Step-by-step explanation:

I. 10x + 12y = 23

II. 5x + 4y = 10

I - 2*II

4y = 3 --> y = 3/4 = 0.75

5x + 4*3/4 = 10

5x + 3 = 10

5x = 7

x = 7/5 = 1.40

One granola bar cost 1.40 and one bottle of water cost 0.75

Answer:

2.15

Step-by-step explanation:

Let g= cost of granola bars

b = cost of bottles of water


10g+12b =23

5g +4b = 10

I will solve this system by elimination

Multiply the second equation by -2


-2(5g +4b) = -2*10

-10g -8b = -20

Now we add this equation to the first equation to eliminate  g

-10g -8b = -20

10g+12b =23

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

   4b = 3

b = 3/4

A bottle of water = $.75

Now we need to find g

5g+4b =10

5g +4(.75) = 10

5g +3 = 10

Subtract 3 from each side

5g +3-3 = 10-3

5g =7

Divide by 5

5g/5=7/5

g = 7/5

g = 1 2/5

g =1.40


We want the cost of one bottle of water and 1 granola bar

1g + 1b

1.4+.75

If f(3) = 3^x and g(x) = 7^x then the graph of g(x) will be — the graph of f(x) when x<0.
Allushta [10]

Using the given exponential functions, it is found that the graph of g(x) will be less than than the graph of f(x) when x < 0.

<h3>What are the exponential functions?</h3>

The given exponential functions, f(x) and g(x), are respectively given by:

  • f(x) = 3^x
  • g(x) = 7^x

When x < 0, one possible value is x = -1, hence evaluating the functions at these values:

f(-1) = 3^{-1} = \frac{1}{3}

g(-1) = 7^{-1} = \frac{1}{7}

\frac{1}{3} > \frac{1}{7}, hence, the graph of g(x) will be less than than the graph of f(x) when x < 0.
