For the function f defined below, what is the value of f(-1)? fx=x+3<br> -----<br> 2
Pepsi [2]

Answer:

6) C 1

7) A 3 (im not sure for this one because it's blurry)

8) C 1

Step-by-step explanation:

6) Replace the f(x) for -1 since we are told f(x) = -1. We then need to use the inverse operation to get x by itself.

- 1 =  \frac{x - 3}{ 2}

Since the opposite of division (which is indicated by the fraction line) is multiplication, we need to multiply the number on the left (-1) times 2.

- 2 = x - 3

For this step, the opposite of subtraction is addition so in this step, we must add 3 to -2.

1 = x

7) Can't explain cause I'm not sure if I'm right

8) To find out the slope of two coordinates we must use the following to determine it.

<h3>(IN THE PICTURE ATTACHED)</h3>

In this case, the y with the little two will be 4 and the y with the little one is 1. 4-1 is 3 and that's the y cooridnate sorted

For the x coordinate, the x with the little two is 1 and the x with the little one is -2. Thus, we must solve 1-(-2) which also equals 3.

<h3>Since the final coordinates are 3/3 and it simplifies, the final answer is 1.</h3>

b. you can multiply 2/3 by 3 to make 6/9

so the LCD is 9

If the interest of sum of money is 6 yrs in 3/8 of the principal . what is the rate of interest?​
REY [17]

Answer :

R = 6.25%

Solution,

Let P is the principal. It means interest will be :

I=3/8 P

The formula for the interest is given by :

I=\dfrac{PRT}{100}\\\\\dfrac{3}{8}P=\dfrac{PR\times 6}{100}\\\\\dfrac{3}{8}=\dfrac{6R}{100}\\\\R=\dfrac{300}{8\times 6}\\\\=6.25\%

Hence, the rate of interest is 6.25%.
