Simplify
2×3^x - 3^x-1 / 18^x × 2^-x
Step-by-step explanation:
Collect like terms: 6∧x - 3∧x - 1/ 18∧x · 2
3∧x - 1/ 18∧x · 2
Calculate the product: 3∧x - 2/ 18∧x
Find common denominator: 54∧x/ 18∧x - 2/ 18∧x =
54∧x - 2/ 18∧x
Write an equation in slope-intercept form of the line that passes through the given points. 0,4 4,2
First, find the slope: m = Δy/Δx = (2-4)/(4-0) = -0.5
The "intercept" in the slope-intercept form of a line is the y-intercept. And at the y-intercept, x = 0. Conveniently, one of our points has an x = 0, i.e., the point (0,4). So, our equation would be y = -0.5x + 4.
If you wanted to double-check, you could use the point (4,2) to find the point-slope equation of the line and see if it matches up with the slope-intercept form above. Given a slope of -0.5 and a point (4,2), our point-slope equation would be y - 2 = -0.5(x - 4). If we expand this, we get y - 2 = -0.5x + 2. Solving for y, we obtain y = -0.5x + 4.
Thus, y = -0.5x + 4 would be our equation.
Leila needs to buy plastic spoons. Brand A has a box of 25 spoons for $1.97. Brand B has a box of 48 spoons for $2.98. Find the unit price for each brand. Then state which brand is the better buy based on the unit price. Round your answers to the nearest cent.
Answer:
The unit price is the price of a single unit.
To find it, you need to find the quotient between the total price and the number of objects you get for that price.
Brand A:
You get 25 spoons for $1.97
Then the unit price is:
unit price of brand A = $1.97/25 = $0.079
Brand B:
You get 48 spoons for $2.98
Then the unit price is:
unit price of brand B: $2.98/48 = $0.062
Here we can see that the unit price for brand B is smaller, then the better buy is brand B.

I’m studying and I have trouble with this problem and I need an explanation. Please help me! Thank you
Answer:
Step-by-step explanation:
Im going to assume they want x+108.
You have 2 expressions sitting on a line, so when added to each other they must = 180
So add and set up an equality
x+108+x+78=180
Combine like terms
2x+186=180
Solve
2x+186=180
-180 -180
2x+6=0
-6 -6
2x=-6
________
2
x=-3
Substitute X for -3
-3+108=

2. On the Internet, you find an Latin quiz with 10 matching vocabulary questions. Your 3 year old niece randomly matches the
words with the definitions. What is the probability that she makes 100 on the quiz?
Does the order matter? Yes -
This is a permutation
Will all of the words be matched? Yes -
Can we use factorials? Yes -
How many different ways can the answer key be arranged?
P(all correct)
(Enter your answer as a reduced fraction using/ for the fraction bar.)
Answer:
Assume that there is a Latin quiz with 10 matching vocabulary questions, and your niece try to match them randomly. Then, the probability that she gets the first item right is
1
10
since there is only one correct answer for this item out of 10 options. Now, the probability that she gets the second item right is
1
9
since there is only one correct option and there is only 9 options left to choose from. So, in a similar fashion, the probability that she will get the third item correct is
1
8
, the fourth item correct is
1
7
and so on. Therefore, the probability that she will match them all correctly (getting a 100 on the quiz) is equal to

Answer:
-37
Step-by-step explanation:
f(x) = - 9x + 8
f(5) = - 9*5 + 8 = -37
Answer: -37

f(5) = -9x + 8
f(5) = -9(5) + 8
f(5) = -45 + 8
f(5) = -37
a/ab-bsquare + b/ab-asquare?
Answer:
[tex]\dfrac{(a+b)}{ab}[/tex]
Step-by-step explanation:
The given expression is :
[tex]\dfrac{a}{ab-b^2}+\dfrac{b}{ab-a^2}[/tex]
It can be solved as follows :
[tex]\dfrac{a}{ab-b^2}+\dfrac{b}{ab-a^2}=\dfrac{a}{b(a-b)}+\dfrac{b}{a(b-a)}\\\\=\dfrac{a}{b(a-b)}+\dfrac{b}{-a(-b+a)}\\\\=\dfrac{1}{a-b}(\dfrac{a}{b}-\dfrac{b}{a})\\\\=\dfrac{a^2-b^2}{ab(a-b)}\\\\=\dfrac{(a-b)(a+b)}{ab(a-b)}\\\\=\dfrac{(a+b)}{ab}[/tex]
So, the solution of the given expression is equal to [tex]\dfrac{(a+b)}{ab}[/tex].
Solve the equation. Graph the solution on a number line. (You don’t have to graph it, I just need the equation answer.)

AC =using the Distance Formula
A. 10
B. 5
C. 15
Answer:
√41
Step-by-step explanation:
Here we want to find the value of AC
A = (-4,0)
C = (1,4)
The distance formula is;
D = √(y2-y1)^2 + (x2-x1)^2
D = √(4-0)^2 + (1-(-4)^2
D = √4^2 + 5^2
D = √(16+25)
D = √41
