You must get your answer and when you get your answer, you factor them.
The perpendicular line to "Y = -4x + 10" that goes the the point (4,-6) is Y = 1/4x + 5.
The slopes are usually a fraction and a whole number. If the first slope is a whole number, it changes to a fraction, and vice versa. Also, if the first slope is negative, the perpendicular slope is positive and vice versa.
The y intercepts in this case are 10 (first slope) and 5 (dividing by 2) since it has to go through (4,-6). See graph below.
I hope this helps!
Answer: C) 25
Step-by-step explanation:
x²+10x+ __=16+ __
Only the square of 5, 5², which is 25, can make the two factors plus equal to 10x, so we need to add 25.
Answer: X = 19
Step-by-step explanation: it is a three equation system, the problem is you don't have the third equation, so we have to infer it, and it's: PRQ + QRS = 180.
then we do as follows:
