5x - 4 = 2x + 1
5x = 2x + 5
5/2 = 2.5
2.5x = 5
x = 2 got you fam
Answer:
There are 5 turning points at x = -3, -1.11, 0, 1.44 and 4.
Step-by-step explanation:
The product rule for 3 terms is
F' (x) = f'(x) g(x) h(x) + f(x) g'(x) h(x) + f(x) g(x) h'(x)
F(x) = x^2(x - 4)^7 (x + 3)^6
F' (x) = 2x(x-4)^7(x+3)^6 + x^2 7(x - 4)^6 (x + 3)^6 + x^2(x-4)^7 6(x+3)^5 = 0 at the turning points.
That is some equation!!
By observation, 3 roots are x = 0 , x = 4 and x = -3 so there are turning points at these values of x.
I'll use software to graph it to find any more real solutions - they are -1.11 and 1.44 to nearest hundredth.
Answer:
4. 2x^2 - 2x.
Step-by-step explanation:
Adding the 2 functions:
Area of the 2 triangles = x^2 + x + x^2 - 3x
= .2x^2 - 2x
we call n - the number
2×n + 15 = 3×n + 8
2×n - 3×n = 8 - 15
-n = -7 │ ×(-1)
n=7
Answer: it should be <u><em>D</em></u> i hope this helped (if it did let me know)
