<span> 5-X=-6-3X/2
First: You would get rid of your fraction by multiplying each side by two.
You would get: 2(5-x)=-6-3x > which equals 10-2x=-6-3x
Next: You would combine like terms, but we are going to do your x's first. You would add your -3x to both sides which makes it a positive.
You would get: 10-x=-6
Next: What you would do is subtract 10 on both sides of the equal sign.
You would get: -x=-16
Last: You would divide by -1 on each side of the equal sign to get your x alone.
Your answer would be: x=16

Answer:
y = √(x - 2) / 2
Step-by-step explanation:
y = 2x^2 + 2.....switch ur x and y and solve for y
x = 2y^2 + 2
x - 2 = 2y^2 ...divide both sides by 2
(x - 2) / 2 = y^2...now take the sqrt of both sides, eliminating the ^2
(√ (x - 2) / 2) = y
divide the ratio be common factors. for example, 4.
168 : 56
42 : 14 divide by 7
6 : 2 divide by 2
3: 1
The answer is three
Answer:
The answer is 2nd point
Step-by-step explanation:
In this question, inverse of f(x) is equals to g(x). First, you must know how to find the inverse of f(x). In order to find the g(x), you must let f(x) = y and make x thd subject :
1.
Let y = (10x+9)/8
y = (10x+9)/8
8y = 10x + 9
8y - 9 = 10x
(8y-9)/10 = x
x = (8y-9)/10
g(x) = (8x-9)/10 (Remember to convert y back to x)
2.
Let y = x - 9
y = x - 9
y + 9 = x
x = y + 9
g(x) = x + 3
Next, by looking in no.1, the inverse of f(x) is wrong and in no.2, it shows the correct form of inverse. So only 2 is an inverse function
Simple, just divide the number by the percentage and you get the original number. You can check it by multiplying the original number of 272 by 55% or .55 to get 150.
150/.55 = 272
