Answer:

A:2

B:-5

C:8

D:-147

Step-by-step explanation:

A: For this one, you can cancel out the negatives. Then just divide 14 by 7. Your final answer is 2. Final Answer : 2

B: This one you can forget about the negative for the first bit. Just divide 15 by 3 to get 5. Now the negative is only on one side of the equation so therefore we add the negative back into our answer. Final Answer : -5

C: Just divide 32 by 4 to get 8. No removal or substitution is needed for this one because both numbers are positive. Final Answer : 8

D: Multiply both numbers normally forgetting about the negative at first. 49 * 3 is 147. Now one of our numbers contain a negative so we plug back the negative into our answer. Final Answer : -147

Help please! - "Enter The Equation of the line in the form y= mx where m is the slope."

Dmitry [639]

Answer:

y = 1/2x

Step-by-step explanation:

Choose two points- I chose (10,5) and (0,0)

Find the slope using y2-y1/x2-x1

Use y - y1 = slope (x -x1) to get your equation

The answer should be y =1/2x

Hopefully this helps- let me know if you have any questions

Q4). Solve the equation 2x+1 = 2(1x/2 - 1) are represent the solution (s)

In-s [12.5K]

Answer:

<h3><u>Given :-</u></h3>

2X+1 = 2 [ (1X/2)-1]

Solve the equation and represent the solution on the number line and on the Cartesian plane?

<h3><u>Solution :-</u></h3>

Given equation is 2X+1 = 2 [ (1X/2)-1]

=> 2X+1 = 2[(1X-2)/2]

=> 2X+1 = 2(X-2)/2

=> 2X+1 = X-2

=> 2X-X = -2-1

=> X = -3

Therefore, X = -3

The graph is parallel to Y-axis

The coordinates are (-3,0),(-3,1),(-3,2),...

<h3><u>Scale :-</u></h3>

On X - axis 1 cm = 1 unit

On Y - axis 1 cm = 1 unit

<h3><u>Answer :-</u></h3>

The solution for the given equation is -3.
