Evaluate the following expression 2x - |4 - 7x| when x = -3

Mathematics
1 answer:
HACTEHA [7]3 years ago
4 0

Answer:

-31  

Step-by-step explanation:

2x - abs(4 - 7x)

2x = 2 * - 3 = - 6

4 - 7x = 4 - 7*-3 = 4 + 21 = 25

-6 - abs(25)

-6 - 25 = -31

You should note three things.

1. the absolute value of 25 is 25

2. There is a - sign outside the influence of the 25 so 25 becomes - 25

3. - 6 - 25 = - 31

Answer:

6 inches by 10 1/2 inches by 30 inches

Step-by-step explanation: To find this answer you have to multiply the old dimensions by the scale factor which is 3/4. You would do 8 times 3/4 which is 6 inches. Then 14 inches times 3/4 which is 10 1/2. And then 40 inches times 3/4 and that answer is 30 inches. Those are the new dimensions for the cabinet.

Four is no less than the quotient of a number x and 2.1
shusha [124]
<span>The inequality is 4 ≥ x/2.1, and the answer is 8.4 ≥ x (or x ≤ 8.4).

Explanation:
"No less than" means it can be more than this or equal to, so we use 4 greater than or equal to.
Quotient means division, so we write x/2.1.

To solve this, we multiply both sides by 2.1:
4*2.1 ≥ x
8.4 ≥ x.</span>
