Answer:
23
Step-by-step explanation:
Learn this...it really helps
VUX : vertical line, undefined slope, represented by x = a number
HOY : horizontal line, 0 slope, represented by y = a number
so we need an undefined slope.....that means it is a vertical line.....it is represented by x = a number......and that number is the one in the x position...so ur equation is : x = 4 (because (4,7)...the x digit is 4
P=35
Simplifying
p + -1(5)(-3) = -20
Multiply -1 * 5
p + -5 * -3 = -20
Multiply -5 * -3
p + 15 = -20
Reorder the terms:
15 + p = -20
Solving
15 + p = -20
Solving for variable 'p'.
