Answer: x= 3/2 and y= 1/2

Step-by-step explanation:

Since both equations are equated to y, you just need to use substitution to create the equation below:

-x+2 = 3x-4

Solve the equation for x:

4x=6

x=6/4=3/2

Plug in x into any one of the given equations to find the value of y:

y=-x+2

y= - (3/2)+2

y= - (3/2)+4/2

y= 1/2

Hope this helps!

The solution to the system of equations will be x= 3/2 and y= 1/2.

A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, often known as a system of equations or an equation system.

An equation is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

The given equations are y=−x+2 and y=3x−4 ​to calculate the values of x and y using the substitution method.

Since both equations are equated to y, you just need to use substitution to create the equation below:

-x+2 = 3x-4

Solve the equation for x:

4x =6

x =6/4=3/2

Plug x into any one of the given equations to find the value of y:

y =-x+2

Solve for the value of y.

y = - (3/2)+2

y = - (3/2)+4/2

y = 1/2

Hence, the solution for the equation will be x= 3/2 and y= 1/2.

Answer:

[tex]\large\boxed{\sf n^{th} \ term =3n}}[/tex]

Step-by-step explanation:

Find common difference from subtracting any term in the sequence with the previous term.

[tex]\large{\sf 6-3}=3[/tex]

Apply nth term formula.

[tex]\large{\sf a_n=a_1+(n-1)d[/tex]

[tex]\large{\sf d=3 \ \ a_1=3}[/tex]

[tex]\large{\sf a_n=3+(n-1)3[/tex]

[tex]\large{\sf a_n=3+3n-3[/tex]

[tex]\large{\sf a_n=3n}[/tex]

Answer:

a(n) = 3 + 3(n -1)

Step-by-step explanation:

Note that each new term is found by adding 3 to the previous term.  The first term is 3 and the common difference is 3.  Thus, the formula for the nth term is

a(n) = a(1)+d^(n - 1)

or, in this case,

a(n) = 3 + 3(n -1)

Answer:

Step-by-step explanation:

expression for surface area = a² + a √(a²/4+h²)

=4² + 2(4) √(4²/4+5²)

=16 + 8  √(16/29)

= 24 √0.55

= 20.65

The correct answer is the last one, 7.5 x 104. (the sum is 772.5)

if you multiply it the sum is 772.5, and all the other ones sum is less than 772.5

Answer:

80 people are required to run 35 machines

Step-by-step explanation:

Write and solve an equation of ratios:

  p       35

------- = -----

 16         7

where p is the number of people needed to run 35 machines.

Cross-multiplying yields 7p = 16(35), or p = 16(5), or p = 80

80 people are required to run 35 machines.

Answer:

96 minutes in the whole game or 1 hour and 36 minutes and 1/8 of the game is left.

Step-by-step explanation:

So we know that there are 4 quarters in a game. So if they're halfway through the 3rd quarter with 12 minutes left in the game, that means half a quarter equals 12 minutes. That means a full quarter equals 24 minutes. Then we do 24 *4 which is 96. So there are 96 minutes in the whole game and there 1/8 of the game left since 96/8=12.

Answer:

a) 6x²/2x³-4

b)  [tex]2ln (2x^3-4)+ C[/tex]

Step-by-step explanation:

a) Given the ln(2x³-4). We will use the chain rule in differentiating the function

If y = ln(2x³-4);

u = 2x³-4; du/dx = 3(2)x³⁻¹

du/dx = 6x²

y = ln u; dy/du = 1/u

According to chain rule, dy/dx = dy/dy*du/dx

dy/dx = 1/u * 6x²

dy/dx = 1/2x³-4 * 6x²

dy/dx = 6x²/2x³-4

Hence, the derivative of the given function is 6x²/2x³-4

b) Given an integral function [tex]\int\limits {\frac{12x^2}{2x^3-4} } \, dx[/tex], the integral problem can be solved using integration by substitution method as shown below;

From the question, let y = 2x³-4... 1, dy/dx = 6x²

dx = dy/6x² ... 2

Substituting equation 1 and 2 into the question given;

[tex]\int\limits {\frac{12x^2}{y} } \,\frac{dy}{6x^2} \\\\= \int\limits {\frac{2dy}{y} } \\\\= 2 \int\limits {\frac{dy}{y} }\\\\= 2lny + C\\substituting\ y = 2x^3-4\ into\ the \ resulting\ function\\\\= 2ln (2x^3-4)+ C[/tex]

==================================================

Explanation:

Ignore the values 3000 and 1000 as they are simply labels for the printer names (or brand models). I'll call the two printers A and B for simplicity.

Printer A can produce a large document in 1/4th the time printer B can do the same job. So we can say x = (1/4)y where x and y are the times it takes for both printers to do the job if they work alone. Solving for y gets us y = 4x.

Printer A can do the full job, on its own, taking x hours. It's rate is 1/x jobs per hour. Printer B's rate is 1/y = 1/(4x) jobs per hour for similar reasons.

Their combined rate is

1/x + 1/(4x) = 4/(4x) + 1/(4x) = 5/(4x)

Set this equal to 1/6 and solve for x. The 1/6 represents the combined rate based on how they can work together to get the job done in 6 hours.

-----------

5/(4x) = 1/6

5*6 = 4x*1 .... cross multiply

30 = 4x

4x = 30

x = 30/4 ... divide both sides by 4

x = 7.5

Printer A takes 7.5 hours to do the job alone

y = 4x

y = 4*7.5

y = 30

Printer B takes 30 hours to get the job done if it worked alone

-----------

Note how

1/x + 1/y = 1/7.5 + 1/30 = 4/30 + 1/30 = 5/30 = 1/6

so this confirms we have the right answer.

Answer:

18.9 ft²

Step-by-step explanation:

Surface area of this cylinder = area of the bottom and top circles + area of the curved surface.

Area of the two circles = 2πr² , where r is the radius.

Area of the curved surface = 2πrh , where r is the radius and h is the height.

Radius = [tex]\frac{1}{2}[/tex] × diameter

Area of the two circles = 2 × π × ([tex]\frac{2}{2}[/tex])² = 6.3 ft² (answer rounded up to nearest tenth)

Area of the curved surface = π × diameter × h = π × 2ft × 2ft = 12.6 ft² (answer rounded up to nearest tenth)

The surface area of the cylinder = 6.3 ft² + 12.6 ft² = 18.9 ft²

Answer:

20 or 55

Step-by-step explanation:

It depends because i am not sure what f(x) is.

Case 1: f(x)=x^2

We know h(x)=7 hence f(h(x))=7^2=49 hence g(f(h(x)))=49+6=55

Case 2: f(x)=x*2

We know h(x)=7 hence f(h(x))=2*7=14 hence g(f(h(x)))=14+6=20

Note: x^2 is x to the power of 2 while x*2 is x times 2.

Answer:

the answer is 3

Step-by-step explanation:

if on the x-axis is -1 go over to -1 on the x- axis and then go up to the peak of the line and on the y- axis it would be 3

y=3

The value of output will be 3.

A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.

Given that;

The value of input (x) = - 1

Now,

Since, The value of input (x) = - 1

By graph it is clear that;

At value x = - 1, we get;

The value of output (y) = 3

Thus, The value of output (y) = 3

Answer:

Purchasing the bag of 6 lemons is the better buy.

Step-by-step explanation:

There are two ways that we can do this: find the unit rate or find how the LCM.

---

The first way is more orthodox, and you should definitely use it in harder problems. We can set up two ratios like so.

2 : 0.99

6 : 2.5

Let's simplify the ratios so the left side is one.

2 : 0.99 = 1 : 0.495 by dividing both sides by 2.

6 : 2.5 = 1 : 0.41666... by dividing both sides by 6.

Comparing the two ratios, we can conclude that the second one is smaller, therefore the bag of 6 lemons costs less.

---

The second way, although not very efficient with big numbers, works well with small numbers like these.

First, we need to find the LCM, or the least common multiple. The LCM of 2 and 6 is 6, as 6 is a multiple of both 2 and itself.

Now we must make the amount of lemons match each other so we can compare the price.

2 : 0.99 = 6 : 2.97 by multiplying by 3.

The second ratio stays the same.

2.50 is smaller than 2.97, so the second ratio is smaller than the first, reaching our previous conclusion.
