First distribute: 4x-12=5x+5. subtract 4x on both sides: -12=x+5. Now subtract 5 from both sides. x=-17.
Answer:
one eraser would cost £4.25
Step-by-step explanation:
as 9 erasers cost £38.25
divide 38.25 by 9 to find the total cost of one eraser
then the answer should be £4.25
therefore one eraser would cost £4.25
I would have to say -0.5 then positive 0.25 because the rule seems to be divide by -2.

Answer:
<h2>Option D is the right answer.</h2>
Step-by-step explanation:
We need to find the option for which the value of the function will be increasing, with the increasing variable.
Vertical line means the value of the x is constant, for any y. Hence, it is not the answer.
Horizontal line represents constant functions. Hence option B can not be the answer.
The data having a positive slope represents a <u>increasing function with the increasing variable</u>. Vice-versa for the data having a negative slope.
That is why option D will be the answer.
