I believe the value of x would be 20.
Answer: D. Arabella. She has a 0.79 probability of brushing both times.
Step-by-step explanation:
A.P.E.X
The equations are,
3x + y = 8 ——— 1
4x - 2y = 3 ——— 2
Multiply equation 1 by 2
Which gives,
6x + 2y = 16 ——— 3
Now , add equation 2 and equation 3
Which gives,
10x = 19
From there , x = 19/10
Therefore x = 1.9
Now substitute x = 1.9 in the equation 1
So the equation becomes ,
3*1.9 + y = 8
From that ,
y = 8 - 5.7
Therefore , y = 2.3
So , x = 1.9 and y = 2.3.
Okay?

Answer:
Step-by-step explanation:
The smallest zero is x=-7 with multiplicity of 1
The middle zero is x=2 with the multiplicity of 2
The largest zero is x=0 with the multiplicity of 7.
So, basically you just find the zero for each of the terms by setting em equal to 0 and then the multiplicty of it is the exponent for that particular term!
Hope this helps!
