We have the following function:
(x)  = 3x - 7
The function f translated 6 units up and 2 units rigth:
6 units up:
y  = 3x - 7 + 6
2 units rigth:
y  = 3(x-2) - 7 + 6
y  = 3x - 6 - 7 + 6
Finally:
g(x)  = 3x - 7

The function f reflected about the y-axis and translated 7 units left:
reflected about the y-axis:
y = 3(-x) - 7
y = -3x - 7
translated 7 units left:
y = -3(x+7) - 7
y = -3x - 21 - 7
y = -3x -28
Finally:
g(x) = -3x - 28

The function f stretched vertically by a factor of 2 and translated up by 5 units:
stretched vertically by a factor:
y = 6x - 14
translated up by 5 units: 
y = 6x - 14 + 5 
y = 6x - 9
Finally:
g(x) = 6x - 9

 The function f stretched vertically by a factor of 4 and translated up by 9 units:
stretched vertically by a factor of 4:
y = 12x - 28
translated up by 9 units: 
y = 12x - 28 + 9 
y = 12x - 19
Finally:
g(x) = 12x - 19

Given that our original function is:
f(x)=3x-7

To Match each verbal description to its equivalent function rule we shall proceed as follows:
The function is translated 6 units up and 2 units right. 
since f(x) cuts through point (0,-7) the translation will give us the points (2,-7) and (2,-1), since the new line is parallel to the old, the slope will be m=3, thus the equation will be:
y=3x+c
using point (2,-1)
-1=3(2)+c
-1-6=c
c=-7
thus our equation will be:
y=3x-7
thus our new equation is: g(x)=3x-7


b] The function f is reflected about the y-axis and translated 7 units left. when we reflect the function f o y -axis, the new function will be:
y=-3x-7
when we translate this 7 units to the left we shall have:
y=-3x(x+7)-7
thus the final equation is
g(x)=-3x-21-7
simplifying we obtain:
g(x)=-3x-28


c] When f is stretched vertically by a factor of 2 and translated up by 5 units we shall have the following:
when f is stretched, the new function will be:
y=2(3x-7)
y=6x-14
when the above function is translated up by 5 units we shall have:
y=6x-14+5
thus simplifying the above the function becomes
g(x)=6x-9

c] The factor f is stretched vertically by a factor of 4 and translated up by 9 units.
when f(x) is stretched by a factor of 4, the new function will be:
f(x)=4(3x-7)
f(x)=12x-28
when the function is translated up by 9 units, the new function will be:
f(x)=12x-28+9
simplifying the above we get:
g(x)=12x-19

The sum of two numbers is 19 . When the second number is subtracted from the first​ number, the difference is 17 . Find the two
zhenek [66]

Answer:

19 and 2

Step-by-step explanation:

Let x represent the first number and y represents second number

x + y = 19

x - y = 17 add two equations up

2x = 36 divide both sides by 2

x = 19 and since the difference is 17 the other number is 2

What is the real number value of m^3+ √12 m when 5m^2 = 45 ?
babymother [125]
<h3>Answer: H. 33</h3>

=============================================

Work Shown:

Solve 5m^2 = 45 for m to get

5m^2 = 45

m^2 = 45/5

m^2 = 9

m = sqrt(9)

m = 3

I'm making m to be positive so that way the expression 12m is not negative. Otherwise, sqrt(12m) would not be a real number result.

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

Plug m = 3 into the expression we want to evaluate

m^3 + sqrt(12m)

3^3 + sqrt(12*3)

27 + sqrt(36)

27 + 6

Points A, B, and C, form a triangle. The distance between point A and point B is 15 yards. The distance between point B and poin
Nana76 [90]

The total distance if Pete walks from A to B to C is 40 yards, the direct distance from A to C is more than 10 yards, and an inequality w < 30

<h3>What is inequality?</h3>

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

We have:

Points A, B, and C, form a triangle. The distance between point A and point B is 15 yards. The distance between point B and point C is 25 yards.

Total distance if Pete walks from A to B to C:

= 15 + 25 = 40 yards

As we know in the triangle the sum of the two sides is greater than the third side.

25 + 15 > AC

40 > AC

or

AC < 40

The direct distance from A to C is more than 10(25-15) yards.

The inequality w < 30 represents the distance, w, that Pete might save by taking the direct path.

Thus, the total distance if Pete walks from A to B to C is 40 yards, the direct distance from A to C is more than 10 yards, and an inequality w < 30
