Answer:
D
Step-by-step explanation:
(f - g)(x)
= f(x) - g(x)
= 3x² - 4 - (x + 2) ← distribute parenthesis by - 1
= 3x² - 4 - x - 2 ← collect like terms
= 3x² - x - 6
y-y1 over x-x1 its almost the same as y=mx+b
I’m pretty sure it’s a candle but I’m not 100% sorry if I’m wrong!!!
A. -2x + 3y = -15
-2x + 2x + 3y = 2x - 15
3y = 2x - 15
3 3
y = ²/₃ - 5
A is correct.
B. y = ²/₃ - 5
B is also correct.
C. 6y = 4x - 30
6 6
y = ²/₃x - 5
C is also correct.
D. y + 3 = ²/₃(x - 3)
y + 3 = ²/₃(x) - ²/₃(3)
y + 3 = ²/₃x - 2
- 3 - 3
y = ²/₃x - 5
D is also correct.
The answer to the problem is A, B, C, and D.
Step-by-step explanation:
time ∝ number of door 1
time . ∝ 1/number of people. 2
compare equation 1 and 2
time . ∝ number of door / number of people
put k as constant
time = k number of door / number of people. 3
time =2. people=4 door = 10
putting in equation 3
2 = k (10)/(4)
2×4/10 = k
8/10 =k
4/5 =k
putting in equation 3
time= 4/5 number of door / number of people
now time =5 door= 25 people=?
5=4/5 (5)/ (number of people)
number of people =4/5 ×25/5
number of people= 4
