Answer:
$2.81
Step-by-step explanation:
1.25 is 100% of the price
125% + 100% = 225%
x = price by august
x = 225% (1.25)
225% = 2.25
2.25(1.25) = 2.8125 ≈ $2.81
Another way to see it:
[tex]\frac{1.25}{x}[/tex] = [tex]\frac{100}{225}[/tex]
225(1.25) / 100 = 2.8125
Answer:
11.25
Step-by-step explanation:
Write the quadratic function f(x) = 3(x + 1)(x – 7) in standard form.
A)
f(x) = x2 – 18x – 21
B)
f(x) = 3x2 – 18x – 21
C)
f(x) = x2 – 6x – 7
D)
f(x) = 3x2 – 6x – 7
Answer:
B
Step-by-step explanation:
Given
f(x) = 3(x + 1)(x - 7) ← expand the factors using FOIL
= 3(x² - 6x - 7) ← distribute the parenthesis
= 3x² - 18x - 21 → B
Give an example of an absolute value inequality whose answers falls between two values. Give an example of an absolute value inequality whose answers fall outside of two values. What creates the difference? Be specific. *
Answer:
A) Suppose we have an onedimensional situation.
in the 0 of our x-axis, we have a fruit tree, and we want to rest at a distance no bigger than 6 ft of the tree, then all the possible positions of our resting place are:
x ∈(-6ft, 6ft)
we can write this as: IxI < 6ft
b) now we think the opposite situation, we want to rest at least 6ft away from the tree, then we have that:
x ∉ [-6ft, 6ft].
or IxI > 6ft.
So you can see that the difference in those two cases is if we want to be "inside a given range" (for the first case) or "outside a given range" (for the second case).
A shirt that originally cost $38.00 is on sale for 30% off. What is the sale price of the shirt?
1.
$11.40
2.
$26.60
3.
$29.23
$49.40 this is due today pls help.
_________________________________
Solution,
Marked price (MP)=$ 38.00
Discount%=30%
Sale price (SP)=?
Now,
Discount amount= discount% of MP
=30%of 38
=$ 11.4
Again,
Sale price(SP)=MP-Discount
= 38-11.4
=$26.60
The right answer is $ 26.60
Hope it helps...
Good luck on your assignment
_______________________________
Answer:
$26.60Step-by-step explanation:
[tex]orginal \: \: \: \: price = 38.00[/tex]
[tex]discount \\ percentage= 30\%[/tex]
First we have to find the discount.
[tex]discount = 38 .00\times \frac{30}{100} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 11.40[/tex]
Now let's find the sales price of the shirt.
[tex]sales \: \: \: price \\ =original \: \: \: \: price - \: discount \\ = 38.00 - 11.40 \\ = 26.6 0\\ [/tex]

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
A = -√8n² ( 12 )
On simplifying , we get
A = -√108n²
Taking the value of n outside , we get
A = -n√108
On further simplification , we get
A = -n3√12
A = -3n√12
Hence , the value of the expression after simplification is A = -3n√12

Answer:
|-30| + |25|
Step-by-step explanation:
The helicopter is 25 ft above the ledge. The stunt actor is 30 below the edge. The distance from the helicopter to the stunt actor is the sum of the two distances, 25 + 30 = 55 ft. The correct expression must equal 55.
A. |-30| + |25| = 30 + 25 = 55
B. -30 - 25 = -55
C. -30 + 25 = -5
D. |-30| - |25| = 30 - 25 = 5
The correct expression is |-30| + |25| since it it the only expression that equals 55.

Solve for x. 9x=3x−3
Answer:
x=-1/2
Step-by-step explanation:
9X = 3X + -3
Reorder the terms:
9X = -3 + 3X
Solving
9X = -3 + 3X
Solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '-3X' to each side of the equation.
9X + -3X = -3 + 3X + -3X
Combine like terms: 9X + -3X = 6X
6X = -3 + 3X + -3X
Combine like terms: 3X + -3X = 0
6X = -3 + 0
6X = -3
Divide each side by '6'.
X = -0.5
Answer:
x = -0.5Step-by-step explanation:
In an equation, the goal is the isolate the variable. We do this by undoing the operations done to result in the given equation.
Step 1: Subtract 3x
6x = -3
Step 2: Divide by 6
-0.5
Step 3: Check
9(-0.5) = 3(-0.5) - 3
-4.5 = -4.5 ✅

What is the complete factorization of the polynomial below?
x3 + x2 + 4x + 4
x = -1
x = 2
x = -2
Reformatting the input :
Changes made to your input should not affect the solution:
(1): "x2" was replaced by "x^2". 1 more similar replacement(s).
Step by step solution :
Step 1 :
Checking for a perfect cube :
1.1 x3+x2-4x-4 is not a perfect cube
Trying to factor by pulling out :
1.2 Factoring: x3+x2-4x-4
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: x3+x2
Group 2: -4x-4
Pull out from each group separately :
Group 1: (x+1) • (x2)
Group 2: (x+1) • (-4)
-------------------
Add up the two groups :
(x+1) • (x2-4)
What is the area of the triangle?
3
2
6
Answer:
A = 6 units^2
Step-by-step explanation:
The area of a triangle is given by
A = 1/2 bh
A = 1/2 (6)(2)
A = 6 units^2
Answer:
6 units^2
Step-by-step explanation:
The area of a triangle can be found using the following formula.
a=(bh)/2
where b is the base and h is the height. In this triangle, we know that 6 units is the base. We also know that 2 units is the height, because the height should form a right angle(little square) with the base.
b=6
h=2
Substitute these values into the formula.
a=(6*2)/2
Multiply 6 and 2 first.
a=12/2
Divide 12 by 2
a=6
Add appropriate units. Area always has the unit squared.
a= 6 units^2
The area of the triangle is 6 square units.
