The Table Represents Some Points On The Graph Of A Linear Function.Which Equation Represents The Same

Answers

Answer 1

The equation that represents the same relationship is equation 1: x-2y-1=0

How to find the equation?

We should know that an equation is a mathematical statement that shows the equality of two sides o a statement.

From the given equation:

x-2y-1=0

If we input the various values of x such as -5, 7,31,42 into the equation we are going to obtain the corresponding values of y as indicated in the table

Rewrite the equation

x-1=2y

⇒2y=x-1

=2y=-5-1

y=-3

Also, 2y=7-1

2y=6

y=3

Input the value 31 into the equation or x

2y=31-1

2y=30

y=15

Input the value 45 or x in the equation

2y=45-1

2y=44

y=22

Which equation represents the linear relationship between the x-values and the y- values in the table

Answers

The equation of a line that represents the table is y = 6x - 5.

What are lines and their slopes?

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

To obtain the linear equation first we need slope(m) = (y₂ - y₁)/(x₂ - x₁)

= (1 + 11)/(1 + 1) = 12/2 = 6.

Now, we'll take any one of these coordinate points and construct an equation in slope-intercept form,

- 11 = 6(-1) + b.

- 11 = - 6 + b.

b = - 5.

∴ y = 6x - 5 is our equation.

A Circle Has An Equation of (x - 5)^2 + (y - 1)^2 = 30. What Is The Center And Radius Of The Circle?

Answers

the center of the circle is at (5, 1) and the radius is approximately 5.48 units.

Why it is and what is perimeter of a circle?

The standard equation of a circle with center (a,b) and radius r is:

(x - a)²2 + (y - b)²2 = r²2

Comparing this equation to the given equation, we can see that the center of the circle is (5, 1) and the radius is the square root of 30. Therefore, the center of the circle is at (5, 1) and the radius is approximately 5.48 units.

The perimeter of a circle is also known as its circumference, and it can be calculated using the formula:

C = 2πr

where C is the circumference, r is the radius of the circle, and π (pi) is a mathematical constant approximately equal to 3.14159.

Alternatively, you can also use the formula:

C = πd

where d is the diameter of the circle.

So if you know the radius or diameter of a circle, you can use either of these formulas to calculate its circumference (perimeter).

Find the equation of the line passing through pl7, -2) and (5, 3).​

Answers

The equation of the line passing through (7, -2) and (5, 3) is 5x + 2y - 31 = 0.

What is two point equation form?

The equation of a line in the coordinate plane can be expressed in two point form. Depending on the facts at hand, there are different ways to find a line's equation. One of the ways is the two-point form. When two locations along a line are known, this is used to determine the equation of the line. Slope intercept form, intercept form, point slope form, and others are crucial ways to describe a line equation.

The equation of the line passing through two points is

(y - y₁) / (y₂ - y₁) = (x - x₁) / (x₂ - x₁)

Here, (x₁,y₁) ∈ (7, -2)

(x₂, y₂) ∈ (5, 3).

y - (-2) / 3 -(-2) = x - 7/ 5 - 7

(y + 2) / 5 = x-7 / -2

-2y - 4 = 5x - 35

5x + 2y - 31 = 0

The value of the piecewise function h(x) at x = 2 is (b) -1

How to evaluate the piecewise function

From the question, we have the following parameters that can be used in our computation:

Part 1:

h(x) = x cubed for x less than negative 3

Part 2:

h(x) = 2 times x squared minus 9 for negative 3 is less than or equal to x which is less than 4,

Part 3

h(x) = 5 times x plus 4, for x greater than or equal to 4

When the above statements are represented properly, we have the following equations

Part 1: h(x) = x³ for x < -3

Part 2: h(x) = 2x² - 9 for -3 ≤ x < 4

Part 3: h(x) = 5x + 4, for x ≥ 4

To calculate the function h(2), we use the domain -3 ≤ x < 4

So, we have the following function

h(x) = 2x² - 9

Substitute the known values in the above equation, so, we have the following representation

h(2) = 2(2)² - 9

Evaluate the expression

h(2) = -1

Hence, the value is (b) -1

How to find the g[f(0)] of the function?

A function is a relationship between inputs where each input is related to exactly one output

Given:  f(x)= 2x+8, g(x)= 5x-2/4 and h(x)= 2x+6/x

(a) g[f(0)]

Substitute x = 0 into  f(x)= 2x+8 to get f(0)

f(0) = 2(0)+8 =8

g[f(0)] =  g(8)

Substitute x = 8 into g(x)= 5x-2/4 to get g[f(0)]

g[f(0)] =  g(8)

g[f(0)]  = 5x-2/4

g[f(0)]  = 5(8)-2/4 = 9.5

b) f(-5)

Substitute x = -5 into  f(x)= 2x+8 to get f(-5)

 f(x)= 2x+8

f(-5)= 2(-5)+8 = -2

c) f[h(3)]

h(x)= 2x+6/x

h(3) = 2(3)+6/3 = 4

f[h(3)] = f[4]

f[4] = 2(4)+8 = 16

f[h(3)]  = 16

d) h°f(x)

h°f(x)  = h(2x+8)  

Since h(x)= 2x+6/x

h°f(x) = 2(2x+8) +6/x

h°f(x) = 4x+16+6/x = (4x+22)/x

e) h⁻¹(x)

h(x)= 2x+6/x

Let y = 2x+6/x

x = 6/(y-2)

x = h⁻¹(y)

h⁻¹(x) = 6/(x-2)

c) solve the quadratic equation to find possible values of x
d) if told that the two numbers are positive numbers what are the values of the two original numbers?

Answers

The values of the two original numbers are 7 and 9.

Two numbers when multiplied equal 63 if one number is x and the other number is greater than x by 2.

As per the given phrase, the information given in equation form is as

x × (x + 2) = 63

It expresses as a quadratic equation:

x² + 2x - 63 = 0

Solve the quadratic equation to find possible values of x

x² + 9x - 7x - 63 = 0

x(x + 9) - 7(x + 9) = 0

(x + 9)(x - 7) = 0

(x + 9) = 0 and (x - 7) = 0

x = -9 and x = 7

Since we were told that the two numbers are positive numbers so take x = 7.

Thus, the values of the two original numbers are 7 and 9.
