Answer:
10
Step-by-step explanation:
After spending $8, Kyle had $20 left to buy $2 ride tickets. He could buy ...
$20/$2 = 10 . . . tickets
__
An equation for the total Kyle spent is ...
total spent = (entry fee) + (ride cost) × (number of rides)
28 = 8 + 2n . . . . fill in the known values
20 = 2n . . . . . . . subtract 8
10 = n . . . . . . . . . divide by 2
Kyle bought 10 ride tickets.
Well it's 33. The 5 step problem thing I'm not to sure of.
First you input the equation into the quadratic formula:
__________
x=<span><span><span>−<span>(<span>−2</span>)</span></span>±<span>√<span><span><span>(<span>−2</span>)</span>2</span>−<span><span>4<span>(1)</span></span><span>(5)</span></span></span></span></span>
</span> -----------------------------
2(1)
Next you simplify the formula:
___
x=<span><span>2±<span>√<span>−16
</span></span></span></span> ------------

This problem has no real solutions.
Point slope form
y-y1=m(x-x1)
slope=m
a point is (x1,y1)
slope=(y2-y1)/(x2-x1)
given
(-6,4) and (2,0)
slope=(0-4)/(2-(-6))=-4/(2+6)=-4/8=-1/2
a point is (-6,4)
x1=-6
y1=4
y-4=-1/2(x+6)

Answer:
Inequality Form:
y<2
Interval Notation:
(−∞,2)
The answer your looking for is: y<2
