What is the solution to the following system of equations? -5x-4y=-4 25x+20y=20

Tju [1.3M]

Simplify
2nd one divide both sides by 5
5x+4y=4
hmm, seems familliar
times it by -1
-5x-4y=-4
same as other one

they are the same line
therefor the solution set is all the points on the line -5x-4y=-4 or y=(-5/4)x+1

solution set is alll points on y=(-5/4)x+1 or 5x+4y=4

Eva is picking fruit at a farm. The fees are $5 for entry to the farm, $2.50 per pound of blueberries, and $2 per pound of apple

olasank [31]

Answer:

The required expression is: $y = 5 + 2.50b + 2a$

Step-by-step explanation:

Given

$Entry = \$5$

$Blueberry = \$2.50$

$Apple = \$2$

Required

Write an expression for this scenario

If 1 pound of blueberry cost $2.50

then b pounds = 2.50 * b

If 1 pound of apple cost $2

then a pounds = 2 * a

The required expression (y) is then calculated as

$y = Entry\ Fee + Blueberry = Apple$

$y = 5 + 2.50 * b + 2 * a$

$y = 5 + 2.50b + 2a$

Hence, the required expression is: $y = 5 + 2.50b + 2a$

What is the probability of drawing the compliment of a king or a

inna [77]

Answer:

The probability of drawing the compliment of a king or a queen from a standard deck of playing cards = 0.846

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Let 'S' be the sample space associated with the drawing of a card

n (S) = 52C₁ = 52

Let E₁ be the event of the card drawn being a king

$n( E_{1} ) = 4 _{C_{1} } = 4$

Let E₂ be the event of the card drawn being a queen

$n( E_{2} ) = 4 _{C_{1} } = 4$

But E₁ and E₂ are mutually exclusive events

since E₁ U E₂ is the event of drawing a king or a queen

<u><em>step(ii):-</em></u>

The probability of drawing of a king or a queen from a standard deck of playing cards

P( E₁ U E₂ ) = P(E₁) +P(E₂)

$= \frac{4}{52} + \frac{4}{52}$

P( E₁ U E₂ ) = $\frac{8}{52}$

<u><em>step(iii):-</em></u>

The probability of drawing the compliment of a king or a queen from a standard deck of playing cards

$P(E_{1}UE_{2}) ^{-} = 1- P(E_{1} U E_{2} )$

$P(E_{1}UE_{2}) ^{-} = 1- \frac{8}{52}$

$P(E_{1}UE_{2}) ^{-} = \frac{52-8}{52} = \frac{44}{52} = 0.846$

<u><em>Conclusion</em></u>:-

The probability of drawing the compliment of a king or a queen from a standard deck of playing cards = 0.846

Nastasia [14]

Answer:

The height of the building is 730 feet.

Step-by-step explanation:

370 x 12 = 4,440 inches

4,440 ÷ 18.5 = 240 inches

240 x 36.5 = 8,760 inches = 730 feet
