Okay... so $2.50 is 2/9 of his total savings.... so... 2.50÷2 is 1.25... so... 1.25×7... which is 8.75... so... Nathan deposited $8.75 into his savings account.
Answer:The better option would be the $6.75 per square foot plus a $100 fixed installation fee.
Step-by-step explanation:
B1= 330 ft
B2= 180 ft
B3= 156 ft
Total sq is 666
666 * 6.75 + 100= $4,595.5
666 * 7.25= 4,828.5
Answer:
0.22
Step-by-step explanation:
2/9 as a decimal is 0.22222222
This number rounded off to its nearest hundredth is 0.22

Hey there!
So, here is a visual of the graph.

The definition of symmetric is that there are two equal parts. This would not cut in half equal so it is not symmetric.
The peak is at 1, since 5 is the highest number of dots. So, the correct answer would be:
"It is not symmetric and has a peak at 1." <=== third choice
I hope this helps!

Step-by-step explanation:
Simplifying
(7a + 3b)(7a + -3b) = 0
Multiply (7a + 3b) * (7a + -3b)
(7a * (7a + -3b) + 3b * (7a + -3b)) = 0
((7a * 7a + -3b * 7a) + 3b * (7a + -3b)) = 0
Reorder the terms:
((-21ab + 49a2) + 3b * (7a + -3b)) = 0
((-21ab + 49a2) + 3b * (7a + -3b)) = 0
(-21ab + 49a2 + (7a * 3b + -3b * 3b)) = 0
(-21ab + 49a2 + (21ab + -9b2)) = 0
Reorder the terms:
(-21ab + 21ab + 49a2 + -9b2) = 0
Combine like terms: -21ab + 21ab = 0
(0 + 49a2 + -9b2) = 0
(49a2 + -9b2) = 0
Solving
49a2 + -9b2 = 0
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '9b2' to each side of the equation.
49a2 + -9b2 + 9b2 = 0 + 9b2
Combine like terms: -9b2 + 9b2 = 0
49a2 + 0 = 0 + 9b2
49a2 = 0 + 9b2
Remove the zero:
49a2 = 9b2
Divide each side by '49'.
a2 = 0.1836734694b2
Simplifying
a2 = 0.1836734694b2
take the square root of each side:
a = {-0.428571429b, 0.428571429b}
