Fun fact
if f(a)=b then f⁻¹(b)=a
so
if f⁻¹(b)=a then f(a)=b
so we find f(x)=27 and the solve for x
f(x)=3x=27
3x=27
divide both sides by 3
x=9
so if f(9)=27 then f⁻¹(27)=9
problem solved
answer is 9
So, problem statement tells you that 1lb = 16oz and that 1oz = 28.3g. That means that 1lb = 16 * 28.3g = 452.8g
You have three items, convert their weights to grams:1) 800g2) 1.6lb = 1.6 * 452.8g = 724.48g3) 30oz = 30 * 28.3g = 849g
So, sorting from greatest:3, 2, 1, or: 30oz, 1.6lb, 800g.
Find the GCF (Greatest common factor) of all the numbers.
There will be 4 pencils. 5 erasers. 8 paper clips. Hope I could help!
Btw- the GCF is 5.
Answer:
x - intercept = (-7.5, 0)
y-intercept =(0, 5.5)
Step-by-step explanation:
Line is intersecting x and y axes at points (- 7.5, 0) and (0, 5.5) respectively.
Therefore, x - intercept = (- 7.5, 0) and y-intercept =(0, 5.5).
