Answer:

Mark spent 13 dollars on supplies for the dance. His goal is to make 20 dollars. How much worth of tickets does he need to sell to make his goal.

Step-by-step explanation:

To find this, we know we need to subtract 13 from something, in this case ticket sales. That number must be larger than 20, which in this case is the profits.

W (n) = n^2-n find w (-3)

Papessa [141]

Answer:

$w(-3) = 12$

Step-by-step explanation:

Plug in -3 for n in the equation:

$w(n) = n^2 - n$

$w(-3) = (-3)^{2} - (-3)$

Simplify. Remember to follow PEMDAS. First, solve the power:

$w (-3) = (-3)^2 - (-3)\\w (-3) = (-3 * -3) - (-3)\\w (-3) = (9) - (-3)$

Next, combine like terms. Note that if there are two negative signs directly next to each other, it becomes a positive sign. Add:

$w(-3) = 9 - (-3)\\w(-3) = 9 + 3\\w(-3) = 12$

Your answer: $w(-3) = 12$

A city planner is rerouting traffic in order to work on a stretch of road. The equation of the path of the old route can be desc

Alborosie

Answer:

The correct option is;

y - P = two fifths (x - Q).

Step-by-step explanation:

The equation for the old route is given as follows;

$y = \dfrac{2}{5} \cdot x - 4$

Therefore, we have;

The slope of the equation of the old route = 2/5

Given that the new route is parallel to the old route and passes through the point (Q, P), the slope of the new route = 2/5 and the equation of the new route in slope and intercept form can be written as follows;

y - P = 2/5×(x - Q)

Therefore, the correct option is y - P = two fifths (x - Q).
