2 degrees drop every hour, so 6 * 2 = 12
So, it would drop by 12 degrees after 6 hours.
Answer:
D. y = -1/4x + 3
Step-by-step explanation:
If the line is perpendicular, it will have a opposite reciprocal slope.
So, the slope will be -1/4.
Plug in this slope and the given point into y = mx + b, and solve for b:
y = mx + b
-6 = -1/4(12) + b
-6 = -3 + b
-3 = b
Plug in the slope and y intercept into y = mx + b
y = -1/4x - 3
So, the correct answer is D. y = -1/4x + 3
Answer:
The correct option is (1).
Step-by-step explanation:
The given system of equation is,
..... (1)
.... (2)
The solution of the system of equation is the point where both line intersect each other.
Solve the equation by method of elimination.
Multiply equation 1 by 3.
... (3)
Add equation (2) and (3).




Put this value in equation 1.



Therefore, the lines intersect each other at (0.25,3.75). So, the first option is correct.
