Select the equation in which the graph of the line has a negative slope, and the y-intercept equals 50.
(a) 10x – 5y = 40
(b) 5x – 10y = –12
(c) 5x + y = 50
(d) x – 2y = 10

The answer that represent a negative slope and a y-intercept 50 is letter C.

Step-by-step explanation:

The answers are represented like a general equation Ax + By + C = 0, so you need to clear "y" to find slope-intercept form of a line y=mx+b, where m is the slope and b is the intercept, so if you clear:

a) y = (10x - 40)/5 in this ecuation the slope is positive and the ininterception 40 negative.

b) y = (5x +12)/10 in this ecuation the slope is positive and the interception 12 positive.

d) y= (x-10)/2 in this ecuation the slope is positive and the interception 10 negative.

c) y = 50 - 5x, in this ecuation the slope is negative, and the interception 50 positive, so this is the correct answer.

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
