Answer: B) False

Detailed Explanation:

We need to find the variables having equal coefficients or make the coefficients of some variable equal because we will be able to eliminate a variable. For eg. take the following pair of linear equations.

=> x + y = 14 (Eq. 1)
=> x - y = 4 (Eq. 2)

As we see, the coefficients of x and y are same but in y, the coefficients are +1 and -1 which can be easily cancelled while adding the equations. This will eliminate the variable y. So, we can find the value of x and then substitute it in any equation to find the value of y.

Two points located on jk are j (-1,-9) and k (5,3). What is the slope of jk?
Ivenika [448]

Answer:

2

Step-by-step explanation:

slope of line= \frac{y1 - y2}{x1 - x2}

slope of JK

=  \frac{3 - ( - 9)}{5 - ( - 1)}  \\  =  \frac{3 + 9}{5 + 1}  \\  =  \frac{12}{6}  \\  = 2

Pls I need help with his math problem
Leno4ka [110]

Answer:

  a) P = 0.08s +200

  b) $488

  c) $6250

Step-by-step explanation:

<h3>a)</h3>

Your answer is correct. The commission rate is multiplied by the sales amount, and that product is added to the guaranteed pay to get the paycheck amount:

  P = 0.08s +200

__

<h3>b)</h3>

Fill in 3600 for s and do the arithmetic.

  P = 0.08×3600 +200 = 288 +200 = 488

The paycheck amount will be $488.

__

<h3>c)</h3>

Use the equation for part (a) and solve for P = 700.

  700 = 0.08s +200

  500 = 0.08s . . . . . . subtract 200

  500/0.08 = s = 6250 . . . dollars; divide by the coefficient of s to get this

Sales would have to be $6250.
