Answer and Step-by-step explanation:

To find all equations where x = 3 is a solution, solve all equations for x and see if it is equal to 3.

A. x - 3 = 0

x = 3

B. 1 + x = 2

x = 1

C. 9 - x = 3

x = 6

D. 6 = 2x

x = 3

E. $\frac{1}{5} x = 3$

x = 15

F. $x^2 = 9$

x = 3

A, D, and F are the answers.

Convert the following equation to cartesian coordinates. describe the resulting curve.

enyata [817]

Answer:

The rules for change of coordinates are:

r = √(x^2 + y^2)

θ = tan(y/x)

and:

x = r*cos(θ)

y = r*sin(θ)

1) Now we have the equation:

r = (9/7)*cos(θ) + 2*sin(θ)

Let's multiply both sides by r:

r^2 = r*( (9/7)*cos(θ) + 2*sin(θ) )

r^2 = (9/7)*r*cos(θ) + 2*r*sin(θ)

Now we can replace:

r*cos(θ) by x and r*sin(θ) by y

r^2 = (9/7)*x + 2*y

And we know that:

r = √(x^2 + y^2)

then:

r^2 = x^2 + y^2

So we can replace that in our equation:

x^2 + y^2 = (9/7)*x + 2*y

This is the equation in cartesian coordinates.

2) Now we want to describe the curve.

We can rewrite this as:

[x^2 - (9/7)*x] + [ y^2 - 2*y] = 0

Now we can complete squares:

So we need to add and subtract:

(4.5/7)^2 and 1^2

[x^2 - 2*(4.5/7)*x + (4.5/7)^2 - (4.5/7)^2] + [ y^2 - 2*y + 1 - 1] = 0

(x - (4.5/7) )^2 + (y - 1)^2 - 1 - (4.5/7) = 0

(x - (4.5/7) )^2 + (y - 1)^2 = 1 + 4.5/7

So this is the equation of a circle, centered at:

( 4.5/7, 1) and with a radius √(1 + 4.5/7)

The circle below has a center D and its diameter is 10 feet. Given that m angle A D B equals 35 degree, find the length of major

Allushta [10]

The length of major arc ACD in the circle with center D is given as (325/36)π feet

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

The length of major arc ACD = [(360 - 35) / 360) * 2π(10/2) = (325/36)π feet

The length of major arc ACD in the circle with center D is given as (325/36)π feet

When the y-intercepts of a line is 0, the relationship is....

Mnenie [13.5K]

Answer:

I am going to assume you mean the relationship between x and y.

If the y-intercept is 0, that means the point is on the origin.

So x and y are equal to each other. they are both zero
