Answer:
x = 8/3
Step-by-step explanation:
(When solving for a variable, always do the opposite of PEMDAS)
-5 + 4 = 3x - 9
-1 = 3x - 9
8 = 3x
8/3 = x
Answer:
The function y = sec(x) shifted 3 units left and 7 units down .
Step-by-step explanation:
Given the function: y = sec(x)
- If k is any positive real number, then the graph of f(x) - k is the graph of y = f(x) shifted downward k units.
- If p is a positive real number, then the graph of f(x+p) is the graph of y=f(x) shifted to the left p units.
The function
comes from the base function y= sec(x).
Since 3 is added added on the inside, this is a horizontal shift Left 3 unit, and since 7 is subtracted on the outside, this is a vertical shift down 7 units.
Therefore, the transformation on the given function is shifted 3 units left and 7 units down
Answer:
B.
Step-by-step explanation:
Here the best method to solve is by substituting the end values of the set in each option , otherwise it will a time consuming problem.
Now substitute x=-4 in all the options
A.
16+8-8=16>0
so out of option A and C option C is correct.
B.
16-8-8=0 which means for the values of x>-4
is less than 0
Now substitute x=2 in all the options
A.
4-4-8=-8<0 . so option A and C both are incorrect.
B.
4+4-8=0 which means for the values of x<2
is less than 0
Therefore the correct option is B
Answer:
subtract 2.4 from both sides, simplify to -3x=16.8, divide by -3, simplify to x=-5.6.
Step-by-step explanation:
-3x + 2.4 = 19.2
v <u>-2.4</u> <u>-2.4</u>
v 0 16.8
<u>-3x</u>=<u>16.8</u>
-3 -3
x=-5.6
