Simplify 7(x-4)-3x+2x:
4x-26=3x-2-x
Subtract x from 3x:
4x-26=2x-2
Move all terms containing x to the left:
2x-26=-2
Move all terms not containing x to the right:
2x=24
Divide by 2 and simplify:
x=12
Answer:
7n - 1
Step-by-step explanation:
notice that the difference between adjacent terms is 7.
so nth term is given by:
nth term = first term + (n-1)×difference (n is any number)
= 6 + (n-1)7
= 6+ 7n -7
= 7n - 1
hope this helps :-))
Answer:
y = - 10
Step-by-step explanation:
2x - 5y + 3 = 6x - 3y + 7
2(4) - 5y + 3 = 6(4) - 3y + 7
8 - 5y + 3 = 24 - 3y + 7
11 - 5y = 31 - 3y
11 - 11 - 5y = 31 - 11 - 3y
- 5y = 20 - 3y
- 5y + 3y = 20 - 3y + 3y
- 2y = 20
- 2y ÷ - 2 = 20 ÷ - 2
y = - 10
It would be the second one because since it’s at 5. You shift from 5 to 8 three units to the right
Answer:
(-2,-3)
Step-by-step explanation:
Since there is a point P including coordinates (-1,5) and it is shown on a horizontal line i.e y =1
Now we have to compute the new coordinates of P
If a point is mirrored along a horizontal line, only vertical distance varies, however the horizontal distance is still the same, i.e. from y axis or x coordinate.
Therefore new x coordinate = -1
As P has 4 distance from the line y =1
Therefore P' will also contains a distance of 4 on the other side of y = 1
i.e. y coordinates could be
= 1 - 4
= -3
hence, the new coordinate is (-2,-3)
