x+ y = 90


x = 36 + 3y


x = 36 + 3(90 - x)


x = 36 + 270 - 3x


4x = 306


x = 153/2 = 76.5 degrees


Answer: 76.5 degrees


Check: y=90=76.5 = 13.5 degrees


3y+36 =3(13.5)+36 = 76.5 good

Varvara68 [4.7K]

Answer:

20.65 points.

Step-by-step explanation:  

We have been given that a star athlete at a local college scored 640 points during the 31 basketball games. We are asked to find the average number of points she scored per game.

To find the average number of points scored per game by player we will divide total number scored by the total number of games.

\text{Average number of points scored per game}=\frac{640}{31}

\text{Average number of points scored per game}=20.645161290322580\approx 20.65

Therefore, the average number of points scored per game by the player is 20.65 points.

F(x) is vertically stretched by a factor of 5/4 matches w/ f(x)-5/4
f(x) reflects the x axis matches w/ -f(x)
f(x) is translated 5/4 units up matches with f(x)+5/4
f(x) translated 5/4 to the left matches w/ f(x)-5/4

I didn't really know about this one but it seemed kind of easy, what was your first guesses and did you forget to put one more or was the question like that.


Hope this is right :) or if someone else has a different answer but in the meantime, good luck :)
