what is the equation, in slope- intercept form, of the line that contains the points (-3,4) and (5,7)
gavmur [86]

Answer:

y = \frac{3}{8} x + \frac{41}{8}

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

To calculate the slope use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (- 3, 4) and (x₂, y₂ ) = (5, 7)

m = \frac{7-4}{5+3} = \frac{3}{8}, hence

y = \frac{3}{8} x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

using (5, 7 ), then

7 = \frac{15}{8} + c ⇒ c = 7 - \frac{15}{8} = \frac{41}{8}

y = \frac{3}{8} x + \frac{41}{8} ← equation in slope-intercept form

Using the function attached.<br> Find (f+G)(x)
sp2606 [1]

We have been given two functions f(x)=-8x^3+5x^2+7x+4 and g(x)=8x^3-2x+3. We are asked to find (f+g)(x).

We will use composite function property (f+g)(x)=f(x)+g(x) to solve our given problem.

(f+g)(x)=-8x^3+5x^2+7x+4+8x^3-2x+3  

Now we will combine like terms as:

(f+g)(x)=-8x^3+8x^3+5x^2+7x-2x+4+3

(f+g)(x)=5x^2+5x+7

Therefore, the value of  (f+g)(x) would be 5x^2+5x+7.
