y=31
The answer is A because there is a common difference of 3 and that makes it Arithmetric
Because the new function is y = 8x, we know each box costs $8.
The original brand costs $12 per box, so the new brand is $4 cheaper.
To find out how much we'd save if we bought 4 boxes, we can replace the value of x with 4 in each equation.
y = 12x
y = 12(4)
y = 48
y = 8x
y = 8(4)
y = 32
On buying 4 boxes, we'd save $16 with the new brand.
Answer:
Hope this helps
Step-by-step explanation:
x ≤ −1
You'll need to convert both speeds into yards per minute.
12 mph = 12 mph 1760 yd 60 min
---------- * ------------ * ----------
1 mile 1 hr
Note that "miles" cancels. So does "hours." Finish this work.
Then convert 4.4 ft/sec into yards per minute.
Then, finally, compare your two rates via subtraction of the smaller from the larger.
