ANSWER
(3,-1)
EXPLANATION
The given system of equations is :
5x+y=14
2x-y=7
For the first equation when x=0,
5(0)+y=14
y=14
The y-intercept is (0,14).
When y=0, 5x+0=14
The x-intercept is (2.8,0).
We plot the intercepts and draw a straight line through them to obtain the graph of 5x+y=14 as shown in the attachment.
We repeat the same process for the second equation 2x-y=7.
The intercepts are (0,-7) and (3.5,0)
The solution to the system is the point of intersection of the two straight lines.
The two straight lines intersected at
(3,-1)
Hence x=2, y=-1
Answer:
(3,-1) A
Step-by-step explanation:
So we just add x-y=4 and x+y=2 to find our first value x. since the y's will cancel out each other out.
So x plus x= 2x and -y+y= cancels out the ys and 4 plus 2= 6. So we make our new equation with the y out. 2x=6 then dived both sides by 2 to get x=3
Then to find y times the first equation by negative 1. then the second by 1. So that changes the first equation to -x+y=-4 and the second to x+y=2 that way we cancel out the <em>x's</em><em> </em>this time. So add them together. -x plus x= cancels them out. y plus y= 2y and then -4 plus 2=-2. So that makes our equation 2y=-2 so dived both sides by 2 and you get
y=-1
Hope this helps!
111+496= 607
1/10 + 1/10 = 2/10
607 + 2/10 = 607 and 2/10
But if youre just doing an approximate answer then...
111 = 110
496 = 500
So it would be 610
You can make 2/10 to 1/5 but that wouldnt be approx.
Your answer should be 610 and 2/10
