Answer:
A=4
B=-2
Step-by-step explanation:
the gradient to B is a negative coz the line is sloping downwards
m (A) = 4
m (B) = - 2
choose any 2 coordinates on line A to use it in the formulae
no need to do so for line B because the y-int and x-int both are clear.
5,850 - 6,150/ 5,850≤x≤6,150
All we really need to see here is what is 2.5% of 6,000, that is 150,
Now, we just add/ subtract that from 6,000 to get our range
Answer: x=7
1 Add
9
9 to both sides.
2
x
=
5
+
2x=5+9
2 Simplify
5+9 to
14
14.
2x=14
3 Divide both sides by
2.
x=
4 Simplify
to
7
7.
x=7
So he has $1.10 in total.
You add 0.75+0.20+0.15 and get 1.10.
