PLZ HLP ME I BEG!!! 13 POINTS 1. During a trip, Amy had to take two different trains. Her first train traveled for 3hrs and the
second train traveled for 4hrs Combined, the trains traveled 625 miles If the equation 3m + 4n = 625 represents this situation, which statements are true regarding this equation? select two that apply a. The variable m in the equation represents the speed of the second train. b. The variable n in the equation represents the speed of the first train. c. The variable m in the equation represents the speed of the first train. d. The variable n in the equation represents the number of hours Amy traveled on the second train. e. The variable m in the equation represents the number of hours Amy traveled on the first train. f. The variable n in the equation represents the speed of the second train. 2. What is the point-slope form of the equation for the line with a slope of −2 that passes through the point (4,−6)? a. y+6=−2(x−4) b. y−4=−2(x+6) c. y=−2x−6 d. y−6=−2(x+4) 3. Examine the following table that represents some points on a line. x | -6, -4, 6 y | -10, -9, -4 Which equations in point-slope form represent this line? Select all that apply. a. y+9=1/2(x+4) b. y+4=1/2(x−6) c. y+10=1/2(x+6) d. y+10=2(x+6) e. y+4=2(x−6) f. y−9=2(x−4)
Given that cos θ=3/5 , the value for tan θ will be obtain as follows: cos θ=adjacent/ hypotenuse thus from the information: adjacent=3 hypotenuse=5 to obtain the opposite we use Pythagorean theorem, c^2=a^2+b^2 plugging in the values we get: 5^2=a^2+3^2 a^2=5^2-3^2 a^2=25-9=16 a=4 thus tan θ=opposite/ adjacent=4/3
