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
Answer:
6900000 + (6900000 * x) = 7400000
This equation is telling us 6900000 plus 6900000 times a specific percent will get you 7400000, which is what you want.
6900000 + (6900000 * x) = 7400000
6900000 + 6900000x = 7400000
Subtract 6900000 from both sides.
6900000x = 500000
Divide both sides by 6900000
x = 0.0724637681, or .07 when rounded to the nearest tenth.
convert .07 to a percentage by moving the decimal point two places to the right.
.07 = 7%
The sales of the children's athletic shoes rose about 7%

Answer:
A Fever is an Inmune system response.
Step-by-step explanation: This is actually an immune system response. A rise in temperature can kill some microbes. Fever also triggers the body's repair process.
