20 pages per day
so the variable attached to the number 20 would be "number of days"
so x represents the number of days
then 90 + 20(number of days) = (total number of pages)
so that makes f(x) = (total number of pages)
therefore your answer is 2.
Answer:
D) 4.7
Step-by-step explanation:
this perpendicular connection with the circle center cuts this intersecting line in half, which is therefore on both sides of x 6.5 long.
I assume 16 is the diameter, so the radius is 8.
therefore, x is one side of the right-angled triangle of
radius
x
half of the intersecting line
Pythagoras
8² = x² + (6.5)²
64 = x² + 42.25
21.75 = x²
x = 4.7

Answer: -1 < x < 3</h3>
Work Shown:
| x-1 | < 2
-2 < x-1 < 2 ... see note1 below
-2+1 < x-1+1 < 2+1 ... see note2
-1 < x < 3
- Note1: use the rule that |x| < k turns into -k < x < k for some positive real number k.
- Note2: Add 1 to all sides to isolate x
Answer:
joe needs to get proffestionals to do it
Step-by-step explanation:
2x + y =7 (1)
3x-y=8 (2)
(1) + (2)
5x = 15
x = 3
