Answer:
x = 399 new subscribers
Step-by-step explanation:
Let 420 = 100%
x = 95%
420*95 = 100x
x = 420*95/100
x = 399 new subscribers
Answer:
The last one
Step-by-step explanation:
Domain is on the x - axis, so it starts and stops on 1 and 6 and all the other symbols mean that x could be 1, 6, or anything in between. Range is on the y - axis, so the highest point is seven and the lowest is one. Y could be 1, 7, or anything in between.
Answer:
1. x>20 2. x≤1 3.x<4 4.x>9 5.x≥-13
3/4 (x+8)=9
3/4x+6=9
-6
3/4x=3
X=4
Check
3/4(4+8)=9
3/4 (12)=9
9=9
Answer: the expression for the width is x + 4
Step-by-step explanation:
The area of the rectangle is expressed as
Area = x² + 13x + 36 square meters.
The length is expressed as
L = x + 9 meters
To determine the expression for the width of the rectangle, we would factorize the expression for the area. Hence
x² + 13x + 36 = 0
We would find two numbers such that their sum or difference is 13x and their product is 36x². The two numbers are 9x and 4x. Therefore,
x² + 9x + 4x + 36 = 0
x(x + 9) + 4(x + 9) = 0
(x + 4)(x + 9)
Therefore, the expression that represents the width of the rectangle is x + 4
