7200 kg = 7.200.000 grams because 1 kg is 1000 grams
Hello,
Yes,
imagine 2 rights triangles having the hypotenus in commun.
Start with the point-slope formula: y-k = m(x-h), where (h,k) is the given point and m is the given slope:
y+3 = (1/2)(x-2)
This equation can be rewritten in other forms if desired.
The coordinates of the reflected point that is reflected across the x-axis to obtain a new point is (1,5).
Answer:
Part 1) The solution of the system of equations is (2,-5)
Part 2) The solution of the system of equations is (2,4)
Step-by-step explanation:
Part 1) Linear combination
we have
-----> equation A
-----> equation B
Multiply equation B by 2 both sides

-----> equation C
Adds equation A and equation C

Find the value of y




The solution of the system of equations is (2,-5)
Part 2) By graph
-----> equation A
-----> equation B
we know that
The solution of the system of equations is the intersection point both graphs
Using a graphing tool
The intersection point is (2,4)
therefore
The solution of the system of equations is the point (2,4)
see the attached figure
