Answer:

No solution:.

We get a no solution when the linear equality give some absurd results.

Hence, let us suppose we write the given equality as:

2x+9+3x+x=6x+10

since,

on solving this equality we get:

2x+3x+x+9=6x+10 ( on combining like terms in the left hand side of the equality)

6x+9=6x+10

6x-6x=10-9 ( on taking the variable terms to one side of the equation and constant term to other side)

0=1

which is absurd.

Hence, we get a No solution.

One solution:

one solution means that on solving the linear equality we get a unique value for our variable x and hence the solution is also called a unique solution.

We will write our equation as:

2x+9+3x+x=2x+17

on solving:

2x+3x+x+9=2x+17

6x+9=2x+17

6x-2x=17-9

4x=8

x=2.

Hence, we get a unique solution.

Infinitely many solution:

Infinite many solution means that the equation will hold true for infinitely many values of 'x' i.e we do not get a unique value.

so,

2x+9+3x+x=6x+9

2x+3x+x=6x+9

6x+9=6x+9

6x-6x=9-9

0=0

Hence, we can get infinite values or our x.

You have been hired as a marketing consultant to Johannesburg Burger Supply, Inc., and you wish to come up with a unit price for

kotegsom [21]

Answer:

q(p)= -3000p+12000

Step-by-step explanation:

For the function to be linear,

q(p)= mp + c

where

q(p): number of hamburgers sold

p: price per hamburger

m: gradient of the function

c: constant of the function

q(p)=6000 when p=2

6000=2m+c .................... equation I

0=4m+c

c=-4m........................ equation II

Substitute value of c in equation I

6000=2m-4m

m= -3000

c=12000

q(p)= -3000p+12000

Z to the power of 2 =1

stiv31 [10]

That would be written as:

$z^{2} = 1$

And the step-by-step equation would be:

$z^{2} = 1$ → we take the 2 to the right side of the equation and do the IO*

$z = \sqrt{1}$ →we solve for $\sqrt{1}$

$z = 1$ → final answer

*Ps - IO is not an existing term and stands for inverse operation. In this case, because when we take to 2 to the right side of the equation (the 2 is a power) it'll have to turn into a square root (because exponents and roots are inverse operations)

A sports club needs to raise at least $500 by selling chocolate bars for $2.50 each. Sebastian wants to know how many chocolate

mario62 [17]

Answer:

The inequality should be written as $2.50 times c is greater than or equal to c.

Step-by-step explanation:

First, identify what you know:

1) Each chocolate bar is $2.50

2) Sebastian needs to raise at least $500

So, Sebastian needs to sell at least enough chocolate bars to hit $500. The inequality cannot be written as less than or equal to, because he can't sell less than the number of chocolate bars needed to make $500.

Automatically, I can calculate the minimum number of bars he'll need to sell.

500/2.50 = 200 chocolate bars minimum

c must equal greater than or equal to $500, for Sebastian to raise enough money! So, basically Sebastian has to sell 200 bars OR more.

Hope this helps! :)
