Kimm since the function is g(x) = 3(x-2) and we are given g(x)=6 That means: 6 = 3(x-2) Then we need to know what is x? 6 = 3x - 6 (distribute the 3) 12 = 3x (add 6 to both sides) 4 = x (divide both sides by 3)You can check it this way. Is g(4) = 3(4-2) = 6 ? 3*2 = 6
Answer:
(4,2)
Step-by-step explanation:
Answer:
H0: u ≥ 9.5
Ha: u < 9.5
Step-by-step explanation:
The null hypothesis and the alternate hypothesis are reverse of each other.
The claim is either set as the null or alternate hypothesis
The null hypothesis is : H0: u ≥ 9.5 the mean breaking strength of a ceramic insulator is at least 9.5 which is considered equivalent to the standard.
The alternate hypothesis is: Ha: u < 9.5 the mean breaking strength of a ceramic insulator is less than 9.5 which is not considered equivalent to the standard.
Let "the number" = x
3x - 6 = 45 is your equation
Solve for x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
Isolate the x. First, add 6 to both sides
3x - 6 (+6) = 45 (+6)
3x = 51
Isolate the x. Divide 3 from both sides
3x/3 = 51/3
x = 51/3
x = 17
17 is your answer for "a number".
hope this helps
