Answer:

The slope is 3/2

Step-by-step explanation:

The slope is a in the equation y= ax +b

The equation is -8y = -12x +9 -7 → -8y = -12x +2

When we make this possitive by multiplying by -1 the equation will be

8y= 12x -2

To get Y we have to divide by 8

y= 12/8 x - 2/8

The slope is 12/8 or if we simplify it 3/2

Answer:

$X\geq$ -5

Step-by-step explanation:

$4x+6\geq 6x+10\\-6x -6x\\4-6=-2\\-2x+6\geq 10\\ -6 -6\\\frac{-2x}{-2} \geq \frac{10}{-2} \\x\geq -5$

Hope this helps

Solve (2x-1/4)+(x/3)=2 Please provide a step by step with explanation

Answer:

x = 27/10 or x = 2.7

Step-by-step explanation:

Step 1: Get rid of the denominator.

LCD of 4 & 3: 12

Multiply both sides by 12.

12 ( 2x - 1 / 4 ) + 12 ( x / 3 ) = 12 (2)

Reduce the numbers.

3 ( 2x - 1) + 4x = 24

Step 2: Distribute.

6x - 3 + 4x = 24

Step 3: Collect like terms.

6x + 4x = 24 + 3 ( - 3, the sign change when moved to the other side)

10x = 27

Step 4: Solve for x.

Multiply both sides by 10.

10x / 10 = 27 / 10 (the 10 cancels out)

x = 27 / 10 or x = 2.7

Answer: x = 27 / 10 or x = 2.7
