What is the value of g(-9) for the function g(x) = x2 - x?
Answer:
72Step-by-step explanation:
Given the function;
g(x) = x^2 - x
We are to find g(-9)
g(-9) = (-9)² - 9
g(-9) = 81 - 9
g(-9) = 72
hence the value of g(-9) is 72

Sindhu’s present age is thrice of Shilpa. If Shilpa’s age three years ago was x, then Sindhu’s present age is
3 (x – 3)
3x + 3
3x – 9
3(x + 3)
Answer:
I think "D"- 3(x + 3)
Step-by-step explanation:
as 3 years ago - x
so present age of shilpa - x +3
~~~~~~~~~~~~~
present age of sindhu - 3 (x+3)
i guess : )
Shilpa's age three years ago
Shilpa's age now = x + 3
Sindhu's age now = 3(x + 3)

(8th grade)Use the elimination method to solve the system.
4x+6y=10
2x+5y=1
4x+6y=10
-
2x+5y=1
= 2x+y=9
2x=9-y -1
9-y+5y=1 ( using 1)
4y=1-9
y=-8/4
y=-2
2x=9-(-2)
2x=11
x=11/2

a rectangle is 6 times as long as it is wide. the perimeter is 140 cm. find the area of the rectangle. round to the nearest tenth if necessary.
Answer: [tex]w = 10[/tex]
Step-by-step explanation:
Our perimeter will be 140 cm and our width of the rectangle will be 6w. We will then divide 14w and 140 by 14 so we can get w by itself. Then, we will divide the perimeter by the width.
Step 1: Let 6w will be our length and let the perimeter be 140 cm.
[tex]6w, P = 140 cm[/tex]
Step 2: Perimeter means that you add up all the 4 sides of the rectangle.
[tex]P = 140 = w + w + 6w + 6w = 14w[/tex]
[tex]P = 140, 14w[/tex]
Step 3: Divide both sides 14 to get the single w variable.
[tex]\frac{140}{14} = \frac{14w}{14}[/tex]
Step 4: Simplify.
[tex]10 = w[/tex]
Step 5: Flip sides.
[tex]w = 10[/tex]

Step-by-step explanation:
The bike store marks up the wholesale cost of all of the bikes they sell by 30%. Andre wants to buy a bike that has a retail price of $125. We need to find the wholesale (original) price of this bike. What percent of the wholesale (original) price is the retail price?
Answer:
Wholesale Price = $96.15Retail price percentage = 130%Step-by-step explanation:
Wholesale price was marked up by 30% and became $125.
Assume wholesale price is x. Expression will be;
125 = x + (30% * x)
125 = 1.3x
x = 125/1.3
x = $96.15
Retail price percentage = 125/96.15
= 1.30
= 130%

Answer:
The length= 16cm
The width= 6cm
The two long sides are 8cm both so 8 + 8 = 16
And the two short sides are 3cm both so 3 + 3 = 6
So your length should be 16cm and your width 6cm

Kristopher has a coupon for $10 off any item at his favorite electronics shop. If he plans to use the coupon to purchase and item that costs $80, by what percentage will the price be decreased before tax?
Answer:
12.5%
Step-by-step explanation:
Kristopher has a coupon for $10 off any item at his favorite electronics shop. If he plans to use the coupon to purchase and item that costs $80, by what percentage will the price be decreased before tax?
The formula for Percentage Decrease =
Decrease in price/ Initial price × 100
Decrease in price = $10
Initial price = $80
Hence:
$10/$80 × 100
= 12.5%
Hence, the percentage the price will be decreased by before tax is 12.5%
