Answer:

Step-by-step explanation:

hello :

the point-slope formula is :  

y - y_1 = m(x - x_1) the point is A(x_1 , y_1 ) , m : the slope

in this exercice :  x_1 = -1            y_1 = 4             m = 3 

so : y - 4 = 3(x +1)   ...an equation for this line .

One serving of trail mix has 67 grams of carbohydrates, which is 22% of the recommended daily amount. What is the total recommen
DaniilM [7]

For this case we propose a rule of three:

67 grams -----------> 22%

x grams --------------> 100%

Where:

The variable "x" represents the recommended amount of daily carbohydrates.

So, we have:

x = \frac {100 * 67} {22}\\x = 304.5455

Rounding we have the recommended amount, in grams, of carbohydrates: 305 grams

Answer:

305 grams

The graph below shows the total cost for lunch, c, when Will and his friends buy a large salad to share and several slices of pi
Helga [31]

Answer:

2.50 dollars.

Step-by-step explanation:

Given:

Will and his friends buy a large salad to share and several slices of pizza, p.

The graph given shows the total cost for lunch, c and slices of pizza,p.

p is marked horizontally, and c vertically.

Observing the points marked we find that for every increase of one slice of pizza, the cost i.e. c on vertical line increases by 0.50 times vertical grid.

Since each grid equals 5 dollars vertically, we find 1/2 grid increase is equal to increase of 1/2(5 ) =2.50 dollars.

Thus for increase of one slice of pizza, 2.50 dollars cost is increased.

8th Grade Functions: Bike Race
Arturiano [62]

Answer:

Juan wins the race

Step-by-step explanation:

<u>The graph is shown in attached image.</u>

<u />

The black line is Juan's graph.

The green line is Antonio's graph.

The graph shows the distance (y-axis) with time (x-axis).

The end of the curve(s) means the end of the race. Both curve's ending point in y-axis is 4 miles so the end of the race is 4 miles.

But in x-axis, we see the time:

Juan finishes at 13 minutes

Antonio finishes at 15 minutes

<u>Definitely Juan wins the race</u>
