Here, Let the number of weeks = x
Then, Equation would be: 850x - 300x - 7500 = 0
550x = 7500
x = 7500 / 550
x = 13.63
Minimum week can't be in decimal, so we have to pick for nearest larger value which is 14.
In short, Your Answer would be: 14 Weeks
Hope this helps!
Answer:
She is incorrect
Step-by-step explanation:
Step 1: substitute
135 into x in both equations
Step 2: Solve the equations. Once you do this you will get y = 5375 for the first one and y = 4720 for the second one, therefore she is incorrect
Answer:
Real zeroes states that where a graph crosses or touches the x-axis or we can say that
a real zeroes of a function is a real number that makes the value of the function equal to zero.
Given:
Let f(x) =
then, by the definition of real zeroes we have;
f(x) = 0 to find x;
=0
Add 7 to both sides of an equation we get;
=0+7
Simplify:
=7
or
Add 12 to both sides of an equation;
Simplify:
x=
therefore, the real zeroes of a given function is;
Answer:
You would have to find the surface area
Step-by-step explanation:
If you had to find something to FILL the room then you would need volume, however, you are working with walls which can be viewed as 2 dimensional, whilst volume is 3 dimensional.
So what you would do is find the surface area of the walls and the ceiling, and then exclude the floor.
If you are given the total surface area, then you need to find the surface area of the floor and subtract it by the total surface area and that will give you how much paint is needed.
Answer:
-9 tells us how far it fell to the floor
Step-by-step explanation:
her hand is 1 meter above the ground, the drain is 10 meters deep.
-9 tells us the distance between 1 meter and the bottom of the drain
