1) the standar form of the equation is ax+by = c, therefore, for y = -2/3x+5, multiply by 3 the previous equation, and its result is 3y = -2x+15⇒ 3y +2x = 15

the final result is 2x+3y = 15

Which of the following is the equation of a line parallel to the line y=-x+1 passing through the point (4,1)

Softa [21]

Y=-x+b

plug in x = 4 and y = 1 to find b

1 = -4 + b and we know that if you add 5 and -4 you get 1. So ...

5 = b so if we plug that in

y= -x + 5

which is the same as y + x = 5, So it would be A

Suppose that an urn contains 3 black marbles, 7 yellow marbles, and 10 green marbles. If one marble is selected, determine the p

Yuliya22 [10]

Answer:

1/2

Step-by-step explanation:

Simple probability is a ratio of the number of ways the thing we want to happen can to the total possible outcomes.

(For example, we flip a coin and want heads, but it can land on heads or tails. Our probability of getting heads is 1/2, one way to get heads over the 2 possible outcomes)

So for this problem, there's 20 possible things that CAN happen (3 + 7 + 10) and 10 ways we get what we want (a green marble).

Our probability of getting a green marble is $\frac{10}{20\\}$ , which simplifies to $\frac{1}{2}$
