5x+4=114
5x= 110
X=22
114+ 3(22)-24=156
180-156=24
2y=24
Y=12
Answer:
Height = 21.78 ft
Step-by-step explanation:
Tan θ = opposite / Adjacent
tan 40 = opposite / 20
where opposite is the part of the traffic light
0.839 × 20 = opposite
opposite = 16.78 ft
Now the total height of traffic light = 16.78 ft +5 ft
Total Height = 21.78 ft
1. no because 2x+10 is not equal to 2x+7
2. no. you cant add una like terms so 4x+4 doesn’t equal 8x
3. yes. the terms still retain their same value although they are not in the same order
4. yes. when u distribute the -3, you get -3x-6 which is of course equal to -3x-6
400,246 ( 200,200-77=200,123 divide by .5= 400,246
I hope this helps you
slope=y2-y1/x2-x1
slope=2-(-1)/1-2
slope=3/-1
slope= -3
