You have two exponential functions. One function has the formula g(x) = 3 x . The other function has the formula h(x) = 2-x . Wh
Vlada [557]

Answer:

see graph


Step-by-step explanation:

g(x) = 3^ x .

h(x) = 2^-x

We want to subtract them

f(x) = 3^x - 2^(-x)

I will rewrite without the negative exponent

f(x) = 3^x - (1/2)^(x)

Lets pick a couple of points

f(0)  = 3^0 - (1/2) ^ 0 = 1-1 = 0

As x gets large 3^x gets large and 1/2^x gets close to 0, so it will get large

As x goes to negative infinity, 3^x goes to zero and 1/2^ gets large  so we get - infinitity

Graph the function -2x+5y=10
loris [4]
An equation of the form ax+by+c=0, where x, y are variable, and a, b, c are numbers, is called a "linear equation"

the reason we call it linear, is that all solutions (x, y) to this equation, when plotted in the x-y axis, form a line.

To draw this line, 2 points are enough, that is 2 solutions (x, y) of the equation.

-------------------------------------------------------------------------------------------------

-2x+5y-10=0 is a linear equation (a=-2, b=5, c=-10)


to find 2 solutions, we set x or y any value we want, and solve for the other

for example: 

let x=0, 

then

-2x+5y-10=0 becomes 5y-10=0, so y=2

this gives us the solution (0, 2)

another example; set y=0

then -2x+5y-10=0 becomes -2x-10=0; -2x=10 so x=-5

thus another solution is (-5, 0)



Draw these 2 points, and join them with a line, as shown in the figure.

Can someone please help me on this question? This question has 2 answer choices. Thank you.

Hello!

To solve this you have to find the ratio between the two cylinders

Cylinder 1 height is 30
Cylinder 2 height is 20

this is a 30:20 ratio

This can be reduced to a 3:2 ratio

Now you look for one that are also equal to 3:2

3 * 7 = 21
2 * 7 = 14

The answers are 3:2 and 21:14

Hope this helps!
