Y = 2x + 1
y = 4x - 1

Step-by-step explanation: use mathway without the ""

x = 1

y = 3

Step-by-step explanation:

since they both equal y, you can set them equal to each other

2x + 1 = 4x - 1

subtract 2x from both sides to get the x's on one side

1 = 2x - 1

add one to both sides to get 2x by itself

2 = 2x

divide by 2 to get x by itself

x = 1

plug in 1 for x in either equation to solve for y

y = 2(1) + 1

y = 2 + 1

y = 3

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,
