5x+y=2
4x+y=4
5x+y=2
-1( 4x+y=2)
5x+y=2
-4x-y=2
your y'all cancel out so you r left with
x=-2
then you plug the x in to one of the equations
5(-2)+y=2
-10+y=2
then add 10 to both sides
y=12
Answer: x = -2 y = 12
there's the work and all its simple you just have to figure out how to get rid of y or x ( which ever is easier) and you can figure it out after that
Greetings!
What is parallel line and perpendicular line? Give real life example with neat figure.
- Parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel.
- Perpendicular means "at right angles". A line meeting another at a right angle, or 90° is said to be perpendicular to it.
Answer: 181.25
Step-by-step explanation:
So 4 to 5 is a ratio. Now there is 145 girls, so you figure out 4 multiplied by what is equal to 145. You get 36.25, so you multiply the number 5 by the same number to get your answer. 36.25*5=181.25
Answer:
C. a reflection in the y-axis
Step-by-step explanation:
The mapping statement for the transformation of the vertices of the triangle ABC is given as following:
A(0,2)→A'(0,2)
B(2,9)→B'(-2,9)
C(4,2)→C'(-4,2)
To find the correct transformation for the given statement.
Solution:
From the given statements, the general transformation statement for the the vertices of the triangle can be given as:

The above transformation shows a reflection in the y-axis as the transformation in y-axis changes the sign of the x-coordinate of the point.
