Answer:

Kindly check explanation

Step-by-step explanation:

Given the equation :

4x / 7 - 6 = - 20

4x / 7 = - 20 + 6 (move - 6 to the right hand side, the - sign attached to 6 changes to positive)

4x / 7 = - 14 ( - 20 + 6 = - 14)

4x = - 98 ( multiply both sides by 7 in other to isolate 4x)

x = - 24.5 (Divide both sides by 4, in other to isolate x and obtain it's value).

Which transformation from the graph of a function f(x) describes the graph of 5f(x)
sattari [20]

Answer:

Dilation

Step-by-step explanation:

Given

Main function: f(x)

Resulting function: 5f(x)

Required

Which transformation exists between both functions

The general explanation is that:

When a function f(x) is multiplied by a constant k, the resulting function g(x) is a dilation of f(x).

Mathematically, if the following relationship exists between f(x) and g(x)

g(x) = k.f(x)

Then g(x) is a dilation of f(x) and k is the constant of proportionality or dilation ratio

In this case:

g(x) = 5f(x)

So, the transformation that answers the question is dilation.

Delia relative long jump length was recorded as 0. What does this mean
Deffense [45]

<span>When we say about an object relative to something, this only means that we are comparing an object’s characteristic to that of our reference. So in this case, I think we are referencing Delia’s jump to someone else. Say our reference has a long jump length of 5 meters, since Delia’s relative long jump length is 0, this means that relative to the reference there is no difference. Therefore, Delia’s jump length is also 5 meters.</span>

10. The perimeter of the table shown is 16 feet. Write an equation in
Aliun [14]

Answer:

p = 2

q = 6

r = 16

x = 5 feet

Step-by-step explanation:

The perimeter of the rectangle is

P=2(\text{Width}+\text{Length})

In your case,

Width = 3 feet

Length = x feet

So, the perimeter is

P=2(3+x)\\ \\P=6+2x

Since the perimeter is 16 feet, we have

2x+6=16

Hence,

p = 2

q = 6

r = 16

Solve this equation for x:

2x+6-6=16-6\\ \\2x=10\\ \\x=\dfrac{10}{2}=5\ feet
