Graph using the slope and y-intercept
Slope: —1
Y-intercept:2
The to this question is that it is a function
Answer: just graph these two equations
option a: y = 5x + 10
option b: y = 7.5x
and then tell at what number of event would having a card and not having a card is cheaper.
Step-by-step explanation:
the initial cost, $10, is your b value for the equation y = mx + b so yo would start here on the y axis. but for the second option you start at zero since you don't have a b value
1. Yes. Both ratios equal 2:3.
2. No. They do not equal each other.
3. No. They do not equal each other.
4. Yes. Both ratios equal 2:5.
5. Yes. Both ratios equal 4:9.
6. Yes. Both ratios equal 2:5.
Hope this helps!
Area = L x W
Area = (y+5) (y-5)
Use Foil to multipy (First, Outer, Inner, Last)
Area = y² -5y + 5y -25
Area = y² -25
