a)
value of y is decreasing
b) value of y is decreasing
c) because at x = 5 denominator becomes 0 and divide by 0 not allowed so showing ERROR
Is this what your asking: (x+3)(x^4 - x^2 + 5)
If you are then:
(x+3)(x^4 - x^2 + 5)
= (x+3)(x^2 + 5)
= x^3 + 3x^2 - 5x - 15
Looks kinda confusing but yh... Anyway, hope it helped :)
Answer:
m = 0.8
Step-by-step explanation:
The mean can be calculated as:
Then, all the values can be added and the expression turns into:
The expression can be simplified by multiplying on both sides by 6:
Which makes m = 0.8
Answer:
2
Step-by-step explanation:
1 + 1 = 2. It doesn’t get much simpler than that.
For the number 7, begin by solving for k.
Remember your discriminant rules:
k is greater than 0, there are 2 real solutions
k is equal to 0, there is one real solution
k is less than 0, there are no real solutions
On number 8, solve for a, and then figure out the number of solutions using the rules above.
Hope this helps!
