3x - 2y = 7
-2y = -3x + 7
y = 3/2x - 7/2....slope of this line is 3/2. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign. So the slope we need is -2/3 (see how I flipped the slope and changed the sign)
y = mx + b
slope(m) = -2/3
(-3,-2).....x = -3 and y = -2
now we sub and find b, the y int
-2 = -2/3(-3) = b
-2 = 2 + b
-2 - 2 = b
-4 = b
so ur perpendicular equation is : y = -2/3x - 4 <==
The answer is 3.075.
If you divide 12.30 4 you'll get 3.075.
Answer:
Proton
Step-by-step explanation:
However, the atom itself is not the smallest known particle, but instead each atom is made up of three individual parts: electrons, protons and neutrons. Furthermore, protons and neutrons themselves are made up of even smaller parts called quarks.
Answer:
Mrs Mamie will arrive at her destination on time !
Step-by-step explanation:
Mrs Mamie drives 130miles in 2 hours that means 65 miles/h
During 7 hours she travels 65*7=455 miles that definetely is more than 390 miles as necessary.
SO YES, Mrs Mamie will arrive at her destination on time !
