Answer:
(x - 2)/3
(x - 4)/-5 or (-x + 4)/5
Step-by-step explanation:
this is an inverse function, and to solve an inverse function you would :
swap x and g(x) without bringing the x coefficient with it, just simply swap the variables. Then, solve for g(x), and that's it
the first question's answer is :
g(x) = 3x + 2
x = 3(g(x)) + 2
x - 2 = 3(g(x))
(x - 2)/3 = g(x)
the second one is:
g(x) = 4 - 5x
x = 4 - 5(g(x))
x - 4 = -5(g(x))
(x-4)/-5 = g(x)
g(x) = 3x + 2
y = 3x + 2
x = 3y + 2
3y = x - 2
y = x/3 - 2/3
inverse g(x) = (x - 2) / 3
g(x) = 4 - 5x
y = 4 - 5x
x = 4 - 5y
5y = 4 - x
y = 4/5 - x/5
inverse g(x) = (4 - x) / 5

Product A sells 1.5 times more than Product B. Product B sells 70% less than Product C. Product C sold 34,000 units this month.
How many units of Product A were sold?
10,200
15,300 23,800 35,700 51,000
Answers
Answer:
15,300 units
Step-by-step explanation:
First, find how many units of Product B were sold:
34,000(0.3)
= 10,200
Find how many units of Product A were sold:
10,200(1.5)
= 15,300
So, 15,300 units of Product A were sold.
Product A sold 15,300 units that is 1.5 times more than product B
Given :
Product A sells 1.5 times more than Product B. Product B sells 70% less than Product C.
Product C sold 34,000 units this month
Product C sold = 34000
Product B is 70% less than product C
So, product B is 100-70% =30% of product C
[tex]Product B=\frac{30}{100} \cdot 34000\\Product B \; sold = 10200[/tex]
Lets find out product A sold
Product A sold = 1.5 times more than product B
[tex]Product A= 1.5 \cdot product B\\Product A=1.5 \cdot 10200=15300[/tex]
15,300 units of product A were sold.

The seats are numbers like a coordinate grid. Steve chooses the seat at (1, 2).
If Herb does not want to sit in the same vertical or horizontal row as Steve's seat.
now, we have,
in the same vertical or horizontal row means The x value should not contain the number 1, and, the y value should not contain the number 2 .
now, we get,
The x value should not contain the number 1, so we can eliminate choice c,
the y value should not contain the number 2 so we can Eliminate option A and D.
The only we one we have not eliminated is B,
and it follows the rules of not having 1 in the x value or 2 in the y value.
Therefore the answer is option B.
Hence, The solution is: B) (0,1) is the seat should he choose.

Let (2,-5) be a point on the terminal side of theta find the exact values of cos theta csc theta and tan theat
Answers
Answer:
Step-by-step explanation:
x = 2, y = -5
√(2²+(-5)²) = √29
cosθ = 2/√29 = (2√29)/29
sinθ = -5/√29
cscθ = 1/sinθ = -√29/5
tanθ = sinθ/cosθ = -5/2
The values of cos theta is 2/[tex]\sqrt{29}[/tex] , cosec theta is [tex]\sqrt{29} /5[/tex] and tan theta is 5/2 if the point on the terminal side of theta is (2,-5).
What is pythagoras theorem?It says that in a right angled triangle the square of the hypotenuse is equal to the sum of the square of base and square of height.
How to find values of trigonometric function?We have been given a point (2,-5) on the terminal side. Let us plot the point on the graph and join it with origin from both ends.
By pythagoras theorem we can easily find AC=[tex]\sqrt{5^{2}+2^{2} }[/tex]
AC=[tex]\sqrt{29}[/tex]
With the help of the sides of the triangle we can find the value of
cos theta=2/[tex]\sqrt{29}[/tex]
cosec theta=[tex]\sqrt{29}[/tex]/5
tan theta=5/2

How many gallons of a 5% bleach solution must be
added to 10 Gallons of a 20% bleach solution to
produce that is 15% bleach
Answers
Answer:
Step-by-step explanation:
10 gallons of the 20% solution contain 2 gallons of bleach.
x gallons of the 5% solution contain 0.05x gallons of bleach.
If the two are combined, the resulting 10+x gallons contain 2+0.5x gallons of bleach. The concentration is (2+0.05x)/(10+x).
(2+0.05x)/(10+x) = 15%
2+0.05x = 0.15(10+x)
2+0.05x = 1.5+0.15x
0.5 = 0.10x
x = 5
5 gallons of 5% solution is added to the 10 gallons of 20% solution.
