Answer:
x = 52/9
Step-by-step explanation:
The exterior angle is half the difference of the intercepted arcs, so we have ...
9x -5 = (158 -64)/2
9x = 52 . . . . . . . . . . . add 5
x = 52/9 = 5 7/9
Answer:
x1 = t, x2 = -t and x3 = 0
Step-by-step explanation:
Given the system of equation
x1 + x2 + x3 = 0 .... 1
x1 + x2 + 9x3 = 0 .... 2
Subtract both equation
x3 - 9x3 = 0
-8x3 = 0
x3 = 0
Substitute x3 = 0 into equation 1
x1 + x2 + 0 = 0
x1+x2 = 0
x1 = -x2
Let t = x1
t = -x2
x2 = -t
Hence x1 = t, x2 = -t and x3 = 0
Answer:
O x = 2
Step-by-step explanation:
Only x-intercepts will make the line horizontally and x = 2 is the line that passes through the point (2, 10)
Answer:
7. b
8. a
Step-by-step explanation:
The answer is A because both numbers can be divided by 6 to get 5 : 9
