Answer:
There are five triangles in a heptagon. A heptagon is a seven-sided polygon.
Step-by-step explanation:
the graph does not represent a function cause when you make a t chart and put all of the points on it some of the y's have the same x. to have a liniar function the x points and the y points have to be to one another accept the y points can have two of the different x points. you can also do the vertical line test to se if it is a function.
the answer is c.
Write the equations,
10 c + 5 f = 6900
5c + 3f = 3660
Double,
10c + 6f = 7320
Subtract,
f = 7320 - 6900 = 420
10 c = 6900 - 5f = 6900 - 2100 = 4800
c = 480
Answer: Cheeseburger 480 calories, fries 420 calories
Check:
10 (480) + 5 (420) = 4800 + 2100 = 6900 good
5(480) + 3(420) = 2400 + 1260 = 3660 good
Well.. There's 3y-2=y+4 right?
Add 2 and you get 3y=y+6
Minus y- you get 2y=6
Divide it at 2 and you get y=3.
Sorry for the explanation but I'm from another country and this is the best I can
