if the sum of two expressions is 3x+5 and one expression is 5x-7 what is the other expression
Answers
Answer:
-2x + 12
Step-by-step explanation:
If we call our other expression y, we can set up an equation tying together 3x + 5, y, and 5x - 7:
[tex](5x-7)+y=3x+5[/tex]
Solving for y by subtracting 5x - 7 from both sides will get us the expression we're looking for:
[tex]y=3x+5-(5x-7)\\y=3x+5-5x+7\\y=-2x+12[/tex]
So the other expression in the sum is -2x + 12.
A student received a coupon for 20% off the total purchase price at a clothing store. Let y be the
original price of the purchase. Use the expression below for the new price of the purchase. Write
an equivalent expression by combining like terms.
y-0.2y
Answers
Answer: 0.8y
Step-by-step explanation:
Original price of purchase = y
Since the received a coupon for 20% off the total purchase price at a clothing store, the expression for the new price will be:
= y - (20% × y)
= y - (0.2 × y)
= y - 0.2y
= 0.8y
The equivalent expression is 0.8y.

Identify the requirements for a discrete probability distribution. Choose the correct answer below. A. There must be a fixed number of independent trials. There must be two mutually exclusive outcomes for each trial with a constant probability of success. B. The sum of the probabilities must equal one. Each probability must be between zero and one inclusive. C. Each probability must be between zero and one inclusive. D. The sum of the probabilities must equal one.
Answers
Answer:
B. The sum of the probabilities must equal one. Each probability must be between zero and one inclusive
Step-by-step explanation:
The discrete probability distribution is a distribution in which the random variable would be considered as countable i.e. non-negative digits also it would be presented in table form
So according to the given situation, the option b is correct as their sum would be equivalent to zero also each probability should be lies between zero and one inclusive

Your parents car initially costs $18,000 and it depreciates at a rate of 12% a year. How much will the car be worth after 5 years.
Using this equation, when your parents give you the car when the value drops below $2,000, in what year of depreciation will you become the owner?
Answers
Answer:
Step-by-step explanation:
value after five years = $18,000×(1-0.12)⁵ = 18,000×0.88⁵ = $9,499.17

The value drops below $2,000 in the 17th year.
Calculus I: Find the smaller and larger x value.
Answers
Answers:
Smaller x value = -3Larger x value = -1===============================================================
Explanation:
Apply the derivative (see attached image for the steps)
You should get [tex]\frac{dy}{dx} = -\frac{1}{(x+2)^{2}}\\\\[/tex]
The line y = x is really y = 1x+0. We see that it's in the form y = mx+b with m = 1 as the slope. The negative reciprocal of this is m = -1, which is the perpendicular slope. As a rule, any two perpendicular lines always have their slopes multiply to -1 as long as neither line is vertical or horizontal.
So we want the derivative we just found to be set equal to -1, that way we have the x value lead to this derivative slope value.
We want dy/dx = -1
In short, the equation we need to solve is [tex]-\frac{1}{(x+2)^{2}} = -1\\\\[/tex]
Let's solve for x
[tex]-\frac{1}{(x+2)^{2}} = -1\\\\\frac{1}{(x+2)^{2}} = 1\\\\(x+2)^{2} = 1\\\\x+2 = \pm\sqrt{1}\\\\x+2 = \pm1\\\\x+2 = 1 \ \text{ or } \ x+2 = -1\\\\x = -2+1 \ \text{ or } \ x = -2-1\\\\x = -1 \ \text{ or } \ x = -3\\\\[/tex]
The smaller x value is -3 while the larger x value is x = -1.

Luigi owns a few square tables and some chairs for his little restaurant. If he sets out individually with 4 chairs each, then he is 6 chairs short. If he always puts two tables together to create a bigger table with 6 chairs, then he has 4 chairs left over. How many tables does Luigi have?
It would be best if you explained your work. Any 'troll answers' will be reported.
Answers
Answer:
Suppose there are 10 tables. Putting 4 chairs at each table requires 4*10 = 40 chairs. Since this is 6 more chairs than he has, he must have 40 - 6 = 34 chairs.
Now suppose we put pairs of table together ("double tables"), so that 6 chairs can fit around each pair. With 10 tables, there will be 5 pairs, and with 6 chairs around each of these, we need 5*6 = 30 chairs. So 4 of the 34 chairs are left over. That's exactly what the problem said, so this is the answer.
Now, you may find that this check provides you with a model for the second equation you need to write! At least, I hope it clarifies what the problem means by "double tables".

A bag contains pennies, nickels, dimes, and quarters. There are 50 coins in all. Of the coins, 16% are pennies and 40% are dimes. There are 5 more nickels than pennies. How much money does the bag contain?
Answers
Answer:
$4.98
Step-by-step explanation:
50*16%=8 (pennies), 50*40%=20 (dimes)
8+5=13 (nickels), 50-(8+20+13)=9 (quarters)
So the money in total is 8*0.01+20*0.1+13*0.05+9*0.25=$4.98
ANSWER: $4.98
Steps for pennies:
1.) 50 * .16 = 8
8 pennies out of 50 coins
2.) 1 cent * 8 = 8 cents
Steps for dimes:
1.) 50 * .40 = 20
20 dimes out of 50 coins
2.) 10 cents * 20 = 200 cents = $2
Steps for nickels:
1.) 8 + 5 = 13
13 nickels out of 50 coins
2.) 5 cents * 13 = 65 cents
Steps for quarters:
1. 8 + 20 + 13 = 41
2. 50 - 41 = 9
3. 9 * .25 = $2.25
FINAL STEP:
8 cents + $2 + 65 cents + $2.25 = $4.98

Terrence buys a new car for $20,000. The value of the car depreciates by 15% each year. If f(x) represents the value of the car after x years, which function represents the car’s value?
f(x) = 20,000(0.85)x
f(x) = 20,000(0.15)x
f(x) = 20,000(1.15)x
f(x) = 20,000(1.85)x
Answers
Answer:
f(x) = 20,000(0.85)^x
Step-by-step explanation:
Given data
Cost of car P= $20,000
rate of depreciation r= 15%
Let us apply the depreciation formula
f(x) = P(1-r)^t
substitute
f(x) = 20000(1-0.15)^x
f(x) = 20000(0.85)^x
Therefore the correct expression is option 1
f(x) = 20,000(0.85)^x
