Subtract 4x form both sides:-

-24y = -4x - 2
Divide both sides by -24:-

y =1/6 x  + 1/12

If two of the four expressions x + y, x + 5y, x – y, and 5x – y are chosen at random, what is the probability that their product
storchak [24]

Answer:

  1/6

Step-by-step explanation:

The product will only be of the required form if the two chosen factors are of the form (x +by) and (x -by).

For the factor (x+y), there is also a factor (x-y) on the list. For the factor (x+5y), there is no factor (x-5y) available.

So, of the (4·3)/2 = 6 possible ways to choose two expressions from the four given expressions, only one pair of the 6 will have a product of the required form.

The probability is 1/6.

Which of the following is the equation of a line perpendicular to the line y=-10×+1 passing through the point (5,7)
Juliette [100K]
Y = -10x + 1...slope here is -10. A perpendicular line will have a negative reciprocal slope. To find the negative reciprocal of a number, flip the number and change the sign. So our perpendicular line will need a slope of 1/10.

y = mx + b
slope(m) = 1/10
(5,7)....x = 5 and y = 7
now sub and find b, the y int
7 = 1/10(5) + b
7 = 1/2 + b
7 - 1/2 = b
14/2 - 1/2 = b
13/2 = b

so ur perpendicular line going thru (5,7) is y = 1/10x + 13/2

Five cards are selected without replacement from a pack of 52 playing cards. What is the probability of exactly 3 hearts?
irga5000 [103]
There are 13 total hearts in the deck, which leaves 39 non-hearts. You're drawing a hand of five cards, so the probability of getting exactly 3 hearts is

\dfrac{\binom{13}3\binom{39}2}{\binom{52}5}=\dfrac{2717}{33320}

as required.

A taxi company charges passengers $2.00 for a ride, no matter how long the ride is, and an additional $0.20 for each mile travel
choli [55]

m=miles

cost for 1 mile ride= $2.20

c=cost

rule  c=0.20m+2.00

c=0.20x1+2

c=0.20+2

c+2.20

5u exponent 7 - 21u exponent 7<br><br> Simply
bagirrra123 [75]
Assuming the given is: 5u^7 - 21u^7
Since both algebraic terms are identical (both are using u^7), we can subtract the coefficients directly, as in: 5 - 21 = -16
Therefore, 5u^7 - 21u^7 = -16u^7
