X+20=104
-20 -20
0. 84
X=84
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
Answer:
Slope is -3.
Step-by-step explanation:
The equation to get the slope is y2-y1/x2-x1. So, plug in the points to the equation. -7-8/7-3 = -15/5 = -3/1 = -3.
The chocolate chip cookies of the cookie's club are not perfect according to Wendy, as the ratio of the chocolate chips to the cookies is more than that of a perfect cookie.
To solve this problem we have to learn about ratio. A ratio is an ordered pair written as or a:b where . It can also be defined as the number of times one number is contained in another number.
In the given problem Wendy thinks that a 353535 chocolate chips are essential for 555 cookies so that each cookie is perfect. Now let us find the ratio of the chocolate chips for each cookie.
Ratio=
or, Ratio=637:1
Therefore according to Wendy, a perfect chocolate chip cookie must have 637 chocolate chips.
Now let us find the ratio of the chips to cookie of the Cookie's Club.
Total chocolate chips=100100100
Total cookie=151515
Ratio of chips to cookies= which can be simplified to .
Therefore required ratio=
or, approximately ratio=
Now
Therefore the chocolate chip cookies of the cookie's club are not perfect according to Wendy.
