Solve system of equations with 3 variables 3x - y + 4z = 15
5x + 4y + 3z = 25
x + 3y - 2z = 5
please show steps

the answer is a i belaeve atleast thats what my calculator just gfave me

step-by-step explanation:

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
