She should have added 2 to both sides of the equation instead of subtracting 2.

2x -2 = 14

Add 2 to both sides:

2x = 16

Divide both sides by 2:

x = 8

Find the volume of a sphere with a surface area of 3600pi in squared.
Anna71 [15]

Answer:

36000pi

Step-by-step explanation:

V = 4/3*pi*r^3  so we need to know r

we know surface area, which is 4pi*r^2=3600pi.  so we can solve for r

r=30

so v = 4/3*pi*30^3 = 36000pi

Using f(x) = 8x + 5 and g(x) = 7x - 2, find:g(f(6))
iren2701 [21]

Answer:

369

Step-by-step explanation:

g(f(x)) simply means to put the whole expression of function f(x) into the place of "x" in g(x).

and to find the functional value for a specific x we just need to calculate functional value for f(x) and use that result as input for g(x).

f(6) = 8×6 + 5 = 48 + 5 = 53

and now

g(53) = 7×53 - 2 = 371 - 2 = 369

to check we do the general functional substitution :

g(f(x)) = 7×(8x+5) - 2 = 56x + 35 - 2 = 56x + 33

g(f(6)) = 56×6 + 33 = 336 + 33 = 369

correct

What is the slope of this graph?
larisa [96]
Since the slope is falling, instead of rising, it would be negative. 

Now, on the line, I plotted (0, 2) and (-2, 10).

You would now plug this into the rise/run formula. 
The formula is \frac{y2 - y1}{x2 - x1}

The equation would become, 
\frac{10 - 2}{-2 - 0} = \frac{8}{-2} = -4

I believe the answer would be -4. 

I hope this helps!
