The sum of 5 and c is greater than or equal to - 28.

The total number of labels collected by the students in the third month is equal to 525 by the equation 3 x + x = 2100.

Let the number of labels collected in the first two months be 3 x.

We are given that the number of labels collected in the first two months was three times the number of labels collected in the third month.

So, the number of labels collected in the third month = 3 x / 3 = x

Now, we are also given that:

The total number of labels collected by the students at the school = 2100.

So, we get the equation as:

3 x + x = 2100

4 x = 2100

x = 2100 / 4

x = 525 labels.

Therefore, we get that, the total number of labels collected by the students in the third month is equal to 525 by the equation 3 x + x = 2100.

Answer:

x = -7

Let the first integer be x.

Given the next two integers are consecutive, it would be: x+1, x+2

The problem states: "4 more than the smaller number plus twice the 3rd number is 7 less than the 2nd number."

Translating English to Algebra, you'll get:

(x + 4) + 2(x + 2) + 7 = x + 1

x + 4 + 2x + 4 + 7 = x + 1

3x + 15 = x + 1

2x = -14

x = -7

That would be the third option.

18 units is the distance between points F and G.

Assume a line with points marked on it.

Center is 0.

Left to the point 0 indicates negative numbers.

Right to the point 0 indicates positive numbers.

Given,

A number line is marked with negative 10 to positive 14.

Point F is placed at negative 6.

Point G is placed at positive 12.

We have to determine the distance between points F and G.

We can consider the number line.

From 0 to negative 10 there were 10 units.

From 0 to positive 14 there were 14 units.

Now points F and G,

From 0 to negative 6 there were 6 units.

From 0 to positive 12 there were 12 units.

We can add this together:

That is,

6 units + 12 units = 18 units.

Therefore, the distance between points F and G is 18 units.

Step-by-step explanation:

it is always the same. the slope is (y coordinate change / x coordinate change) when going from one point on the line to another.

the direction itself does not matter, but it is important to use the same direction for the x and the y comparison.

I prefer to go from left to right, so let's go from

(-3, 4) to (2, -4).

x changes by +5 (from -3 to 2).

y changes by -8 (from 4 to -4).

the slope is

The measure of the complement of angle K is (78 - 6x)°. The correct option is D. (78 − 6x)°

From the question, we are to determine the complement of the given angle measure

From the given information, the measure of angle K (m ∠K) is (6x + 12)°

NOTE: If two angles are complementary, the measures of the angles sum up to 90°

Let the complement of angle K be angle L.

Thus,

∠K + ∠L = 90°

(6x + 12)° + ∠L = 90°

6x° + 12° + ∠L = 90°

∠L = 90° - 12° - 6x°

∠L = 78° - 6x°

∠L = (78 - 6x)°

Hence, the measure of the complement of angle K is (78 - 6x)°. The correct option is D. (78 − 6x)°

Random assignment means participants have an equal chance of being in the control group or in the experimental group.

Assignment refers to putting people into experimental or control group. In this, the Random assignment involves dividing the participants into two groups through randomization. That is, selection is on random. Tis method provides equal chance for the participants to be in the experimental or control group.

This kind of assignment will be unbiased and the participants in two groups does not differ in any way. So random assignment makes the experiment and control group equivalent. Also this makes the experimental study more accurate, acceptable and scientific too.

Answer:

2n² + n

Step-by-step explanation:

Given sequence:

3, 10, 21, 36, ...

Work out the first differences between terms:

[tex]3 \underset{+7}{\longrightarrow} 10 \underset{+11}{\longrightarrow} 21 \underset{+15}{\longrightarrow} 36[/tex]

As the first differences are not the same, work out the second differences.

[tex]7 \underset{+4}{\longrightarrow} 11 \underset{+4}{\longrightarrow} 15[/tex]

As the second differences are the same, the sequence is quadratic and will contain an n² term.

The coefficient of n² is always half of the second difference. Therefore, as the second difference is 4, the coefficient of n² is 2.

To work out the nth term of the sequence, write out the numbers in the sequence 2n² and compare with the given sequence:

[tex]\begin{array}{|l|c|c|c|c|}\cline{1-5} n & 1 & 2 & 3 & 4 \\\cline{1-5} 2n^2 & 2 & 8 & 18 & 32\\\cline{1-5} \sf Operation & +1 & +2& +3& +4\\\cline{1-5} \sf Sequence & 3 & 10 & 21 & 36\\\cline{1-5}\end{array}[/tex]

10. Debra is 1 year old now.

The situation is modeled by the following linear function:

P(n) = 2.75 + 4.25n.

We have that P(n) = 24, hence we have to solve for n.

24 = 2.75 + 4.25n.

n = (24 - 2.75)/4.25

n = 5.

Answer: x<45.9?

Step-by-step explanation:

25.5+24.3+24.8+23.5=98.1

So (x+98.1)/6<24?

x<45.9?

The answer to the inequality is expressed as x< 1 and x< -4

Inequalities are mathematical expressions having both sides unequal or rather not equivalent to each other.

Given the inequality;

4x (x+3) < -24

First, expand the bracket

4x² + 12x < -  24

Let's turn to quadratic inequality

4x² + 12x - 24 < 0

Factorize further

4 ( x² + 3x - 4) < 0

4 ( x² + 4x - x - 4) < 0

4 ( x(x + 4) - 1 (x + 4) ) < 0

4(x - 1) ( x + 4) < 0

expand the bracket

4x - 4 < 0

x < 1

And

4x + 16 < 0

x < -4

The new percentage of broth to solution 25/60 is 41.67

Broth, also known as bouillon is a savory liquid made of water in which meat, fish or vegetables have been simmered for a short period of time .It can be eaten alone, but it is most commonly used to prepare other dishes, such as soups.

Commercially prepared liquid broths are available, typically chicken, beef, fish, and vegetable varieties. Dehydrated broth in the form of bouillon cubes were commercialized beginning in the early 20th century.

Broths have been used as a nutrition source for the sick in Great Britain since at least the early 1700s, such as for dysentery patients

Let,

60 represents the 100% of the broth to solution

25 represents the x percentage of the broth to solution

Now,

Solving for the 25 which represents the x percentage of the broth to solution.

25/100 = x/100*

25/60 = x/100*x

25(100) = 60x

x = 2500/60

x = 41.67

Therefore,

25 represents the 41.67 percentage of the broth to solution.

3) h (x)

Step-by-step explanation:

Answer:

For f (x):

f (x) = (x + 3) ^ 2 - 2

For x = -1

f (-1) = (-1 + 3) ^ 2 - 2

f (-1) = (2) ^ 2 - 2

f (-1) = 4 - 2

f (-1) = 2

For x = 3

f (3) = (3 + 3) ^ 2 - 2

f (3) = (6) ^ 2 - 2

f (3) = 36 - 2

f (3) = 34

g (-1) = -1/2 - 3/2

g (-1) = -4/2
