LET x=0 x-2y=4 what is the value of y?
Amanda [17]

Answer:

When x = 0, then y = -2

When y = 0, then x = 4

Step-by-step explanation:

We are given with the following equation;

x - 2y = 4

Now, we have to find the respective values of x and y for each value of x = 0 and y = 0.

Firstly, putting the value of x = 0;

x - 2y = 4

0 - 2y = 4

-2y = 4

y = \frac{4}{-2}  = -2

This means that when x = 0, then y = -2.

Similarly, putting the value of y = 0;

x - 2y = 4

x-(2\times 0)=4

x - 0 = 4

x = 4

This means that when y = 0, then x = 4.

Solve the inequality: 3p - 16 &lt; 20
Alekssandra [29.7K]

Isolate the p. First, add 16 to both sides

3p - 16 (+16) < 20 (+16)

3p < 36

Next, isolate the p. Divide 3 from both sides

3p/3 <36/3

p < 12

p < 12 is your answer

hope this helps
