If axb=0, then a=0 or b=0 3x=0

Mathematics
1 answer:
stepladder [879]4 years ago
4 0

Answer:

The given equation is

ax b= 0,

As we see that, it is a linear equation in one variable containing two constant.

So , a≠ 0 [then equation has no meaning.If a=0 , then 0 \times x=0, which is meaningless]. ∴ a=0 is incorrect.

Similarly , b≠ 0 [ Reason same as above]. ∴b=0 is incorrect.

⇒3 x=0

⇒x=0 is the correct response.

Let me explain by this giving an example

⇒5 x=0

⇒ x=0 but 5≠0

So, x=0 or 3 x=0 is correct response.

Which figure represents the image of parallelogram LMNP after a reflection across the line y = x? (see image)
loris [4]

When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. This gives you such reflection rule:

(x,y)\rightarrow (y,x).

From the diagram:

L(3,1), M(4,3), N(5,3) and P(4,1).

Using the reflection rule, you can find coordinates of image points:

L'(1,3), M'(3,4), N'(3,5) and P'(1,4).

As you can see, these are coordinates of vertices of the figure C.

Answer: correct choice is option 3 - figure C.

A sandwich shop charges $3.75 for a sandwich with meat and cheese and $0.15 for each additional topping. You can spend at most $
zimovet [89]

Answer:

3.75 + 0.15n ≤ 5.25

Step-by-step explanation:

You can not spend more than $5.25 so the inequality sign must be less than or equal to

If you know the shop charges a minimum of $3.75 for a sandwich, you need to include that in your equation

The $0.15 for additional toppings is included as $0.15 multiplied by n (0.15n)

n can be from 0-10, as 10 is the most toppings you can get before you go over your spending limit and you don't have to pay for additional toppings if you don't want to.

What is the inverse of f(x)=(-2x+2)/(x+7)?
Nana76 [90]

By applying the concept of the inverse of a function and <em>algebraic</em> handling, we conclude that the inverse of f(x) = (- 2 · x + 2)/(x + 7) is g(x) = (- 7 · x + 2)/(x + 2).

<h3>How to find the inverse of a function</h3>

In this question we have a <em>rational</em> function f(x) and finding its inverse consists in clearing x in terms of f(x). Prior any algebraic handling, we need to apply the following substitutions:

x \to y

f(x) \to x

x = \frac{-2\cdot y + 2}{y+7}

x · (y + 7) = - 2 · y + 2

x · y + 7 · x = - 2 · y + 2

2 · y + x · y = - 7 · x + 2

y · (2 + x) = - 7 · x + 2

g(x) = \frac{- 7\cdot x + 2}{x + 2}

By applying the concept of the inverse of a function and <em>algebraic</em> handling, we conclude that the inverse of f(x) = (- 2 · x + 2)/(x + 7) is g(x) = (- 7 · x + 2)/(x + 2).
