Six times a number decreased by ten is eight. Find the number.
A) 2
B) 3
C) 4
D) 5

The interval notation is:

0 < x ≤ 30; 15 < x < 40; 30 ≤ x ≤ 85;

The  second and third car seats are suitable.

The number lines shows the weights of the car seats which is designed for in comparison the weight of the 32lb child.

Three car seats are designed as follows:

As the seat designed for a child upto and including 30 lb would not be suitable for 32 lb child. Because 32lb is more than the 30 lb.

Now, the seat designed for a child between 30 lb and 85 lb, 30lbs and 85lbs would be suitable as the child is within these weight ranges that is 32lb.

The interval notation is:

0 < x ≤ 30; 15 < x < 40; 30 ≤ x ≤ 85;

The  second and third car seats are suitable.

Answer:

(−6, 0) , (−1, −2)  and (−5, −1)

Step-by-step explanation:

The given inequality is  x+3y ≥ −8

Substitute all the given points in this inequality and check which points satisfy.

For (−6, 0)

-6+3(0) ≥ −8

- 6 + 0  ≥ −8

- 6 ≥ −8   => True.

Hence, (−6, 0) is a solution.

For (−1, −2)

-1 + 3(-2) ≥ −8

-1 - 6 ≥ −8

- 7 ≥ −8 => True.

Hence, (−1, −2) is a solution.

For (−5, −1)

-5 + 3 (-1) ≥ −8

- 5 -3  ≥ −8

-8 ≥ −8=> True.

Hence, (−5, −1) is a solution.

For (−16, 2)

-16 +3 (2) ≥ −8

-16 + 6 ≥ −8

-10≥ −8 => False.

Hence,(−16, 2) is not a solution.

For (0, -3)

0 + 3(-3) ≥ −8

-9  ≥ −8=> False.

Hence, (0, -3) is not a solution.

Therefore, below ordered pairs are solutions of the given inequality

(−6, 0) , (−1, −2)  and (−5, −1)

Final answer:

The slope-intercept equation of the line that passes through (1, 2) and (3, 4) is y = x + 1, with a slope of 1 and a y-intercept of 1.

Explanation:

To find the slope-intercept equation of a line that passes through the points (1, 2) and (3, 4), we first need to determine the slope of the line. We use the formula for the slope (m) given by the change in y over the change in x, or Δy/Δx. Calculating the slope, we get:

m = (4 - 2) / (3 - 1) = 2 / 2 = 1.

Now we have the slope, we can use the slope-intercept form of the line, which is y = mx + b, where m is the slope and b is the y-intercept. Plugging in one of the points, say (1, 2), into this equation gives us:

2 = (1)(1) + b

Which simplifies to:

b = 2 - 1 = 1

So the y-intercept (b) is 1. Therefore, the slope-intercept equation of the line is:

y = x + 1

Answer:

Your answer would be D.

Step-by-step explanation:

Answer:

The given equation of the curve is

 y= x² - 36

To find it's inverse we have to convert y in terms of x.

So, adding 36 to both sides of equation

→ y + 36=x² -36 + 36

→ y + 36 = x²

→ x² = y+ 36

→ x =[tex]\pm[/tex][tex]\sqrt{y+36}[/tex]

Now, to find inverse you can replace x by y, so by replacing x by y, the above equation becomes

y =[tex]\pm\sqrt{x+36}[/tex]

Answer:

(–7x + 4)(–7x – 4) Sign changes in the middle of both parenthesis , so this will result in difference of squares

Step-by-step explanation:

The formula for difference of squares

[tex]a^2 - b^2 =(a+b)(a-b)[/tex]

(–7x + 4)(–7x + 4) both parenthesis having same terms so this will not result in difference of squares

(–7x + 4)(4 – 7x) both parenthesis having same terms so this will not result in difference of squares

(–7x + 4)(–7x – 4) Sign changes in the middle of both parenthesis , so this will result in difference of squares

(–7x + 4)(7x – 4) sign changes for both terms in both parenthesis so this will not result in difference of squares

The measure of angle 4 is 40°. That is, m4 = 40°. The correct option is the first option m4 = 40°

From the diagram, we can observe that angles 6 and 7 are vertically opposite angles.

From one of the angle theorems, we have that vertically opposite angles are equal

That means,

measure of ∠ 6 = measure of ∠ 7

From the question,

we have that, m6 = (11x + 8)° and m7 = (12x – 4)°

Since, the measures of angles 6 and 7 are equal, then we can write that

(11x + 8)° = (12x – 4)°

Now, determine the value of x, we will solve the equation

11x + 8 = 12x – 4  

First, subtract 11x from both sides

11x - 11x + 8 = 12x - 11x - 4

8 = x - 4

Now, add 4 to both sides

8 + 4 = x -4 +4

12 = x

∴ x = 12

Now, we will determine the measure of ∠6

m ∠6 = (11x + 8)°

Put x = 12

∴ m ∠6 = (11(12) + 8)°

m ∠6 = (132 + 8)°

m ∠6 = 140°

To determine the measure of ∠4, m4, we will first determine the measure of ∠8.

From the diagram,

m ∠6 + m ∠8 = 180° (Sum of angles on a straight line)

∴ 140° + m ∠8 = 180°

Then,

m ∠8 = 180° - 140°

m ∠8 = 40°

From the diagram, we can observe that angles 4 and 8 are corresponding angles.

Also, from one of the angle theorems, we have that corresponding angles are equal.

Hence, the measure of ∠ 4 equals the measure of ∠ 8.

From above, m ∠8 = 40°

∴ m ∠4 = 40°

Hence, the measure of angle 4 is 40°. That is, m4 = 40°. The correct option is the first option m4 = 40°

The function representing the relationship between the number of employees and the number of days it takes to complete the task is[tex]\[ e \times d = 16 \][/tex].

To represent the relationship between the number of employees (e) and the number of days (d) it takes to complete a task, we can use the formula:

[tex]\[ e \times d = k \][/tex]

where  k is a constant representing the amount of work to be done.

Given the information that 4 employees complete the task in 4 days, and 2 employees complete it in 8 days, we can set up two equations using the formula:

[tex]\[ 4 \times 4 = k \][/tex]

[tex]\[ 2 \times 8 = k \][/tex]

Now, solve each equation for ( k):

[tex]\[ 4 \times 4 = 16 \][/tex]

[tex]\[ 2 \times 8 = 16 \][/tex]

Since both equations give us the same constant ( k ), we can conclude that:

[tex]\[ e \times d = 16 \][/tex]

Therefore, the function representing the relationship between the number of employees and the number of days it takes to complete the task is:

[tex]\[ e \times d = 16 \][/tex]

3.2,3.4 and 3.6

Step-by-step explanation:

We have to find decimals between 3.0 and 3.8 with an interval of 0.2 between each pair of decimals

3.0

3.0+0.2= 3.2

3.2+0.2= 3.4

3.4+0.2= 3.6

3.6+0.2= 3.8

Hence, decimals between 3.0 and 3.8 with an interval of 0.2 between each pair of decimals are:
