Okay so to find this you need an equation to find x. for you have 5x+x=180
6x=180 divide both sides by 6 you get x=30 now you can double check. one angle is 30 and one is 5*30 see if you get 180 you 30+5*30 5*30=150+30=180 so it's correct. so x=30 so to find the smallest angles could be x=180-5x
i hope this helped you have an amazing day!!
Let's first calculate the roots of f(x) = x³-18x²+101x-180
a) f(4) = 4³ - 18.(4²) +101.(4) -180 =0, then x=4 is a root.
b) to find the 2 other roots divide x³-18x²+101x-180 by (x-4) = x²-14x+45
c) this quadratic equation has the following roots: x=5 and x=9. Hence:
f(x) = x³-18x²+101x-180 = (x-4)(x-5)(x-9)
the x-intercepts are x₁ = 4, x₂ = 5, x₃ = 9.
To find the y intercept plug x= 0 in f(x) = x³-18x²+101x-180
f(x) = y = -180 (y intercept
The graph starts from - ∞ to + ∞ and passes through one maximum and one minimum
Answer:
y=13x-105
Step-by-step explanation:
y-12=13(x-9)
y-12=13x-117
+12 +12
y=13x-105
Answer:
x=11
Step-by-step explanation:
M is the midpoint this means that we can set AM and BM equal to eachother, once this is done we can solve for x
9x-6=6x+27 (set equal to eachother)
9x=6x+33 (add 6)
3x=33 (subtract 6x)
x=11 (divide by 3)
