Answer:
The inverse is 5/(2-x)
Step-by-step explanation:
Firstly, let us represent the inverse as y
thus;
y = (2x+ 1)/x-4
y(x-4) = 2x + 1
xy - 4 = 2x + 1
2x - xy = -4-1
2x-xy = -5
x(2-y) = 5
x = 5/2-y
Now, switch the alphabets again
y = 5/(2-x)

[tex]18 \div 9 = 2 \\ 6 \div 3 = 2[/tex]
Answer:
C
Step-by-step explanation:
Area of the original one = 9 * 3 = 27 cm^2
Area of the scaled one = 18 * 6 = 108 cm^2
108 / 27 = 4

A side of the triangle below has been extended to form an exterior angle of 128°. Find the value of x.
the value of x.
Answer:
x = 104
Step-by-step explanation:
The exterior angle is equal to the sum of the opposite interior angles
24+x = 128
Subtract 24 from each side
24+x-24 =128 -24
x =104

*please help and explain how you got the answer!*
Answer:
0
Step-by-step explanation:
A= (4-1)^3
simplify A to be 3^3
Which gives us 27
B=(2*3)^2-9
simplify B
first multiply the 2 numbers in paranthesis which gives us 6. raise it to the power of 2 which is 39 and then subtract 9. Gives us 27.
C=15^3*4-12
Simplify the exponent first. 3*4 gives us 12 and 12-12 equals 0. Anything raised to the power of 0=1
If A-B^C is the equation we can write 27-27 raised to the power of 1 which is 0

Can I please get Brainliest!
Answer:
This equation is invalid, therefore there is no solution.
Step-by-step explanation:
2x + 8 = 2(x + 4)
8 + 2x = 2(x + 4)
8 + 2x = 2(4 + x)
8 + 2x = (4 * 2 + x * 2)
8 + 2x = (8 + 2x)
8 + 2x + -2x = 8 + 2x + -2x
8 + 0 = 8 + 2x + -2x
8 = 8 + 2x + -2x
8 = 8 + 0
8 = 8
This equation is invalid, therefore there is no solution.

6x - 2y = -22
х+4y = -8
Answer:
x = -4 y = -1
Step-by-step explanation:
x + 4y = -8
4y = -x - 8
y = -1/4x - 2
6x - 2(-1/4x - 2) = -22
6x + 1/2x + 4 = -22
13/2x + 4 = -22
13/2x = -26
x = -4
(-4) + 4y = -8
-4 + 4y = -8
4y = -4
y = -1
Answer:
x = -4 y = -1
Step-by-step explanation:
Solve for each variable by creating an equation and plugging it in to the other given equation.
- Equation to solve for x: x = -4y - 8
- Plug this equation into the other, solving for y so you have:
6(-4y-8)- 2y = -22 => -24y - 48 - 2y = -22 => -26y = 26 => y = -1
- Take this value and plug into the equation we created for x:
x = -4(-1) - 8 => x = 4 -8 => x = -4
- Check your work with given equation 6x -2y = 22:
6(-4) - 2(-1) = -22 => -24 +2 = -22 => -22 = -22

Solve for x. Round to the nearest tenth. Help
Answer:
26
Step-by-step explanation:
cosθ = adjacent / hypotenuse
cos(26) = 18 / x
x= 18 / cos(26)
x= 27.82418 ≈ 20 (to nearest tenth)
Answer:
x ≈ 20
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos26° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{18}{x}[/tex] ( multiply both sides by x )
x × cos26° = 18 ( divide both sides by cos26° )
x = [tex]\frac{18}{cos26}[/tex] ≈ 20.0 ( to the nearest tenth )

Step-by-step explanation:
It appears as though we're to assume that KM is a diameter, through circle center point N. That makes triangle KLM a right triangle, so angle K is the complement of angle M.
∠K = 180° -63° = 27°
Can someone help me with this. Will Mark brainliest.
Answer:
Radius
Step-by-step explanation:
Any segment with one endpoint at the center of the circle and the other endpoint on the circle is the radius. This information is very important, because when you want to find the area of a circle you multiply the radius by itself twice then multiply that by pi. The diameter (second option) is a segment where one endpoint is on the circle and the other endpoint is on the other side of the circle. The diameter is twice the radius. Good luck!
Jim orders prints from a website. The site charges him $6.95 a month and $0.04 for each print he orders.
Enter an equation that can be used to find the number of prints, P, Jim ordered last month if the website charged
him $17.79.
Enter the number of prints Jim ordered last month.
Answer:
271 prints.
Step-by-step explanation:
So to answer the question, we need to first write a formula to find the answer.
We know that the starting price per month is 6.95 dollars.
The full price is 17.79 dollars.
So we can start this off by writing:
17.79=6.95
Now, every time Jim prints, he charges 0.04 dollars. This will add to the orginal cost, which is 6.95. And remember this isnt a single payment, but a payment that varies depending on the amount of paper, p. So we can write this as:
17.79=6.95+0.04p
6.95 wont ever change, hense why it doesnt have a variable. 0.04 however, varies depending on the amount of paper, and thats why we included the variable p.
These two values combined make 17.79, hense why it is on the opposite side of the equals sign.
So, now we need to find how many papers, p, were printed.
To find this, lets just take our equation, and solve for P like an ordinary problem:
17.79=6.95+0.04p
So first off, lets subtract the 6.95 from both sides, because that iscolates the 0.04p, which contains the variable.
Now we have:
10.84=0.04p
Now, we could divide both sides by 0.04.
But remember, the whole point of doing this is to make 0.04p into 1p.
So another way of doing this is multiplying the 0.04 by 25, since 0.04*25=1.
So lets multiply both sides by 25:
10.84*25 is 271.
Since 10*25 is 250
And
.84*25 is 21.
So now we know:
271=1p
So 271 is your answer!
Hope this helps!
The equation that can be used to find the number of prints, p, is $17.79 = $6.95 + $0.04p and Jim ordered 271 prints last month.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
We can write an equation to represent the total cost that Jim was charged by the website for last month's prints, p to represent the number of prints he ordered:
Total cost = Monthly fee + Cost per print x Number of prints
Using the values given in the problem:
$17.79 = $6.95 + $0.04p
To solve for p, one side of the equation. First, we can subtract $6.95 from both sides:
$10.84 = $0.04p
Then, we can divide both sides by $0.04:
p = 271

Out of 200 students in a school, 30 have brown sandals. What is the probability that a student chosen at random would have brown sandals?
Answer:
There is a 15% chance a student chosen at random would have brown sandals.
Step-by-step explanation:
The required probability will be 0.15 that a student chosen at random would have brown sandals.
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
the probability = number of favorable outcomes / total number of outcomes.
We have been given that out of 200 students in a school, 30 have brown sandals.
To determine the probability that a student chosen at random would have brown sandals.
The probability = number of favorable outcomes / total number of outcomes.
The probability = 30 / 200
The probability = 0.15
Thus, the required probability will be 0.15 that a student chosen at random would have brown sandals.
