Sveta_85 [38]

Answer:

0, -1, -3

Step-by-step explanation:

f(x) = y = height of the line plotted

if you treat the x axis as the "ground" or "floor"....you're looking for the point when the graph "hits" the "floor", meaning zero height.

Let C represent the cost in dollars and R represent the revenue in dollars. What is the break-even point? Use a table to help if
krek1111 [17]

Answer:

(5,225)

Step-by-step explanation:

The break even point is when the cost equals the revenue.

C=R

15x+150=45x

150=30x

x=5

Plug this back into the original equations to get the y value.

15*5+150=225

or 45*5=225

Please help will give brainliest
beks73 [17]

Answer:

4

Step-by-step explanation:

The sum of the measures of all interior angles in triangle is always equal to 180°. So,

∠A+∠B+∠C=180°

∠B=180°-63°-49°=68°

Now use the sine rule:

\dfrac{c}{\sin \angle C}=\dfrac{b}{\sin \angle B}\\ \\\dfrac{3}{\sin 49^{\circ}}=\dfrac{b}{\sin 68^{\circ}}\\ \\b=\dfrac{3\sin 68^{\circ}}{\sin 49^{\circ}}\approx 3.685\approx 4
