(X-5)(-6+x) is -6x+x^2+30-5x which is x^2-11x+30 so Dan is correct Emily will have made a mistake when timesong either -6 x XOR -5 x x.
Answer:
one real solution
Step-by-step explanation:
We can use the discriminant to find the types of solutions
b^2 -4ac where ax^2 +bx+c=0
Since
x^2 -8x+16 =0
we know a=1 b=-8 and c=16
(-8)^2 - 4(1)(16)
64 -64 = 0
If the discriminant > 0 we have two real solutions
If the discriminant = 0 we have 1 real solutions
If the discriminant < 0 we have two complex solutions
Since it equals zero, we have one real solution
Answer:
Step-by-step explanation:
(-∞,-3) U (-3,8) U(8,∞)
Answer:
units to the right
Step-by-step explanation:
If we have a parent function y = Sin(x), the function
- y = Sin(x-b) would be the parent shifted b units right
- y = Sin (x+b) would be the parent shifted b units left
The function given is 
So from the rules, we can clearly say that it is parent function shifted RIGHT by units.
2nd answer choice is correct.
Answer:
x = 9. Rearrange variables to the left side of the equation: - x = - 5 - 4
Calculate the sum or difference: x=9
