Answer:

$2x+10 \\\\or\\\\2(x+5)$

Step-by-step explanation:

in order to write an equivalent expression to -3x+5(x+2) we need to expand it and simply (sometimes factoring):

$-3x+5(x+2) =\\\\= -3x+5x+10 \\\\=5x-3x+10\\\\=2x+10$

and we can go further :

$2x+10=2(x+5)$

Hope this helps

How to find derivative of a function at a given point?

seraphim [82]

Fill in the point values in the formula for the derivative.

____

Example

y = x^2 + 3x . . . . . we want y' at (x, y) = (1, 4)

y' = 2x +3 . . . . . . . take the derivative dy/dx of the function

Fill in the value x=1 ...

y' = 2·1 +3 = 5

The value of the derivative at (x, y) = (1, 4) is 5.

Can someone pease help

Hatshy [7]

ANSWER

$f(1) = - 34$

$f(n) = f(n - 1) + 13$

EXPLANATION

The given sequence is;

-34,-21,-8,5,....

The first term of the sequence is

$f(1) = - 34$

The common difference is

$d = 5 - - 8$

$d = 5 + 8 = 13$

The recursive definition is given by;

$f(n) = f(n - 1) + d$

$f(n) = f(n - 1) + 13$

for n=2,3,4,...

Write the equation of the line that passes through the points (−7,0) and (6,−4).

Over [174]

Answer:

y=-4/13x-28/13

Step-by-step explanation:

m=y2-y1/x2-x1

m=-4-0/6-(-7)

m=-4-0/6+7

m=-4/13

y-y1=m(x-x1)

y-0=-4/13(x-(-7))

y-0=-4/13x-28/13

y=-4/13x-28/13
