N equation of a line through (0, 2) which is perpendicular to the line y=3x+3y=3x+3 has slope
zhannawk [14.2K]
Something's not quite right here.  What do you mean by "N?"

I could and will make assumptions regarding what you meant.  (Feel free to correct me if need be.)

Find the equation of a line through (0,2) <span>which is perpendicular to the line y=3x+3.  To find the slope of this perpendicular line, take the negative reciprocal of 3 (the slope of the given line).  It is -1/3.

Using the point-slope form of the equation of a straight line:

y = (-1/3)x + 2 (answer)</span>

The statue of Liberty stands on a 150 ft. pedestal. From a point 250 ft. from the base of the
bekas [8.4K]

Answer:

148ft

Step-by-step explanation:

To solve this question, you'll have to imagine the statue makes a right angle triangle with the base since it has an angle of elevation from the base to the top of the torch.

Assuming the height from the pedestal to the top of the torch is y

The height of the statue is x

But we know the height of the pedestal = 150ft

The distance from the observer to the base of the pedestal = 250ft

And the angle of elevation = 50°

See attached document for better illustration.

Tanθ = opposite / adjacent

θ = 50°

Adjacent = 250

Opposite = y

Tan50 = t / 250

y = 50 × tan50

y = 50 × tan50

y = 50 × 1.1917

y = 297.925ft

The height of the statue from the base of the pedestal to the top of the torch is 297.925ft

The height of the statue = x

x = (height of the statue + height of the pedestal) - height of the pedestal

x = y - 150

x = 297.925 - 150

x = 147.925ft

Approximately 148ft

The height of the statue is 148ft

What is the value of x when y equals 2 in the equation y equals x over 4 - 7
Alex

The value of x when y = 2 is x = 36

Step-by-step explanation:

The equation that we have in this problem is:

y=\frac{x}{4}-7

In order to find the value of x when y is equal to

y = 2

We need to re-arrange the equation making x the subject.

We proceed as follows:

1) We add +7 on both sides:

y+7=\frac{x}{4}-7+7\\y+7=\frac{x}{4}

2) Now we multiply both  sides by 4:

4(y+7)=\frac{x}{4}\cdot 4\\x=4(y+7)

3) Now we can substitute y = 2 and find the value of x:

x=4(2+7)=4(9)=36
