Answer:
C
Step-by-step explanation:
f(x) = |x|: f(0) = 0, f(1) = 1, f(-1) = 1
f(x) + 5 = |x| --> f(x) = |x| - 5: f(0) = -5, f(1) = -4 f(-1) = -4
Therefore it shifts down by 5
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:
j=13
Step-by-step explanation:
The equation for this problem is 7j=91.
I would divide 7 on both sides, which would be j=13.
