Use inverse operations to solve each equation.

1 answer:

6 0

1) -2x = 34
The inverse of multiplication is division, so divide both sides by -2.
x = -17

2) y - 3.5 = -2.1
The inverse of subtraction is addition, so add 3.5 to both sides.
y = 1.4

3) 2/3z = -6
The inverse of division is multiplication, so multiply both sides by 3z
2 = -18z
z = -1/9

60 EXTRA POINTS!!!! I need help with writing an inequality for a graph. It is below. :)

ch4aika [34]

Answer:

The answer to your question is: y ≥ - x + 6 and y ≥ x - 4

Step-by-step explanation:

Look of a pairs of points for each graph

Line 1 Line 2

A(0, 6) B (5, 1) C (7,3) D(5, 1)

m = (1- 6) / (5- 0) m = (1 - 3) / (5 - 7)

m = -5/5 = -1 m = -2 / -2 = 1

Find the line equation for each slope (y - y1) = m (x - x1)

(y - 1) = -1 (x - 5) (y - 1) = 1 (x - 5)

y - 1 = -x + 5 y -1 = x - 5

y = -x + 5 + 1 y = x - 5 + 1

y = -x + 6 y = x - 4

Inequality

y ≥ - x + 6 y ≥ x - 4

In how many ways can the letters of the word "WINNER' be arranged?

andre [41]

Because there are 6 letters in WINNER, you can use factorials to find out how many ways the letters can be arranged.

Factorials are represented with the ! symbol. Use the factorial of 6 to solve the problem:

$6! = 6 * 5 * 4 * 3 * 2 * 1 = 720$

There are 720 different ways the letters can be arranged.
