-3(s-1) + 5s
we are going to distribute the -3 through the parenthesis...all that means is multiply -3 by everything in the parenthesis.
-3 * s + (-3)* -1 + 5s
-3s + 3 + 5s...now we combine like terms
-3s + 5s + 3 =
2s + 3
Answer:
x = 3.6
Step-by-step explanation:
3/5 = x/6
multiply both sides by 6
18/5 = x
as a decimal
x = 3.6
Answer:
y = 3x + 2
Step-by-step explanation:
Convert the equation to slope intercept form to get y = –1/3x + 2. The old slope is –1/3 and the new slope is 3. Perpendicular slopes must be opposite reciprocals of each other: m1 * m2 = –1
With the new slope, use the slope intercept form and the point to calculate the intercept: y = mx + b or 5 = 3(1) + b, so b = 2
So y = 3x + 2
Answer:
hello : x = 2
Step-by-step explanation:
note : a^3 = b^3 : a=b
x^3-8=0
x^3=8
x^3= 2^3
so : x=2
Answer:
Z-score = 1.18
Step-by-step explanation:
The z-score measures how many standard deviations from the mean a data is
Therefore the z score is the quotient between the difference between a value and the mean and the standard deviation
Where
μ is the mean, x is a data of the population and 
is the standard deviation
In this case
Then the z-score is
