Just put 4 as x in the equation and solve it. The new equation is:
sqrt(2*4)+1+3 = 0
Now we can solve it.
sqrt(2*4) becomes sqrt8:
sqrt8+1+3=0. -------> sqrt8+4=0
The sqrt of 8 is about 2.83.. so 2.83+4 is:
6.83
So we have 6.83 as the answer
but 6.83 does not equal 0 so x cannot equal 4
Answer:
b. The slope is -10, and the y-intercept is 1.
Step-by-step explanation:
Y = slope(x) + y-intercept
P(A) =0.54
P(B)= 0.68
P'(A)= 1-0.54 = 0.46
P'(B)= 1- 0.68 = 0.32
The probability of neither of both event will occur:
= P'(A)×P'(B)
=0.46 × 0.32
=0.1472
