Answer:
-2x-6=-2x-6
-6=-6
infinity many solutions
hope this helps
have a good day :)
Step-by-step explanation:
70
to find the answer do 60+x / 2 =65
Solver for x
multiply 2 on both sides to get 130
60+x=130
x=70
Answer:
D: 768
Step-by-step explanation:
First, he divides a piece of paper in half.
He gets two pieces.
Next, he cuts each of the pieces into three parts.
Thirdly, he cuts each of the 6 pieces into 8 pieces.
Lastly, he divides each piece into 16 parts.
He has 768 pieces in the end. (D)
Answer:
(0,7)
Step-by-step explanation:
For a set of ordered pairs to be a function, there needs to be "ONE" value of y for each unique x value.
Thus, we see that the 3 ordered pairs given have x values of 0, 2, and 3.
Now, we look in the answer choices and find which ones are 0, 2, or 3 in x-coordinate.
That would be only (0,7). Now the original set has x = 0 corresponding to y = 1
Is that true for (0,7)?? NO!
x = 0 will now correspond to "TWO" values of y.
THis will make this NOT A FUNCTION.
So, (0,7) is correct.
Answer:
r = 0.0424 cm (3sf)
Step-by-step explanation:
it makes 150 rev/sec
1 revolution = 1 circumference = 2pi*r
so every second the spool goes through 2*pi*r*150 of distance
we know that the rate of pulling is 40cm/sec
so 2pi*r*150 = 40
r = 40/(2pi*150), which is 0.04244131816 cm.
check: Circumference is 2pi*r = 0.2666
now multiply by 150rev/sec = 40 cm/sec
