- 90, 50 , 40
And
60, 50, 70
You could use the function:
f(x)=30+2x
100=30+2x
In which lets say he rode 3 rides. Plug in 3 for x.
100=30+2(3)
Then Multiply
100=30+6
Then combine 30 and 6 to get 36.
Then you can subtract 36 from 100 to get
$64 left over.
Assuming you can’t use the same topping twice,
10 x 9 x 8 = 720
Answer:
x-intercept is (-4,0) and the y-intercept is (0,-2
Step-by-step explanation:
There are 2 ways to find the y-intercept. One way is to put the equation in slope-intercept form. However, there is a more efficient way as well.
Another way to do it is to plug 0 in for x and y. The x-intercept will have the coordinate of (x,0). So to find the x-intercept you can plug in 0 for y and solve for x. To find the y-intercept do the opposite and plug 0 in for x.
So, first, plug 0 in for y
- x+2(0)=-4
- x+0=-4
- x=-4
Then plug in 0 for x
- 0+2y=-4
- 2y=-4
- y=-2
Therefore, the x-intercept is (-4,0) and the y-intercept is (0,-2).
