Answer:

solution: x= 0.273, y= 1.909.

Step-by-step explanation:

  • given system of linear equations : x+3y=64x−6y=6
  • these can also be splitted or written individually as:

x+3y=6     &   64x−6y=6

  • the first equation can also be written as, y=2-\frac{x}{3}

so,  it is line with slope : -1/3 and y-intercept :2

  • the second equation can also be written as, y=\frac{32x}{3} -1

so,  it is line with slope : 32/3 and y-intercept :   -1

  • now we can easily draw graphs for these equations using the above interpretation.
  • graph is in the attachment.
  • so, the solution is:  x= 0.273, y= 1.909.

Answer:

w =< 70

(width is less or equal to 70 inches)

Step-by-step explanation:

Let l = length, w = width, h = height

Restrictions given in this question:

'sum of perimeter of the base and the height cannot exceed 130 inches'

perimeter of the base is 2 width and 2 length of the box

perimeter = 2w + 2l

Therefore, inequality involves here is

2w + 2l + h =< 130

(Note that =< here means less or equal)

Then a new condition given with

height, h = 60 in

and length is 2.5 times the width

l = 2.5w

Substitute this new condition into the equation will give us the following:

2w + 2(2.5w) + 60 =< 130

2w + 5w + 60 =< 130

7w + 60 =< 130

7w =< 130-60

7w =< 70

w =< 10

PLEASE HELP AND HURRY
kogti [31]

Here the given expression is

y =(\frac{3}{4})^x

We need to find the value of y when x =3 . So we substitute the value of x in the given expression.

y =(\frac{3}{4})^3 = \frac{27}{64} =0.4

So when x=3, y=0.4 and that's the required answer.
