If 21x = 63y, what is the ratio of x to y expressed in simplest form? Please show work.

1 answer:

8 0

I believe these would be your steps:
21x = 63y

divide by a common factor of 7

3x = 9y

divide by a common factor of three

x = 3y is your simplest ratio

Hope this helps!

Here's the question, please help!

nata0808 [166]

Answer:

None of these

Step-by-step explanation:

To convert the parametric curve into Cartesian form,
rewrite the equation for $x$ to make $\sin t$ the subject:

$x=2\sin t$

$\implies \sin t=\dfrac{x}{2}$

Substitute this into the given equation for $y$ :

$\begin{aligned}y & =3 \sin t\\\implies y & = 3 \left(\dfrac{x}{2}\right)\\y& = \dfrac{3}{2}x\end{aligned}$

Therefore, the Cartesian form of the parametric curve is:

$y=\dfrac{3}{2}x$

Further Information

$\dfrac{x^2}{2}+\dfrac{y^2}{3}=1 \quad \textsf{is the equation of a vertical ellipse}$

$\textsf{with center (0, 0), co-vertex }\sf \sqrt{2}, \textsf{ and vertex }\sqrt{3}$

$x^2+y^2=6 \quad \textsf{is the equation of a circle}$

$\textsf{with center (0, 0) and radius }\sf \sqrt{6}$

$3x^2+2y^2=1 \quad \textsf{is the equation of a vertical ellipse}$

$\textsf{with center (0, 0), co-vertex }\sf \dfrac{\sqrt{3}}{3}, \textsf{ and vertex }\dfrac{\sqrt{2}}{2}$

bogdanovich [222]

Answer:

Step-by-step explanation:

4x-40=7(-2x+2) multiply inside the parenthesis with 7

4x - 40 = -14x + 14 export like terms to the same side of equation

4x + 14x = 14 + 40 add like terms

18x = 54 divide both side by 18

x = 3

Solve this problem on paper using all four steps. Enter each answer separated by a comma, in numerical order.

salantis [7]

Answer:

27, 28, 29 and 30

Step-by-step explanation:

Let the integers be:

n, n + 1, n + 2 and n + 3

Their sum is 114:

n + n + 1 + n + 2 + n + 3 = 114

Solving for n:

4n + 6 = 114
4n = 108
n = 108/4
n = 27

The numbers are: 27, 28, 29 and 30
