Answer:
Step-by-step explanation:
If it's (-216):
(-216) + 3(5 - 4 x 2)
(-216) + 3( -3)
(-216) -9
-225
If it's -2(16):
-2(16) + 3(5 - 4 x 2)
-2(16) + 3(-3)
-32 - 9
-41
Answer:
Hence The composition 
of the given function is 
.
Step-by-step explanation:
Given:
We need to find 
.
Solution:
Now we can say that;
= 
Now Applying distributive property we get;
Now Solving the exponent function we get;
Hence The composition of the given function is .
4y2=256
4 x 2 = 8
256 divided by 8
Y=32
Answer:
a = - 4, b = 5
Step-by-step explanation:
Expand the left side, then compare the coefficients of like terms.
- 3(2x² + ax + b)
= - 6x² - 3ax - 3b, compare to - 6x² + 12x - 15
Compare coefficients of x- terms
- 3a = 12 ( divide both sides by - 3 )
a = - 4
Compare constant terms
- 3b = - 15 ( divide both sides by - 3 )
b = 5
Place the x (1.5) and y (5) values into the equation, and solve. If the statement you get is true, it is a solution.
2x - y = -1
2(1.5) - 5 = -1
3 - 5 = -1
-2 ≠ -1
Since this is a false statement, negative 2 is not equal to -1, the ordered pair is NOT a solution. I hope this helps and have a great day!
