Answer:
y=
3x/8x+2
Step-by-step explanation:
1
2x
−
3
4y
=−2
Step 1: Multiply both sides by 4xy.
−3x+2y=−8xy
Step 2: Add 8xy to both sides.
−3x+2y+8xy=−8xy+8xy
8xy−3x+2y=0
Step 3: Add 3x to both sides.
8xy−3x+2y+3x=0+3x
8xy+2y=3x
Step 4: Factor out variable y.
y(8x+2)=3x
Step 5: Divide both sides by 8x+2.
y(8x+2)
8x+2
=
3x
8x+2
y=
3x
8x+2
Answer:
y=
3x/8x+2
Answer:
mid point of AB (0.5 , 0)
Step-by-step explanation:
2x + 5y = 1 2x = 1 - 5y
y = 2xy+ 5 = (1 - 5y)*y + 5 = y - 5y² + 5
y-y = y - 5y² + 5 - y = - 5y² + 5
0 = - 5y² + 5
5y² = 5
y² = 1
y = 1 or y = -1
if y = 1 x = 1/2 (1 - 5) = -2 .... point A (-2 , 1)
if y = -1 x = 1/2 (1 + 5) = 3 ..... point B (3 , -1)
mid point of AB (x' , y') : x' = 1/2 (x₁ + x₂) = 1/2 (-2 + 3) = 1/2
y' = 1/2 (y₁ + y₂) = 1/2 (-1 + 1) = 0
Ph will be equal to the sum of pn and nh. Thus:
ph = pn + nh
17 = pn + 12
pn = 5
nh = pn + hm
12 = 5 + hm
hm = 8 inches
Answer:
All but A are repeating... did the question ask which is NOT a repeating decimal?
Step-by-step explanation:
Three hours because one third in an hour and there are three thirds to make one whole job so it is 3 hours
