the answer is y=2x-12

All that I know is that since it is parallel the slopes have to be the same. So it would have to be y=2x+b. And in this I think b would be 4. So the final answer I think should be y=2x+4.

I hope I helped!!

The value of x the function when x = -7.5 is 34.5

<h3>Functions and values</h3>

Functions are written in terms of variables

Given the expression  –3.8x + 6, when the value of x is -7.5, hence;

f(x) =  –3.8x + 6

f(-7.5) = -3.8(-7.5) + 6

f(-7.5) = 28.5 + 6

f(-7.5) = 34.5

Hence the value of x the function when x = -7.5 is 34.5

There are a total of 122 countries in Africa, Europe, and North America (as of 2003). Europe has twice as many countries as Nort
Eddi Din [679]
A + E + N = 122
E = 2N
A = 7 + E....A = 7 + 2N

(7 + 2N) + 2N + N = 122
5N + 7 = 122
5N = 122 - 7
5N = 115
N = 115/5
N = 23 <== North America

E = 2N
E = 2(23)
E = 46 <== Europe

A = 7 + E
A = 7 + 46
A = 53 <=== Africa

Two dice are rolled. What is the probability that the sum of the numbers is exactly 10? What is the probability that the sum of
never [62]

Answer:

exactly 10: 8.33 %

at least 10: 16.66 %

Step-by-step explanation:

first we have to see the amount of favorable results

4+6 = 10

6+4 =10

5+5=10

then we have to see the amount of possible results

Each dice has 6 faces and there are 2 dice, so if we make 6 ^ 2 we will get the number of possible combinations

6^2 =

6*6 = 36

Now we only do the number of favorable results on the possible results and multiply it by 100 and obtain the probability

100*3/36 = 8.33 %

we do the same for those greater than or equal to 10

4+6 = 10

6+4 = 10

5+5 = 10

6+5 = 11

5+6 = 11

6+6 = 12

100*6/36 = 16.66 %

If fx = 3x over 5 +3 which of the following is the inverse
Alborosie

Answer:

f^(-1)(x) = -3x/(3x-3)

Step-by-step explanation:

1) replace f(x) by y

● y = 3x/(5x+3)

2) exchange x and y

● y = 3x/(5x+3)

● x = 3y / (3y +3)

3) solve for y

● x = 3y / (3y +3)

● x (3y +3) = 3y

● 3xy + 3x = 3y

● 3xy - 3y = -3x

● y (3x - 3) = -3x

● y = -3x /(3x-3)

4) replace y with f^(-1)(x)

● y = -3x/(3x-3)

● f^(-1)(x) = -3x/(3x-3)
