Step-by-step explanation:
<u>Step 1: Define</u>
y = 2x + 12
x = 3
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: y = 2(3) + 12
- Multiply: y = 6 + 12
- Add: y = 18
Answer:
If the two linear equations have the same slope, the equations represent the same line. Since a line intersects with itself everywhere, there will be an infinite number of solutions.
Function 2 has a greater y-intercept
<h3>Graphs</h3>
Graphs can be used to represent functions, equations, tables and relations
<h3>Equations</h3>
The equation of function 1 is given as:
To calculate the y-intercept, we set t to 0.
So, we have:
For the table of function 2, the y-intercept is 5.25
By comparison:
5.25 is greater than 5
Hence, function 2 has a greater y-intercept

Answer:
let the angles be 7x , 13x , 16x
7x + 13x + 16x = 180 ( sum of angles in a triangle is 180 degree)
36x = 180
x = 180 / 36
x = 5
therefore the angles are:
7 X 5 = 35 degree
13 X 5 = 65 degree
16 x 5 = 80 degree

Answer:
6
Step-by-step explanation:
4 x 3 = 12
8 x 3 = 24
12 / 4 = 3
24 / 4 = 6
x must be 6
