Answer:
C
Step-by-step explanation:
A is incorrect because as x goes from 0 to 1, y jumped from 0 to 4
B is incorrect because as x goes up by 2, y at first goes up by 2 but then jumped to 4.
C is correct because as x goes up by 1, y goes up by 3
D is incorrect because y jumped from 0 to 10 and first but lowered to 5 after.
Step-by-step explanation:

6.An addition statement is a problem stated using words, and an algebraic expression is a problem stated using numbers and symbols. To translate an addition statement into an algebraic statement requires that you look for the words that represent known and unknown numbers.
9+x
So 9 + x is an algebraic expression. In the next few examples, we will be working solely with algebraic expressions. Example 2: Write each phrase as an algebraic expression.

Answer:
It satisfies both equations.
Step-by-step explanation:
The points on the graph of an equation are the values of the variables that satisfy the equation (make it true).
In a system of equations, you're generally looking for values of the variables that satisfy all of the equations in the system. That is, the solution will be a point on the graph of every equation in the system.
For a point to be on more than one graph, it must lie at a point of intersection of the graphs. If all of the graphs of a system go through the point of intersection, that point satisfies all of the equations, so is a solution of the system of equations.
Answer:
38.22
Step-by-step explanation:
Arc length = fraction of the circle * circumference
10 = fraction of the circle * 2*pi *15
10 = fraction of the circle * 30pi
Divide by 30 pi
10/30pi = fraction of the circle
1/3pi = fraction of the circle
A circle is 360 degrees
1/ (3*3.14) = x/360
1/9.42 = x/360
Multiply each side by 360
360/9.42 = x
38.21656051
Rounding to the nearest hundredth
38.22 degrees
