Answer:

  • x - 4y = 22

Step-by-step explanation:

<u>Given line:</u>

  • x - 4y = 20

<u>Convert the equation into slope-intercept form:</u>

  • x - 4y = 20
  • 4y = x - 20
  • y = 1/4x - 5

It has a slope of 1/4.

Parallel lines have equal slopes.

<u>Find the parallel line lines that passes through the point (2, - 5):</u>

  • y = 1/4x + b

<u>Substitute x and y values to work out the value of b:</u>

  • - 5 = 1/4*2 + b
  • - 5 = 1/2 + b
  • b = - 5 - 1/2
  • b = - 11/2

<u>The line is:</u>

  • y = 1/4x - 11/2

<u>Covert this into standard form:</u>

  • y = 1/4x - 11/2
  • 4y = x - 22
  • x - 4y = 22

  • x-4y=20

Isolate y

\\ \sf\longmapsto x-20=4y

\\ \sf\longmapsto y=\dfrac{1}{4}x-5

  • m=1/4
  • Parallel lines have equal slope

Equation of line in point slope form

\\ \sf\longmapsto y-y_1=m(x-x_1)

\\ \sf\longmapsto y+5=1/4(x-2)

\\ \sf\longmapsto 4y+20=x-2

\\ \sf\longmapsto x-4y+22=0

Answer:

Correct answer is B.

Step-by-step explanation:

Amount deducted for social security = 6.2 % annually

Amount deducted for medicare tax = 1.45 % annually

Total deduction = 6.2 +1 .45 = 7.65 %

Tax on given amount = 7.65 * 37890 = 2898.59

Therefore amount deducted annually will be $2898.59/-

Challenge fr y'all. solve this to get 50 points and brainliest coming up if you get the right answer
TEA [102]

Answer:

  • See below

Step-by-step explanation:

a)

i)

<u>Use the law of cosines:</u>

  • AB=\sqrt{PA^2+PB^2-2*PA*PB*cosP}
  • AB=\sqrt{60^2+100^2-2*60*100*cos80} =\sqrt{11516.22} =107.31

ii)

<u>Use the law of sines:</u>

  • sin ∠A / PB = sin ∠P / AB
  • sin ∠A / 100 = sin 80 / 107.31
  • sin ∠A = 100 sin 80 deg / 107.31
  • sin ∠A = 0.92
  • ∠A = arcsin 0.92
  • ∠A = 67° (rounded)

iii)

<u>Bearing of B from A:</u>

  • 90° + (67° - 30°) =
  • 127°

b)

<u>PB is longer distance. Time to reach B:</u>

  • t = d/s
  • t = 100/20 = 5 hours

<u>The speed s of the slower ship:</u>

  • s = d/t
  • s = 60/5 = 12 km/h

Elenna [48]
Write as a function equation: where f(x) is the same as "y"

f(x) = 5 + 1x   ------  y = 1x + 5

Use:  y = mx + b  (Where m = slope and b is y intercept)

Slope is 1 and y intercept is +5 

Remember slope is rise over run so 1 can be written as 1 / 1 and interpreted as rise 1 and run 1 both in the positive direction.
