Answer:
Step-by-step explanation: B26
So we are trying to solve for x so in order to do that we need to get x by itself on one side of the equal sign
first we are going to combine like terms on each side of the equal side
so on the left side we see 4+9 these are booth whole numbers not attached to a variable so we can simplify this by adding these two values together making our equation: x/13 = 12
our x is still not by itself so in order to get it by itself we need to get rid of that 13
we need that x is being divided by 13 so in order to get rid a divided value we have to do the opposite to both sides - multiply by 13 on each side!
x/13 x 13 = x
12 x 13 = 156
so our equation is now:
x = 156
is our x by itself on one side of the equal sign? yes! so our x value is 156
Answer:
6x
Step-by-step explanation:
Given that a function f(x) is given as
A) 
Now divide by delta x
B) When delta x tends to 0, this becomes
(NOte: This is the derivative of f(x))
Answer:
y - 3= 2(x - 0)
Step-by-step explanation:
hello :
note 1 :
the point-slope formula is :
y - y_1 = m(x - x_1) the point is A(x_1 , y_1 ) , m : the slope
note 2 :
the slope is : m = (y_2 - y_1)/(x_2 -x_1) when given two points :
A(x_1 , y_1 ) and B(x_2 , y_2 )
in this exercice : x_1 =0 y_1 =3 x_2 =1 y_2 =1
calculate now m = (1 - 3)/(1 -0) =-2
an equation in point-slope form is : y - y_1 = m(x - x_1)
y - 3= 2(x - 0)
