Answer: see below
<u>Step-by-step explanation:</u>
Write each equation in y = mx + b format where m is the slope and b is the y-intercept.
Left side: -4 ≤ x < -1
If you continue the line through the y-axis it will pass through (0, 4) --> b = 4
The rise over run is -1 over 1 --> m = -1
y = (-1)x + (4) --> y = -x + 4
Right side: -1 < x < 4
The line passes through (0,0) --> b = 0.
The rise over run is -1 over 1 --> m = -1
y = (-1)x + (0) --> y = -x

Step-by-step explanation:
To solve this, you either need x or y. So x or y can be the missing values. The most you can do is simply move one of the terms to the other side.
Answer:
I think its 300
but wouldn't that be like a 2 digit number like 30? scince they are only 10 blocks 10 + 10 + 10 (3×10= 30)
If you dont understand just coment.
Answer:
Should be D: Area multiplied by 1/3
Step-by-step explanation:
So since your radius is being multiplied by 1/3, so is your area. I think.
I'd say it's "convergent and doesn't have a sum"
because it's multiplying by 3 to get every new number and switching between ± after every new number. there is no sum because it's an infinite series.
