2x+3y= -17
5x+2y= -4
You must cancel either the x or y out to solve so i'm going to cancel the x.
-5(2x+3y= -17)
2(5x+2y= -4)
This simplifies to:
-15x -15y=85
15x+4y= -8
The -15x and 15x cancel out leaving you:
-15y=85
4y= -8
You add them top numbers by the bottom and get:
-11y=77
Then divide by -11 to get y by its self.
y= -7
Now that you know what y is just plug it in to either original problem. I will use the second one.
5x + 2(-7) = -4
5x -14 = -4
5x = 10
x = 2
So the answer is (2,-7) or x=2 and y=-7
Given Function: <span>x + 3y=1
Solve into y=mx+b form
subtract x from both sides
3y=1-x
Divide both sides by 3
y= 1/3 - x/3
The graph is neither vertical or horizontal. It has a decreasing slope </span>
2.54 cm/ 1 in = 60 in/ 1. Then you would multiply 2.54 by 60 and get 152.4 cm
Answer:
22.9 ft
Step-by-step explanation:
the height of the wall that reached by the ladder = √ (25²-10²)
=√(625-100)
=√525
= 22.9 ft
No solution
Ex:
Simply 2.40+1.8 to 4.2
