The independent variable is the number of sweatshirts sold so it is answer A.
(Money raised is the dependent variable because it depends on the number of sweatshirts sold.)
Answer:
the correct answer is 4, or D
Step-by-step explanation:
the fish is descending, meaning is is decreasing in sea level. if it descends 16 feet (8 x 2) then this would be represented by -320-16 which is -336, not 336
So we know that x+y+<1(the one that is not labeled or doesn't have a number)=180 degrees.
We also know that x+y= 98 degrees.
<1 and 98 degrees are supplementary. so <1=82 degrees.
We know that the triangle is isosceles so y=82 degrees as well.
We also know that a traingle =180 degrees so x=16 degrees
