Answer:

0.6

Step-by-step explanation:

Put these values in order from least to greatest. 7/8,84%,0.821

Vitek1552 [10]

Answer:

0.821, 84%, 7/8

Step-by-step explanation:

So, first, you have to convert them all to the same form. We'll be using decimals.

7/8= 0.875

84%= 0.84

0.821

Now, just put them in order and use the original form in your final answer.

0.821, 0.84, 0.875

Given that f(x) = x2 –3x – 40 and g(x) = x +5, find (f +g)(x) and express

Svetlanka [38]

Answer:

$(f+g)(x)=x^2-2x-35$

Step-by-step explanation:

So we have the two functions:

$f(x)=x^2-3x-40\text{ and } g(x)=x+5$

And we want to find (f+g)(x). This is the same as:

$(f+g)(x)=f(x)+g(x)$

Substitute:

$=(x^2-3x-40)+(x+5)$

Combine like terms:

$=x^2+(-3x+x)+(-40+5)$

Add:

$=x^2-2x-35$

And we're done!
