3)distributive property
Robert had given 3 to each term. which then results in 3x+6=21. Then. if he further went on, you would subtract 6 from each side giving you 15 then divide 15 by 3 giving you x=5.

What are the solutions to the equation f(x)= g(x)?
PIT_PIT [208]

Answer:

2 solutions

Step-by-step explanation:

We are given the equations of f(x) and g(x).

To find f(x) = g(x), we just let those two equations equal each other

x^{2} -4x+5=x+1

Group all like terms,

x^{2} -3x+4=0

Factorise,

(x-4)(x+1)=0

x=4, x=-1

Therefore, there are two solutions

Hope this helped!!

What is the solution to 9e-7=7e-11<br> need it now
oee [108]

The answer is e = -2

I hope this helped! If so, please mark brainliest!

Step by step solution :

Step  1  :

Pulling out like terms :

1.1     Pull out like factors :

  2e + 4  =   2 • (e + 2)  

Equation at the end of step  1  :

Step  2  :

Equations which are never true :

2.1      Solve :    2   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

2.2      Solve  :    e+2 = 0  

Subtract  2  from both sides of the equation :  

                     e = -2

Whats the vertex at of y-13=2(x+4)^2
Kipish [7]
The vertex form:
y=a(x-h)^2+k
(h,k) - the coordinates of the vertex

y-13=2(x+4)^2 \\&#10;y=2(x+4)^2+13 \\&#10;y=2(x-(-4))^2+13 \\ \\&#10;h=-4 \\ k=13

The coordinates of the vertex are (-4,13).
