30 POINTS!!!!! PLEASE HELP
Hoochie [10]

Answer:

a) For a constant increment in x-variable, there is a constant increment in y-variable, for example, for x = 0 to x = 0.5 (increment = 0.5) y-variable goes from 60 to 62 (increment = 2); the same is valid for any couple of (x,y) values. This behaviour is characteristic of linear equations.

b) slope:

m = (increment in y-variable)/(increment in x-variable) = 2/0.5 = 4

y-intercept:

y1 = m*x1 + h

60 = 4*0 + h

60 = h

equation: y = 4x + 60

where y represents scores and x represents hours spent studying

c) The slope indicates that you need to study 1 hour to increase your score in 4 points

The y-intercept indicates that you will get at least a score of 60, even though you hadn't studied

Find the third side of a right triangle if the hypotenuse is 14 km and one side is 9 km
Galina-37 [17]
14^2 - 9^2 = a^2
Easy enough
14^2 = 196
9^2 = 81
196 - 81 = 115
The square root of 115 = 10.72


The third side is 10.72km

What is the sum of -19 and the product of 48 ?
lord [1]
-16 and -3

I just used 24 and 2, adding &/or subtracting to opposite sides until I got 16*3=48, whether they be positive or negative.

Add -16 and -3 together and you get -19.

Hope this helps you! :)
