Answer:
she is incorrect because if she was given a 20% discount the amount she would have to pay is 38.4
Step-by-step explanation:
48 x .2 = 9.6
48 - 9.6 = 38.4 not 40
Answer:
The answer to this question would be B:
Based on the question, since the weight of the weight plates are 20 lbs, this would be represented by the 20x in the function. As well, the 5 lb barbell would be represented by the 5 in the function. The range of the function is determined by the amount of weight plates are added. So if I added one weight plate the equation would equal, f(x) = 20(1) + 5 = 25. This continues on the more and more weight plates you add.
Hope this reached you well :)
Step-by-step explanation:
20 = weight of the weight plates
x = amount of weight plates.
5 = weight of the barbell
f(x) = 20(0) + 5 = 5
f(x) = 20(1) + 5 = 25
f(x) = 20(2) + 5 = 45
f(x) = 20(3) + 5 = 65
f(x) = 20(4) + 5 = 85
Answer:
Step-by-step explanation:
So in y=mx+b form
m is slope
b is y intercept
y=1/2x+b
solve for the y intercept
and
Ur done
EDIT:
m is the slope
so m is 1/2
b is y-intercept
and since the line passes through (2,6) and the line has a slope of 1/2 that means the y-intercept is (0,5).
replace in equation.
y=1/2x+5
