Answer:
First, enter x as 0.
y=2(0)+1
y=1.
Graph 0,1
Next, enter x as 1.
y=2(1)+1
y=3.
Graph 2,3
Then draw a line through the points.
Hope this helps plz hit the crown :D
Answer:
40
Step-by-step explanation:
26/sin(40 degrees) = 40.4488
An easy this to do is use desmos... an online graphing site that will allow you to graph the curves and points...
https://www.desmos.com/calculator
The alternate method is to subsitute each point into each equations...
I just did (-2, 2) into A... that point is not on the curve.. that would be the hard way. Subsituting x = -2 y = 18 so (-2, 2) isn't on the curve.
so eliminate A
repeat the process with B etc is (-2, 2) in on the curve, then select the next point and check.
That's why graphing is easier
I would say the third one would be the correct or the second one
ANSWER
The correct answer is

EXPLANATION
The expression given to us is,

We plug in

. That means we substitute 12 wherever we see x to obtain,

We simplify the parenthesis first to obtain,





Hence the expression evaluates to
