Answer:

y = 2x + 11, if you're supposed to convert to y = mx + b

Approach by 2 formulas; slope m= (y2-y1)/(x2-x1) and the

equation of the line is (y-y1)= m*(x-x1) where point 1 is (x1,y1)

and point 2 is (x2,y2)

What is the area of the pool and the area of the pool and the walkway? Show your work.

andrew11 [14]

Answer:

Part a) The area of the pool is $320\ m^{2}$

Part b) The area of the pool and the walkway is $520\ m^{2}$

Step-by-step explanation:

we know that

The area of the rectangle is equal to

$A=LW$

where

L is the length side

W is the width side

Part a) What is the area of the pool?

we have

$L=20\ m$

$W=16\ m$

substitute the values

$A=(20)(16)=320\ m^{2}$

Part b) What is the area of the pool and the walkway?

we have

$L=26\ m$

$W=22\ m$

substitute the values

$A=(26)(22)=520\ m^{2}$

Use point-slope form to write the equation of the line in slope-intercept form that passes through the points (0, -5) and (-3, 4

Anna007 [38]

The point slope form of this line is y+5=m(x). Now, you need to find m (the slope) of the line using the formula (y1-y2)/(x1-x2):

(-5-4)/(0--3)

-9/3

-3

The complete point slope formula is: y+5=-3x.

Now, to fin the slope intercept form, just solve for y:

y+5=-3x

<em>*Subtract 5 from both sides*</em>

y=-3x-5

Hope this helps!!

Write the following expression as a fraction in lowest terms:

alukav5142 [94]

Step-by-step explanation:

$\[2 + \cfrac{2}{2 + \cfrac{3}{3 + \cfrac{4}{4 + 5}}}\]=$

$\[2 + \cfrac{2}{2 + \cfrac{3}{3 + \cfrac{4}{9}}}\]=$

$\[2 + \cfrac{2}{2 + \cfrac{3}{\cfrac{31}{9}}}\]=$

$\[2 + \cfrac{2}{2 + \cfrac{27}{31} }}}\]=$

$\[2 + \cfrac{2}{ \cfrac{62+27}{31} }}}\]=$

$\[2 + \cfrac{2}{ \cfrac{89}{31} }}}\]=$

$\[2 + \cfrac{62}{{89} }}}\]=$

$2 \cfrac{62}{{89} }}}$

Y=5x-4y = 5 x − 4<br><br> y=-x+2

Nadya [2.5K]

Answer:

Y= x+2 " substituting value of y

Step-by-step explanation:

Y=5x-4y = 5x - 4

or, 5x - 4(x+2) = 5x - 4

or, 5x - 4x+ 8 = 5x-4

or, x +8 = 5x - 4

or, 0= 5x - x - 4-8

or, 0= 4x - 12
