To factorise it start with putting the xs in brackets.
(x )(x )
Then you must find 2 numbers which multiply to +81 and sum to -18.
81 is the product of 9×9 or -9×-9.
9+9=+18
-9+-9=-18
So they two numbers must be -9.
So factorised it is (x-9)(x-9) or (x-9)^2
Answer:
Step-by-step explanation:
3 rows of 21 sneakers.
If you add 21+21 it equals 42, which is two rows. If you add that last row, 42+21, you end up with 63.
Answer:
I hope this helps
Ex: vertical translation |x+5|-2 the graph will shift down 2 units. Or the same as (x+5)+2 in this case the graph will shift up 2 units.
Horizontal translation |x+5|-2 the graph will shift to the left 5 units. Or same as (x-5)-2 in this case the graph will shift over to the right 5 units.
Step-by-step explanation:
Vertical translation is when a graph is being shifted up or down.
Horizontal translation is when a graph is being shifted over left or right.
There is a 1 out of 12, you could have a white shirt and blue pants and on and on with them all
Plug in the first equation into the he second equation
3x-(2x+7)=-9
3x-2x-7=-9
x-7=-9
x=-2
plug in x=-2 into the first equation
y=2(-2)+7
y=-4+7
y=3
answer: (-2,3)
