Answer:

A) 48

B) -30

Step-by-step explanation:

Hello!

<h2>Part A</h2>

To compute f(-1) and f(5), we simply replace x with -1 and -5.

<h3 /><h3>Calculate</h3>
  • f(-1) + f(5)
  • ((-1)^2 - 1 + 9)+ (5^2 +5 + 9)
  • (9)+(39)
  • 48

The answer to A is 48

<h2>Part B</h2>

We have the values for f(-1) and f(5), so we just switch the operation

  • (9) - (39)
  • -30

The answer to B is -30

Please help me with this word problem!
IRISSAK [1]

Answer:

f(g)=25g

Step-by-step explanation:

Let g be the number of gallons so f(g) is the number of miles traveled per g gallons.

We know for our problem that Brian's car gets 25 miles per gallon. Since the gallons is represented by g, his car will travel a total distance of 25g (where g is the number of gallons.

We also know that the total distance is given by f(g), so we can put the two expressions together to get our function:

f(g)=25g

Let's check:

- If he uses 1 gallon (g=1), so

f(1)=25(1)

f(1)=25 miles

He will travel 25 miles with one gallon.

- If he uses 2 gallons (g=2), so

f(2)=25(2)

f(2)=50

He will travel 50 miles with two gallon.

Answer: 105 degrees

Step-by-step explanation:

so, since it is a parallelogram, adjacent angles are equal. so, we know that angle S and angle U are equal. that means we can subtract 150 from the 360 degrees of the full parallelogram. so, that leaves 210 degrees to work with. since it is shared amongst the other two equal angles, we just divide it by 2. so, that's how we get the answer.
