Answer:
2x-(-8y)
Step-by-step explanation:
adding = subtracting a negative number
Just plus in x for -3
f(x) = 4(-3)^2 + 3(-3) - 11
f (x) = 4(9) -9 - 11
f(x) = 36 - 20
f(x) = 16
Answer:
Step-by-step explanation:
a) You want the ratio ...
(Salena's earnings)/(Drew's earnings)
It is convenient to fill in the numbers from the first line of the table:
(Salena's earnings)/(Drew's earnings) = 31/33
b) Salena's earnings in 4 days will be double her earnings in 2 days.
4 days' earnings = 2×$62 = $124
c) Salena's earnings in 30 days will be 10 times her earnings in 3 days.
30 days' earnings = 10×$93 = $930
_____
<em>Alternate solution</em>
You can go to the trouble to write an equation for Salena's earnings (s) in terms of the number of days (d). That would be ...
s = 31d
Then you can fill in d=4 or d=30 to find her earnings for 4 or 30 days. For this problem, enough information is given in the table that shortcuts can be used, simplifying the problem immensely.
Answer:1/8
Step-by-step explanation:
12.5% = 12.5/100 = 0.125=0.125/1×1000/1000=125/1000=1/8
Hi!
The expression would be (8 x t)s
Hope this helps !
