Plane because it doesn’t stop extending and does not go down, think of a piece of paper.

A):      

x5 ==>      4 boxes  =   3ft   <==== x5

20 boxes   =       ?  ft

20 boxes  is    15 ft. high



B):   x3  ===>   4 boxes     =    3ft.  <==== x3

   ?   boxes           =          9ft.

       12 boxes  will fit in one stack.



c):  CL.143

 Perimeter  =     15  +  29  +  9  +  11  +  6  +  18   =====>  88m

A1    =    b  *   h

(18)(15)  

270m^2


A2    =   b  *  h

(11)(9)

99

Total  Area ======>   270    +    99   ======>  369m^2









CL.1-144

1/4    +   1/4   +   1/5     =    5/20    +   5/20   +   4/20    ====>    14/20

1/4  *    5/5  =====>  5/20

1/5   *    4/4    =====>  4/20

14/20      +      ?/20       =      20/20

?      =       6  Missing    Section

6/20      ======>     3/10

0.4            ========>    40%



B):    1/6  ======>   .00000

0.16 (Repeating 6)  ======>  16.6%



C):   37.5/100     =    375/1000     =======>     3/8

0.375      =========>   37.5%





CL-1.146

ADD:   1/6   +   1/2   show all steps:

Help me with these 3 questions, please
Zina [86]

Answer:

1. x = -4y ---> y = (-1/4)x

slope = -1/4. y-intercept = (0,0)

2. y = -2x + 4

3. y = (1/3)x - 1

Step-by-step explanation:

1. Re-write your equation so that x is on the right and y is on the left:

x = -4y ---> y = (-1/4)x

slope = -1/4. y-intercept = (0,0)

2. y-intercept = (0,4) ----> P1

x-intercrpt = (2,0) ----> P2

slope m = (y2 - y1) / (x2 - x1)

= (0 - 4)/(2 - 0)

= -2

therefore, y - y1 = mx - x1 ---> y - 4 = -2x

or y = -2x + 4

3. y-intercept = (0,-1)

x-intercept = (3,0)

m = (0 - (-1)) / (3 -0) = 1/3

y - (-1) = (1/3)x - 0 ---> y = (1/3)x - 1
