Which equation in standard form has a graph that passes through the point (5, −2) and has a slope of 72 ?

aalyn [17]

Given:

Consider the graph passes through the point (5, −2) and has a slope of $\dfrac{7}{2}$ .

To find:

The equation of graph in standard form.

Solution:

Point slope form of a line is

$y-y_1=m(x-x_1)$

where, m is slope and $(x_1,y_1)$ is the point lies on the line.

Slope is $\dfrac{7}{2}$ and graph passes through (5,-2), so the equation of line is

$y-(-2)=\dfrac{7}{2}(x-5)$

$y+2=\dfrac{7}{2}(x-5)$

Multiply both sides by 2.

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

$2y+4=7x-35$

$4+35=7x-2y$

$39=7x-2y$

The required equation is $7x-2y=39$ .

Therefore, the correct option is B.

Julia is saving money for the down payment on a car. She plans to save for one year. Her parents have offered to contribute $50

denis23 [38]

Answer:

$12x+600=2700$

$175

Step-by-step explanation:

Let x represent money saved by her in one month.

So money saved by her in one year (12 months) would be $12x$ .

We can represent our given information as:

$12x+600=2700\\12x=2700-600\\12x=2100\\x=\frac{2100}{12}\\x=175$

Therefore, she needs to save $175 per month.

Calcular el volumen en m3 de la esfera en el que el área de uno de sus círculos maximos es 36pim2

Strike441 [17]

Answer:

The volume of the sphere is $V=288\pi\ m^3$

Step-by-step explanation:

<u><em>The question in English is</em></u>

Calculate the volume in m^3 of the sphere in which the area of one of its maximum circles is 36pi m^2

we know that

The radius of the maximum circle in the sphere is equal to the radius of the sphere

Step 1

Find the radius of the maximum circle

The area of the circle is

$A=\pi r^{2}$

we have

$A=36\pi\ m^2$

substitute and solve for r

$36\pi=\pi r^{2}$

Simplify

$36=r^{2}$

take the square root both sides

$r=6\ m$

Step 2

Find the volume of the sphere

The volume of the sphere is

$V=\frac{4}{3}\pi r^{3}$

substitute the value of r

$V=\frac{4}{3}\pi (6)^{3}$

$V=288\pi\ m^3$
