Answer:

B. The function f(x) has an inverse because it passes the horizontal line test.

Step-by-step explanation:

The given function is the graph of  f(x)=(\frac{5}{4})^x+1.

This function will have an inverse <em>if and only if its graph passes the horizontal line test.</em>

That is, if a horizontal line is drawn across the graph, it will intersect the graph at only one point.


Since the graph of the given function passes the horizontal line test, it has an inverse.

See graph in attachment.


The correct answer is B.

Solve:<br> 3/4 (5 f - 3) = 3/8<br> F=?
VMariaS [17]

Answer:

f= 0.7

Step-by-step explanation:

Multiply by reciprocal on both sides: 4/3 * 3/4(5f-3) = 3/8 * 4/3 f

Then, you are left with: 5f-3 = 1/2

Then you subtract by three on both sides to get: 5f=3.5

Finally, divide by 5 on both sides to get: f=.07

From the yearbook receipts the students council deposited apart of the $1200 in a saving account receiving 9% interest per annum
Naddika [18.5K]
There was $800 deposited at 9% interest and $400 deposited at 4% interest.

The formula for simple interest is I = prt.  Using our information we have:

88 = x(0.09)(1) + (1200-x)(0.04)(1)
88 = 0.09x + 48 - 0.04x
88 = 0.05x + 48

Subtract 48 from both sides:
88 - 48 = 0.05x + 48 - 48
40 = 0.05x

Divide both sides by 0.05:
40/0.05 = 0.05x/0.05
x = 800
1200 - x = 400
