Answer:
yes it is
Step-by-step explanation:

elimination means to get rid of one variable by altering the coefficients of variable (by multiplying and diving by some constant number)
in this case, if you just add the two equation, y gets cancelled you get 5x=20 or x=4
put it in any equation to get y (this works because both lines pass through the same point, so they must satisfy that point) to get y=2
Answer:
False
Step-by-step explanation:
If it is a right triangle, the Pythagorean theorem will apply
a^2 + b^2 = c^2
4^2 + 5.05^2 = 6.6^2
16 +25.5025 =43.56
41.5025=43.56
This is not true so it is not a right triangle
Round to the nearest integer
4^2 + 5^2 = 7^2
16+25 = 49
41 =49
This is not true
A=P(1+r/n)^nt is the formula for finding compound interest
