Objective: Solve 2x + 3 = 5x - 42 for x.
Step 1: Subtract 3 from both sides.
2x + 3 = 5x - 42
2x = 5x - 45
Step 2: Subtract 5x from both sides.
2x = 5x - 45
-3x = -45
Step 4: Divide both sides by -3.
-3x = -45
x = 15
Answer:
x = 15
I used the Pythagorean formula, which is a² + b² = c².
a² and b² are the two side legs while c² is the hypotenuse.
One of the side is 42 - 8 = 34 cm.

Not necessarily, the more correct definition is opposite reciprocal slopes.
The example used is how horizontal and vertical lines are parallel. Horizontal lines have a slope of 0, also written as 0/1. However, vertical lines have an undefined slope, which isn't necessarily negative. It has a slope of 1/0, which is undefined. In this case, the reciprocal isn't negative.
In all other cases (1 and -1, 2 and -1/2, etc.) yes, the perpendicular pairs are negative and reciprocal.
Answer:
A
Step-by-step explanation:
A linear function describes a straight line with constant gradient. Hence A is the answer as it has a constant gradient of -1 .
B is wrong as the graph has an undefined gradient.
C is wrong as it has an increasing gradient.
D is wrong as it does not have a constant gradient too.
