The value of the expression f(5) + j(-2)  is -8 where f(x)=12-3x and j(x)=x² + 4x - 1

<h3>How to solve the equation?</h3>

The expression is given as:

f(5) + j(-2)

Where f(x)=12-3x and j(x)=x² + 4x - 1

Calculate f(5) and j(-2)

f(5)= 12 - 3(5) = -3

j(-2) = (-2)² + 4(-2) - 1 = -5

So, we have:

f(5) + j(-2)  = -3 - 5

Evaluate

f(5) + j(-2)  = -8

Hence, the value of the expression f(5) + j(-2)  is -8

Question
Natali [406]

Answer:

42

Step-by-step explanation:

Since Gabrielle is 7 years older than Mikhail, we subtract 7 from 91. Then we divide it by 2. So 84/2=42. Since Gabrielle is 7 years older we add 7 to 42. She is 49 and Mikhail is 42 years old. To double check our answer we should add both of the ages we got to make sure they add up to 91, so 42+49 is 91.

How would I do this?
iogann1982 [59]

Answer:

A triangle is normally 180 degrees only.

Step-by-step explanation:

So, you have one 90 degree angle, and on 42.7 degree angle. Add those up to 132.7. Now, you would subtract that from 180, meaning that the answer is A, 47.3.


Good luck :DD

If you know two points on a line, how can you find the rate of change of the variables being graphed?
Leto [7]
Count the difference of the x values between the two points (the run of the slope) and the difference of the y values between the two points (the rise of the slope). That would get you the rate of change, or slope, of the line.
