Answer:
The last one
Step-by-step explanation:
Answer: the system has one solution which is x = 0, y = 5.
Explanation:
The pair of equations given constitute a system of two equations with two variables.
A system of linear equations may have a single solution, no solution (parallel lines) or infinite solutions (same line).
To find the solution or determine whether the system has one or infinite solutions, you may manipulate the equations.
This is the original systeym as given:
Multiply the first equation by 3 and the second equation by 2:
Subtract the first equation from the second:
Substitute x = 0 in any of the original equations to find y:
- 2y = 0 + 10
- 2y = 10
- y = 10 / 2
- y = 5
Hence, the system has one solution which is x = 0, y = 5.
The measure of angle 1 is 210 degrees.
You'll have to draw an auxiliary line in between the two parallel lines.
Then, you'll have to find out the angle measures next to 100 and next to 50. Since a line is 180°, then the angle measures next to 100 and 50 are 80 and 130 respectively.
Then, since you have an auxiliary line, you can use the rule of alternate interior angles of parallel lines being equal.
Then from there just add up 80 and 130 to get you 210.
Answer:
1.- If a number can be written or can be converted to p/q form, where p and q are integers and q is a non-zero number, then it is said to be rational and if it cannot be written in this form, then it is irrational.
2.- The square root of a number is that number which when multiplied by itself two times gives us that number.
Example:
Let us use the square root of 64.
√64 = x , so that (x)(x) = 64
We know that, (8)(8) = 64
∴ √64 = 8
The cube root of a number is that number which when multiplied by itself three times gives us that number.
Example:
Let us use the square root of 64
∛64 = x , so that (x)(x)(x) = 64 ,
We know that, 4 x 4 x 4 = 64
∴ ∛64 = 4
