They are -9 and 8. because since 9 times 8 is 72, you need the 9 to be negative to add to -1
21 fewer stars than three times a number h
21 - (3 x h)
You just have to find what will make both sides equal. So calculate -4 x (-6+ 5.7)
Answer:
44
Step-by-step explanation:
-8(-8+2)-4
1) Simplify <u>inside the parenthesis</u>: (-8+2)
-8(-6)-4
2) Multiply -8 and -6:
48-4
3) Simplify:
44
You can find the x intercept by setting y to 0 and factor the equation.
0=2x^3+3x-2
0=(2x-1)(x+2)
We can make this equation =0 if x is -2 and 1/2.
So the x intercepts are (-2,0) and (0.5,0)
