Answer:
a = -11, 17.
Step-by-step explanation:
-7 = |a-3| / -2
Multiply both sides by -2:
|a - 3| = 14
So a - 3 = 14
Giving a = 17
or
a - 3 =- -14
giving a = -11.
Checking these values:
-7 = |17-3| / -2 = 14/-2 = -7
- so a = 17 is a solution.
-7 = |-11-3| / -2 = 14/-2 = -7
so a = -11 is also a solution.
Answer:
3n +3
Step-by-step explanation:
7n-(4n-3)
Distribute the minus sign
7n -4n +3
3n +3
Answer:
f(-3) = 7
Step-by-step explanation:
For these types of questions, you need to replace the x's in the equation with whatever is inside f(x)
So if its f(5) you would sub 5 into where all the x's are
Step-by-step explanation: i think it is B
You can conclude that AE = DE because the triangles are about equal
