Substitute
So, -2x-7 = 3x + 3
+2x. +2x
-7= 5x +3
-5x. -5x
-5x-7= 3
+7. +7
-5x= 10
Divide -5 on both sides and you get x= -2
Then substitute -2 in the first equation
-2(-2)-7
4-7
Y= -3
X\times 2 bc it is correct I think I’m not sure but yeah
Ok....sooo. first. you do a line and number it.
--------------1-------------2-----
as you see the first number in the graph is 1.5 sooo it goes in between number 1 and 2 because its in the middle.
The second is 1.6 sooo this number goes next to 1.6
-------------1--------1.5---1.6-----------------2----------
then you repeat the same with the other.
now idk if this answer the question but i hope someone else makes sure its correct
Answer:
B) Domain: -2≤x≤2 Range: -2≤x≤3
Step-by-step explanation:
The domain is the x-values, in this case all the numbers between -2 and 2. The range is the y-values, which are the numbers between -2 and 3. So the answer is
B) Domain: -2≤x≤2
Range: -2≤x≤3
Let x be a random variable representing the price of a Congo-imported black diamond. Let the higher price be p. Then,
P(x < p) = P(x < (p - mean)/sd) = P(x < (p - 60,430)/21,958.08) = P(z < 2)
Therefore,
(p - 60,430)/21,958.08 = 2
p - 60,430 = 2 x 21,958.08 = 43,916.16
p = 34,916.16 + 60,430 = 104.346.16
Therefore, The required price is $104,346.16
