Write the equation of the line in
Brut [27]

Answer:

y - 3= 2(x - 0)  

Step-by-step explanation:

hello :

note 1 :

the point-slope formula is :

y - y_1 = m(x - x_1)   the point is A(x_1  , y_1 )  , m :  the slope

note 2 :

the slope is :   m = (y_2 - y_1)/(x_2 -x_1)  when given two points  :

A(x_1  , y_1 )  and  B(x_2  , y_2 )

in this exercice :  x_1 =0      y_1 =3            x_2 =1      y_2 =1

calculate now   m = (1 - 3)/(1 -0) =-2

an equation  in point-slope form is : y - y_1 = m(x - x_1)  

y - 3= 2(x - 0)

Joe made a scale drawing of the community pool in his town. the pool has a perimeter of 77 meters, what is the length and width
viva [34]

Answer:

The length of the pool is 28 meters and the width of the pool is 10.5 meters.

Step-by-step explanation:

In the scale drawing of Joe, the community pool has (length : width) = 8 : 3

Let the actual length of the pool is 8x meters and the actual width is 3x meters.

Now, given that the actual pool has a perimeter of 77 meters.

So, 2(8x + 3x) = 77

⇒ 22x = 77

⇒ x = 3.5

So, the length of the pool is 8x = 8(3.5) = 28 meters and the width of the pool is 3x = 3(3.5) = 10.5 meters. (Answer)

Find the value of f(3) for the function.<br> f(x) = -2(x + 3)
BabaBlast [244]

Answer:

-2(3+3) = -12

Step-by-step explanation:

f(x) is telling you to substitute all the x values into the equation. The f(x) of the function is 3, telling you to plug in 3 in the equation. This leads to -2(6) = -12.
