Since you did not include the choices to select the correct table, I will 1) explain you how to creat a table, and 2) create a table w hich which you migh compare with your choices:
1) How to make a table
For the function y = x + 4, the variable x is the input and the variable y is the output.
A table consists of a sequence of pairs x, y.
You choose the x-values and calculate th y-values using the function.
For expample if you choose x = 3 as your input, then the output is given by the function y = x + 4, so you subsititute x = 3 and obtain y = 3 + 4 = 7.
And the table is represented as in the example below.
What you have to do is checking if all the values of the table given satisfy the equation y = x + 4.
2) Table (example):

y = x + 4

The answer to the problem is 36.
Answer:
Step-by-step explanation:
The first step to do is make a single triangle from the problem. That triangle can be BDH. We do still need the line BE, although that can wait.
Now find the last angle of the triangle. The sum of angles of a triangle always equal 180, so we can easuly find the missing angle.
So the missing angle is 109°. Now we can find the value of x.
We can use that angle because it sits right next to x on the same line. A line is 180° at any node as long as the line continues straight, so we simply subtract the angle we just found to find x.
Now we know x is 71
Answer:
0.88 s
Step-by-step explanation:
Let x(t) be the volume of nitric acid measured in liters after t minute. Therefore the rate of change in the volume of nitric acid (dx / dt) is:
dx / dt = rate of input of nitric acid - rate of output of nitric acid
rate of input of nitric acid = 6 L/min * 20% nitric acid / 100% solution = 1.2 L/min
rate of output of nitric acid = 8 L/min * x L / 200 L = 0.04x L/min
The percentage of nitric acid in the tank reach 10% at 0.88 s
