Answer:
James answered 51 questions correctly.
Step-by-step explanation:
1) Slide the decimal 2 places to the left in the percentage (85% = .85)
2) Multiply total by new decimal (60 x .85)
3) All done! (51)
Keep in mind that 100% is just 1 whole. Therefor 85% of one whole is .85. In this problem, 60 represents our whole.
y = abˣ
20 = ab¹
20 = ab
b b
20/b = a
y = abˣ
4 = (20/b)b²
4 = 20b
20 20
¹/₅ = b
y = abˣ
20 = ¹/₅b¹
20 = ¹/₅b
¹/₅ ¹/₅
100 = b
y = abˣ
y = 100(0.2)ˣ
Answer:
The correct answer is C) f(x) = 1,200(0.97)/\x
Step-by-step explanation:
Hope this helps! :)
Slope = y2-y1/ x2-x1
Here x1 is 4
Y1 is -7
X2 is 4
Y2is 8
Slope = 8-(-7)/4-4
= 15/0
Undefined
