I think elimination method means, add or subtract two equations in a way that it cancels a term out.
E. G.
Add the two equations,
x = y + 3
y= - 4x - 3
x+y = (y+3) + (-4x-3)
x+y = y - 4x
x=-4x
x=0
To find out Y using elimination method,
Muliply 4 to the first equation, and then subtract the second equation from the first.
4x = 4y +12
y= -4x - 3
4x-y = (4y+12) -(-4x-3)
4x-y = 4y + 4x + 15
-y = 4y + 15
-5y = 15
y = - 3
Hope this helps. Thanks
Answer:
The y-intercept of this line is -8.
Answer:
Range values are:
{-11, 1, 4, 10, 25}
Step-by-step explanation:
Domain values are the possible x values that can be entered into the function, or the inputs. Range values are the y values, or the outputs. By inserting every value in the set into the function, we get the outputs (y values)
-15 + 4 = -11
-3+4 = 1
0 + 4 = 4
6 + 4 = 10
21 + 4 = 25
Remember to put them in order.
1,2, and 3 is the correct answer.
so lets do some rounding!
3,972,463 can be rounded to 4,000,000
4,562,234 can be rounded to 4,500,000
so the answer should be D
hope that helped, have a nice day and vote me for brainliest if it helped!
