Large box 70, small 55
x+y=125
40x+20y=3900
y=125-x
40x+20(125-x)=3900
40x+2500-20x=3900
20x=1400
x=70
125-70=y
y=55

Which of the following equations is on the same path as x=2-3t, y=7-6t?
Svet_ta [14]

Answer:

C. y = 3+2\cdot x

Step-by-step explanation:

Let be the parametric equations x = 2-3\cdot t and y = 7 - 6\cdot t, we need to clear t and eliminate it afterwards to obtain a function of the form y = f(x):

x = 2 - 3\cdot t

3\cdot t = 2 - x

t = \frac{2}{3}-\frac{1}{3}\cdot x (1)

y = 7 - 6\cdot t

6\cdot t = 7 - y

t = \frac{7}{6} - \frac{1}{6}\cdot y (2)

By (1) and (2):

\frac{2}{3}-\frac{1}{3}\cdot x = \frac{7}{6}-\frac{1}{6}\cdot y

4 -2\cdot x = 7 - y

y = 3+2\cdot x

Hence, the correct answer is C.
