The answer is D) 12
If you need proof, just comment.
Answer:
Step-by-step explanation:
The diameter is just the radius times two, so divide the diameter by two and you will have the radius of the circle.
Y = 3x - 6....to find the x int, sub in 0 for y and solve for x
0 = 3x - 6
-3x = -6
x = -6/-3
x = 2......so the x int here is 2
y = 3x - 6...when the slope is decreased by 2...
y = x - 6...this is the slope decreased by 2
0 = x - 6
-x = -6
x = 6.....so the x int here is 6
so ur answer is : the x int increases
Answer:
Is x = 4 a solution to the equation 6 = x + 2? YES
Is x = 4 a solution to the inequality 2x ≥ 9? NO
Step-by-step explanation:
Is x = 4 a solution to the equation 6 = x + 2? YES
we cans solve the equation 6=x+2 by clearing for x:
6 = x + 2
we move the +2 on the right as a -2 to the left:
6 - 2 = x
4 = x
this way we find that indeed x = 4 is a solution to 6 = x + 2.
Is x = 4 a solution to the inequality 2x ≥ 9? NO
Let's solve the inequality by clearing for x:
2x ≥ 9
we move the 2 that is multiplying on the left to divide on the right side:
x ≥ 9/2
x ≥ 4.5 ⇒ <u>x must be greater than or equal to 4.5</u>
thus, <u>4 is not a solution to the inequality</u> because 4 is less than 4.5
3 pipes take 12 hours
⇒ In 1 hour, the 3 pipes can fill 1/12 of the pool
2 of the pipes take 18 hours
⇒ in 1 hour, the 2 pipes can fill 1/18 of the pool
In 1 hour, the third pipe alone can fill :
Time needed :
