If f(x) = 2x2 + 3x and g(x) = x – 2, what is (f + g)(2)?

goblinko [34]

For this case we have the following functions:
$f(x) = 2x^2 + 3x

g(x) = x - 2$
The first thing we must do is calculate the sum of functions or equivalently:
$(f + g)(x) = f(x) + g(x)
$
We have then:
$(f + g)(x) = (2x^2 + 3x) + (x - 2)
$
To complete the sum, we must add the terms whose exponents are equal.
We have then:
$(f + g)(x) = 2x^2 + (3x + x) - 2

(f + g)(x) = 2x^2 + 4x - 2$
Then, we evaluate the function for x = 2:
$(f + g)(2) = 2(2)^2 + 4(2) - 2
$
Rewriting we have:
$(f + g)(2) = 2(4) + 4(2) - 2

(f + g)(2) = 8 + 8 - 2

(f + g)(2) = 14$
Answer:
$(f + g)(2) = 14
$

Y = 2x + 5 and 3x + y = 40

Sophie [7]

ANSWER: x=7, y=19

Steps

1. Substitute y=2x+5

3x+2x+5=40

2. For y=2x+5 , Substitute x=7

y=2 * 7+5

3. 2 * 7+5=19

y=19

A rectangular lawn is 65 m long and 34 m wide. Over time, people have walked along a diagonal as a shortcut and have created a s

irina [24]

To calculate the length of the diagonal, use the Pythagorean theorem:
c^2 = a^2 + b^2, where c is the diagonal.
c^2 = 65^2 + 34^2
c^2 = 4225 + 1156
c^2 = 5381
c ~ 73.36
To the nearest tenth of a meter, the diagonal has a length of 73.4 m
