Answer:
y=-2x-5
Step-by-step explanation:
slope (m)= -2, point (-4,3) put in y=mx+B
3 (y)= -2 [m](-4) + B
3=-2 (-4)+B. - multiple -2 and -4
3= 8 +B. - two negatives. multipled gives you a positive
3=8+B. - subtract 8
-8 -8
-5=b
y= -2x-5
If your ratio is 1 : 50, then for every 1 ft of the model, you have 50 feet of actual church. Thus, if the model is 3.5 ft, then
1 / 50 = 3.5 / x
where x is the actual height of the church. Cross multiply and solve for x.
1 * x = 50 * 3.5
x = 175
Thus, the actual church is 175 ft
3/5x + 5 = 4/5
3/5x + 5 (-5) = 4/5 (-5)
3/5x = -4 1/5
3/5x/(5/3) = -4 1/5(/)(5/3)
x = (- 21/5)/ (5/3)
x = -21/5 x (3/5) (flip the signs by flipping the second fraction and the divide to a multiply)
x = -21/5 x 3/5
x = -63/25 or x = - 2.52
