Helga [31]3 years ago

Answer:

Step-by-step explanation:

Range goes from the lowest point on a graph to the highest point, not including anything in between those 2 extremes. We will evaluate the quadratic for the values given. First f(2):

f(2)=(2)^2-5 so

f(2) = -1

Now, f(4):

f(4)=(4)^2-5 so

f(4) = 11

Now, f(7):

f(7)=(7)^2-5 so

f(7) = 44

The lowest y value is -1 and the highest is 44, so the range is from -1 to 44 (I can't tell which of your choices reflects that because it's too small!)

Zina [86]

Answer:

(A - B)' = {2, 4, 5, 6, 7, 8, 9}

(A n B) = {2, 4}

Step-by-step explanation:

Given the set :

U = { 1 , 2 , 3 , 4 , 5 ,6 , 7 , 8 , 9 }

A={1 , 2 , 3 , 4 } , B= {2 , 4 , 6 , 8 }

(A - B) = elements of A which are not in B

(A - B) = {1, 3}

(A - B)' = the complement of A - B ; element in the universal set which are not in A - B

(A - B)' = {2, 4, 5, 6, 7, 8, 9}

(A n B) = elements in both set A and set B

(A n B) = {2, 4}

<h3>I'll teach you how to solve x= 12 - y, 2x + 3y = 29</h3>

------------------------------------------------------------

x= 12 - y, 2x + 3y = 29

Substitute x=12-y:

[2(12-y)+3y=29]

Isolate y for 2(12-y)+3y=29:

2(12-y)+3y=29= y= 5

Substitute y=5:

x=12-5

12-5= 7

x=7

Your Answer Is (C) x=7, y=5

plz mark me as brainliest if this helped :)
