Answer:
x = -5
Step-by-step explanation:
The equation y = x^2+10x+25 can be factored to (x+5)^2
when (x+5)^2 = 0
x = -5
meaning the equation has a line of symmetry at x = -5
we can't find the range of a function only with its domain , we must have its graph or its equation to say anything about it , with your information we are only able to say , its range has just a member.
Answer:
B or the second option
Step-by-step explanation:
We can label the diagram parts A-E to fully represent the situation in the question.
A: Julie's ascent up the mountain (moving/increasing)
B: Julie drinking hot chocolate (stationary/constant)
C: Julie's descent down the mountain (moving/decreasing)
D: Julie rests (stationary/constant)
E: Julie's final descent down the mountain (moving/decreasing)
11 hours. The temp. decreases with time at a 2:1 ratio receptively <span />
Ok so,
Simplifying
4x + 4y + 4z + 4 = 0
Reorder the terms:
4 + 4x + 4y + 4z = 0
Solving
4 + 4x + 4y + 4z = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4' to each side of the equation.
4 + 4x + 4y + -4 + 4z = 0 + -4
Reorder the terms:
4 + -4 + 4x + 4y + 4z = 0 + -4
Combine like terms: 4 + -4 = 0
0 + 4x + 4y + 4z = 0 + -4
4x + 4y + 4z = 0 + -4
Combine like terms: 0 + -4 = -4
4x + 4y + 4z = -4
Add '-4y' to each side of the equation.
4x + 4y + -4y + 4z = -4 + -4y
Combine like terms: 4y + -4y = 0
4x + 0 + 4z = -4 + -4y
4x + 4z = -4 + -4y
Add '-4z' to each side of the equation.
4x + 4z + -4z = -4 + -4y + -4z
Combine like terms: 4z + -4z = 0
4x + 0 = -4 + -4y + -4z
4x = -4 + -4y + -4z
Divide each side by '4'.
x = -1 + -1y + -1z
Simplifying
x = -1 + -1y + -1z
