Find y when x=14 if y varies inversely as x and y=5 when x=8
Answers
5 = k/8
k = 5 x 8 = 40
Therefore,
y = 40/14 = 2.86

add 2
x+2-2>-6+2
x+0>-4
x>-4
x is more than -4 (pick any number)
isolate x
x-2>-6
+2 +2
x>-4
Thus, your answer.

Keep going until you have only one number left. That's the smallest one,
out of the entire original list.
In the example you gave, the smallest digit in the first place after the decimal point
is the '0', and choice-'C' is the only one that has it. So choice-'C' is the least, and
you don't need to go any farther.

c = 235 + 30w
c = 185 + 35w
The solution to the system is (10, 535).
Which interpretation correctly describes the solution to the system of equations?
a. Larry’s Landscaping will charge more money on the tenth week by charging $535.
b. Joe’s Landscaping will charge more money on the tenth week by charging $535.
c. The cost for lawn maintenance is the same, $535, for both landscaping companies after 10 wk.
d. A customer can have his or her lawn maintained for a maximum of 10 wk. The customer will pay a total of $535.
Answers
535 = 235 + 30(10)
535 = 185 + 35(10)
Then, you would just solve the equations.
535 = 235 + 30(10)
30(10) = 300
300 + 235 = 535
So the first equation is true, and we know for a fact that Larry's Landscaping charges $535 for a spring cleaning and weekly yard maintenance for 10 weeks.
On to the next equation.
535 = 185 + 35(10)
35(10) = 350
185 + 350 = 535
So, the second equation is true also. And we also know for a fact that Joe's Landscaping charges $535 for a spring cleaning and weekly yard maintenance for 10 weeks.
So, now that we know that they will end up charging the same amount of money for a spring cleaning and weekly yard maintenance, the only answer that fits that is C. The cost for lawn maintenance is the same, $535, for both landscaping companies after 10 weeks.
Hope this helps!
