4x^5 is the term with a 5th degree. the coefficient is 4.
Look at the picture.
ΔZYX and ΔDYC are similar. Therefore the lengths of sides are in proportion:
DC = x
ZX = 16
DY = a
ZY = a + a = 2a
Substitute:
<em>multiply both sides by 16</em>
<h3>Answer: CD = 8</h3>
8x + 2x
Plug the variable in.
8×6 + 2×6
48+12 = 60
The two angles are corresponding angles, which means they are equal to each other. Make them equal to each other in an equation.
11x - 2 = 130
Add 2 to both sides.
11x = 132
Divide both sides by 11.
x = 12
Vertical line (when y = 0)
⇒ Equation : x = -1
Horizontal line (when x = 0)
⇒ Equation : y = -8
