Answer:

(f+g)(x)=3x^2+15x-3

Step-by-step explanation:

f(x) = 3x^2+10x\\g(x) = 5x-3

Adding both

(f+g)(x) = 3x^2+10x+5x-3

(f+g)(x)=3x^2+15x-3

Answer:

3x^2 +15x -3

Step-by-step explanation:

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

(f +g)(x)= 3x^2 + 10x + 5x -3

= 3x^2 +15x -3

EXPLANAT

Given:

14 foot tree

8foot shadow

4foot shadow

Let h be the height of a tee that casts a 4 foot long shadow.

Using proportion;

14 foot = 8 ft shadow

h = 4 ft shadow

Cross - multiply

8h = 56

Divide both-side by 8

h = 7 foot.

What is the equation of the given line in the point-slope form
Genrish500 [490]
First using the given two points we can find the slope (m) of the line

Slope = m =  \frac{Rise}{Run} \\  \\ 
m= \frac{4-1}{3-0} \\  \\ 
m=1

Thus the slope of given line is 1.

Using slope and a point (0,1) we can write the equation in point slope form as

y - 1= 1(x-0)
y - 1 = x

The above equation is the point-slope form of the equation.
