Question

Evaluate.

(jk−1)÷j when j=−4 and k=−0.7

Enter your answer as a decimal in the box.

Answer 1

By substituting j with -4 and k with -0.7, the expression (jk-1)÷j evaluates to -0.45 when the calculations are carried out step by step.

Step-by-step explanation:

To evaluate (jk-1)÷j when j=-4 and k=-0.7, we need to plug in the values of j and k into the expression.

First, multiply j and k: (-4)(-0.7) = 2.8.

Next, subtract 1 from the product: 2.8 - 1 = 1.8.

Now, divide this result by j: 1.8 ÷ (-4) = -0.45.

Therefore, the evaluated expression as a decimal is -0.45.

Answer 2

(jk - 1) / j

jk = (-4 x -0.7) = 2.8

(2.8 - 1) / - 4

1.8 / -4 = -0.45

Answer is -0.45 when j = -4 and k = -0.7
