Answer:
y=10x
Step-by-step explanation:
1. The balloon is going up, so it won't be a negative number
2. It's going at a rate of 10 per second, and x represents seconds
Answer: y = 3
Step-by-step explanation: y−3=2(x+1)
We know that x=-1 and we want to solve for y
Put in x=-1
y-3 = 2(-1+1)
y-3 = 2(0)
y-3=0
Add 3 to each side
y-3+3 = 0+3
y =3
(1-sin(x))(1+sin(x))=1/1+tan(x^2)
I think the right side is tan^2 x ( the square of tan x)
Left side = 1 - sin^2 x
Right side = 1 / ( 1 + (sin^2 x / cos^2x))
= 1 / (cos^2x + sin^2x) / cos^2 x
Now sin^2 x + cos^2 x = 1 so
this = 1 / 1 / cos^2x
= cos^2x = 1 - sin^2 x = Left side - Proved
The answer to the variable r is r=-4
Answer:
x= 10/3
Step-by-step explanation:
1/250 : 2 = 1/150 : x
it's a simple problem of ratio and proportion
1/250 : 2 = 1/150 : x
⇒
⇒
x= 10/3
