Find the equation of the graphed line.?

kiruha [24]

Answer:

c. y = x - 6.

Step-by-step explanation:

It's a straight line whose general form is y = mx + c.

The slope is (0, -6) / (6, 0)

= -6 / -6

= 1 so the coefficient of x , (m) is 1.

The value of c ( the y-intercept) is -6.

At a particular restaurant, each pizza roll has 60 calories and each mini hotdog has 70 calories. A combination meal with pizza

PolarNik [594]

Answer:

There are 9 pizza rolls and 12 mini hotdogs in the meal.

Step-by-step explanation:

We are given the following in the question.

Let x be the number of pizza rolls sold and y be the number of mini hotdogs in the combination meal.

Total number of items in combination meal = 21

Thus, we can write the equation:

$x + y = 21$

Calorie in a pizza roll = 60

Calorie in a mini hotdog = 70

Total calories = 1380

Thus, we can write the equation:

$60x + 70y = 1380$

Solving the two equations, we get,

$60x + 70y - (60x+60y) = 1380 - 60(21) \\10y = 120\\\Rightarrow y = 12\\\Rightarrow x = 21-12 = 9$

Thus, there are 9 pizza rolls and 12 mini hotdogs in the meal.

The tree diagram represents an experiment consisting of two trials.

Sladkaya [172]

Answer:

P(D) = 0.65

Step-by-step explanation:

it's like following a path on map

each line is like a street length

First, it's 0.5 to A and then 0.6 to D.

Then, it's 0.5 to B and 0.7 to D.

P(D) = (0.5 times 0.6) + (0.5 times 0.7) =

P(D) = 0.30 + 0.35 = 0.65

A tree diagram is simply a way of representing a sequence of events.

Tree diagrams are particularly useful in probability since they record all possible outcomes in a clear and uncomplicated manner.
