15. Solve for the specified variable:<br> -<br> х<br> +<br> 7 8<br> - 10; for y.

Andreyy89

Answer:

$y=80-\frac{8x}{7}$

Step-by-step explanation:

15). Given equation is,

$\frac{x}{7}+ \frac{y}{8}=10$

Multiply the equation by 8,

$8(\frac{x}{7}+ \frac{y}{8})=10\times 8$

$\frac{8x}{7}+y=80$

Subtract $\frac{8x}{7}$ from both the sides of the equation,

$\frac{8x}{7}+y-\frac{8x}{7}=80-\frac{8x}{7}$

$y=80-\frac{8x}{7}$

Therefore, value of the variable 'y' will be,

$y=80-\frac{8x}{7}$

The picture below illustrates a special type of conic section called

Rufina [12.5K]

Answer:

A

Step-by-step explanation:

The picture below illustrates a hyperbola.

The intersecting plane does not pass through the vertex of a right circular cone (the vertex of the cone is the point where two nappes meet).

As you can see from the diagram, the plane intersects both nappes of a right circular cone.

Hence, correct option is option A: The plane does not pass through the vertex and intersects both nappes of a right circular cone.

The n number of homeruns hit during the regular season by a certain baseball player can be modeled by the function n(x) =3/4x, w

sukhopar [10]

Answer:

The average rate of change is equal to $\frac{3}{4}\frac{homeruns}{game}$

Step-by-step explanation:

we have

$n(x)=\frac{3}{4}x$ -----> this is a linear direct variation

we know that

The rate of change of a linear variation is a constant

The rate of change of a linear variation is equal to the slope of the line

In this problem the slope of the line is equal to $m=\frac{3}{4}\frac{homeruns}{game}$

therefore

The average rate of change is equal to $\frac{3}{4}\frac{homeruns}{game}$

<u>Verify</u>

the average rate of change is equal to

$\frac{n(b)-n(a)}{b-a}$

In this problem we have

$n(a)=n(12)=\frac{3}{4}(12)=9\ homeruns$

$n(b)=n(60)=\frac{3}{4}(60)=45\ homeruns$

$a=12\ games$

$b=60\ games$

Substitute

$\frac{45-9}{60-12}=\frac{3}{4}\frac{homeruns}{game}$
