<span>m = j + 16
m + 5 = 3j
---
put the system of linear equations into standard form
---
m - j = 16
m - 3j = -5
---
x - y = 16
x - 3y = -5
so now that you have your equations formed, just solve.
x - y = 16 , which means that x = y + 16
substitute for x in the second equation :

Remember that the slope intercept formula is:
y = mx + b
m is the slope
b is the y-intercept
Let's first find the slope. Below is how you find the slope using two points:
The formula for slope is
In this case we have the two points:
(-1, -5) and (-3, -7)
This means that:
^^^Plug these numbers into the formula for slope...

1
^^^This is your slope
This is the formula we have so far:
y = 1x + b
OR
y = x + b
Now we must find b
To do that you must plug in one of the given points the line goes through in the x and y of the equation.
(-1, -5)
-5 = 1(-1) + b
-5 = -1 + b
-4 = b
(D) y = x - 4
Hope this helped!

Answer:
The slope is -2/9
Step-by-step explanation:
9y + 2x = 54
Solve for y to get the equation in the form
y = mx+b where m is the slope and b is the y intercept
Subtract 2x from each side
9y + 2x -2x = -2x+54
9y = -2x+54
Divide by 9
9y/9 = -2x/9 + 54/9
y = -2/9 x +6
The slope is -2/9
Parallel lines have the same slope
Answer:
All real numbers except x cannot equal 10.
Step-by-step explanation: the denominator can not equal to zero that is undefined.
Answer:
There is enough evidence to make the conclusion that the population mean amount of time to assemble the Meat Man barbecue is not equal to 10 minutes (P-value=0.009).
Step-by-step explanation:
We have to perform an hypothesis test on the mean.
The null and alternative hypothesis are:

The significance level is
.
The test statistic t can be calculated as:

The degrees of freedom are:

The P-value (two-tailed test) for t=2.737 and df=49 is P=0.00862.
This P-value (0.009) is smaller than the significance level, so the effect is significant. The null hypothesis is rejected.
There is enough evidence to make the conclusion that the population mean amount of time to assemble the Meat Man barbecue is not equal to 10 minutes.
