Answer: -2
Step-by-step explanation: 4-8= -4 then it ends up being -2r-4=0
Then you add 4 to 0 so -2r=4 then divide
Answer:
For different x values ,we get unique y value. So, Yes the Statement is true that , A function is a rule that assigns each value of the independent variable to exactly one value of the dependent variable.
Step-by-step explanation:
Answer:
10π feet, or about 31.42 feet
Step-by-step explanation:
Diameter = 2 times radius, so the radius is 5 feet.
The question is asking us for the circumference - the distance around the circle. Plug our radius into the formula.
C = 2πr
C = 2π(5)
<u>C = 10π feet = about 31.42 feet</u>
Answer:
Step-by-step explanation:
"Which ordered pair" implies that there were several answer choices for this problem. It's important that you share such answer choices.
2x+4y=6x−y reduces to 5y = 8x, and so y = (8/5)x
If we choose x = 2, then y = (8/5)(2) = 16/5 is a solution of the given equation. There are an infinite number of such solutions. All lie on the line y = (8/5)x.
