x + 100 = 180
x = 80
Answer:
1)D
Step-by-step explanation:
The box method or latitude or longitude.
Factor
=(2x - 3)(2x + 5)
roots (zero)
2x - 3 = 0
2x = 3
x = 3/2
x = 1.5
2x + 5 = 0
2x = -5
x = -5/2
x = -2.5
Answer:
your question is really not clear but if you were to put the -4 in the Y then the answer would be X=1/3, if you plug in -4 for X and find Y then Y = -17
Step-by-step explanation:
plug in -4 in Y
-4=3x-5 add 5 on both sides,
1 = 3x divide 3 on both sides
1/3= x
plug in -4 in X
y = 3(-4)-5 multiply 3 and -4 = -12
y = -12-5 subtract the -12 and -5 = -17
y = -17
