Rational because it terminated
So u want to add all of the previous scores together and divide them by the number of scores [i.e: 79+91+64+65+71= 370 then u divide. 370/5 (since there are 5 sets of scores) which gets you 74.] Then it's kind of a guess and check from there.
Answer: 92
Answer:
a. 3x +51=180
x=43
b. 3(43)+51 =180 51 degrees; 129 degrees
Step-by-step explanation:
3x +51 =180
3x=180-51
3x=129
x=43
Hmmm the y-intercept is at -2? what does that mean? well, is where the graph "intercepts" or touches the y-axis, and when that happens, x = 0, so the point is really ( 0 , -2 ).
and we know where the vertex is at. Let's assume a vertical parabola, in which case the squared variable is the "x".
Answer:
x=1
Step-by-step explanation:

You substitute
for y in the second equation, because it is equal to y.

Alternate Method:
set both equations equal to y

Then you have

And you substitute one of the equations in for y in the other one

multiply both sides by 2

and solve
