-- It'll be a lot easier if you clean up the function first.
You're not changing the function. You're just making it
easier to read and work on without mistakes.
Notice that 3x3=9 , so the function is f(x) = 9 - 4x + 5
Combine like terms, and the function is f(x) = 14 - 4x .
Much easier to work with.
-- Now, when somebody tells you to evaluate the function <em>for some number</em>,
just take their number, write it in place of 'x',and see what you've got.
Example:
f(x) = 14 - 4x
Evaluate f(x) for x = 3.
-- Write 3 in place of 'x' in the function: f(3) = 14 - 4(3)
-- 4(3) = 12 . So the function is f(3) = 14 - 12
-- Finish up the subtraction : <em> f(3) = 2</em>
You just evaluated f(x) for x=3.
Nice job !
Answer:
7/24
Step-by-step explanation:
Everything they are grilling is an amount of 1.
Then each item is a fraction of 1.
Add 3/8 and 1/3 and subtract from 1.
3/8 + 1/3 = 9/24 + 8/24 = 17/24
The veggie burgers and corn account for 17/24 of the total.
To find the fraction of mushroom, we subtract 17/24 from 1.
1 - 17/24 = 24/24 - 17/24 = 7/24
Answer: 7/24
It is linear for sure.
Because 12×12=144 and 144×12=1728
Ummmmmmmmmmm $3.45 or $3.50 <<<<(only if u need to round)
Answer:
Unlike most circle graphs, bar graphs compare exact amounts. Circle graphs are used when dealing with percentages, and the percentages of the pieces add up to 100 percent. In a bar graph, however, a scale is used to show the exact amount of each category. ... The bar graph shows the same results but in a different format.
