Answers

The right answer for the question that is being asked and shown above is that: 

ON = 8x – 8
LM = 7x + 4
NM = x – 5
OL = 3y – 6

OL = NM
3y – 6 = x – 5
3y = x - 6 + 5
3y = x - 1
y = 1/3x - 1/3

ON = LM
8x – 8 = 7x + 4
x = 12
y = 1/3x - 1/3
y = 1/3(12) - 1/3
y = 4 - 1/3
y = 11/3

So the answer is
x = 12
y = 11/3

Which is one of the transformations applied to the graph of f(x) = x2 to produce the graph of p(x) = –50 + 14x – x2? A.a shift down 1 unit
B.a shift left 7 units
C.a shift right 1 unit
D.a shift up 7 units

Answers

Answer:  The correct option is (A) a shift down 1 unit.

Step-by-step explanation:   The given functions are:

f(x)=x^2,\n\np(x)=-50+14x-x^2.

we are given to select the correct option which gives one of the transformations applied to the graph of f(x) to produce the graph of g(x).

We have

p(x)=-50+14x-x^2\n\n\Rightarrow p(x)=-(x^2-14x+49)-1\n\n\Rightarrow p(x)=-(x-7)^2-1\n\n\Rightarrow p(x)+1=-(x-7)^2.

Comparing the equation of p(x) with that of f(x), we conclude that the transformations are

(i) a horizontal shift of 7 units to the right,

(ii) a vertical shift of 1 unit downwards.

So, one of the correct transformations is - a shift down by 1 unit.

The graphs of f(x) and p(x) are attached below.

Thus, (A) is the correct option.

Find the Horizontal Asymptote of the exponential function, and then identify the transformations.f(x) = -2^(2-5) + 3

Answer:jjjjjjjjjjjjjjhhhhhhheeeeeeeaaaaa

Step-by-step explanation:

Answer:

f(x)=23/8

Step-by-step explanation:

To find horizontal asymptotes: If the degree (the largest exponent) of the denominator is bigger than the degree of the numerator, the horizontal asymptote is the x-axis (y = 0). If the degree of the numerator is bigger than the denominator, there is no horizontal asymptote.

Which best describes the range of the function f(x) = 2(3)x?y > 0

y ≥ 0

y > 2

y ≥ 2

Answers

The range of the function f(x) : 2.3^(x) is y > 0.

The correct option is (A)

What is range?

The definition of range is the set of all possible values that the function will give when we give in the domain as input.

Given function is : 2.3^(x)

If we draw the graph for this, then we can see that the horizontal asymptote is 0.

So,  the range is real numbers higher than 0.

Hence, the range should be y > 0.

Multiply the decimal numbers 37.4 x 2.2 =

Answers

Basically you multiply like normal and then add in the decimal point (to figure out where it goes count how many numbers are behind the decimal (in this case 2) and then count that many places from the right into your answer and that's where it goes). So here 374 x22 =8228 but when you add in the decimal you get 82.28 :)
82.28 because once you finish multipling, you havs to movd the decimal which in this case would be two spaces to the left starting from the right
