5y - 20 < 0...add 20 to both sides
5y < 20...divide both sides by 5
y < 20/5
y < 4 (this states that y is less then 4)
Therefore, the greatest integer that y could be is 3 (because integers cannot be fractions, they have to be whole numbers)
Step-by-step explanation:
<u>Given </u><u>:</u><u>-</u><u> </u>
- Ali and mo share a sum of money in the ratio ali : mo = 9 : 7 .
- Ali receives 600 more than mo .
And we need to find out how much each receives .Let us take that
- Mo received x .
- Ali will get x + 600.
<u>According</u><u> to</u><u> the</u><u> Question</u><u> </u><u>:</u><u>-</u><u> </u>
<u>Therefore</u><u> </u><u>:</u><u>-</u><u> </u>
- Ali = x+600 = 2700
- Mo = x = 2100
Answer:
The domain of the function is 0 less-than-or-equal-to x less-than infinity ⇒ 3rd answer
Step-by-step explanation:
The domain of the function f(x) = y is all the values of x which make the function defined
∵ 
- There is no square root for negative number, that means x
must be non-negative number
∵ The non negative numbers start from zero till infinity
∴ 0 ≤ x < ∞
∴ x must be greater than or equal zero and less than infinity
- Values of x are the domain of the function
∴ The domain of the function is 0 ≤ x < ∞
The domain of the function is 0 less-than-or-equal-to x less-than infinity
This is the concept of algebra, to get the values of the unknown we proceed as follows:
Length=(2w-30) cm
width=w
Area=length×width
=w(2w-30)=5400
=2w^2-30w=5400
hence
2w^2-30w-5400=0
solving the quadratic we get:
w^2-15w-2700=0
thus
(w+45)(w-60)=0
hence
w=-45 or w=60
since there is no negative dimension we shall take w=60
thus the value of w=60
