y = 2x + 1
What is the solution to the system of equations?
(8, 17) (−8, 17) (−8, −17) (8, −17)
x
Hi Brainiac
y=3x-7
y=2x+1
We need to solve y=3x-7 for y
Now let's start by substitute 3x-7 for y in y=2x+1
y=2x+1
3x-7=2x=1
Now add -2x
3x-7-2x=2x+1-2x
x-7=1
Add 7
x-7+7=1+7
x=8
Our last step is to substitute 8 for x in y=3x-7
y=3x-7
y=(3)(8)-7
y= 24-7
y= 17
Answer : A
I hope that's help:)
Answer: The answer is A
I took the test and got it right.
y = 3x + 1
Which description best describes the solution to the system of equations?
Line y = −x + 2 intersects line y = 3x + 1.
Lines y = −x + 2 and y = 3x + 1 intersect the x-axis.
Lines y = −x + 2 and y = 3x + 1 intersect the y-axis.
Line y = −x + 2 intersects the origin.
Answer:
The correct option is A. Line y = −x + 2 intersects line y = 3x + 1.
Step-by-step explanation:
The first equation is given to be :
y = -x + 2
x 0 2
y 2 0
The second equation is :
y = 3x + 1
x 0 -1/3
y 1 0
Now, The graphs of both the equation are attached below :
So, By seeing the graph, We can observe :
But the description that best describes the solution to the system of equations is : Line y = −x + 2 intersects line y = 3x + 1.
Hence, The correct option is A. Line y = −x + 2 intersects line y = 3x + 1.
