Tables 4 and 6

Look at the y-values as x-values are same for all tables.

Tables 1 and 5 - linear function as the differences are same.
Tables 2 and 3 - exponential function as the ratios are same.
Tables 4 and 6 - seem quadratic as there are repeat values showing the symmetry.

Hi, you've asked an incomplete question. Here are the remaining questions:

a) Describe what each region in the Venn diagram represents.

Region I: In drama club, not in step team.

Region II: In both clubs.

Region III: In step team not in drama.

Region IV: Not in either club.

b) How many students were in only one of the two clubs?

c) How many students were in the drama club or in the step team?

d) How many students were surveyed?

Attached is the Venn diagram depicting the regions.

Explanation:

b) By adding the number of students that like drama club and those that like step club we can derive the answer: 34 + 27 = 61.

c) By adding 34 + 27 + those that like both (14) = 75.

d) The total number of students surveyed is gotten by summing any number in attached the diagram: 34 + 27 + 14 + 13 = 88.

What is the y intercept of (-6, -5) when the slope is -2/3?

Alecsey [184]

X must be increased by 6 to get its value to be 0. Then the corresponding change in y will be (-2/3)*6 = -4. That value added to -5 makes it -9.

The y-intercept will be -9.

A textbook store sold a combined total of 480 history and math textbooks in a week. The number of history textbooks sold was two

Gwar [14]

H + m = 480
h = 2m

2m + m = 480
3m = 480
m = 480/3
m = 160 <=== there were 160 math books

h = 2m
h = 2(160)
h = 320 <=== there were 320 history books

Given f(x) =x-7 and g(x) =x2 find g(f(4))

8090 [49]

Answer: g(f(4))=9

Step-by-step explanation:

To find g(f(4)), you first find f(4). Then, you plug it into g(x).

f(4)=4-7 [subtract]

f(4)=-3

Now, we know f(4) into g(x).

g(f(4))=(-3)² [exponent]

g(f(4))=9

Now, we know that g(f(4))=9.
