Question
1. The function f(x) = 4/5x - 3 has which x - intercept2. In order to make extra money, Josh decided to build smallbirdhouses in his garage. He had initial one-time overheadcosts of $725, and calculates his cost per birdhouse to be$4.50. Customers pay $9.75 per birdhouse. Which of theprofit models below must Josh use to calculate his profit p, formaking n, birdhouses?
3. When the equation dx + ey = f is solved for y, thetransformed equation is:
4. How long is a leg a of a right triangle whose other leg bmeasures 2h units, and whose hypotenuse c measures 4h units ( h > 0 ) ?
5. The expression 2-6 / 23 x1212 / 23 has a value best representedby which number below?
Explanation / Answer
1.) Plug y=0 into the equation to solve for the x intercept. So: 0 = (4/5)x-3 | Plugging 0 in for y 3 = (4/5)x | Adding 3 to both sides 3(5/4) = x | Multiplying both sides by 5/4 to clear the(4/5)x x = 15/4 Some of your questions say "below." It would be good toinclude whatever's below.
