Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = 3x + 1

f(-2/3) is x = -2/3

<u>Step 2: Evaluate</u>

Substitute: f(-2/3) = 3(-2/3) + 1
Multiply: f(-2/3) = -2 + 1
Add: f(-2/3) = -1

Step2247 [10]

Answer:

1) 6x = 21

2) x + y - 3

3) x/z = y

4) 2-x = p

Step-by-step explanation:

1. The product of a number x and 6 is 21

A product is a multiplication. A product of a and b is a * b.

We then have a product of x and 6, that x * 6, which we write usually in the format 6x.

is 21: that means it's equal to 21....

so 6x = 21.

2. The sum of the quantity x- 3 and y

The sum is an addition. The sum of a and b is a + b.

In this case, the first part is x - 3, the second part is y

So, x - 3 + y, which we usually rewrite as x + y - 3

3. The quotient of x and z is y

A quotient is a division.

So, quotient of x and z is x/z.

x/z = y

4. The difference of 2 and x is p.

A difference is a subtraction.

Difference of 2 and x is 2 - x

2 - x = p
