Y - y 0 = m ( x - x 0 )
x 0 = 6, y 0 = -3, m = 1/2
The point-slope form of the equation is:
y + 3 = 1/2 ( x - 6 )
Okay so triangle DEA = 71 degrees
And angle DEB = 90 degrees (right angle)
90 - 71 = 19 degrees
Angle EBA = 90 degrees (right angle)
That leaves the 90 degrees + 19 degrees = 109 degrees
There’s 180 degrees in a triangle so
180 - 109 = 71 degrees
Answer:
Comelia is correct.
Step-by-step explanation:
Rational numbers are those whole can be represented as a fraction.
=> Every fraction is a rational number.
Comelia Says:
All Whole Numbers are Rational Numbers
=> Example: 3 = rational number
=> 3 can be represented as a fraction
=> 30/10 = 300/100
So, Comelia's statement is correct.
Christopher Says:
All Rational Numbers are Whole Numbers
=> Example: 1/2 = Whole Number
=> 1/2 is a fraction
=> 1/2 = .5
=> .5 is not a whole number.
Whole numbers don't have numbers after the decimal point.
So, Christopher's statement is incorrect.
9.68x + 21.6 - 6.23x = 2.3x + 17
Combine like terms on the left side:
3.45x + 21.6 = 2.3x + 17
Subtract 2.3x from both sides:
1.15x + 21.6 = 17
Subtract 21.6 from both sides:
1.15x = -4.6
Divide both sides by 1.15:
X = -4
