To solve this problem you must think in this way.

First we see that function y is greater than 3-x, conclusion is the following

shaded area must be above function. That condition is satisfied by the graph 3 and 4.

Then we write inequality in the slope form y> -x+3.

We see that the coefficient of direction is -1 (negative) which mean that the graph is decreasing. That condition is satisfied by the graph No 4.

The correct answer is graph number 4 ( or D.)

Good luck!!!

We know that y is equal to x-2. We can just substitute x-2 for y since y is equal to it.

10x- 9(x-2)=24

Distribute.

10x- 9x+18= 24

x+18= 24

Subtract 18 on both sides.

x= 6

Now, plug in x.

y= (6)-2

y= 4

We can check this to see if this works:

4= 6-2, 4=4

10(6)- 9(4)= 24

60-36= 24, 24=24

x=6 and y=4

I hope this helps!

A savings account with compounded interest can be modeled by which type of graph

Leona [35]

Answer: The answer is (C) Exponential.

Step-by-step explanation: We are to select out of the given options the type of graph that a savings account with compounded interest be modelled.

We know that compounding gives more interest because we are earning interest on interest, and not just on the principal.

The formula foe compound interest is given by

$C.I.=P(1+\dfrac{r}{100})^n,$ where, 'P' is the principal, r is the rate of interest and 'n' is the number of years.
