after watching a two minute video on how to tell if a relation is a function, I can confidently tell you that the answers are 2, 3, & 4.
<h3>
step-by-step explanation</h3><h3>
</h3>
answers 3 & 4 are the x and y coordinates of the points.
this relation is not a function because it does not pass the vertical line test.
( the vertical line test is where you look at all the vertical lines on the page and check if any of them have multiple dots on them. in this case, the line at x coordinate 1 has dots on both (1, 1) and (1, -1) )
Answer: Kate ran about 4.82803 kilometers.
Step-by-step explanation:
So 1 mile ≈ 1.60934 kilometers.
To find out how far Kate ran in kilometers, you can multiply how far she ran in miles by 1.60934.
3 × 1.60934 ≈ 4.82803
Kate ran about 4.82803 kilometers.
Answer:
a) 5 pizzas need to be ordered and half of a pizza will be left over aka 0.5
b) $45
Step-by-step explanation:
24- sqrt(720/4) divide 720 by 4
24 - sqrt (180) now break down 180 to 9*4*5
24- sqrt(9) *sqrt(4) *sqrt (5) so 9becomes 3, 4 becomes 2
24- 3*2*sqrt(5) multiply 3 and 2
24-6sqrt(5)
3a + 2ab - 6 + 2b - ab
First, gather like terms. / Your problem should look like: (3a - 6a) + (2ab - ab) + 2b
Second, simplify. / Your problem should look like: -3a + ab + 2b
Answer: -3a + ab + 2b
