130 +145 +65+160+120 = 620
the total inside angles for a 6 sided polygon should = 720
so x = 720-620 = 100
B is the answer
I would suggest converting to fractions. -5.2 is equal to -52/10, and 3.9 is equal to 39/10. To divide -52/10 by 39/10, multiply -52/10 by the reciprocal of 39/10 (which is 10/39).
So you would set this up like:
-52 10
----- x ----- =
10 39
cancel out the 10s. just divide-52 by 39, and you have your answer.
or divide 52 by 39, just know that the answer will be negative.
52/39=1.33, or 4/3, or 1 1/3.
The correct answer is D I hope this helps
Answer:
From the graph, since the function is a parabola, the correct option is:
A. Quadratic parent function
The graph given is a parabola.
The function which is a graph in this format is a 2nd degree function, which is also called quadratic, hence, the correct option is A.
We have that
<span>y=−2x+5 --------> equation 1
3x−4y=2---------> equation 2
</span><span>substituting 1 in 2
</span>3x-4*(-2x+5)=2--------> 3x+8x-20=2--------> 11x=22-----> x=2
y=-2x+5-----> -2*2+5-----> y=1
the solution is
x=2
y=1
