It’s not, and the table would look like this:
Rental time: 1,2,3
Cost $: 37,62,87
The equation is already solved for the variable t To solve for any other variable simply rearrange theequation to have the indicated variable on one sideof the equals sign and everything else on the other. For example, to solve for a: t=an+b subtract b from both sidest-b = an divide both sides by n(t-b)/n = a Or: a = (t-b)/n Work in the same manner to solve for either b or n: b = t-an n = (t-b)/a
Answer:
equation of the table is y=30x+60
60 degrees is what the temperature starts at
to get to 440 degrees he needs 12 minutes and 40 seconds
Step-by-step explanation:
the change in y over change in x is 90/3 which is the slope
slope is 30
if slope is 30 then 30*2+b=120 60+b=120 so b=60 and it is the y intercept
440=30x+60
380=30x
x=12 2/3
x= 12 minutes and 40 seconds
And would be negative 2 over 3 and 2 over negative 3
Answer:
t = 4d + 5
Step-by-step explanation:
Since the slopes in the answer choices are different, we can just find the slope.
Use the formula (y1-y2)/(x1-x2) to find slope. Take points (1,9) and (2,13) and plug them it to get (9-13)/1-2). Simplify to get (-4)/(-1), which simplifies to 4.
The only answer choice with 4 as a slope is D, t = 4d + 5
