Answer:

F. $\displaystyle (2, 6)$

C. $\displaystyle (-1, 0)$

B. $\displaystyle (-2, -2)$

Step-by-step explanation:

You first need to find the linear equation [in Slope-Intercept Form of course] of this graph, which is $\displaystyle y = 2x + 2.$ To do this, starting from the y-intercept of $\displaystyle (0, 2),$ you do $\displaystyle \frac{rise}{run}$ by either moving two blocks south over one block way or two blocks north over one block east [west and south are negatives]. This will give you your rate of change [slope] of 2.

* $\displaystyle y = mx + b → Slope-Intercept Formula$

The rate of change in the temperature T of coffee at time t is proportional to the difference between the temperature M of the a

Anna11 [10]

Answer:

$T'(t)=k(M(t)-T(t))$

Step-by-step explanation:

The rate of change in the temperature T of coffee at time t is written as $T'(t)$ (remember derivatives are used to express rates of change, and in our case the rate of change of the temperature T). The difference between the temperature M of the air at time t, and the temperature T of the coffee at time t can be expressed as $M(t)-T(t)$

Saying that the rate of change in the temperature T is proportional to the difference between M and T is just a way of saying that the rate of change in the temperature T is equal to the difference between M and T, multiplied by some constant k (whose value we don't know, but still that's what it means).

Therefore we get

$T'(t)=k(M(t)-T(t))$

A group of 48 senior citizens attended a baseball game. The number of women in attendance was 12 more than the number of men. Ho

Sergio [31]

Answer:

18 men attended the baseball game, and 30 women attended the baseball game.

Step-by-step explanation:

Let the number of men in attendance be x and the number of women in attendance be x+12.

No. of men + No. of women = 48

x + x + 12 = 48

2x + 12 = 48

2x = 48 - 12

= 36

x = 36 ÷ 2

x = 18

x+12: 18 + 12 = 30
