Answer:
4
Step-by-step explanation:
To find the scale factor divide the new length by the original.
10/ 2.5 = 4
The scale factor is 4.
Answer:
1
Step-by-step explanation:
If you plug 1 into f(x) you get 6 so f^-1 is 1
x- intercept = 5/2
y - intercept = 5
Step-by-step explanation:
the intercepts of a line are found by plugging in x=0 and y = 0
For x-intercept, we put y = 0
and
For- y-intercept we put =0
Given equation is:
Dividing both sides by -4
Putting x = 0
Dividing both sides by 2
So,
x- intercept = 5/2
y - intercept = 5

Answer:
-n^2 - 5n + 24
Step-by-step explanation:
Let the number be n.
Then the sum of that number and 3 is n+3.
The difference of 8 and the number is 8 - n.
Then we get the expression (n + 3)(8 - n).
Performing the indicated multiplication, we get:
8n - n^2 + 24 - 3n, or
-n^2 - 5n + 24
Nothing more can be done, as this is not an equation, but rather an expression.
