It’s something that’s for sure good luck!
13. No
14. No
15. Yes; Domain: (-4,3) Range: (-4)
Answer:
( x + 1 ) ^ 3
Step-by-step explanation:
f(x) = 3√x - 1
replace x with y
x = 3√y - 1
solve for y,
x = 3√y - 1
x^3 + 3x^2 + 3x + 1 = (x+1)^3
HOPE THIS HELPS :)
Answer:
definitely equation B
steps:
multiply 12 by the hours, and add 15. for each part, it will equal the total charge. 12*2+15 and so on. hope this helps
<span>x+5y=8 ----------------- (1)
</span>y=3x ----------------- (2)
Substitute (2) into (1):
x + 5(3x) = 8
Distribute 5:
x + 15x = 8
Combine like terms:
16x = 8
Divide both sides by 16:
x = 0.5
Substitute x = 0.5 into (2):
y = 3(0.5)
Distribute 3
y = 1.5
Answer: x = 0.5, y = 1.5
