Subtract 23.5 from 36.9 which gives you 13.4. The differences in temperature is therefore 13.4
Answer:
or
Step-by-step explanation:
we have
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Complete the square. Remember to balance the equation by adding the same constants to each side
Rewrite as perfect squares
The slope-intercept form: y = mx + b
m - a slope
b - a y-intercept
y = x + 3
Answer: the slope m = 1, y-intercept b = 3 -> (0; 3).
In general, √(y²) = |y|, since y can be positive or negative and y² would have the same value either way.
So,
1) if y > 0, then |y| = y, and
-15√(y²) = -15 |y| = -15y
2) if y < 0, then |y| = -y, and
-√(16y²) = -|4y| = -|4| |y| = -4 (-y) = 4y
' m > 0 ' is EVERYTHING on the number line to the right of zero.
