Given that x is multiplied by 7 = 21 Then

7 * x = 21

or x = 21/ 7

Therefore x = 3.

Answer:

Solution,

here,

x+7=21

x=21-7

Therefore,x=14

Answer:

1) Please find attached the given plot and sketch of the points created with Microsoft Word

2) The correct option is;

A. AA Similarity Postulate

Step-by-step explanation:

1) Please find attached the given plot and sketch of the points created with Microsoft Word

2) The given parameters are;

The coordinates of the points are A(0, 0), B(1, 0), C(1, 2), D(2, 0) and E(2, 4)

Therefore, we have;

The length of segment AB = 1

The length of segment BC = 2

The length of segment AD = 2

The length of segment DE = 4

Therefore, we have;

∠ABC = ∠ADE = 90°

∠BAC = = artctan(2/1) = ∠DAE = artctan(4/2) = 63.435°

Therefore, ΔABC and ΔADE are similar by AA Similarity Postulate

A. 0.499 ≤ x ≤ 0.501

B. x ≤ 0.49 or x ≥ 0.51

C. x ≤ 0.499 or x ≥ 0.501

D. 0.49 ≤ x ≤ 0.51

I believe it was C

Answer:

We conclude that a function is defined as having only one corresponding y-value for each x-value.

Hence, option (C) is true.

Step-by-step explanation:

We know that A function is a certain relationship is defined as having only one corresponding y-value for each x-value.

Considering the function

Here,

Considering the table

x                      y

1                      2

2                     3

3                     4

4                     5

The values in the table satisfy the function y = x+1.

It is clear from the table that the function has only one corresponding y-value for each x-value. In other words, there is no repetition of 'x' value.

Therefore, we conclude that a function is defined as having only one corresponding y-value for each x-value.

Hence, option (C) is true.

Answer:90

Step-by-step explanation:

Answer: $90

Step-by-step explanation:

You can set up a proportion.

$54 = 3 tickets

x = 5 tickets

To find x, multiply 54 and 5.

54 × 5 = 270

Then divide 270 by 3.

270 ÷ 3 = $90

Since we figured out x = $90, this means that it costs $90 for 5 tickets.

Answer:

They meet in 2.22 hours.

Step-by-step explanation:

We can find the time at which Reagan and Nathan meet by equaling the time as follows:

[tex] v_{R} = \frac{x_{R}}{t} [/tex]  

[tex] x_{R} = v_{R}t [/tex]    (1)      

[tex] v_{N} = \frac{x_{N}}{t} [/tex]  

[tex] x_{N} = v_{N}t [/tex]   (2)

Where R is for Reagan and N for Nathan.

Knowing that:

[tex] x_{R} + x_{N} = 40 mi [/tex]

By adding equations (1) and (2) we have:

[tex] x_{R} + x_{N} = v_{R}t + v_{N}t [/tex]

[tex] t = \frac{x_{R} + x_{N}}{|v_{R}| + |v_{N}|} = \frac{40 mi}{8 mi/h + 10 mi/h} = 2.22 h [/tex]

Therefore, they meet in 2.22 hours.        

I hope it helps you!

Answer:

The equation of the line is -5/4

Step-by-step explanation:

Answer:

the slope is 1

Step-by-step explanation:

Answer:

#1:  A

#2:  2

I apologize if its wrong

Answer: A, 5

Explanation:

Simply create an slope-intercept equation using the given information. The initial fee is $5, which is the y-intercept and $2.75 every stop, which is our slope. The equation is y = 2.75x+5. Since this is an inequality and she's looking for the most amount of stops she can take before maximizing her budget, it needs to be a less than or equal to sign. Change the equation to be 5+2.75S≤21. Subtract 5 from both sides to get 2.75S≤16. Divide 2.75 to both sides to get S≤5.82. This would be estimated to around 5 stops, which would be the largest amount of stops.

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

uhhh d????

Step-by-step explanation:

Graph D represents the  linear inequality x – 2y > –6.

The given inequality is x – 2y > –6.

We rearrange the inequality as y < (1/2)x + 3

Now we have the inequality in slope-intercept form, y < mx + b, where m is the slope (1/2) and b is the y-intercept (3).

To graph this inequality, you can start by plotting the y-intercept, which is the point (0, 3).

The slope of the graph is 1/2.

However, the inequality is y < (1/2)x + 3, which means the shaded region is below the line.

Hence, graph D represents the  linear inequality x – 2y > –6.

Proportional and linear functions are almost identical in form. The only difference is the addition of the “b” constant to the linear function. Indeed, a proportional relationship is just a linear relationship where b = 0, or to put it another way, where the line passes through the origin (0,0).
