For length BC, where B(0,3) and C(4,-1)
following the axis, length ranges from 0 to 4(according to xaxis) and 3 to -1(according to yaxis) thus 4-0=4,3-(-1)=4 will give u length of 4 for BC.

For length EC, where E(2,-3) and C(4,-1)
following the axis,length ranges from 2 to 4(according to xaxis) and -3 to -1(according to yaxis), thus 4-2=2,-1-(-3)=2 will give u length of 2 for EC.
(its 4-2 and -1-(-3) not 2-4 and -3-(-1) as length cannot be -ve)

For lengths BF and EF, since BF//EC, BF=2. Since EF//BC, EF=4

Thus 4+2+4+2= 12 units

Eight burgers and three orders of fries cost $79.49. Six orders of fries and twelve burgers cost $125.82.Find the price of one b
dezoksy [38]

Answer:

  • Burgers - $8.29 and fries - $4.39

Step-by-step explanation:

<u>Let burgers - b, fries - f</u>

  • 8b + 3f = 79.49
  • 12b + 6f = 125.82

<u>Double the first equation and subtract the second equation:</u>

  • 16b + 6f - 12b - 6f = 2(79.49) - 125.82
  • 4b = 33.16
  • b = 33.16/4
  • b = 8.29

<u>Find f:</u>

  • 8(8.29) + 3f = 79.49
  • 3f = 79.49 - 66.32
  • 3f = 13.17
  • f = 13.17/3
  • f = 4.39

9. The function f (x) is shown graphed below. The function g is determined by the formula g(x) = 3f (x)-2 for all values of x in
Lady_Fox [76]

Answer:

  (1)  -5

Step-by-step explanation:

Put the value where the variable is, read the graph, and do the arithmetic.

  g(2) = 3f(2) -2 = 3(-1) -2

<em>   g(2) = -5</em>

__

<em>Additional comment</em>

f(2) is the point on the graph where it is 2 units to the right of the y-axis. At that point, the graph is 1 unit below the x-axis, so f(2) = -1.

Which vertex will result in the maximum value of the function T = x – 3y?
exis [7]

Answer:

(0,-3) will give the maximum value

Step-by-step explanation:

To know the vertex, we have to substitute the coordinates in the options

we have this as follows

a) (1.5,0)

T = 1.5-3(0) = -1.5

b) (3.5,4)

T = 3.5 - 1)4)

= 3.5 - 4 = -0.5

c) (0,-3)

we have

T = 0-3(-3) = 0 + 9 = 9

d) (0,4)

we have this as:

T = 0 - 3(4) = -12
