Answer:
d
Step-by-step explanation:
inverse property of addition is going back to zero with the equation so adding 2 to negative 2 will go back to zero
Answer:
See picture and explanation below.
Step-by-step explanation:
With this information, the matrix A that you can find is the transformation matrix of T. The matrix A is useful because T(x)=Av for all v in the domain of T.
A is defined as
denotes the vector of coordinates of
respect to the basis
(we can apply this definition because
forms a basis for the domain of T).
The vector of coordinates can be computed in the following way: if
then
.
Note that we have all the required information:
then
hence
The matrix A is on the picture attached, with the multiplication A(1,1,1).
Finally, to obtain the output required at the end, use the properties of a linear transformation and the outputs given:
In this last case, we can either use the linearity of T or multiply by A.

Step-by-step explanation:
Gave up on delta math.
X + x + 10 + x + 20 + x + 30 = 84.
4x + 60 = 84.
84 − 60 = 24
4x = 24.
24 / 4 = 6 = x.

Answer:
y =
x + 7
Step-by-step explanation:
the equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
y - 8 = -
(x + 5) ← is in point- slope form
with m = - 
given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= 
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept ) , then
y =
x + c ← is the partial equation
to find c substitute (- 6, - 2 ) into the partial equation
- 2 = - 9 + c ⇒ c = - 2 + 9 = 7
y =
x + 7 ← equation of line K
