Answer:

The solution is ([4], [19]).

Step-by-step explanation:

To solve the system of equations using the substitution method, we can follow these steps:Step 1: Start with the given equations:

y = 4x + 3 (Equation 1)

y = 7 + 3x (Equation 2)Step 2: Choose one of the equations and solve for one of the variables in terms of the other variable. Let's choose Equation 1 and solve for y in terms of x:

y = 4x + 3Step 3: Substitute the expression for y from Equation 1 into Equation 2 and solve for x:

4x + 3 = 7 + 3x (Substituting y = 4x + 3 from Equation 1)

4x - 3x = 7 - 3

x = 4Step 4: Substitute the value of x found in Step 3 back into either Equation 1 or Equation 2 to solve for y. Let's use Equation 1:

y = 4(4) + 3 (Substituting x = 4)

y = 19So the solution to the system of equations is x = 4 and y = 19. Therefore, the solution is ([4], [19]).

Answer: The height would be 6 feet

Step-by-step explanation: If you want you can get the answer expert verified because I don't know how to show the work I did on a computer.

Sure! Here's an example set of data that is a function:

| x | y |

|---|---|

| 1 | 3 |

| 2 | 5 |

| 3 | 7 |

| 4 | 9 |

| 5 | 11 |

To show that this is a function, we need to check that for every value of x, there is only one corresponding value of y. We can see from the table that this is true - for example, when x=2, y=5 and there are no other values of x that give y=5.

To represent this function in the form y=m*x+b, we need to find the values of m and b. We can use the slope-intercept form of a line to do this, which is:

y = m*x + b

where m is the slope of the line and b is the y-intercept (the value of y when x=0).

To find the slope, we can use the formula:

m = (y2 - y1) / (x2 - x1)

where (x1, y1) and (x2, y2) are any two points on the line. Let's use the points (1, 3) and (2, 5):

m = (5 - 3) / (2 - 1) = 2

So the slope of the line is 2.

To find the y-intercept, we can use any point on the line and solve for b. Let's use the point (1, 3):

y = m*x + b

3 = 2*1 + b

b = 1

So the y-intercept is 1.

Now we can write the equation of the line in slope-intercept form:

y = 2*x + 1

To check that this equation matches the values in the table, we can substitute each value of x into the equation and see if we get the corresponding value of y:

When x=1: y = 2*1 + 1 = 3

When x=2: y = 2*2 + 1 = 5

When x=3: y = 2*3 + 1 = 7

When x=4: y = 2*4 + 1 = 9

When x=5: y = 2*5 + 1 = 11

These values match the values in the table, so we have shown that the set of data is a function and we have written its equation in the form y=m*x+b.

Sure, here is a set of data that is a function using at least 5 domain values and 5 range values:

```

Domain | Range

------- | --------

-2 | -4

-1 | -3

0 | -2

1 | -1

2 | 0

```

This data can be shown in a table, a graph, or a set of ordered pairs. In this case, we will show it as a table:

```

| Domain | Range |

|---|---|

| -2 | -4 |

| -1 | -3 |

| 0 | -2 |

| 1 | -1 |

| 2 | 0 |

```

We can use the equation y = m + b to find the slope (m) and y-intercept (b) of this function. The slope is calculated by finding the change in y (the range) divided by the change in x (the domain). In this case, the change in y is -4 - (-3) = -1, and the change in x is -2 - 0 = -2. Therefore, the slope is -1/-2 = 1/2. The y-intercept is calculated by finding the value of y when x is 0. In this case, the value of y is -2. Therefore, the y-intercept is -2.

The equation of this function is y = (1/2)x - 2. This function can be graphed by plotting the points in the table and connecting them with a line. The graph of this function is a straight line.

Answer:

Step-by-step explanation:

Not answer choice A because if we plug in x = -3 into -5x +2, the answer is 17. which is NOT ≤ 12

B is correct because if we plug in x = -3 into 3x-7, we get -16 which IS ≥ 16

Not answer choice C because if we plug in x = -3 into 14 +2x, we get 8, which is NOT less than 5

Not answer choice D  because if we plug in x = -3 into 1/2x + 6, we get 4.5 which is NOT greater than 11.

Answer:

-4

Step-by-step explanation:

To find the value from the given set that satisfies the inequality, we can substitute each value into the inequality and see which one makes it true.

−1/2x + 4 ≥ 6

Subtracting 4 from both sides:

−1/2x ≥ 2

Multiplying both sides by -2 (and reversing the inequality):

x ≤ -4

Now we can check each value from the set and see which one satisfies the inequality:

-6 ≤ -4 (not true)

-4 ≤ -4 (true)

-1/2 ≤ -4 (not true)

0 ≤ -4 (not true)

2 ≤ -4 (not true)

4 ≤ -4 (not true)

Therefore, the only value that satisfies the inequality is -4.

Using proportions, it is found that the expression that represents the number of reams of paper the company produced during the second year is:

⇒ 4.704 x 10¹⁰

Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.

Given that;

During the first year of operation, a company produced 8.4 x 10⁹ reams of paper.

And, During the second year, the company produced 5.6 times the number of reams of paper that it produced during the first year.

Hence, , In the first year, the company produced  reams, and in the second year, 5.6 times that, that is, we multiply the amount by 5.6, hence:

⇒ 8.4 x 10⁹ x 5.6

⇒ 4.704 x 10¹⁰

Thus, Using proportions, it is found that the expression that represents the number of reams of paper the company produced during the second year is:

⇒ 4.704 x 10¹⁰

Answer:

J = 11/4

Step-by-step explanation:

J + 17/4 = 7

7 as a fraction

7 x 4 = 28

28/4

J + 17/4 = 28/4
J + (17/4 - 17/4) = (28/4 - 17/4)

J = 11/4

Answer:

j = 11/4

Step-by-step explanation:

For quick answer just in your head multiply 4 by 7, which is 28. Then subtract 17 since that’s the given, which you will get 11. So j = 11/4. Hope this somewhat makes sense.

To solve for the value of j, we need to isolate j on one side of the equation.

First, we can simplify the left side of the equation by multiplying both sides by 4 to get rid of the fraction:

j + 17/4 = 74(j + 17/4) = 4(7)

4j + 17 = 28

Next, we can isolate j by subtracting 17 from both sides:

4j + 17 - 17 = 28 - 174

j = 11Finally, we can solve for j by dividing both sides by 4:

j = 11/4

Therefore, the value of j that satisfies the equation is j = 11/4.

we can check whether j = 11/4 is the correct solution by substituting it into the original equation and seeing if it is true.

j + 17/4 = 7

When we substitute j = 11/4, we get:

(11/4) + 17/4 = 7

Simplifying the left side of the equation, we get:

28/4 = 7

Both sides of the equation simplify to 7, which means that the solution j = 11/4 is correct.

To further verify, we can also add 11/4 and 17/4 to get:

11/4 + 17/4 = 28/4 = 7

Since we obtained the same value for both sides of the equation, we can conclude that the solution j = 11/4 is correct.

Answer:

A

Step-by-step explanation:

The formula for the perimeter of a rectangle is P = 2l + 2w, where P is the perimeter, l is the length, and w is the width.

28 = 2(5x+2) + 2x

28 = 10x + 4 + 2x

28 = 12x + 4

24 = 12x

x = 2

Therefore, the width of the rectangle is 2 cm, and the length is 5(2) + 2 = 12 cm. The correct answer is A. Width = 4 cm and Length = 10 cm.

Answer:

741a + 825b + 639c = 1375/9.

Step-by-step explanation:

To solve this problem, we need to first find the values of a, b, and c that satisfy the given system of equations. We can use any method of solving systems of linear equations, such as substitution or elimination. Here, we will use the elimination method:

Multiplying the first equation by -4 and adding it to the second equation, we get:

-20b - 36c = -2

Multiplying the first equation by -7 and adding it to the third equation, we get:

29b + 45c = 8

Multiplying the second equation by -29/20 and adding it to the third equation, we get:

-21b - 39c = 67/10

Now we have three equations in two variables. We can solve for b and c using any method, such as elimination or substitution. Here, we will use substitution:

From the second equation, we can solve for a in terms of b and c:

a = (2 - 2b - 3c)/4

Substituting this expression for a into the third equation, we get:

741/4 - 825/2 b + 639/6 c = 9

Simplifying and solving for b, we get:

b = (3/5) - (3/5) c

If this helps, please mark my answer as brainliest

Substituting this expression for b into the second equation, we get:

(27/5) c = (2/5)

Solving for c, we get:

c = -(2/27)

Substituting this value of c into the expression for b, we get:

b = (3/5) - (3/5) (-2/27) = (11/27)

Substituting the values of a, b, and c into the expression 741a + 825b + 639c, we get:

741a + 825b + 639c = 741[(2 - 2b - 3c)/4] + 825b + 639c

= 741[(2 - 2(11/27) - 3(-2/27))/4] + 825(11/27) + 639(-2/27)

= 741(5/27) + 275/3 - 426/9

= 1375/9

Therefore, 741a + 825b + 639c = 1375/9.
