Answer:
B) 5x+15y=30
5x-5y=10
Step-by-step explanation:
First, we solve the top equations by addition. Multiply the first one by -4.
-4x-12y=-24
4x-8y=4
This equals -20y=-20, so y=1. Now we put that back into either equation and find that x=3. So the solution set is (3,1)
Plugging those into each of the possible choices, we find that the answer is
B) 5x+15y=30. 5(3)+15(1)=30 15+15=30. 30=30 CHECK
5x-5y=10 5(3)-5(1)=10. 15-5=10. 10=10. CHECK
The Pythagorean Theorem is geometry among the three sides of a right triangle . <span>It states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. </span>
Answer:
Here's what I got. First of all, did you meant y=mx+b+mx+mxy+mx=b, because that's undefined, or did you meant y=mx+b+mx+mx, which is b=−3mx+y.
