Answer:
multiply by 2
Step-by-step explanation:
5x2=10
10x2=20
There would be a hole when x = -4.
If you factor both the top and the bottom, you will see that the factor (x + 4) is in both the numerator and denominator. Therefore, the would be a hole when x = -4 because that would also make the denominator 0.
Answer:
The first answer is correct.
(x + 1)^2 + (y - 2)^2 = 1
A circle with the midpoint M(Mx, My) and the radius r can be written as
(x - Mx)^2 + (y - My)^2 = r^2

Answer:
₹14000
Step-by-step explanation:
Let c represent the cost price, and m represent the marked price.
c × (1 +40%) = m
m × (1 -15%) - c = ₹1900
Using the first expression for m, the second equation becomes ...
1.40c×0.85 -c = ₹1900
0.19c = ₹1900
c = ₹1900/0.19 = ₹10000
Then the marked price was ...
m = 1.40c = 1.40×₹10000 = ₹14000
The marked price was ₹14000.
_____
The selling price was ₹11900.
30:6 is an equivalent ratio. Anymore and you would have a decimal.
