Answer:
Sean jogged 3.125, Paul jogged a distance of 3.25, Rick jogged 3.33
Step-by-step explanation:
make the fractions into decimals once they are in decimal form you cna then go and place them into the correct order.
Answer:
<em><u>x=2, y=4</u></em> (as a point,) (2, 4) (last part is unnecessary unless you are graphing)
Step-by-step explanation:
Use substitution.
Substitute y for 2x.
Since y=2x, you can plug 2x into the place where y goes...
Instead of y=-1/2x+5
2x=-1/2x+5....Now solve
2.5x=5 (Sorry my computer cannot type fractions very clearly)
/2.5 /2.5 (dividing by 2.5 on both sides)
<u><em>x=2</em></u>
Now just plug x into any of the equations to find y (preferably the easier one).
y=2x becomes
y=2*(2)
=4
<em><u>y=4</u></em>

Answer:
<h2>
y = x² - 1</h2>
Step-by-step explanation:
y = -1 for x = 0 {point(0, -1)} means -1 at the end of formula
If we add 1 to y-coordinate of every given point we get the squares of x-coordinate:
(1, 0): 1² - 1 = 0
(2, 3): 2² - 1 = 4 - 1 = 3
(3, 8): 3² - 1 = 9 - 1 = 8
(4, 15): 4² - 1 = 16 - 1 = 15
So for any x:
(x, y) y = x² - 1
8*8=64 well 2*2=4 hope it helps
