Express it in slope-intercept form.

GREYUIT [131]

Answer:

y = (2/3)x -1

Step-by-step explanation:

The line crosses the y-axis at -1, so that is the y-intercept.

From that point. the next grid intersection is 3 units to the right and 2 units up, so the slope is ...

m = rise/run = 2/3

The slope-intercept form of the equation of a line is ...

y = mx +b . . . . . where m is the slope (2/3) and b is the y-intercept (-1)

Your line has equation ...

y = (2/3)x -1

The volume of the sphere is 904.32 m. To the nearest meter, what is the radius of the sphere????? Use 3.14 for pi.

Rus_ich [418]

Answer:

Step-by-step explanation:

The formula for the volume of a sphere is $\frac{4}{3} \pi r^3$ . Plugging in the values that you are given, you get:

$904.32=\frac{4}{3}\pi r^3$

Dividing both sides by pi or 3.14:

$288=\frac{4}{3}r^3$

Dividing both sides by 4/3:

$216=r^3$

Taking the cube root of both sides:

$r=6$

Hope this helps!

-15X - 40 = 23 - 8 This is the problem and I am totally lost

Elena-2011 [213]

-15x-40=15
then add 40 to both sides to get the constants on 1 side and variables on the other
-15x=25
now you just divide by -15
x = -1.67 or x = -1/3

If 1/8(8x+15)24, what is the value of x?

Lelechka [254]

Answer:

$x=22.125$ or $x=\frac{177}{8}$

Step-by-step explanation:

The correct equation is

$1/8(8x+15)=24$

solve for x

Multiply by 8 both sides to remove the fraction

$(8x+15)=192$

subtract 15 both sides

$8x=192-15\\8x=177$

divide by 8 both sides

$x=\frac{177}{8}$

$x=22.125$
