Answer:
C) 12
Step-by-step explanation:
Absolute value always means it is the positive version of the number
This switches -7 to 7 and 5 stays the same.
5 + 7 = 12
Answer:
Its a linear function
Step-by-step explanation:
2 - 4 / 2 - 1
-2 / 1
-2
y - 2 = -2 ( x - 2 )
y -2 = -2x + 4
y = -2x + 6
Y - y1 = m(x - x1)
slope(m) = 3
(4,7)....x1 = 4 and y1 = 7
now we sub
y - 7 = 3(x - 4) <==
Let x be the page number then x+1 would be the other page number (because the pages are two facing pages which means they follow on consecutively)
Then
(x)(x+1) = 156
x^2 + x - 156 = 0
x = 12 or x = -13( but x can't be a negative number)
so x = 12
and the next page is 13
Question:
Which of the following is a quadrantal angle?
a) π/2 b) π/3 c) 2π/3 D) 4π/5
Answer:

Step-by-step explanation:
Required
Which of a to d is a quadrantal angle
An angle is said to be quadrantal if and only if the angle has its terminal side on the x or y axis.
Such angles (in degrees) are: 90, 180, 270, etc.
So, we have:

[Convert to degrees]


Hence:
is a quadrantal angle
