Answer:

The solution of the equation graphically are (-3,0) and (4,-7).                        

Step-by-step explanation:

Given : Equation -x-3 = x^2 -2x- 15

To find : Solve the equation using graph?

Solution :

Let y=-x-3 be the equation (1)

y= x^2 -2x- 15 be the equation (2)

If we plot the equation (1) and (2) in the graph then the intersection point gives you the solution of the equation.

Equation (1) y=-x-3 is shown in blue line.

Equation (2) y=-x-3 is shown in red line.

The intersection points of both the equation are (-3,0) and (4,-7).

Therefore, The solution of the equation graphically are (-3,0) and (4,-7).

Refer the attached figure below.

How can you use the multiplication property of equality to rewrite the equation 0.6x+4.8=7.2 so that the numbers in the problem
Mars2501 [29]

We are given the equation:

0.6 x + 4.8 = 7.2

 

In this case, the multiplication property of equality states that whatever is multiplied on one side should also be multiplied on the other side. Now we need to find the number that will make everything a whole number, in this case 5. Multiply everything by 5:

5 * (0.6 x + 4.8 = 7.2)

3 x + 24 = 36

However we can see that we can still further simplify the equation by multiplying everything by 1/3:

(1/3) * (3 x + 24 = 36)

x + 8 = 12

or

x = 4

Find x if a] 5^x=625 root 5 b] 3^2x-1 = 243
katen-ka-za [31]

x=3, you can find this by using finding common bases for equation b because 243=3^5. Because of that you can get rid of three on both sides to get the equation 2x-1=5 and then just solve for x to get x=3. For the first equation 5^3=625 so that also proves x=3.

Sorry if my explanation is a little disorganized if you need more help feel free to ask
