Answer:

The linear equation which models this situation is given by:

y = 60x + 25

Step-by-step explanation:

It is given that:

A plumber charges a consultation fee of $25 then charges $60 an hour.

Let x represents the number of hours.

and y represents the total fee for x hours.

This means that x is an independent variable since the value of such a variable is to be assigned and y is the dependent variable since the value of y is obtained corresponding to different values of x.

Hence, we have:

The total cost will be:

y= 60x+25

The linear equation is:

$25 consultation fee: b
$60 an hour to repair: mx

y = $60x + $25
the answer is a

Answer:

m∠RPQ = 8°

Step-by-step explanation:

m∠QRS = 4x - 15

m∠RPQ = x + 1

m∠PQR = x - 2

m∠QRS is exterior angle and m∠RPQ and m∠PQr are opposite interior angles to m∠QRS

m∠QRS = m∠RPQ + m∠PQR {Exterior angle property of triangle}

4x - 15 = x +1 + x - 2

4x - 15 = x + x + 1-2 {Combine like terms}

4x - 15 = 2x - 1 {Subtract 2x from both sides}

4x - 2x - 15 = - 1

2x - 15 = - 1 {Add 15 to both sides}

2x = -1 + 15

2x = 14 {Divide both sides by 2}

x = 14/2

x = 7

m∠RPQ = x + 1 = 7 + 1 = 8°

If ab = c - d, which of the following is an expression for d in terms of a, b, and c?

horsena [70]

ANSWER

$d = - ab + c$

EXPLANATION

The given expression is

$ab = c - d$

To find an expression for d in terms of a, b, and c, means we want to make d the subject of the relation.

This means that, we need to isolate d on one side of the equation while all other terms are on the other side.

We subtract from both sides of the equation to obtain,

$ab - c = - d$

We now divide through by -1, to get,

$- ab + c = d$

Or

$d = - ab + c$
