Answer:

we conclude that an inequality 'c ≥ 5' denotes this situation.

Step-by-step explanation:

Given

  • A car dealer ship sells at least 5 minivans

When we talk about 'at least', it means we are talking about '≥' in terms of representing the 'at least' in inequality symbol.

For instance,

'm≥n' means 'm' is greater than or equal to 'n'.

It means 'm' is at least equal to 'n'.

Coming back to the question,

  • Let 'c' represent the number of minivans sold each week.

As the car dealer ship sells at least 5 minivans. so the

inequality will be: c ≥ 5

Thus, we conclude that an inequality 'c ≥ 5' denotes this situation.

Find the points of intersection of the graphs of the equations.
AURORKA [14]

Answer:

To find the point of intersection, just solve for x and y in the equations

so since x - y = -5

x = y - 5

now that we have a value of x, we will substitute x with in in the other equation

<em>5x + 3y = -9</em>

<em>5(y-5) + 3y = -9</em>

<em>5y - 25 + 3y = -9</em>

<em>8y = 16 </em>

y = 2

now use this value of y in the equation we made for x

<em>x = y - 5</em>

<em>x = 2 - 5</em>

x = -3

Hence, the point of contact is (-3 , 2)

Calculate the percentage change (increase or decease) that occurs when:
SashulF [63]

The first step is to find the CHANGE. This is done by subtracting the two values and taking the absolute value. Next step is to find the ratio of the change to the original and multiplying by 100% to make it a percentage.

So;

a)  change = Ι60 - 25Ι = 35.

     ratio of change to original = 35:25,

    multiplying by 100% will give 35/25 × 100% = 140%.

    Hence it is a 140% INCREASE.

b) change = | 30 - 66 | = 36

    the ratio is 36:66

multiplying by 100% = 36/66 × 100% = 0.545454... ×100% ≈ 54.5%

   Hence it is a 54.5% DECREASE.
