Domain of f(x) is all real numbers while the range is all real numbers greater than 6.
Answer:
t=2
Step-by-step explanation:
log4(7t+2)=2
Raise each side to the base of 4
4^log4(7t+2)=4^2
The log goes away
7t+2 = 16
Subtract 2 from each side
7t+2-2 = 16-2
7t = 14
Divide each side by 7
7t/7 = 14/7
t = 2
Answer:
(5x − 4)(x + 2)
Step-by-step explanation:
For the purpose, it is sufficient to make sure the middle terms match.
The middle term in the product of each of the answer choices is ...
-1+40 ≠ 6
-8+5 ≠ 6
-4+10 = 6 . . . . . the third selection is the one you want
-2+20 ≠ 6
Given parameters:
x = 150 minus 6 y
Interpreting this gives;
minus = subtraction = -
x = 150 - 6y
Now bring the variables together;
x + 6y = 150
The option that matches with this equivalent.
The other choices are wrong;
a, x + 150 = 6 y
x - 6y = 150 wrong
c. 2x + 3y = 75 mulitply through by 2;
2(2x + 3y) = 2(75)
4x + 6y = 150 wrong
d. 2x - 3y = 75
Multiply by 2;
2(2x -3y) = 2(75)
4x - 6y = 150
Answer: 50
Step-by-step explanation: 42x12=504. 504-4=500. 500/10=50.
