if f(x)=1/9x-2, what is f^-1(x)
Answer:
the inverse is 9x + 18
Step-by-step explanation:
switch 'x' with 'y'
y = 1/9x - 2
x = 1/9y - 2
solve for y now, start with multiplying each side by 9
9x = y - 18
y = 9x + 18
f^-1(x) = 9x + 18

Answer:

6 y = 6-5 1 (6, 1)
0 y = 0-5 -5 (0, -5)
5 y = 5-5 0 (5, 0)
-2 y = -2-5 -7 (-2, -7)
The graph of the line y = x-5 is attached below.
Step-by-step explanation:
Given the function
y = x-5
substitute x = 6 in the function
y = 6-5 = 1
so
y = 1
(x, y) = (6, 1)
substitute x = 0 in the function
y = x-5
y = 0-5 = -5
so
y = -5
(x, y) = (0, -5)
substitute x = 5 in the function
y = x-5
y = 5-5 = 0
so
y = 0
(x, y) = (5, 0)
substitute x = -2 in the function
y = x-5
y = -2-5 = -7
so
y = -7
(x, y) = (-2, -7)
Hence, the table becomes
x y = x-5 y (x, y)
6 y = 6-5 1 (6, 1)
0 y = 0-5 -5 (0, -5)
5 y = 5-5 0 (5, 0)
-2 y = -2-5 -7 (-2, -7)
The graph of the line y = x-5 is attached below.
Jayden and Carson are selling T-Shirts and sweatshirts with the school logo. Jayden sells 9 T-Shirts and 3 sweatshirts for 288$. Carson sells 1 T-Shirt and 6 sweatshirts for 270$. Find the selling prices of each item
Answer: cost of T-shirts = $18
cost of sweatshirt = $42
Step-by-step explanation:
Let the cost of T-shirts be x
Let the cost of sweatshirt be y
The information given in the question can be used to form an equation that'll be:
9x + 3y = 288 ...... i
1x + 6y = 270 ........ ii
Multiply equation i by 1
Multiply equation ii by 9
9x + 3y = 288 ....... iii
9x + 54y = 2430 ..... iv
Subtract iii from iv
51y = 2142
y = 2142 / 51
y = 42
The cost of a sweatshirt is $42
Since Carson sells 1 T-Shirt and 6 sweatshirts for 270$. The cost of a t-shirt will be:
= 270 - 6(42)
= 270 - 252
= $18
Tamika works in a shoe store and is paid a 12% commission on her sales. In January her sales total was $3740. To her nearest dollar how much did Tamika earn in commission for January?
A- $312
B- $449
C- $3291
D- $4189
Answer:D
Step-by-step explanation:
The total earn in commission by Tamika for January is $449.
What is percentage?A portion per hundred is what the percentage denotes. Percentage refers to one in a hundred. The sign "%" is used to denote it. Indicative percentages include: A fraction of ten percent is one tenth.
To find the percentage of a number between two numbers, number with the other and then multiply the result by 100.
Calculate the commission earned:
Tamika is paid a 12% commission on her sales.
In January her sales total was $3740.
12% of 3740 is,
=> (12×3740)/100 = 448.8
= 449
Therefore, the commission earned by Tamika for January is $449.

98 + g = 150
98 + g = 150. 98 + 98 + g = 150 minus 98. t = 52.
98 + g = 150. 98 minus 98 + g = 150 minus 98. t = 52.
98 + g = 150. 98 + 98 + g = 150 + 98. t = 52.

Compute $\sqrt{64} + \sqrt{225} - \sqrt{64 + 225}$.
Answer:
6
Step-by-step explanation:
Simplify the following:
sqrt(64) + sqrt(225) - sqrt(64 + 225)
Hint: | Evaluate 64 + 225.
64 + 225 = 289:
sqrt(64) + sqrt(225) - sqrt(289)
Hint: | Simplify radicals.
sqrt(289) = sqrt(17^2) = 17:
sqrt(64) + sqrt(225) - 17
Hint: | Simplify radicals.
sqrt(64) = sqrt(2^6) = 2^3:
2^3 + sqrt(225) - 17
Hint: | In order to evaluate 2^3 express 2^3 as 2×2^2.
2^3 = 2×2^2:
2×2^2 + sqrt(225) - 17
Hint: | Evaluate 2^2.
2^2 = 4:
2×4 + sqrt(225) - 17
Hint: | Multiply 2 and 4 together.
2×4 = 8:

find the measure of angle 8
Answer:
[tex]\displaystyle 114° = m\angle{8}[/tex]
Step-by-step explanation:
Alternate Interiour Angles are congruent, so set both expressions equivalent to each other:
[tex]\displaystyle [-5x - 4]° = [-9x - 60]° \hookrightarrow \frac{56}{-4} = \frac{-4x}{-4} \\ \\ -14 = x \\ \\ \\ 180° = [-9(-14) - 60]° + m\angle{8} \hookrightarrow 180° = [126 - 60]° + m\angle{8}; 180° = 66° + m\angle{8} \\ \\ 114° = m\angle{4}[/tex]
As you can see, we plugged the x-value into the expression for the sixth angle because if you recall, you can tell that angles [tex]\displaystyle 6\:and\:8[/tex]form a linear pair, and accourding to the Linear Pair Theorem, these angles are considered supplementary, therefore one hundred fourteen degrees is the measure of the eight angle.

Write an equation in point-slope form of the line that passes though the given points. Then, write the equation in slope intercept form.
(-1,-2) and (2,4)
Answer:
Please check the explanation.
Step-by-step explanation:
Given the points
(-1, -2)(2, 4)Finding the slope between (-1, -2) and (2, 4)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-1,\:-2\right),\:\left(x_2,\:y_2\right)=\left(2,\:4\right)[/tex]
[tex]m=\frac{4-\left(-2\right)}{2-\left(-1\right)}[/tex]
[tex]m=2[/tex]
Using the point-slope form
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope of the line and (x₁, y₁) is the point
substituting the values m = 2 and the point (-1, -2)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y -(-2) = 2(x-(-1)[/tex]
Thus, the point-slope form of the line equation is
[tex]y -(-2) = 2(x-(-1)[/tex]
now, write the slope-intercept form of the line equation y = mx+b
[tex]y-\left(-2\right)=2\left(x-\left(-1\right)\right)[/tex]
[tex]y+2=2\left(x+1\right)[/tex]
subtract 2 from both sides
[tex]y+2-2=2\left(x+1\right)-2[/tex]
Simplify
[tex]y=2x+0[/tex]
[tex]y = 2x[/tex]
Therefore, the equation in slope-intercept form is:
[tex]y = 2x[/tex]solve for x with 9x+1 and 88? i don’t know how to and i really need it. attachment has the picture.
Answer:
x = 5
Step-by-step explanation:
We know that adding up all the degrees in a triangle will give you 180. So, subtracting the given angle from 180 will give us the sum of the missing angles: 180 - 88 = 92.
Since the diagram shows us that the triangle is isoscles, we know that the missing two angles are the same and equivalent. So, in order to get the value of one angle, we divide the sum of angles by 2: 92/2 = 46.
Now that we've found the value of one angle, we set it equal to the equation given to find the value of x: 9x + 1 = 46.
Last but not least, solve for x: 9x = 45 --> x = 5
