Answer:

0.75.

Step-by-step explanation:

Sum to infinity =  1 / (1 - (-1/3))

= 1 / 4/3

= 3/4

= 0.75.

6x+Q=Px+15 what values of P and Q result in an equation with exactly one solution?
NNADVOKAT [17]

P = 6

Q = 15

Note the equal sign. This means that both expression's out come must equal each other. For that to happen, everything inside both expressions must equal each other. In this case:

6x + Q = Px + 15; 6x + 15 = 6x + 15

Which of the following best describes the slope of the line below? A. Zero B. Undefined C. Positive D. Negative
nadya68 [22]

Answer:

D. negative

Step-by-step explanation:

Let's analyze each answer choice.

A. Zero

A line with a zero slope is a horizontal line. The x values change, but the y values stay the same.

B. Undefined

A line with an undefined slope is a vertical line. The x values don't change and the y values vary.

C. Positive

When a line has a positive slope, the line increases from left to right.

D. Negative

When a line has a negative slope, the line decreases from left to right.

When we move from left to right on the graph, the line moves down. Therefore, this line must have a negative slope and D is correct.
