F(x) = 2x + 1 when x <= -5
Now -10 is less than -5 so we plug x = -10 into 2x +1:-
f(-10) = 2(-10) + 1 = -19 answer
Now f(x) = x^2 when -5< x < 5
x =2 is within this range so f(2) = 2^2 = 4 answer
You can calculate the other 3 values by a similar method
Answer:
-5
Step-by-step explanation:
just trust me bro and goodluck.
10. When you are trying to find the area you multiply two of the sides together. So assuming that the area is a square then it would be 10 inches on each side.
Answer:
£39
Step-by-step explanation:
Given data
The sharing formula is
5:3
Let June get £x
Buck gets £26 more than june
Buck = x+26
Applying the part to part ratio method
5/3= x+26/x
cross multiply
3(x+26)= 5x
3x+78= 5x
78= 5x-3x
78= 2x
x= 78/2
x= £39
Hence June get £39
I was just learning that in class. It doesn’t make sense
