Two angles are supplementary if they add up to 180 degrees.
We have then:
m ∠ DAB + m ∠ ABC = 180
Substituting:
(85 - 2x) + (90 + x) = 180
From here, we clear the value of x:
-x + 175 = 180
x = 175 - 180
x = - 5
Let's try now that it is a parallelogram.
The opposite angles of a parallelogram are equal in measure:
m ∠ DAB = m ∠ BCD
85 - 2x = 80 - 3x
85 - 2 (-5) = 80 - 3 (-5)
85 + 10 = 80 +15
95 = 95
Answer:
x = -5
m ∠ DAB = m ∠ BCD (It is shown to be a parallelogram)
The straight line is a polynomial. ALL polynomials have real numbers as its domain.
The exponential functions f(x) and g(x) both have the form b^x or b^(-x). Both these exponential functions have a real domain, but the range of both are limited to strictly positive numbers.
Passes through (-2, -1) & slope=4/13
Standard form : Ax+Bx=C
However, we are going to use slope-intercept form to figure this out.
Slope-intercept form : y=mx+b where m=slope, b=y-intercept.
Simply plug everything in :)
y = 4/13x - 1
*Remember! In Standard Form, x and y are on the same side.
So, we must subtract 4/13x from both sides.
-4/13x + y = -1 ← Standard Form
