Answer:

The perimeter of ABC is 36 feet

Step-by-step explanation:

ABC is Similar/in ratio to DEF.

Using the side BC, we can tell that it is corresponding to side EF.

This makes the ratio between the two sides 15:5 or, 3:1

This means that the ratio of ABC and DEF's perimeters is 3:1 feet

Because we know the perimeter of DEF-12 ft- We can substitute this number in the ratio which means that 3(12):12 is the ratio of the perimeters

This means that the perimeter of ABC is 3*12, or 36 feet

PLS HELP Given the following table with selected values of the linear functions g(x) and h(x), determine the x-intercept of g(h(
kiruha [24]

Using linear and composite functions, it is found that the x-intercept of g(h(x)) is x = -\frac{5}{6}, given by option B.

-------------------------------

The equation of a line is:

y = mx + b

In which:

  • m is the slope.
  • b is the y-intercept.

Function g:

  • Two of the points are (-6,16) and (-4,10).
  • The slope is given by <u>change in y divided by change in x</u>, thus:

m = \frac{10 - 16}{-4 - (-6)} = -3

Thus:

g(x) = -3x + b

Point (-4,10) means that when x = -4, g(x) = 10, and we use this to find b, so:

10 = -3(-4) + b

12 + b = 10

b = -2

Then

g(x) = -3x - 2

Function h:

  • Two of the points are (-6,-11) and (-4,-7).
  • The slope is:

m = \frac{-7 - (-11)}{-4 - (-6)} = \frac{4}{2} = 2

Thus:

h(x) = 2x + b

Point (-4,-7) means that when x = -4, h(x) = -7, and we use this to find b, so:

-7 = 2(-4) + b

-8 + b = -7

b = 1

Then

h(x) = 2x + 1

The composite function is:

g(h(x)) = g(2x + 1) = -3(2x + 1) - 2 = -6x - 3 - 2 = -6x - 5

The x-intercept it the zero of the function, thus:

-6x - 5 = 0

6x = -5

x = -\frac{5}{6}

Which is option B.
