Answer:
D) -4x+14
Step-by-step explanation:
We are given with the expression
3 - (4x - 5) + 6
Here we are going to open the bracket at first step
as we have a negative sign in front of bracket the signs of the terms inside brackets will be reversed
3-4x+5+6
now we bring the like terms together
3+5+6 - 4x
Here 3, 5, 6 all are constant and hence like
14-4x
or
3 - (4x - 5) + 6= -4x+14
Hence our answer is -4x+14
5(x²+x-2x-2)
5(x²-x-2)
5x²-5x-10
you can also simplify to x²-x-2.
Answer: x=-2 y=2
Step-by-step explanation:
I decided that isolating the y value of the second equation is the best way to start solving.
I divide 3 from both sides to get y= (4-x)/3. With this, I can substitute into the first equation. 4x+3(4-x)/3)=-2.
The multiplying the 3 by the denominator three cancels each other out to make:
4x+4-x=-2.
We subtract 4 on both sides and then subtract x from 4x.
We end up with 3x=-6. Then, we divide both sides by 3.
x=-2.
Now we substitute this into the second equation to solve.
3y=4-(-2)
This becomes 3y=4+2 which is 3y=6
We divide both sides by 3 to get y=2
We end up with x=-2 and y=2.
I hope you learned something :)

Answer:
option 2
Step-by-step explanation:
consider the coordinates A (- 3, 4 ) and A' (- 1, 
)
since the dilatation is centred at the origin, then corresponding coordinates are multiples/ divisors of each other, then image to original gives scale factor.
scale factor = 
= 
= 
and 
=
similarly B (1, - 2 ) and B' (, - 
)
= and 
=
