Answer:

D or y = 1/2x - 4

Step-by-step explanation:

The slope-intercept form of a line is <em>y = mx + b</em> where <em>m </em>is the slope and <em>b </em>is the y-intercept. In this case, the line is clearly increasing in value, so it has a positive slope or m. This rules out B and C as options. The y-intercept, or where the line intersects with the y-axis is at -4 for this. So, b = -4. If we want to write it out as an equation : <em>y = mx - 4 </em>where <em>m </em>has to be positive. The only option is D which is our answer. Hope I could help!  :)

It would be choice D. Since it starts at -4, this would be the b part of the slope-intercept equation. You can then see that it goes up 1, over 2 continuously. This would be the m part of the slope-intercept equation. Finally, it would be a positive 1/2 since it it going to the right.

Lola is saving money for a new bike. The first month, she saves $50 from her birthday. Lola plans to save $10 per month thereaft
weqwewe [10]
So this can be translated like the following:
Bike costs= 173 dollars She currently has 107. She saves 11 dollar per week to get the bike so the formula is:
173 = 107 + 11X where X is the number of weeks

Step 1: bring the 107 to the other side to get 173-107 = 11X
Step 2: divide both sides by 11 to solve for X to get this (173-107 )/11 = X
Step 3: Calculate and simplify 66 / 11 = X which is the same as X= 6

So the answer is it will take jennifier 6 weeks to save for the bike.

Mathew is watching a car race on TV. His favorite car covered 10 laps of 3.6 miles each in 18 minutes. What is average speed of
Karo-lina-s [1.5K]
In the given question, all the necessary information's are already provided. Using these information's it is easy to find the average speed of the car in miles per hour. It is given that the car covers 10 laps in 18 minutes and each lap is 3.6 miles in length.
Total distance covered by the car = (10 * 3.6) miles
                                                     = 36 miles
Now we have to convert the time from minutes to hours. So
18 minutes = 18/60 hours
                   = 3/10 hours
Now we can easily calculate the average speed of the favorite car of Mathew.
Average Speed = 36 * (10/3) miles/hour
                           = 120 miles/ hour
