Answer:

$y=15x$

Step-by-step explanation:

We are asked to find the equation for given quantities, when y varies directly as x.

We know that the equation of two proportional quantities are in form $y=kx$ , where k represents constant of proportionality.

Let us find constant of proportionality by substituting $x=24$ and $y=360$ in above equation.

$360=24k$

$\frac{360}{24}=\frac{24k}{24}$

$15=k$

Therefore, our required equation would be $y=15x$ .

Y = kx
360 = 24k
k = 15
y = 15x

Answer:

1/12

Step-by-step explanation:

You are close but 1/27 includes people who did not study but still passed. If you want a singular value you should look at the value for the for only the people who studied even if they passed.

Help! Hurry! NO SPAM!!!! I will mark brainliest if you get it correct, and show your work. Identify the equation for the circle

kotegsom [21]

First we compute the distance between the center and the given point which is exactly the radius

r =

$\sqrt{(x2 - x1) + (y2 - y1)} = \sqrt{9 - 3 + 11 - 7} = \sqrt{10}$

Now that we know the center and the radius, we can write the equation of a circle with given radius and center:

${(x - h)}^{2} + {(y - k)}^{2} = {r}^{2}$

where (h,k) represent the coordinates of the center (3,7).

We substitute and obtain

${(x - 3)}^{2} + {(y - 7)}^{2} = { \sqrt{10} }^{2} \\ {(x - 3)}^{2} + {(y - 7)}^{2} = 10 \\ {x}^{2} - 6x + 9 + {y}^{2} - 14y + 49 = 10 \\ {x}^{2} + {y}^{2} - 6x - 14y + 48 = 0$

Which function represents a reflection of f(x) = 2(0.35)x over the y-axis?

Zina [86]

The function that is a reflection of f(x) over the y-axis is h(x) = 2(0.35)^(-x)

<h3>How to determine the reflection?</h3>

The equation is given as:

f(x) = 2(0.35)^x

The reflection of a function over the y-axis is :

f'(x) = f(-x)

So, we have:

f(-x) = 2(0.35)^(-x)

From the list of options, we have

h(x) = 2(0.35)^(-x)

Hence, the function that is a reflection of f(x) over the y-axis is h(x) = 2(0.35)^(-x)
