1) the vertex of a parable is given for two points, ( -b/2a, -b2-4ac/4a)
2) Now substitute the values in the equation
x = - (-8)/2(-2) = 8/ -4 = -2
y = -(8^2-4(-2)(1)/ 4(-2) = -(64-8) /-8 = 56/8 = 7
v(-2,7)
Answer: I'll simplify the inequality
11. x≤8
12. y<8
13. z>2
14. b≥12
15. c<1.8
16. already solved a≤0
Answer: 900 inch
There is 3 ribbon in this question, Red ribbon(R), green ribbon(G) and purple ribbon(P). The relation would be
1. R= 9 inch
2. R= 1/10 G
3. P= 10 G
If you insert equation 1 into 2 then you will get:
9inch= 1/10G
G= 90 inch
After that insert the new equation into equation 3:
P= 10x 90 inch
P= 900inch
Answer:
Equation which can be used to find the number of weekly payments w
is 300 = 60 + 3 w.
Step-by-step explanation:
Here, the selling price of the TV =$300
The initial TV payment = $60
Per week payment of TV = $30
The number of weeks, the payment is made = w
So, the amount paid for TV in w weeks = w x ( Payment in 1 week)
= w x ( $30) = 30 w
So, The total SP of TV = Initial Payment + Payment made in w weeks
⇒ 300 = 60 + 3w
Hence, equation which can be used to find the number of weekly
payments w is 300 = 60 + 3 w.
Answer:
$231.42
Step-by-step explanation:
Find the tub radius. It is C = 2πr, which here is C = 6.28(5.5 ft ) = 34.54 ft.
The border costs $6.70/ft. Multiply $6.70/ft by 34.54 ft:
($6.70/ft)(34.54 ft) = $231.42
