Answer:

B

Step-by-step explanation:

If two quantities have a direct variation, their graph will originate from the point of intersection at the origin.

Among all graphs, only Nikiya's intersects the origin, thus the answer is B.

Answer:

Only B. Nikiya's

Step-by-step explanation:

Mark's charges do not exhibit a direct correlation with the time spent talking since the cost for 0 hours is not equivalent to 0 dollars.

The constant of variation for Nikiya’s plan is 15

which signifies Nikiya’s cost per hour.

Answer and explanation:

Algebra revolves around the fundamental idea of using letters known as variables to represent quantities, which allows for solving for unknown values. Essentially, algebra involves transitioning from what is known to what is unknown to ascertain those unknown results. For instance, if we know a specific item was purchased twice but we're unsure of its price, we can denote this unknown price as 2a or 2p, depending on the selected variable. If the total spending for those items is, say, $50, we can set up the equation 2a = $50, which leads us to find that the cost per item is $25.

Algebra can also manifest itself in expressions, commonly referred to as algebraic expressions, which can be incorporated into equations, such as the previously mentioned 2a = $50. These expressions may take forms like 2a + 3b, where a and b designate the costs of different products that were acquired in quantities of 2 and 3, respectively.

PIT_PIT [12445]
The compound inequality for the temperature range protected by antifreeze is -40 < t < 284. Antifreeze operates effectively from −40°C to 140°C. By using 't' for temperature, the range in Celsius can be established as -40 < t < 140. The conversion formula for Celsius to Fahrenheit allows us to find the corresponding Fahrenheit temperatures for these Celsius values.
