Answer:
Step-by-step explanation:
tanC ==7/25
PART 1):
f(x) = 3x – 5 if x < -1
Start with a filled in circle on (-1, -8). Use the slope to go up 3 and right 1 to make another point and drawn the line only going down.
Answer: WRONG.
Because correct inequality is x≤-1 not x<-1. Hence we will put a close circle not an open circle. at (-1,-8).
Also since slope is positive so graph will go upward not downward.
-----------------
PART 2):
f(x) = -2x + 3 if -1 < x < 4
Put an open circle on (-1,5) and open circle on (4, -5). Connect those points.
Answer: Correct
Because correct inequality is < or > so both end points will be open circles.
----------------
PART 3):
f(x) = 2 if x > 4
Put an open in circle on (4,2) then draw a horizontal line to the right.
Answer: WRONG.
Because correct inequality is x≥4 not x>4. Hence we will put a close circle not an open circle. at (4,2).
I would set this up as a a proportion:
·
17x = 1360
x = 20 cm
Answer:
20 ice cubes. Hope this helps!! ;)
Step-by-step explanation:
A 4 hours
This is because if you create the equation using $75 which is the starting fee and then $30 for every hour of playing music.
Equation: 75+30h<200
You subtract 75 from 200 and the divide that number by 200 you will get a decimal but you look at your answer choices and choose the closest number to your answer.
