Answer: Yes, it is A!

Step-by-step explanation:

it is a because, you can have 30 baseball cards, and six packages, so imagine this has six bags full of a certain amount of candy, and there is 30 pieces of candy, and do you want to separate them into an even amount, so this would be 30÷6= ? The? Would be 5 as in to say The constant of proportionality would also be 5.

Answer:

Option A is the correct answer.

Explanation:

 There are 6 packages that store 30 baseball cards.

  Number of cards in 1 package = 30/6 = 5

  Let us consider a as number of packages and b as number of cards.

  We have equation for number of cards,

                      b = 5 a

          The constant of proportionality = 5

Option A is the correct answer.

A zero in front of the x would make this a difference of two perfect squares. All of the other option would interfere by adding another term.

What are the solutions of the quadratic equation 4x2 - 8x – 12 = 0?
Juliette [100K]

Answer:

see bottom

Step-by-step explanation:

divide through by 4

x2 - 2x - 3 = 0

x2 - 3x + x - 3 = 0

(x2 - 3x) + (x - 3) = 0

x(x - 3) + 1(x - 3) = 0

(x + 1) (x - 3) = 0

x + 1 = 0 and x - 3 = 0

x = -1 and x = 3

7. Find an equation of the line containing (- 4,5) and perpendicular to the line 5x - 3y = 4.
bagirrra123 [75]

The equation of the line containing (- 4,5) and perpendicular to the line 5x - 3y = 4 is y = -3 / 5 x + 13 / 5

<h3>How to find the equation of a line?</h3>

The equation of a line can be represented as follows:

y = mx + b

where

  • m = slope
  • b = y-intercept

Therefore, the equation passes through (-4, 5) and perpendicular to 5x - 3y = 4

Hence,

perpendicular lines follows the rule below:

m₁m₂ = -1

Hence,

5x - 3y = 4

5x - 4 = 3y

y = 5/ 3 x - 4 / 3

m₁ = 5 / 3

5/3 m₂ = -1

m₂ = - 3 / 5

Hence,

using (-4, 5)

5 = - 3 / 5 (-4) + b

5 = 12 / 5 + b

b = 5 - 12 / 5 = 25 - 12 /5 = 13 / 5

Therefore,

y = -3 / 5 x + 13 / 5
