Product of two and a number x can be written as 2*x or simply 2x.
Now the sum of eight and the product of two and a number x can be represent as an algebraic expression 8+2x.
Answer:
[2, 15]
Step-by-step explanation:
The graph shows the n/4 algorithm to be better (smaller run time) for n in the range 2 to 15.
Answer:
Step-by-step explanation:
If I'm not mistaken you're looking for an equation, if not then comment below...
y = 8s + 16p
Since there's 8 of them, they'll get 8 sodas total and 16 sliced of pizza total.
X intercepts are where the y value is 0. So, set y=0 and solve
0=x^2-9x+18
0=(x-6)(x-3)
x=6,3
The x intercepts are (6,0) and (3,0)
if you want to check, try these (x, y) pairs in the original equation.
P( both allergic) = 0.17*0.17 = 0.0289
P(at least one is allergic) = 1 - P(neither are allergic) = 1 - 0.83^2 = 0.311
