Answer:
A= y= -2x+7.
B= y= -x+ 6
Step-by-step explanation:
The linear equation is y=mx+b
A= y= -2x+7.
-2 represents he slope and 7 represents the y intercept.
B= y= -x+ 6
- is the slop and 6 is the y intercept.
Hope this helps :)
Answer:
147.5 km and 64.4 km
Step-by-step explanation:
a=120 km
b=70 km
β=28 degrees ( ∘)
b^2=(a^2)+(c^2)−2ac*cosβ
70^2 =(120^2 )+(c^2)−2⋅ 120⋅ c⋅ cos(28∘ )
(c^2 ) −211.907c+9500=0
note p, q, and r are replacement variables in the Pythagorean theorem since a, b, and c are already in use
p=1;q=−211.907;r=9500
D=(q^2 ) −4pr=(211.907^2 )−4⋅1⋅9500=6904.75561996
