Answer:
(4,-4)
Step-by-step explanation:
3*(6x+5y=4)
18x+15y=12
-) 18x – 4y = 88
19y = -76
y=-4
plug back into first equation
6x + 5(-4) = 4
6x = 4+20
x=4
Answer:
An equation is
.
Step-by-step explanation:
☆Since since we're given the slope, all we need to do is find the y-intercept.
☆The slope-intercept formula is: y = mx + b.
☆We are going to plug in according to the formula.
☆We have everything we need, so now we put it together.
Answer:
non sampling error
Step-by-step explanation:
Sampling error in a statistical analysis arising from the unrepresentativeness of the sample taken.
Non Sampling error is a term used in statistics that refers to an error that occurs during data collection, causing the data to differ from the true values.
You form both equations into one equation and solve for x. Then you would add in the value and solve. The like PQS is equal to 180 degrees. You would first do (3x-5) + (x+1) = 180.
