The above is 60 different ways, but now B C D E F G H I J have to come first, and the proses starts again, until we have covered them all. I'm not going to write them all out but in theory, there is 540 different ways. 9*60=540.
Y=2x+1
x is the input, so the 2x will make it twice the input, and the +1 will make it one more, therefore y(the output) is one more than twice the input :)
Answer:
y=2x-8
Step-by-step explanation:
<em>Slope-Intercept Form </em>
<em>y=mx+b where y and x are variables, m is the slope, and b is the y-intercept</em>
<u>1. Find slope using the slope formula </u>
You now have
y=2x+b
<u>2. Plug in one of the given points into the equation and solve for b</u>
y=2x+b
2=2(5)+b
2=10+b
-8=b
<u>Final Answer:</u>
y=2x-8
Answer:
The hula hoop rolls 879 \text{ cm}879 cm.
Step-by-step explanation:
Answer:
See below
Step-by-step explanation:
The patties (3 packs)
12x3= 36
The buns (4 packs)
9x4= 36
cost:
3x$4.98= $14.94
4x$2.16= $8.64
Add them to equal the total cost
= $ 23.58
