A rectangle as an area of 240 square ft the base is 15 what is the height of the rectangle
zhannawk [14.2K]

Answer:

16 ft

Step-by-step explanation:

Hi there,

The formula for the area of a rectangle is A = b*h.

So, let's start out by plugging in what we know.

240 = 15h

Now, solve for h by dividing both sides by 15

h = 16

So, the height of the rectangle is 16 ft

Hope this helps! Stay safe!

Use the given functions to find f (g(x)), and give the restrictions on x.
torisob [31]

Answer:

f(g(x)) = \frac{10x-9}{3 + 3x}

Step-by-step explanation:

Given

f(x) = \frac{1}{x} - 3

g(x) = \frac{3}{x} + 3

Required

Find f(g(x))

If: f(x) = \frac{1}{x} - 3

Then:

f(g(x)) = \frac{1}{3/x + 3} -3

Solve the denominator (take LCM)

f(g(x)) = \frac{1}{\frac{3+3x}{x}} -3

f(g(x)) = \frac{x}{3 + 3x} - 3

It can be solved further as:

f(g(x)) = \frac{x-3(3 + 3x)}{3 + 3x}

f(g(x)) = \frac{x-9 + 9x}{3 + 3x}

f(g(x)) = \frac{10x-9}{3 + 3x}

Which point lies on the line with point-slope equation y - 3 = 4(x + 7)?
Sav [38]

Answer:

y=4x+31

your answer will have a line that

3 is your y-intercept located at your y-axis

and 4x your slope.

we start from our point on the y-axis 31

and rise/run

rise over run = 4/1

rise 4

run 1

so move up 4

and to the right 1

Step-by-step explanation:

Since there is no image for me to tell you which line it is you can easily find out by chancing this expression to y=mx+b form. also known as slope intercept form.

y-3=4(x+7)

we want to do order of operations. pemdas

so first we do Parenthesis to do so we need to distribute the 4.

after we do so we get...

y-3=4x+28

now we need to move -3 to isolate y

to do so we need add 3

y=4x+31
