Y=(x+7)/8
Work:
Y=8x-7 —> x=8y-7
Solve for y
x+7=8y
y=(x+7)/8
Answer:
0.625
Explanation:
The image below was not posted for the but is needed to anser the question.
Further Explanation:
Mohamed carried out 24 trials of a simulation
Therefore, Total frequencies = 24
To get number of frequency greater than 3 we have to use the result in the result in the graph to obtain the estimate. Look at the graph below, when you count the dots that are on number of boxes purchased greater than 3, you will get 15.
Therefore, Number of frequency greater than 3 = 15
P(more than 3 boxes) = 15/24 = 0.625
Using the concept of function, it is found that:
- Graphs B, C, D and F are functions.
- Graphs A and E are not functions.
-----------------------------
- In a function, one value of the input can be related to only one value of the output.
- In a graph, it means that for <u>each value of x(horizontal axis), there can only be one respective value of y(vertical axis). </u>That is, if a vertical line is traced at a value of x, it can cross the function only once, that is, there cannot be points aligned vertically.
- In graphs B, C, D and F, it can be seen that <u>for each x value, there is only one respective y-value</u>, thus, they are functions.
- In graphs A and E, for <u>values of x,</u> such as x = 3 for both, there are <u>two respective values of y</u>, thus they are not functions.

(a) Without solving the equation we can't determine whether its true or false.
(b) If x = 3
4x + 1 = 2x + 5
4(3) + 1 = 2(3) + 5
12 + 1 = 15 + 5
13 = 20
No, if x = 3, the equation will not be true.
(c) 4x + 1 = 2x + 5
4x - 2x = 5 - 1
2x = 4
x = 4/2
x = 2
This shows that x = 2 makes the equation true.
