O All real numbers is the range of the function
<span>Given that for every $1 increase in the price of the t-shirts, they will sell 20 less shirts. The revenue function R(x) is giiven by R(x) = (400 - 20x)(10 + x) = 4000 + 200x - 20x^2. Therefore, the revenue function representing the revenue Mrs Bell's class earns from selling Hobbs Middle Jaquar t-shirts is given by R(x) = 4000 + 200x - 20x^2 where x represent the $1 price increases and revenue is equal to the number of t-shirts sold times the cost of each shirt.</span>
X it is a straight line and goes through the origin
-3x+5y=10 (add 3x on both side)
5y=3x+10 ( divide 5 to each term)
y=3/5x+2
slope is 3/5
y-intercept is 2
Answer:
40 degrees
Step-by-step explanation:
It is a vertical angle so because the right side is 40 degrees it is the same on the left side. The measure of Angle 1 is 40 degrees.
