Answer:
2x-5=y
I'm not sure how your graphing tool works so I'll give you five or so coordinates
(-1,-7)
(1,-3)
(0,-5)
(2,-1)
(-2,-9)
Step-by-step explanation:
You first need to write an equation that you can graph
Knowing that the slope is two we can write the following equation
2x+b=y
We also know that when x=1 y=-3
This gives us 2*1+b=-3
which means that 2+b=-3
subtract 2 from both sides to figure out the b=-3
This means that the line you have to graph is 2x-5=y
Answer:
x=5
Step-by-step explanation:
Well all i did was guess a random number from 1-10 so I could see what numbers make the equation bigger than -18 and the fist thing I guessed was 5 so this is what I did
8-6*5=-22
And them I said let me see if any multiples equal -18 so I went to for and did this
8-6*4=-16
That's when I guessed the answer if i looked at the sign correctly!
Given:
population mean, μ =135
population standard deviation, σ = 15
sample size, n = 19
Assume a large population, say > 100,
we can reasonably assume a normal distribution, and a relatively small sample.
The use of the generally simpler formula is justified.
Estimate of sample mean
Estimate of sample standard deviation
to 5 decimal places.
Thus, using the normal probability table,
Therefore
The probability that the mean weight is between 125 and 130 lbs
P(125<X<130)=0.0731166-0.0018308
=
0.0712858

Step-by-step explanation:
The rationalizing factor of 
is 
Step-by-step explanation:
-3-4 -32x=3×8x
-3-4-32x=24x
-6=32x+24x
-6=56x
:. x=-28/3
