Where do y=10x+20 and y=5x+50 intercept
1 answer:
Point of intersection is: (6,80)
Step-by-step explanation:
In order to find the point of intersection for two lines we solve the equations.
Given equations are:
Putting y = 5x+50 in equation 1
Putting x=6 in equation 1
Hence,
Point of intersection is: (6,80)

Answer:
The correct options are 1, 3 and 4.
Step-by-step explanation:
We need to find the expressions whose simplified form is a rational number.
Rational number: If a number is defined in the form of p/q where p and q are integers and q≠0, then it is called a rational number.
For example: 0,2, 4.3 etc.
Irrational number: If a number can not defined in the form of p/q, where p and q are integers and q≠0, then it is called an irrational number.
First expression is
12 is a rational number.
Second expression is
is an irrational number.
Third expression is
21 is a rational number.
Fourth expression is
5 is a rational number.
Therefore, the correct options are 1, 3 and 4.
