Answer:

  B.  2x^2 -5x +2y

Can someone help me out?
Anarel [89]

Answer:

So the value of s  = 7 cm

Step-by-step explanation:

We know that, Area of a triangle = 1/2 * b * h

So, base = 24 cm

height = s

Area = 1/2 * b * h

=>84 = 1/2 * 24 * h

=>84 = 12 * h

=>84 / 12 = h

=> 7 = h (in cm)

Hope this helps, please mark me as brainliest!! Thank you!

Define a function. Describe what the vertical line test is used for. Describe a real life situation that can be represented by a
Marrrta [24]
A function is a relationship with a quantity (number). For example, if you made a table, and had one side be 1 2 3 4 5 (X axis) and then the y axis (other side) be 5, 10, 15, 20, 25, the function (rule) would be y= x5. The vertical line test is used to see if a graph has a function or not, so if it creates a vertical line on a graph, it has a function.
A real life situation would be miles per hour, so, for the x axis (hours) it said 1, and for the y axis (miles) it would be 60, this means in a duration of 1 hour you went 60 miles. Well, lets say you went 2 hours driving, the miles would be 120. 
For 3 hours, it would be 180. The function here is y= x60!
