Answer:
31 degrees
Step-by-step explanation:
1. triangle= 180 degrees.
2. 84+ x + (180-115)= 180
3. 84+65+ x= 180
4. 180- 149= 31
5. x= 31
<u>Part A:</u>
lines y=-2x+9 and 4x+2y=4 can be used to create a system of equation that has no solution because none of the lines intercept on a graph.
<u>Part B:</u>
lines y=2x+2 and 6x-3y=6 can be used to create a system of equation that has infinitely many solutions because again none of the lines intercept on a graph
<u>Part C:</u>
The lines y=1/2x+1 and 4x+2y=4 can be used to create a system of equations with one solution because on a graph both lines intersect at one point.
The Graphs Are Shown Below.

Hey there!
First, we'll solve for x = 0.
The first step is to replace x with 0 anytime it appears in the equation.
f(0) = 7(0) + 2
Multiply 7 by 0 next because multiplication comes before addition in PEMDAS.
f(0) = 0 + 2
Then, add 2 to 0 since it is the last step.
f(0) = 2 The value of f(x) when x = 0 is 2.
Now we can solve for x = 1.
The first step is to replace x with 1 anytime it appears in the equation.
f(1) = 7(1) + 2
Multiply 7 by 1 next because multiplication comes before addition in PEMDAS.
f(1) = 7 + 2
Then, add 2 to 7 because it is the last step.
f(1) = 9 The value of f(x) when x = 1 is 9.
Hope this helps!
