To solve for the X intercepts make y equal to 0. Then factor the quadratic. It would become (X-7)(X-3)=0. Solve for x in each case and the X intercepts are (3,0) and (7,0). The y intercept can be determined by making the X variables in the above quadratic equal to 0. The y intercept is 21, or (0,21).
Answer:
C.
y=2 · 3xy equals 2 times 3 superscript x baseline
Step-by-step explanation:
y=2 · 3 xy equals 2 tim
Becuase 80 is the same as 8 but has an extra 0 at the end (which makes it 80) and same for 20 to 2. 8 + 2 = 10 (now add a zero at the end). The answer should be 100.
6 groups of 3 6 times 3 which equals 18
and 18 divided by 4 is 4.5 so it takes 5 cars.
