answer answer is A.
A relation is a set of numbers that have a relationship through the use of a domain and a range, while a function is a relation that has a specific set of numbers that causes there to be only be one range of numbers for each domain of numbers. All functions are relations, but all relations are not functions. hope this helps but read this anyway
Answer:
a=-4
b=-4
Step-by-step explanation:
-0.113 blank =0.452x + 0.452
-0.113(a+bx) =0.452x + 0.452
-0.113a-0.113bx =0.452x + 0.452
so we have
-0.113a=0.452
a=-0.4520/0.113= -4
-0.113bx =0.452x
b=-0.452/0.113= -4
We have been given that a circle of a certain radius has an area which is numerically 5 times the value of the circumference. We are asked to find the radius of the circle.
We know that area of circle with a radius of r units is 
.
We know that circumference of a circle is 
.
5 times the value of circumference would be 
.
Now we will equate 5 times circumference with area as:
Let us solve for r.
Therefore, the radius of the circle would be 10 units.
Answer:
(2,-2)
Step-by-step explanation:
since the solution area is the shaded and dotted area, just plot the coordinates listed and see if they land in that space. by doing that, your answer should be the only one in that area: (2,-2)
