Answer:
Step-by-step explanation:
b. 1000 messages: 30 dollars
1,725 messages: 51.75
c. 2,000
2,500
600
b. 37.5
I cant do the rest because they have graph stuff :)
12,419,293
an increase of 100,000 = 12,519,293
an increase of 1,000,000 = 13,419,293
a decrease of 10,000 = 12,409,293

Answer: x = (
y-2)^2 +
5</h3>
In other words, y-2 goes in the first box and 5 goes in the second box.
=================================================
Work Shown:
y^2 - 4y - x + 9 = 0
y^2 - 4y + 9 = x
x = y^2 - 4y + 9
x = y^2 - 4y + 4 + 5 .... rewrite 9 as 4+5
x = (y^2-4y+4) + 5
x = (y-2)^2 + 5 .... apply the perfect square factoring rule
So we'll have y-2 go in the first box and 5 goes in the second box
note: One version of the perfect square factoring rule says (a-b)^2 = a^2-2ab+b^2.
Answer:
7x²sqrt(x)
Step-by-step explanation:
7x^(5/2)
7x^(2½)
7x^(2+½)
7x² × x^½
7x²sqrt(x)
sqrt: square root
