Let f(x)=x + 3 and g(x) = x^2 - x. Find and simplify the expression.(f+g)(-3)=​

Mathematics
1 answer:
Gnoma [55]3 years ago

Answer:

12

Step-by-step explanation:

f(x)=x+3

g(x)=x^2-x

[f(x)+g(x)]=[x+3]+[x^2-x]

[f(x)+g(x)]=x+3+(x^2)-x  

x and -x will be cancelled; hence

[f(x)+g(x)]=x^2+3

f(x)+g(x)=(f+g)(X)

(f+g)(x)=x^2+3

(f+g)(-3)=(-3^2)+3

(f+g)(-3)=9+3

(f+g)(-3)=12

6a+4=61/3+4<br> I don’t know what I’m doing wrong because I keep getting 10 1/3
Vlad1618 [11]

Answer:

a = 3 7/18 or 3.388889

Step-by-step explanation:

First, you want to get the a by itself, so you would subtract 4 from the left side of the equals sign.

6a + 4 = 61 / 3 + 4

    -4                   -4

6a = 61 / 3

By doing that, they cancel each other out, so you are left with

6a = 61 / 3

Then you want to get a by itself, so you divide 6 from both sides.

6a / 6 = 61 / 3  /  6

Remember that 6 can also be written as 6/1

Remember that dividing a fraction is multiplying the reciprocal.

6a / 6 = 61 / 3  /  6 / 1

When dividing fractions remember to Skip the first fraction, Flip the second fraction, and Multiply the two fractions together.

61 / 3      x        1 / 6

skip   multiply   flip

Multiply across the top, and across the bottom.

61(1) and 3(6)

Then you get

61 / 18

So a = 61 / 18

If you want to convert that to a mixed number, it would be 3  7 / 18

If you want that in a decimal, it would be 3.388889
