Answer:
f(x)=-3x+4
(can't see some of your choices)
Step-by-step explanation:
We want x to be independent means we want to write it so when we plug in numbers we can just choose what we want to plug in for x but y's value will depend on our choosing of x.
So we need to solve for y.
9x+3y=12
Subtract 9x on both sides
3y=-9x+12
Divide both sides by 3:
y=-3x+4
Replace y with f(x).
f(x)=-3x+4
2. Fraction
3. -1 & 1/4
4. -5/7
Minus 32a from both sides
17d=176-32a
divide both sides by 17
d=
20^2 + (x-8)^2 = x^2
x^2 = 400 + x^2 -16x + 64
16x = 464
x = 29 = hypotenuse
Double - Check
29^2 = 20^2 + 21^2
841 = 400 + 441
Answer: 6.501
Step-by-step explanation:
so we are not rounding to the nearest TENTH... we are not rounding to the nearest HUNDRETH... we are rounding to the nearest THOUSANDTH.
so it would be whichever 8 is closest to: 10 or 0? 8 is closest to 10.
so 6.5008 becomes 6.501
