Answer: 11.2x -9.6
Step-by-step explanation:
7.2(x + 3) + 4(x - 3) - 12 - 7.2* (x + 3) + + 4*(x - 3) then
7.2x + 21.6 + 4x - 12 - Combining like terms 7.2x+ 4x and numbers + 21.6- 12
7.2x + 4x +21.6 -12 Then we have
11.2x -9.6
discriminant= b^2-4ac= (-2)^2-4(4)(9)= -140<0
since discriminant <0, graph is always positive, x has no real roots
19^2 + x^2 = 21^2
19^2 = 361
21^2= 441
361 + x^2 = 441
x^2 = 441-361 = 80
x = sqrt(80) = 8.944 round to nearest tenth = 8.9
Answer:
Step-by-step explanation:
This means:
- when x is equal to zero or less than zero, g(x) will always be 7.
- when x is more than zero, g(x) is
