Answer:
A = 3
B = -5
C = 1
C = -6
Step-by-step explanation:
Factors of 30:
10 3
15 2
5 6
Using positives or negatives of these numbers you need to find two that'll satisfy the equation
A is known to be 3 and C is known to be 1 because the factors of 3 are only 1 and 3.
After some trial and error we end up with
(3x-5)(x-6)
We know this will work because hen you multiply it out you get
3x^2-18x-5x+30
simplify
3x^2 -23x + 30
And this is the original equation
11: 14 and 20, continued
0.173 to nearest hundredth: 0.17
7.09 <7.99
3/4 longer
numerical expression: 13
2430 divided by 5: 486
980 divided by 1000= 0.98
162 x 78=12636
Fifty-three hundredths: .53
That's all I'll do for now :)
Your welcome!
Good luck!
Answer:
Step-by-step explanation:
The confidence interval for population mean is given by :-
Given : Sample mean : hours
Standard deviation hours
Sample size : n=90, which is a large sample(n<30), so we use z-test.
Significance level:
Critical value :
Then , the confidence interval for population mean will be :-
Hence, the 90% confidence interval for the mean life of all light bulbs of this type. is
Answer: A(0,-2) B(2,-2) and C(0,-7)
Step-by-step explanation: So the question is asking you to figure out where the shape will be after a translation of four units to the right and 6 units down. So starting with A, you count right four, and then you count down 6. Same thing with B and C. (Hope this helped!)
Answer:
Just change the b value so it is lower than it already is in y = mx + b so . . .
y = 3x + 1
y = 3x - 10000
y = 3x - 1000000000000000000000000000000000000
I think you get it now. lol
