Answer:
option d
Step-by-step explanation:
We are given with three function
Plug in x=-2 in first function
f(x)= 3 so f(-2) = 3
Plug in x=-2 in second function
Plug in x=2 in second function
Plug in x=2 in third function
f(x)= 2x-3
f(2)= 2(2) -3 = 1
We can see that f(-2)=3 is same for first and second function
also f(2) = 1 is same for second and third functions
So the graph is continuous
option D satisfies the points
Answer: To to find the percentage, you simply need to divide 45 by 60:
Step-by-step explanation:
45/60= .75
Move the decimal from the .75 over 2 times which would get you 75% on his test. So he got a 75%
The answer would be p= -2
To check it:
-2(5(-2) - 3) = 26
-2(-10-3) = 26
-2(-13) = 26
26 = 26
Answer:
7(x+4)-2/3 (x-6) < 2[x-3(x+5)]
Do it 1 step at a time.
7(x+4)-2/3 (x-6) < 2[x-3x-15]
7x+28 - 2/3 (x-6) < 2[x-3x-15]
I'll assume you mean (2/3)*x-6)
---
7x+28 - (2x/3) - 4 < 2[-2x-15]
7x+24 - (2x/3) < -4x-30
Add 4x
11x+24 - (2x/3) < -30
Add 30
11x + 54 - (2x/3) < 0
Multiply thru by 3
33x + 162 - 2x < 0
31x < 162
x < 162/31
