Answer:
y=5
Step-by-step explanation:
b-intercept is the same as y-intercept
80*t+70*t=50
t = .33 hours =20 minutes
This assumes the trains are going opposite directions (opposite tracks so I’m assuming opposite directions)
m<JAK=3x
m<JAK=180-90-30=60
m<LAF=m<JAK=60
60+5x+3x=180
8x=120
x=15
m<JAH=3x=3(15)=45 degrees
answer: 45 degrees
Answer:5x - 6
Step-by-step explanation:
Answer:
C. (x-2)^2=7
Step-by-step explanation:
What you have to do first is to get rid of the 3 in the x^2 so you will divide 3 by the whole thing to get x^2-4x=3.
You will then divide -4 by 2 and then square the answer to get 4.
You will then add the 4 into the end of the equation and to the 3 to get x^2-4x+4=7.
You will then make into a perfect square (x-2)^2=7 and that is your answer.
