Answer:
Value of x is used to consider unknown value. The letter “x” is commonly used in algebra to indicate an unknown value. It is referred to as a “variable” or, in some cases, a “unknown.” In x + 2 = 7, x is a variable. ... A variable need not be “x,” but might be “y,” "w," or any other letter, name, or symbol.
Answer:
y is the same as 1y. so 9y + 1y = 10y
Answer:

Step-by-step explanation:
The equation of a line in the point-slope form:


We have:

Substitute:

Answer:
Step-by-step explanation:
To be able to draw a conclusion from the data given, lets find out the p value using the t score and this will be used to make a conclusion.
If the p value is less than 0.05 then, we will reject the null but if otherwise we will fail to reject the null.
Using a p value calculator with a t score of 2.83, significance level 0.05 and the test is a two tailed test, the p value is 0.004655 which is less than 0.05 and the result is significant.
This we will reject the null hypothesis H0:p∗=1/2 for this data set.
Answer:
x = 1/2 or 0.5
Step-by-step explanation:
Subtract 2 from both sides of the equation
x + 2 - 2 = 5x -2
Simplify
x = 5x -2
Subtract 5x from both sides of the equation
x = 5x -2
x - 5x = 5x - 2 - 5x
Solution
x = 1/2
