3x - 4y = 6 and 5x + 8y = -1

1.    slope:3/4

         y-int: (0,-3,2)

2.         slope: -5/8

                y-int: (0,-1/8)

Step-by-step explanation:

Point Form: (1,−3/4)

Equation Form: x=1, y= −3/4

Step-by-step explanation:

Solve for x in the first equation.

x=2+4y/3

5x+8y=−1

Replace all occurrences of x with 2+4y/3 in each equation.

10+44y/3=−1

x=2+4y/3

Solve for y in the first equation.

y=−3/4

x=2+4y/3

Replace all occurrences of y with −3/4 in each equation.

x=1

y=−3/4

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

0.32
