The answer is 15 because absolute deviation means a number of units a certain number is for 0. So, both 15 and -15 would have an absolute deviation of 15 because both numbers are 15 units away from 0. Hope I helped! Please rate me the Brainliest!
Answer:
A
Step-by-step explanation:
Answer:
Given system of equations:
To solve by substitution, equate the equations and solve for x:
Therefore, the x-values of the solution are 
and 
.
To find the y-values of the solution, substitute the found values of x into the functions:
Therefore, the solutions to the given system of equations are:
and 
Answer: True
The reason why this is true is because the opposite angles add up to 180 degrees
120+60 = 180
90+90 = 180
With any inscribed quadrilateral in a circle, the opposite angles must be supplementary (i.e. add to 180 degrees)
Answer:
x=7
Step-by-step explanation:
- 4(x-2) = 2x+3(x-5)
- 4x-8 = 2x+3x-15
- 4x-8 = 5x -15
- -x = -7
- x = 7
