How are the rules for dividing two negative fractions related to the rules for multiplying
two negative fractions? Will the answer be positive or negative? Explain.
Answers
The relation between multiplying and dividing two negative fractions is needed.
When multiplying and dividing two negative fractions the answer will be always positive.
Let [tex]-\dfrac{a}{b}[/tex] be one fraction
and [tex]-\dfrac{c}{d}[/tex] be another fraction
Let us multiply them
[tex]-\dfrac{a}{b}\times -\dfrac{c}{d}=+\dfrac{ac}{bd}[/tex]
Let us divide them
[tex]\dfrac{-\dfrac{a}{b}}{-\dfrac{c}{d}}[/tex]
This can also be written as
[tex]-\dfrac{a}{b}\times -\dfrac{d}{c}=+\dfrac{ad}{bc}[/tex]
Since, multiplication and division are the inverse of each other the negative signs cancel each other and the sign is positive.
Hence, when multiplying and dividing two negative fractions the answer will be always positive.

Caffenine takes a certain amount of time to leave your system if you drink 3 cups of coffe in the morning the function that represents the amount of caffeine remaining in your body after drinking the coffe is given by g(t)=130(.8346)^t where t is the timein hours. how much caffeine remains in your body after 1 day. how much caffeine remains in your body after 2 days
Answers
Answer:
In 1 day, 1.70
In two days 0.022
Note; Unit was not given in the question, I would have included it
Step-by-step explanation:
Here, we are to calculate the amount of caffeine remaining in the body.
To calculate this, we simply substitute for the number of hours t in the equation.
In one day , we have 24 hours
So our substitution will be t = 24
Hence; for a day;
g(24) = 130(0.8346)^24 = 1.70
For two days, we have t = 48 hours
Thus; g(48) = 130(0.8346)^48 = 0.022
A retiree has $200,000 to invest and needs to make $13,000 with her investments. If she can invest in government bonds at 6% or investment grade bonds at 8%, how much should she invest in each?
Answers
Answer:
She should invest 150,000 in government bonds and 50,000 in investment grade bonds
Step-by-step explanation:
Let the amount invested in government bonds be $y while the amount invested in investment bond be $x
Since total is $200,000
Then:
x + y = 200,000 ••••••(i)
Since 13,000 is what is expected to be earned, then this is like the interest.
thus;
6% of x + 8% of y = 13,000
6x/100 + 8y/100 = 13,000
Multiply through by 100
6x + 8y = 1300000 •••••••(ii)
From i, x = 200,000 - y
insert this into ii
6(200,000-y) + 8y = 1300000
1200000-6y + 8y = 1300000
2y = 1300000-1200000
2y = 100,000
y = 100,000/2
y = 50,000
but x + y = 200,000
thus, x = 200,000 - 50,000
x = 150,000
3(x+-10)=5(2x+8) Honestly I hate math lol.
Answers
x = -10
Use the distributive property to multiply 3 by x−10
3x−30=5(2x+8)
Use the distributive property to multiply 5 by 2x+8
3x−30=10x+40
Subtract 10x from both sides
3x−30−10x=40
Combine 3x and −10x to get −7x.
−7x−30=40
Add 30 to both sides
−7x=40+30
Add 40 and 30 to get 70
−7x=70
Divide both sides by −7
x= 70/-7
Divide 70 by −7 to get −10
Hope this helps :)

You deposited $100 in a savings account 3 years ago. The simple interest rate is 2.3%. How
much money is in the account after 3 years?
Answers
Answer:
Final Balance = 106.90$
Step-by-step explanation:
Using the simple interest formula I = prt.
The current balance after accumulated interest is B = I + p.
Given a principle of $100, time of 3 years, and interest rate of 2.3%.
I = (100$)(3y)(2.3%) = (100)(3)(2.3%) = (300)(2.3%) = (300)(0.023) = 6.90$
B (final balance) = 6.90$ + 100$ = 106.90$

what is it .?
Answers
Answer:
- 33
Step-by-step explanation:
Step 1:
2x - 3x = 33 Equation
Step 2:
- x = 33 Subtract
Answer:
x = - 33
Hope This Helps :)
The solution to the equation 2x - 3x = 33 is x = -33.
To solve the equation 2x - 3x = 33, we need to combine like terms on the left side of the equation and then solve for x.
Combine like terms:
2x - 3x = -x
Rewrite the equation with the combined terms:
-x = 33
To isolate x, we need to multiply both sides of the equation by -1:
(-1)(-x) = (-1)(33)
This simplifies to:
x = -33
Therefore, the solution to the equation 2x - 3x = 33 is x = -33.

X-intercept:
Need to know NOW
Answers
Answer:
y = 12
x = 10/3
Step-by-step explanation:
y = -3.6x + 12
From this equation, which is in slope intercept form (y = mx+b), we already know that b represents the y-intercept, so that means the y-intercept is 12.
To find the x-intercept, we need to make y equal 0 to find x. So:
0 = -3.6x + 12
-3.6x = -12
x = 3.33333 --> 3 1/3
x = 10/3
x-intercept: 10/3
y-intercept: 12
Steps:
Finding x
y=-3.6x+12
0= -3.6x+12
3.6x=12
x=10/3
Finding y
y=-3.6x+12
y=-3.6(0)+12
y=12
