3 + 1 2/4. = 4 1/2

3. 1 3/4 hours.

Please tell me the slope ontercept forn of this equation step by step 11x-4y=32

Afina-wow [57]

Answer:

Gradient is 11/4 and y intercept -8

Step-by-step explanation:

11X -4Y =32

transfer 11x on other side

-4y = -11x +32

multiply all termsby -1 so that coefficient of y is positive

4Y = 11X -32

DIVIDE ALL TERMS BY 4

Y = (11/4)X -8

COMPARE THIS WITH Y=mX +C

GRADIENT m is 11/4 and Y intercept C is -8

Gradient is 11/4 and y intercept -8

324 ft

The distance between the flagpole and the building is the number of feet between them

The building is 162 feet from the flagpole

<h3>How to determine the distance</h3>

The given parameters are:

Flagpole = 40 feet
Building Shadow = 324 feet

The flagpole's shadow is 50% longer than the flagpole.

So, the length (l) of the flagpole's shadow is:

$l = 40 * (1 + 50\%)$

$l = 60$

The length of the building's shadow (d) is then calculated as:

$60 : 40 =d : 324$

Express as fraction

$\frac{60}{40}= \frac{d}{324}$

$1.50 = \frac{d}{324}$

Solve for d

$d = 1.50 * 324$

$d = 486$

The distance (x) of the building from the flagpole is then calculated as:

$x = 486 - 324$

$x = 162$

Hence, the building is 162 feet from the flagpole
