Answer:
Both are proportional, because as the value of x change (increases or decreases), the value of y changes (increases or decreases).
The first equation (y = 25x) could represent that amount of teachers per students. If x = teachers (let's say there is 1 teacher), then y = students (1 teacher would teach a class of 25 students).
The second equation (y = 5x + 25) could represent the amount of money you could earn babysitting. The starting/base amount would be $25, and you would earn $5 more for every hour you babysat.
Step-by-step explanation:
This is pretty simple! Just add the cost of each procedure together.
65.97 + 127.12 + 94.50 = $287.59
The answer would be C b/c negative 2 times 11 is positive 22 and 2negatives equal a positive and then negative 5 times 4 equal 20 it would be 22/20 divide be top and bottom by 2 and you get your answer .
Answer:
The centroid of a triangle is also the center of gravity of the triangle.
Step-by-step explanation:
The centroid or the center of gravity of a triangle is that point through which all the mass of a triangle balances. We can also call it the call it the center of mass. Also, the centroid is the point, where the triangle's medians intersect.
Therefore, the correct answer is option A.
