Answer:
c. (1,-2)
Step-by-step explanation:
by adding them together you can cancel out the y's and solve for x. once you get x, you can plug it into either equation and get y.
hope this helped :)
Answer:
131°
Step-by-step explanation:
Since KNJ is a straight line,
∡KNM +∡MNJ= 180° (adj. ∡s on a str. line)
(8x -5)° +(4x -19)°= 180°
<em>Simplify:</em>
12x -24= 180
<em>+</em><em>2</em><em>4</em><em> </em><em>on </em><em>both </em><em>sides</em><em>:</em>
12x= 180 +24
12x= 204
<em>Divide</em><em> </em><em>both </em><em>sides </em><em>by </em><em>1</em><em>2</em><em>:</em>
x= 204 ÷12
x= 17
∡KNM
= (8x -5)°
= [8(17) -5]°
= (136 -5)°
= 131°
Step-by-step explanation:
4(3x-1)=9-x
12x-4=9-x
12x+x=9+4
13x=13
x=13/13
x=1
Answer: the distance would be 75 mi
Answer:
-56-7k
Step-by-step explanation:
=> -7(8+k)
Expanding brackets using distributive property
=> (-7*8) + (-7*k)
=> -56 + (-7k)
=> -56-7k
