Group up the like terms and combine them
2x^2 and -7x^2 add up to -5x^2
6x and 2x add up to 8x
1 and -3 add up to -2
We end up with -5x^2 + 8x - 2
<h3>Answer: Choice B</h3>
We can find out he answer to the question by using the information given.
Since we know that Death Valley is the lower of the two spots, we can assume that we can add the difference in elevation to Death Valley to get the elevation of Mt Whitney.
-86+4,504=4,418
Th elevation of Mt Whitney is 4,418 meters above ground.
Hope this helps!
ANSWER
The correct answer is
.
<u>EXPLANATION</u>
We were given the matrix equation;
.
We must first simplify the Left Hand Side of the equation by adding corresponding entries.
.
That is;
.
Since the two matrices are equal, their corresponding entries are also equal. we equate corresponding entries and solve for m and n.
This implies that;

We got this equation from row one-column one entry of both matrices.

Also, the row three-column three entries of both matrices will give us the equation;


Hence the correct answer is
.
The correct option is option 2
V-10=-3
add 10 by both sides (opposite of -10)
v= 7
-2x^2 + 8 because if you turn it into vertex form and determine
