Determine if the function is linear. if it is, find the rate of change

Use the Pythagorean theorem:

70^2 = 42^2 + width^2

4900 = 1764 + width ^2

Subtract 1764 from both sides

3136 = width^2

Take the square root of both sides

Width = 56 inches

Hello!

Answer: A real life example would be if you would add 100 dollars in a bank account and then, subtract the 100 dollars from that account.

The equation used would be 100 + (-100) or in a simpler version 100 - 100 (They both mean the same thing!)

Hope this helps! :)))

Answer:

Always True (infinite)

Step-by-step explanation:

If you try and isolate the x variable... you will end up with the equation 0 = 0

Any time you end up with the equation 0 = 0, there are an infinite number of solutions.

Answer:

y = 12  when x = 6/7.

Unless you give a formula (function, or equation) that specifies their relationship, one cannot find x when y equals something else.

x+20=2x

therefore x=20

Answer:

1) Infinitely many solutions.

2) No real solutions.

3) (-1, 2)

Step-by-step explanation:

The solutions of a system of linear equations is whenever the two lines intersect.

However, if the two lines never intersect (they are parallel), then there are no solutions.

And if the two lines are the same line, then there are infinitely many solutions.

First Graph:

The two lines are exactly the same.

Hence, there are infinitely many solutions.

Second Graph:

The two lines are parallel. They will never intersect each other.

Therefore, there are no real solutions.

Third Graph:

The two lines intersect at the point (-1, 2).

Hence, there is only one solution and it is (-1, 2).

Step-by-step explanation:

Answer:

A) x=8 and angle ABC=115 degrees

Step-by-step explanation:

the lines are parallel, meaning the angles are congruent.

you can set up the equation (15x-5)=(10x+35) and simplify.

1. separate variable by subtracting 10x on both sides to get (5x-5)=(35)

2. add 5 on both sides to get 5x=40

3. divide both sides by 5 to get x=8

4. plug x=8 into original function (10x+35) to get (10(8)+35) which equals 115 degrees

Answer:

Wow that's hard to look at. But, when zooming in, we can see that the arrow is closer to 116 degrees, so that is the answer.

Step-by-step explanation:

Notice that the angle/arrows is opening up from right to left, so it will be greater than 90 degrees. The arrow is a little bit more than 115 degrees, so it has to be 116 degrees.

Answer:

The ball's speed is 57.5 m/s

Step-by-step explanation:

Given;

distance between the tee and the green, d = 230 m

time taken for the ball to travel from the tee to the green, t = 4 seconds

The speed of the ball is given as;

speed = total distance traveled / total time taken

speed = 230 m / 4 s

speed = 57.5 m/s

Therefore, the ball's speed is 57.5 m/s

False because they are congruent

Step-by-step explanation:

Assuming the trend continues, there will be 30 students on the 6th row of the bleachers.

According to the question,

We have the following details:

Number of students in 1st row = 10

Number of students in 2nd row = 14

Number of students in 3rd row = 18

Number of students in 4th row = 22

Now, if we carefully observe the arrangement made by the chorus teacher, we will observe that the arrangement has a pattern.

It is to be noted that with each row 4 students are increasing.

For example, in 2nd row the number of students is 14 (4 more than the previous row), in 3rd row the number of students is 18 (4 more than the previous row), etc.

Now, we have to find the number of students in 6th row. So, first we need to find the number of students in 5th row.

Number of students in 5th row = number of students in 4th row + 4

Number of students in 5th row = 22+4

Number of students in 5th row = 26

Now,

Number of students in 6th row = number of students in 5th row + 4

Number of students in 6th row = 26+4

Number of students in 6th row = 30

Hence, there are 30 students on the 6th row of the bleachers.

Answer:

Population in 1950 was 4,100,000

Step-by-step explanation:

Equation: 5x + 2,000,000 = 22,500,000

Subtract 2,000,000 from each side: 5x = 20,500,000

Divide each side by 5: x = 4,100,000

The value of the variable 'c' is 10. Then the perfect square trinomial is (x + 10)².

A perfect square trinomial formulation can be created by taking the binomial equation's squared. If and then only if a trinomial satisfying the criterion b² = 4ac has the form ax² + bx + c, it is indeed a perfect square.

The trinomial is given below.

⇒ x² + 20x + c

The value of 'c' must be equal to half of the square of the coefficient of x. Then we have

c = [1/2 × (20)]²

c = (10)²

c = 100

Then the perfect square trinomial is written as,

x² + 20x + 100 = (x + 10)²

The value of the variable 'c' is 10. Then the perfect square trinomial is (x + 10)².

Answer:

66 gallons

Step-by-step explanation:

Given that initially 160 gallons of a solution containing 12% salt.

So, the initial amount of salt = 12% of 160 = 12/100 x 160 = 19.2 gallons.

Let x gallons of water get evaporated so that the remaining solution contains 20% salt.

The remaining amount of solution = 160-x gallons.

As the initial amount of salt is still in the solution which is equal to 20% of the remaining solution, so

19.2 = 20% of (160-x)

[tex]\Rightarrow 19.2 = \frac {20}{100}\times (160-x) \\\\\Rightarrow 19.2 = \frac {1}{5}\times (160-x) \\\\\Rightarrow 19.2 \times 5= 160-x \\\\\Rightarrow 96= 160-x \\\\\Rightarrow x= 160-96 \\\\[/tex]

[tex]\Rightarrow x= 66[/tex] gallons

Hence, 66 gallons of water must be evaporated to get a 20% salt solution.
