Answer:
10 weeks
Step-by-step explanation:
lets build a equation for this
500-30(x)........where x is the number of weeks
500-30(10)= $200 left
so she can maximum withdraw money for about 10 weeks
Answer:
Step-by-step explanation:
Let the number be x;
The product of 4 and the number will be;
The the square of the number is given as;
Taking the difference of both expressions above;
Factor out the common term:
Hence the difference between the product of 4 and a number and the square of the number is
Answer:
x = 5
Step-by-step explanation:
x^2/(x + 5) = 25/(x+5) Subtract the right side from both sides.
x^2/(x + 5) - 25/(x + 5) = 0
x^2 - 25
======= = 0
x + 5
(x + 5)(x - 5)
============= = 0
(x + 5)
Cancel x + 5 in the numerator and denominator.
x - 5 = 0
x = + 5
Does it check?
x^2/(x + 5) = 25/(x + 5)
x = 5
5^2/(10) = 25/10
25/10 = 25/10 Yes it checks.
Answer:
it equals 79
Step-by-step explanation:
so basically for this problem you're just going to plug in the point (3,-3) into every equation, keeping in mind that the 3 is the x value and that the -3 is the y value. once you plug it in you can just use order of operations (pemdas) to solve.
the equations that do work with the point (3,-3) are (2x+4y=-6)
(2x-3y=15)
(8x+3y=15)
(7x-2y=-24)
Step-by-step explanation:
so to work one of these problems you take (2x+4y=-6) and plug in your variables.
2(3)+4(-3)=-6
then you're going to multiply
6-12=-6
the subtract the negative twelve from the 6
-6=-6
so we get a true statement. if you do this and the two numbers don't match then the equation does not work with your point. I hope this helps!
