Answer:
y=1.6x+7.2
Step-by-step explanation:
First you want to find m or the slope so use the formula m=y2-y1/x2-x1 and you get your slope which is 1.6.
Then you plug in your slope to the equation including another coordinate or example (3,12) plugged in to make 12=1.6(3)+b. Now you can solve for b.
Once you do that you get b=7.2
So now with m=1.6 and b=7.2, you can finally make the equation.
y=1.6x+7.2
Answer:
x = 36
Step-by-step explanation:
The angles 3x - y and 2x + y form a straight angle and are supplementary, so
3x - y + 2x + y = 180
5x = 180 ( divide both sides by 5 )
x = 36
-----------------------------------------------
5y and 3x - y are vertical angles and congruent, hence
5y = 3x - y ( add y to both sides )
6y = 3x ← substitute x = 36
6y = 3 × 36 = 108 ( divide both sides by 6 )
y = 18
Answer: S = 20 lbs L = 45 lbs. Both answer have been rounded from below
Step-by-step explanation:
L+S = 65 lbs
55L + 65S = 3774 lbs
55L+55S = (65)(55) = 3,575 lbs
10S = 199 lbs
S = 19.99 (round to 20)
L + S = 65
L + 19.99 = 65
L = 45.01 (round to 45)
