If f(x) = 8 -3 and g(x) = 3x2 + x-6, find (f + g)(x).

Marizza181 [45]

Answer:

Step-by-step explanation:

(f+g)(x) basically means to "ADD" f(x) and g(x).

We have

$f(x)=\frac{x}{2}-3$

and

$g(x)=3x^2+x-6$

Now we simply add these two, adding like terms as shown below (and simplify):

$(f+g)(x)=f(x)+g(x)\\=(\frac{x}{2}-3)+(3x^2+x-6)\\=3x^2+\frac{1}{2}x+x-3-6\\=3x^2+\frac{3}{2}x-9$

Correct answer is D

This figure shows circle Z with chords AB and RS . mAR=55° mRB=66° AB=8 m RS=8 m What is mRS?

Alina [70]

M AR = 55°
m RB = 66°
Like AB=8 m =RS →m RS = m AB

m AB = m AR + m RB
m AB = 55° + 66°
m AB = 121°

m RS = m AB
M RS = 121°

Answer: m RS is 121°

Joe collected 94 stamps altogether. He collected 27 in April and 34 in May. How many did he collect in June?

inna [77]

If Joe collected 94 stamps which are in April May and June, we could make an equation like this: A + M + J = All stamps

Plug in the values:
$27 + 34 + j = 94$
Isolate J:
$j = 94 - 27 - 34$
Combine like terms:
$j = 33$
He collected 33 stamps in June.
