Answer:
x+y=0
Step-by-step explanation:
slope m of given equations is
(-5+1)÷(3+1)
=-1
then the equations of this line is
y-(-1)=m(x-1)
or, y+1=-1(x-1)
or, y+1= -x+1
or, x+y=0
x+y=0 is required equation of line.
x is powering both numbers so it can be outside the parenthesis.
We have given that 3^x.
<h3>
What is the expression?</h3>
An expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
The first one isn't an answer because 3^x is exponential while x^3 is a cubic function.
If you draw them you will see that they are very different.
B is correct because we can divide both numerator and denominator by 6 and we get 3^x.
C is not correct because x is not powering 3 so we cannot divide both by 6D is correct because 3^(x-1) is the same as
and when multiplied by 3 we get 3^x
3^x*3^(-1) = 3^x/3
E is not correct.
will understand after the explanation in DF is correct.
x is powering both numbers so it can be outside the parenthesis.
The question is incomplete the complete question is,
Which expressions are equivalent to the one below? Check all that apply.
3^x
A. x^3
B.(18/6)^x
C.18^x/3
D.3(3^(x-1))
E.3(3^(x+1))
F.18^x/6^x

Answer:
Hi
Step-by-step explanation:
Answer:
x = 5
Step-by-step explanation:
I already answer this on another question you actually made, but here it is again:
To do this, you need to use the Thales theorem.
You can actually apply this theorem and choose two sides of the figure to do it.In this case, I will choose segment LM and MN and look for a ratio with DE and EF like this:
LM/MN = DE/EF
This theorem states that you can stablish a ratio between two segments assuming that you have at least two paralels lines, like DL || EM || FN
Therefore, it's time to replace the values of those segments and solve for X:
LM/MN = DE/EF
14/16 = 6x -9 / 4x + 4
7/8 = 6x - 9 / 4x + 4
7(4x+4) = 8(6x-9)
28x + 28 = 48x - 72
72 + 28 = 48x - 28x
100 = 20x
x = 100/20
x = 5

Answer:
below the x-axis
Step-by-step explanation:
y=x^2+2x-3
the vertex is located on the axis of symmetry
h
to find h ax^2 +bx+c
h= -b/2a = -2/2(1) = -1
the x coordinate of the vertex is -1
to find the y coordinate, substitute into the equation
y = (-1)^2 +2(-1) -3
= 1-2-3
= -4
(-1,-4)
the vertex is below the x axis
