When solving a system by graphing you need to see where the lines intersect.
Below is a picture of these lines graphed. The green line is y = x +4 and the blue line is y = 4x - 1
The red dot represents the intersection is about (1, 5)
The original point is: (1.667, 5.667)
Hope this helped!
in this problem what you are really looking for is which of these sets is a pathagorean triple. That means it will solve the pathagorean theorem. (a sqaured + b squared = c squared) c is always going to be the largest number or the hypotenuse. if you plug all the number sets into the theorem, only one works and that is 7, 24, 25 which is your answer.
Answer:
Yes
Step-by-step explanation:
To find the answer, you just have to plug the (x,y) values into the equation to see if it is true.
3(1) > 5(-6) -12
3 > -30 -12
3 > -42
Since 3 > -42 the ordered pair is a solution to the inequality
