Like the answer below, you can't spend more thatn 100% which is what you have

the question is worded badly
read it
if maxine spent 15 hours last week ant 18 hours this week, she spent 120% of this week doing homework

I would guess we shoudl compare the increase
if the question is like, this week is 120% of last week, the answer would be correct
because
18=120% of 15
18=1.2*15
18=18
true


but, if you only red the question, then
each week=7 days, 24 hours, 7*24=168
15/168=9%
18/168=11%
not even close to 120%


I would say that the time she spent this week was 120% of the time last week

Wrong because you can't spend more than 100% if a week doing something

Solve the inequality 2c/3+1>7
beks73 [17]

Answer:

c > 9

Step-by-step explanation:

(2c/3) + 1 > 7     subtract 1 from both sides

2c/3 > 7 -1

2c/3 > 6  (multiply both sides by 3)

2c > 6(3)

2c>18    (divide both sides by 2)

c > 18 / 2

c > 9

How is the range of a set of data different from the IQR
Gnom [1K]
The range is the difference betweem the largest and smallest NUMBERS in the whole piece of data. The IQR is the difference between the largest and smallest QUARTILES. For example, if you had the data 1,2,3,4,5: 5-1=4 would be the range and...(4-2)=2 would be the IQR. Hope this helped! :)

The function f(x)=x^2 -6x+3 is transformed such that g(x)=f(x-2). Find the vertex of g(x).
Lisa [10]

Answer:

g(x) = (x-2)^2 -6(x-2) +3

g(x) = x^2 -4x +4 -6x +12 +3

g(x) = x^2 -10 x +19

g(x) = x^2 -10 x + 25 +19 -25

g(x) = (x-5)^2 -6

y= (x-h)^2 -kk

Where h,k represent the vertex and we got:

(h,k)= (5,6)

(5,6)

Step-by-step explanation:

We have this original function given :

f(x) = x^2 -6x +3

And we want to find the vertex for this new function g(x) = f(x-2) and we have:

g(x) = (x-2)^2 -6(x-2) +3

And solving the square we got:

g(x) = x^2 -4x +4 -6x +12 +3

And adding similar terms we got:

g(x) = x^2 -10 x +19

Now we can complete the square like this:

g(x) = x^2 -10 x + 25 +19 -25

g(x) = (x-5)^2 -6

The general equation is given by:

y= (x-h)^2 -kk

Where h,k represent the vertex and we got:

(h,k)= (5,6)

(5,6)
