Shop Rite has jeans on sale for 3/10 off. Save More has jeans on sale for 33% off. Which store has a better deal? Explain.
umka21 [38]

save more has a better deal because when you convert 33% into a fraction out of ten it becomes 3.3/10 and shop right is 3/10 so 3.3 is greater than 3.

What is the average rate of change of the function f(x) = 4x – 2 over the interval x = –1 and x = 2?
Alexeev081 [22]

Answer:

4

Step-by-step explanation:

Given: f(x)=4x-2

To find:  average rate of change of the function f(x)=4x-2 over the interval x=-1 and x=2

Solution:

Take a=-1,\,b=2

Find f(a),\,f(b)

f(a)=f(-1)\\=4(-1)-2\\=-4-2\\=-6\\\\f(b)=f(2)\\=4(2)-2\\=8-2\\=6

Average rate of change of the function =\frac{f(b)-f(a)}{b-a}

=\frac{f(2)-f(-1)}{2-(-1)}\\\\=\frac{6-(-6)}{3} \\\\=\frac{12}{3}\\\\=4

Please please help me with this

N=1→an=a1 (first term)=16 (on the graph for n=1)→First term = 16
n=2→an=a2 (second term) = 4 (on the graph for n=2)→Second term = 4

ratio=(Second term)/(First term)=a2/a1=4/16
Simplifying the fraction dividing the numerator (4) by 4 and the denominator (16) by 4:
ratio=(4/4)/(16/4)→ratio=1/4

Answer: Option A. First term = 16, ratio = 1/4

The least number of possible bags of beads packed would be 2 because the greatest common factor is 2. To find how many of each bead is packed into each bag you would have to divide 14 and 2 which is 7, 16 and 2 which is 8, and 18 and 2 which is 9, so there will be 8 read beads, 9 orange beads, and 7 green beads.


Hope this helps!!!!
