Answer:
8n-5
Step-by-step explanation:
Find the difference between the numbers, +8 so 8n then subtract the diffference from the first number so 3 - 8= -5
The expression will be 8n - 5
1. Functions of the form f(x)=ax+b, where a is non zero, are called "linear functions" and the graphs of them are inclined lines.
2. If a>0, the line is increasing, so it gets higher as we move x to the right
If a<0, the line is decreasing.
3. There is no x we are not allowed to plug in the function: so Domain = all Real numbers
4. Since the lines are either increasing or decreasing, f(x), represented by the y values, take all values from -∞ to +∞. So Range = all Real numbers.
f(x)=4x (increasing line, 4>0) ,
g(x)=-x+4, h(x)=-4x (decreasing lines, -1<0, -4<0)
all f, g, h have Domain AND Range : All real numbers
Answer:
39,51
Step-by-step explanation:
Complementary angles add to 90 degrees
Let one angle be x
The other angle is x+12
x+ x+12 = 90
Combine like terms
2x+12 = 90
Subtract 12 from each side
2x+12-12 = 90-12
2x = 78
Divide each side by 2
2x/2 = 78/2
x =39
The other angle is 39+12 =51
If -3 + i is a root of the polynomial function f(x), -3 - i must also be a root of f(x)
<h3>How to determine the true statement?</h3>
The root of the polynomial function is given as:
-3 + i
The above root is a complex root.
If a polynomial has a complex root, then the conjugate of the root is also a root of the function
The conjugate of -3 + i is -3 - i
Hence, if -3 + i is a root of the polynomial function f(x), -3 - i must also be a root of f(x)
