Take the sqrt of both sides of <span>(x+2)^2=10:
x+2 = plus or minus sqrt(10)
Solve for x: x = -2 plus or minus sqrt(10)
Evaluate x: x = -2 + sqrt(10) AND x = -2 - sqrt(10) (answers)

Step-by-step explanation:
where the letter D is the diagonal matrix with diagonal entries λ1,…,λn. Now let's assume V is invertible, that is, this particular given eigenvectors are linearly independent, you get M=VDV−1.
Kindly check the attached image below to see the step by step explanation to the question above.
Answer:
$26 + X = $57
$26 + $31 = $57
X = $31
My first time ever answering a question hope it helped =) (And sry it took long)
Step-by-step explanation:
For this case we have that by definition, the line equation of the slope-intersection form is given by:
Where:
m: It's the slope
b: It is the cut-off point with the y axis
According to the statement we have:
Thus, the equation is of the form:
We substitute the given point and find "b":
Finally, the equation is of the form:
Answer:
Answer:
first option
Step-by-step explanation:
There is a common ratio r between consecutive terms in the sequence, that is
r = - 15 ÷ 3 = 75 ÷ - 15 = - 375 ÷ 75 = - 5
The recursive formula allows a term in the sequence to be found by multiplying the previous term by r , thus
f(n) = - 5f(n - 1) if n > 1
with f(1) = 3 ← first term
