The best method for solving a system of linear equations is the substitution method.

An equation is an expression that shows the relationship between two or more numbers and variables. A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be one degree.

We have been given the system of the equations as;

y = -2x + 2

y = 4x + -4

Thus, y = -2 x + 2 ........ equation number 1

y = 4 x - 4.............. equation number 2

Then substitute equation number 2 in equation number 1

4 x - 4 = -2 x + 2

4 x + 2 x = 2 +4

6 x = 6

so, x = 1

Now substitute x= 1 in equation number 2;

Therefore y =( 4 × 1) - 4

             y = 4 - 4 = 0

For x = 1 and y = 0

Hence, the best method for solving a system of linear equations is the substitution method.

Let's call the distance to the appointment 'd', and the time of the first travel (going to the appointment) 't'.

Now, we need to use the formula for the distance:

For the first part of the trip, we have the distance 'd', the average speed is 40 mph and the time is 't':

Then, for the second part of the trip (return trip), the distance is also 'd', the average speed is 30 mph, and the time is 't + 1/3', because she took 1/3 hour longer than the first trip.

So we have that:

Now, we just need to equate both 'd':

So the time 't' is 1 hour. Now we can use that to find the distance 'd':

So the distance to the appointment is 40 miles.

Mina must have planned to read 8 pages everyday.

To accomodate reading in her everyday life, without spending extra time and not disturbing other activities, Mina should read particular number of pages everyday. These pages should be enough to be completed in 7 days.

So, relating the number of pages and days -

Number of pages to be read each day = total number of pages ÷ number of days

Keep the values in relation -

Number of pages to be read each day = 56 ÷ 7

Performing division

Number of pages to be read each day = 8

Given:

a.) After 2 minutes, the tank contains 400 gallons.

b.) After 5 minutes, the tank is full.

For us to be able to determine how many gallons of water does the full tank hold, let's first determine the discharge rate of the water filling in the tank.

We get,

Since the tank is after 5 minutes of pumping water at a constant rate, we will just multiply the rate of discharge by the time it took for the tank to be full.

We get,

Therefore the volume of the tank is 1000 Gallons

Answer

The function is one-to-one.

Check Explanation.

Explanation

Like the name suggests, one-to-one functions have each input variable having exactly one unique output. That is, multiple inputs never give the same output.

Also noting that the data in the function are written as

(x, y) OR (Input, Output)

For this question, we see that all of the input variables are different and all have unique output variables.

Hence, this function is a one-to-one function.

The mass of 21,000 molecules of oxygen in scientific notation is expressed as 1.1151 x [tex]10^{-28}[/tex] grams in the proper significant digits.

The number that is provided as digits is tried and established using significant figures. A meaningful representation of numbers is carried by these digits.

The crucial or important digits that can accurately represent the exact meaning of a certain number are known as the significant figures of that number.

Frequently, significant digits are employed in place of figures. By counting out each of the values beginning with the first non-zero digit on the left, we can use it to determine the number of significant digits.

The molecular mass of Oxygen is seen as 32 grams.

So, 6.023 x [tex]10^{23}[/tex] molecules of oxygen have mass as 32 grams

So, one molecule of oxygen has mass = [tex]\frac{32}{6.023 * 10^{23}}[/tex] grams

= 5.31 x [tex]10^{-23}\\[/tex] grams

So, 21,000 molecules will have mass = 21,000 x 5.31 x [tex]10^{-23}\\[/tex] grams

= 111510 x [tex]10^{-23}\\[/tex] grams

= 1.1151 x [tex]10^{-28}[/tex] grams

Thus 21000 molecules of oxygen have a mass of 1.1151 x [tex]10^{-28}[/tex] grams.

The factor by which the current changes if the resistance increases 10% is; 90.9% reduction

Ohm's law states that the electrical current (I) flowing in a circuit is directly proportional to the voltage (V) and inversely proportional to the resistance(R). Therefore, if the voltage is increased, the current will increase provided the resistance of the circuit does not change. Thus;

I = V/R

Now, we are told that the resistance increases by 10%.

Thus, New value of resistance = 1.1R

Thus, new current/old current = 1/1.1 = 0.909 = 90.9%

Hello!

First, let's rewrite the expression here:

We will have to find the coefficients a, b and c:

• a ,= -2;

• b ,= 12;

• c ,= -15;

As we can see, coefficient a is negative. It means that the parabola will face downwards and have a maximum value.

We can obtain this point by using the two formulas below to calculate the coordinates (x, y) of this point, look:

As we know the coefficients, let's replace the values in the formulas:

Xv:

Now let's find Yv:

Doing this, we obtained the coordinate of the maximum point (x, y) = (3, 3).

As it doesn't have any restrictions, the domain will be: [-∞, +∞].

The maximum value will be when y = 3, so the range is [-∞, 3].

Look at the graph of this function below:

The ratio of surface to area to volume of the given rectangle is 5 : 4 : 8

Length of the rectangle , l = 8 cm

Breadth of the rectangle , b = 2 cm

Height of the rectangle , h = 2 cm

Perimeter of the rectangle is

            P = 2 (l +b)

               = 2(8 + 2)

               = 2 (10)

               = 20 cm

Therefore , the perimeter of the rectangle is 20 cm

Area of the rectangle is

           A = l x b

           A = 8 x 2

           A = 16 cm²

Therefore , area of the rectangle is 16 cm²

Volume of the rectangle is

         V = l x b x h

         V = 8 x 2 x 2

         V = 8 x 4

         V = 32 cm³

Therefore, volume of the rectangle is 32 cm³

Ratio of surface to area to volume = 20 : 16 : 32

Represent the proportion as a fraction

So, we have

Where p represents the proportion defined above

So, we have

E(x) = 359/449 * 39 - (1 - 359/449) * 43

Evaluate the difference
