Answer:

n - (-6) < 9

n < 3

Step-by-step explanation:

When setting up an inequality, using the key words from the problem will help. The word 'difference' would indicate subtraction and 'less than' would be the '<' inequality sign. Since the expression is 'the difference of a number and -6', we write:

n - (-6) < 9

Whenever we subtract a negative number, we change both signs to positive:

n + 6 < 9

Using inverse operations to solve: n + 6 - 6 < 9 - 6

n < 3

How do you graph? <br> y=−4/3x+8y

trasher [3.6K]

How do we graph anything? Make a table of values for x and y and then plot each point. After plotting each point on the xy-plane, connect each point with a straight line or curve (depending on the function).

In this case, we must first isolate y.

y = (-4/3)x + 8y

y - 8y = (-4/3)x

-7y = (-4/3)x

y = (-4/3)x ÷ (-7)

y = (4/21)x

Now follow the steps above.

2<br> 3(9x - 6) = 4x + 10<br> What is the value of X In the equation

andreev551 [17]

Answer:

Step-by-step explanation:

23(9x-6) = 4x +10

207x - 138 = 4x +10

203x = 148

x = 148/203

3(9x-6) = 4x +10

27x -18 = 4x + 10

27x - 4x = 10 + 18

23x = 28

x= 28/23
