Complete the equation of the line through (6,-6) and (8,8). Use exact numbers. y=?

MariettaO [177]

Y = 7x - 48

use slope formula so, y2 - y1 over x2 - x1 to get your m value or your slope which is 7. then plug in the slope and a random set of point so I used (6, -6). -6 = 6(7) + b, simplify.
-6 = 42 + b, subtract 42 which leaves you with b= -48. hope this helps :)

Consider an urn with 7 black balls, 3 yellow balls, and 4 orange balls. If 3 balls are chosen randomly with replacement, what is

KATRIN_1 [288]

Answer:

1.79% chance or $\frac{6}{343}$

Step-by-step explanation:

7+3+4=14

chance of yellow $\frac{3}{14}$

chance of orange $\frac{4}{14}$

$\frac{3}{14} * \frac{4}{14} *\frac{4}{14} = \frac{6}{343}$

Translate to an algebraic statement. "The quotient of twice a number and 7 is 20."

Genrish500 [490]

Answer:

Translation: 2x/7 = 20

Step-by-step explanation:

When we listen to the word "quotient", it means the solution to a division problem.
An unknown number that has been multiplied by 2 is in the numerator because it came before the 7 in the statement.
The number "7" is in the denominator because it came after the 2x in the statement.
The word "is" represents an equal sign.
The solution to the division problem (quotient) is 20.

If we put these clues together, we get 2x/7 = 20 as our translated equation.

Hence, our algebraic statement is 2x/7 = 20. The key is to listen to the statement.
