Step-by-step explanation:
1.25 each song
she bought 8 songs
1.25 x 8 = 10
10-20 = 10
The unknowns in this problem are A. The number of boys and the number of girls in the class.
We know there are 7 more girls than boys, but because we don't know how many boys there are, we don't know how many girls there are.
Answer:
When f(x) is replaced by f(x+5), it will shift the parent function '5 units' to the left.
Step-by-step explanation:
- We know that when we add a number 'a' to the input of the function, it would move the parent function 'a' units to the left.
In other words, the rule is:
- f(x + a) will shift the parent function 'a units' to the left.
Given the function
Thus, when f(x) is replaced by f(x+5), it will shift the parent function '5 units' to the left.
- The effect on the graph of the linear parent function is shown in the attached diagram.
In the graph, the red line is representing the parent function f(x) and the blue line is representing the effect on the graph i.e. f(x+5).
