Answer:

x = 4

Step-by-step explanation:

Step 1: Write equation

-2x + 1 = -4x + 9

Step 2: Solve for <em>x</em>

  1. Add 4x to both sides: 2x + 1 = 9
  2. Subtract 1 on both sides: 2x = 8
  3. Divide both sides by 2: x = 4

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

-2(4) + 1 = -4(4) + 9

-8 + 1 = -16 + 9

Two numbers multiply to be -7 and add to be -6. What are the numbers?<br><br> Example; 2,3
rewona [7]

<u>Given</u>:

Let the two numbers be x and y.

Two numbers multiply to be -7 and add to be -6.

This can be written in equation as,

xy=-7 and

x+y=-6

<u>Value of the two numbers:</u>

Let us determine the value of the two numbers using substitution method.

Substituting y=-6-x in the equation xy=-7, we get;

x(-6-x)=-7

Simplifying, we get;

       -6x-x^2=-7

   x^2+6x-7=0

(x+7)(x-1)=0

x=-7, 1

Thus, the values of x are x = 1,-7

When x = 1 , the equation x+y=-6 becomes y=-7

When x = -7, the equation x+y=-6 becomes y=1

Therefore, the two numbers are 1 and -7

In 1979, zoologists estimated the number of fish in a local pond to be about
rewona [7]

Answer:

693 fish

Step-by-step explanation:

In 10 years, we can tell that the amount of fish increased by 1.833...(990 divided by 540) times. If we divide 1.833... by 10, we can find how much the pond increases by yearly. we get 0.1833... If we multiply that by 7 (because the gap between 1986 and 1979 is 7 years), we get 1.2833... So, if we multiply 540 by 1.28333..., we get 693 fish.

?simplified the expression
larisa [96]
The first two negatives cancel out and you're left with positive 4. Now go inside the square root and do the exponent. -4*-4 = 16. Then do the -4*3*1 = -12. Do 16-12 = 4. now the square root of 4 = 2. at the dominator is 2*3 = 6. right now they problem should look like 4+- 2/ 6. from there you split the problem in two. so you have 4+2/6   &     4-2/6     then you solve both problems.
           6/6               2/6
             1                  1/3
1 & 1/3 are your answers. I hope this helped!
