Answer:

<h2>(f - g)(x) = - x² + 2x + 3</h2>

Step-by-step explanation:

f(x) = 2x + 2

g(x) = x² - 1

To find (f - g)(x) subtract g(x) from f(x)

That's

(f - g)(x) = 2x + 2 - [ x² - 1]

(f - g)(x) = 2x + 2 - x² + 1

Group like terms

That's

(f - g)(x) = - x² + 2x + 2 + 1

We have the final answer as

<h3>(f - g)(x) = - x² + 2x + 3</h3>

Hope this helps you

IRISSAK [1]
Jose is false because the sun which makes it a day only shines none side of the earth while the moon is on the other side so on the other half of the hemisphere the days would be getting shorter while the days get longer on the other half of the hemisphere.

Find the value of x!!!!!
tino4ka555 [31]

Answer:

96 degrees

Step-by-step explanation:

The 144 degrees is on a straight line, meaning the angle next to it inside the triangle and 144 are supplementary. They add up to 180 degrees.

Coincidentally, the other two angles plus the third, unlabeled angle will add up to 180 degrees as well, meaning that the the 48+x = 144 degrees (according the property of equality, which is if a=b and b=c, then a=c). Solve for x from there:

x = 144-48

x = 96
