To get the mean, you add all of the numbers, and then divide the answer by the number of numbers.
15+(-6)= 9
9+12= 21
(21+x= q )⬅️ignore this for now, that's where the unknown number would have been
The mean = 5, and the number of numbers is 4, so basically, you find 5•4=20
So take the 21 from before, and if you add -1, you get 20!
So, x= ➖1⃣!!!!!!! (That's a -1)
Answer:
in the equation y=mx+b. The equation of the line that has a slope of 0 and a y-intercept of -8 is: y=-8.
Step-by-step explanation:
If the slope of a line is undefined, then the line is a vertical line, so it cannot be written in slope-intercept form, but it can be written in the form: x=a , where a is a constant. If the line has an undefined slope and passes through the point (2,3) , then the equation of the line is x=2 .
