Answer:
y= -3/5 x -7.2
Step-by-step explanation:
-6 = 6/5 + b
b= - 7.2
Answer: x=3 and y=−2
Step-by-step explanation:
x=−2y−1;4x−4y=20
Step: Solve x=−2y−1 for x:
Step: Substitute−2y−1 for x in 4x−4y=20:
4x−4y=20
4(−2y−1)−4y=20
−12y−4=20(Simplify both sides of the equation)
−12y−4+4=20+4(Add 4 to both sides)
−12y=24
−12y
−12
=
24
−12
(Divide both sides by -12)
y=−2
Step: Substitute−2 for y x=−2y−1:
x=−2y−1
x=(−2)(−2)−1
x=3(Simplify both sides of the equation)
Answer:
<h2><em><u>62</u></em></h2>
Step-by-step explanation:
<em>Here</em><em>,</em>
x + 118 = 180. <em>[</em><em>Since</em><em> </em><em>Supplementary</em><em> </em><em>Angle</em><em>]</em>
=> x = 180 - 118
=> <em><u>x = 62 (Ans)</u></em>
