Answer:
1. 2x
2. 22
Step-by-step explanation:
question 1
f(x)-g(x)
5x-3-(3x-3)
5x-3-3x+3
5x-3x-3+3
2x+0
2x
question 2
f(x)=y
f(-4)= -5(-4)+ (-4/-2)
= 20 + 2
=22
Answer:
13.4
Step-by-step explanation:
AB =2DC
So, DC=AB/2
Now, AB/AC=DE/DC
AB/28=13/(AB/2)
AB²=13×28×2
AB=√728
AB=26.98
now, DC=AB/2
=13.4
multiply 6 x 6 to get 36 and 7 x 11 to get 77.
6/7 x 6/11 = 36/77
Y = -5x -5
To check, we can insert 0 for y and -1 for x
0 ? (-5X-1) - 5
0 ? 5 - 5
0 = 0
So yes, the equation is correct
