Answer:

(f – g)(2) =  12.

Step-by-step explanation:

Given  :  f(x) = 3x²+1 and g(x) =1-x .

To find : which expression is equivalent to (f – g)(2).

Solution : We have given   f(x) = 3x²+1  and g(x) = 1-x .

(f – g)(2) = f (2 ) - g(2) .

g(x) =  1-x .

Plug x = 2 .

g(2) = 1 - 2 .

g(2) =  - 1.

For    f(x) =3x²+1

Plug x = 2

f( 2) =3 (2)²+1.

f(2) = 12 + 1.

f(2) =  13 .

Then , (f – g)(2) = f (2 ) - g(2) .

Plugging the values

(f – g)(2) = -1 +  13

(f – g)(2) = 12

(f – g)(2) =  12.

Therefore,  (f – g)(2) =  12.

A car dealership sells SUVs and passenger cars . For a recent year, 80 more SUVs were sold than passenger cars. If a total of 51
MAVERICK [17]

Answer:

295 SUVs were sold, and 215 passenger vehicles.

Step-by-step explanation:

Let s and p represent the number of SUVs and p the number of passenger cars.  

Then s = p + 80 and s + p = 510.

Substitute p + 80 for s in the second equation, obtaining:

p + 80 + p = 510, or:

2p = 430

Dividing both sides by 2 isolates p:  p = 215.

Since s = p + 80, we add 80 to 215 here, obtaining s = 295.

295 SUVs were sold, and 215 passenger vehicles.

find the area of a parallelogram if a base and corresponding altitude have the indicated lengths base 1 1/2 feet , altitude 6 in
Ostrovityanka [42]

The area of parallelogram is 108 square inches

<em><u>Solution:</u></em>

<em><u>The formula for area of parallelogram is:</u></em>

Area = base \times height

From given,

Base = 1\frac{1}{2}\ feet = \frac{2 \times 1 + 1}{2} = \frac{3}{2}\ feet

Height = 6\ inches

<em><u>Convert feet to inches</u></em>

1 feet = 12 inches

\frac{3}{2}\ feet = \frac{3}{2} \times 12\ inches = 18\ inches

<em><u>Therefore, area of parallelogram is:</u></em>

Area = 18 \times 6\\\\Area = 108

Thus area of parallelogram is 108 square inches
