Answer:
−y−81
Step-by-step explanation:
If she already gets the first two, thats a given 100% situation. then it is just 1/4
Answer:
Adults = x
Students = y = x + 40. 40 more student than adult
Adult = $8, Student = $6
Total for Adults = 8*x = 8x
Total for students = 6*y = 6y
Total = $1920
8x + 6y = 1920
Hence system of equations are:
y = x + 40
8x + 6y = 1920
300/4*5=375 miles
hope it helps
Answer:
slope = 5
Step-by-step explanation:
The slope is the rate of change of the function. Although not mathaticaly rigorous, the slope of the line is the same as the slope of an uphill road. It's just a number that shows you how much the function change for every tiny step you take to the right. In order to calculate it, given that we are talking about a line which slope is constant, you have two pick two points. The slope is the difference of their y coordinates, divided by the difference of their x coordinates.
For example let's pick the following two points:
A(0,0) and B(1,5)
slope = ( y_B - y_A ) / ( x_B - x_A )
= ( 5 - 0 ) / ( 1 - 0 ) = 5
However, the above is a mechanism you can follow even when the exercise is a tough one.
To sum up, the slope is a number that shows you how much tilted is the graph. For every step to the right, how much does the value of the function change?
