Answer: 104.375 (104 if you need it rounded)
Step-by-step explanation: So the question here is only asking for one angle, so you take the sum of all of the angles (835) and divide it by the total amount of sides (8). and you have your answer.
Answer:
y= 3x - 15
Step-by-step explanation:
parallel lines have the same slope, but different y intercepts
Answer:
Functions: y = -x + 11, y = 2x^2 - 6x + 4, y = 7
Not Functions: x = 3, x^2 + y^2 = 81, y^2 = -5x - 12
Answer:
77 degrees
Step-by-step explanation:
You have to study
Answer:
The x-value is between 2 and 3, and the y-value is between –4 and –5.
Step-by-step explanation:
The system of equations y = (1/4)x - 5 and y = -(1/2)x - 3.
The solution of the equation is the point of intersection of the two lines, from the graph, the intersection of the red and blue lines which represent the equation of the lines has an x-value is between 2 and 3, and the y-value is between –4 and –5.
Also the solution of the equation can be solved by solving the two equations simultaneously:
y = (1/4)x - 5 . . . 1)
y = -(1/2)x - 3 . . . 2)
Subtracting equation 2 from 1:
0 = (3/4)x - 2
(3/4)x = 2
x = 2 × 4/3
x = 8/3 = 2.67
x = 2.67
To find y put x = 2.67 in equation 1:
y = (1/4)(8/3) - 5
y = 8/12 - 5
y = -13/3
y = -4.33
