Answer:

It is necessary four parameters.

Step-by-step explanation:

Since the augmented matrix of the consistent system has rank equal to three then the number of free variables is (number of unknows)-rank then there are 7-3=4 free variables. This means that are necessary four parameter to specify all solutions.

A chair rental company charges $100 for delivery plus $3 per chair.
sergey [27]

Answer:

103 chairs

Step-by-step explanation:

cost = fee + cost per chair * number of chairs

410 = 100 + 3*c

Subtract 100 from each side

410-100 = 100+3c-100

310 = 3c

Divide by 3

310/3 = 3c/3

103.3=c

We cannot rent part of a chair so we round down

103 chairs

Which function could represent the value of a rare coin that increases over time? y=−32x+1y is equal to negative 3 halves x plus
KATRIN_1 [288]

The function that could represent the value of a rare coin that increases over time is; y = ²/₃x + 2

<h3>How to create linear equations?</h3>

We want to find which of the equations below could represent the value of a rare coin that increases over time

y = -³/₂x + 1

y = -²/₃x - 7y

y = ²/₃x + 2

y = ³/₂x - 6

Now, the general form of a linear equation in slope intercept form is;

y = mx + c

where;

m is slope

c is y-intercept

Now, for the equation to be increasing over time, it means the slope must be positive and the y-intercept must also be positive.

Looking at the given options, the only one where slope and y-intercept is positive is y = ²/₃x + 2

Half a number plus 5 is 11.What is the number?​
SOVA2 [1]
<h3>Solution :</h3>

<u>Let x be the number</u>

\small\bold\red{→}\small\bold{(\frac{1}{2} )x + 5 = 11}

\small\bold\red{→}\small\bold{(\frac{1}{2})x + 5 - 5 = 11 - 5}

\small\bold\red{→}\small\bold{(\frac{1}{2})x = 6}

\small\bold\red{→}\small\bold{2 × (\frac{1}{2})x = 6 × 2 }

\small\bold\red{→}\small\bold{x = 12}
