of lifts to the cost we first remove the $ symbol and find out how much 1 lift will cost per package.
Package A = 3 : 30
Package B = 5 : 60
Package C = 12 : 120
Package D = 16 : 120
Now let's break it down.
Package A = 30/3 = $10 per lift
Package B = 60/5 = $12 per lift
Package C = 120/12 = $10 per lift
Package D = 120/16 = 7.5 per lift
So now we are able to know which packages have the same ratio.
Package A and C cost $10 per lift.
Answer:
one
Step-by-step explanation:
for general form : ax²+bx+c=0
delta = b²-4ac
so for this example delta is 8²-4×2×8 =0
we know if delta = 0 , we have just one real number solution
so the answer is 1
The perimeter of a rectangle is 2(w+l)
We can find the lengths by setting the equation equal to 12.
12=2(w+l)
12÷2=(2(w+l))÷2
6=w+l
6=1+5
6=2+4
6=3+3
These are the lengths of the sides of three rectangles with a perimeter of 12 units.
You're probably wondering why the third one has two of the same number, because that's usually how the lengths of sides of squares are, not rectangles.
Well, there's this wonderful thing about the rules of shapes.
<em>Squares ARE rectangles.
</em>Because they follow the rules for a rectangle, squares are also classified as rectangles.
So, the rectangle side lengths are as follows:
1 unit by 5 units
2 units by 4 units
3 units by 3 units
