Multiply all terms by x and cancel:

−7 /2

(Works in original equation)

Answer: -7/2

Using multiplication, the equation has the solution is -7/2.

The multiplication is "the process of multiplying one number is to multiply to its certain number of times".

According to the question,

[tex]\frac{8}{x} + 3 = \frac{1}{x} +1[/tex]

[tex]\frac{(8+3x)}{x} = \frac{1+x}{x}[/tex]

8 + 3x = 1 + x        [By cancel 'x' on both denominator]

 8 - 1 = x - 3x    

   7    = -2x

   x   = - [tex]\frac{7}{2}[/tex]      

Hence, using multiplication the equation has the solution is -7/2.

Answer:

The solutions are (0, 4) and (-3, -5).

Step-by-step explanation:

Yes, first substitute y = 3x + 4 in the first equation:

3x + 4 = -x^2 + 4

x^2 + 3x = 0

x(x + 3) = 0

x = 0, -3

When x = 0 , y = -(0)^2 + 4 = 4 and

when x = -3 , y = -(-3)^2  + 4 = -9 + 4 = -5.

Step-by-step explanation:

if im wrong sorry

The requried scientist should use 80 ounces of Solution A (35% salt) and 10 ounces of Solution B (80% salt) to obtain a 90-ounce mixture that is 40% salt.

Let's assume the scientist uses x ounces of Solution A and y ounces of Solution B to obtain the desired mixture.

From the information given, we can set up the following equations:

Equation 1: The total amount of solution is 90 ounces, x + y = 90

Equation 2: The amount of salt in the mixture can be expressed as, 0.35x + 0.80y = 0.40 * 90

Simplifying Equation 2:
0.35x + 0.80y = 36

To solve these equations, we can use substitution or elimination. Let's use the substitution method.

From Equation 1, we can express x = 90 - y and substitute it into Equation 2:

0.35(90 - y) + 0.80y = 36

31.5 - 0.35y + 0.80y = 360

45y = 4.5y = 10

Substituting y = 10 back into Equation 1:

x + 10 = 90

x = 80

Therefore, the scientist should use 80 ounces of Solution A (35% salt) and 10 ounces of Solution B (80% salt) to obtain a 90-ounce mixture that is 40% salt.

Answer:

1.a 519.615

1.b 173.21

2. It would take approximately 2.1 minutes

Step-by-step explanation:

If the population triples every hour then after one hour the population must be:

population(0) = 100

population(1) = 100*3 = population(0)*3

After two hours:

population(2) = population(1)*3 = population(0)*3*3 = population(0)*3²

After three hours:

population(3) = population(2)*3 = population(0)*3²*3 = population(0)*3³

Therefore the equation that will model the growth of the population is:

population(n) = 100*3^n

1. a.

We first need to convert the time from minutes to hours, to do that we must divide by 60. We have:

time = 90/60 = 1.5

We then apply this value in the "n" from the equation above:

population(1.5) = 100*3^(1.5) = 519.615

1.b.

We have to follow the same steps as before:

time = 30/60 = 0.5

population(0.5) = 100*3^(0.5) = 173.21

2.

We now use the same equation as before, but we want to solve for n isntead of "population". We have:

1000 = 100*(3^n)

100*(3^n) = 1000

3^n = 1000/100

3^n = 10

ln(3^n) = ln(10)

n*ln(3) = ln(10)

n = ln(10)/ln(3) = 2.095

It would take approximately 2.1 minutes

To find the total area of the octagon, we need to find the area of the rectangle and subtract the areas of the four congruent right triangles that were removed.

Let's assume the length of the rectangle is L and the width is W.

The area of the rectangle is L * W.

The two smaller sides of the right triangle are congruent to the width of the rectangle, which is W. The hypotenuse of each right triangle is congruent to the length of the rectangle, which is L.

The area of a right triangle is (base * height) / 2. In this case, the base is W and the height is L.

So, the area of one right triangle is (W * L) / 2.

Since there are four congruent right triangles, the total area of the right triangles is 4 * (W * L) / 2 = 2 * (W * L).

Therefore, the total area of the octagon is (L * W) - 2 * (W * L).

The total area of the octagon = L * W - 2 * W * L.

We don't know the actual values of L and W, so we cannot calculate the exact area. However, we can simplify the expression.

The total area of the octagon = L * W - 2 * W * L = LW - 2WL = LW - 2WL = LW - 2WL = LW.

Therefore, the total area of the octagon is equal to the area of the rectangle.
