Answer:
y=4x+7.75; continuous
Step-by-step explanation:
Let’s first establish the equation. Julie requires one segment of yarn measuring 7.75 inches: that's already known.
y = 7.75
Now, for the four pieces of yarn, each will be of equal length x. If she wants them to measure 1 inch, she'd need 4 inches of yarn. Therefore, the calculation would be:
y = 7.75 + 4x
Now, is this graph discrete or continuous? Continuous indicates there's a smooth line without gaps, while discrete has interruptions or spaces. In this scenario, x is continuous, as Julie can cut the yarn to any size for the four pieces. She is not limited to whole numbers; each piece could be, for instance, 2.5 inches or 3.1415 inches.
Based on the provided information about the metals' melting point, boiling point, and density, the response is A. The gold sample transitions from liquid to gas at the highest temperature, while the copper sample occupies the most volume. Gold's boiling point is the highest at 2660, and copper has the lowest density, which correlates with a larger volume since density is defined as mass divided by volume.
Begin by determining the increase in price for the iPads: $50 multiplied by 10 equals $500. Thus, the iPad's price was raised by $500. Next, subtract this total from the original iPad price: $5,000 minus $500 results in $4,500. This indicates that the actual cost for 10 iPads, unadjusted by the increase, stands at $4,500. To find the individual iPad cost, divide that total by 10, leading to $4,500 divided by 10, which gives $450. Therefore, the manufacturing cost of each iPad is $450.
Answer:
-1.7x -3
Step-by-step explanation:
−4.2x+3 +2.5x−6
I prefer to align them one above the other.
−4.2x+3
2.5x−6
