Answer: a
Infinitely many
Step-by-step explanation:
Solve by substitution:
1) Solve 
for 
:
2) Substitute 
for in 
:
3) Simplify both sides of the equation:
4) Add -2 to both sides of the equation:
5) Simplify both sides of the equation:
Therefore, there are infinitely many solutions.
Solve by elimination:
You cannot solve this system by elimination
Solve by graphing:
The 
equations are on top of each other, therefore, the system of equations has infinitely many solutions.

Answer:
3.14
Step-by-step explanation:
The formula for the area of a circle is ...
A = πr²
The constant of proportionality is the constant in this equation: π. To two decimal places, the value of π is 3.14.
The constant of proportionality is about 3.14.
Answer:
7/3
Step-by-step explanation:
We can find the slope of a line given two points by
m = (y2-y1)/ (x2-x1)
= (3--4)/(4-1)
= (3+4)/(4-1)
7/3
Answer:
False
Step-by-step explanation:
the domain is the set of numbers you can plug in, and the range is what comes out
4 is shown in both ovals, but we see that there is no arrow pointing from the left oval to the 4 in the right oval, meaning that no value in interval [1,5] has a value of 4.
55,57,59
Let the smallest integer = x
171= (x) + (x+2) + (x+4)
171= 3x + 6
3x = 165
x= 55
therefore the integers are 55, 57, 59
