Mathematics
1 answer:
GuDViN [60]3 years ago
5 0

Step-by-step explanation:

y = y

x - 2 = 2x - 3 - 3x²

3x² + x - 2x = - 3 + 2

3x² - x = - 1

.

a = 3, b = -1, c = 0

.

\sf{x = \frac{-b \pm \sqrt{b^{2} - 4ac} }{2a} }

\sf{x = \frac{- (-1) \pm \sqrt{-1^{2} - 4 (0)} }{2(3)} }

\sf{x = \frac{ 1 \pm \sqrt{1 - 0} }{6} }

\sf{x = \frac{ 1 \pm \sqrt{1} }{6} }

\sf{x = \frac{ 1 + 1 }{6} }

\sf{x = \frac{ 2 }{6} }

\sf{x = \frac{ 1 }{3} }

.

Substitution :

y = x - 2

y = ⅓ - 2

y = ⅓ - 6/3

y = - 5/3

y = - 1 ⅔

Lawrence sells 40% of the apples on his cart, and are left with 420 apples. How many apples had Lawrence started with?
lutik1710 [3]

Answer:

700 apples

Step-by-step explanation:

Let

x = Total number of apples in the cart

Percentage of apples sold = 40%

Number of apples sold = Percentage of apples sold * Total number of apples in the cart

= 40% * x

= 0.4 * x

= 0.4x

Number of apples left in the cart = 420

Total number of apples in the cart = Number of apples sold + Number of apples left in the cart

x = 0.4x + 420

x - 0.4x = 420

0.6x = 420

x = 420/0.6

x = 700

x = Total number of apples in the cart = 700

Make sure it is the correct answer!!!!!!!!!
s344n2d4d5 [400]

For this case we have by definition, if "y" varies directly with "x", then it is true that:

y = kx

Where:

k: It is the constant of proportionality

We have the following equation:

y = 2.5x

So, as mentioned above we have to:

k = 2.5

Answer:

k = 2.5
