Answer:
The answer is B:subtract 1,add x,divide by 4
The other answer is D:add x,subtract 1,divide 4
Step-by-step explanation:
when you subtract 1 you isolate 3x so the equation looks like 3x=-x+3
the next step is to add x to both sides so you isolate the x to one side after doing that your equation should look like 4x=3,after this you divide both sides to the solution x=
The answer is also D because if you add x to both sides u isolate x to the left side so the equation will look like 1+4x=4 the next step will be to subtract one from each side and after doing this the equation should look like 4x=3 which should look familiar because its the same exact solution as B was so the answer to this choice is x=
With that evidence I can reasonably say that answer to the question is B,and D

Answer
D.25x2 – 36
Explanation
A. x² – 16x + 64
product = 64
sum = -16
factors: -8 and -8
x² – 16x + 64 = x² - 8x - 8x + 64
= x(x - 8) - 8(x - 8)
= (x - 8)(x-8) = (x-8)² ⇒ Not a difference of squares
B.x² + 4 = (x² + 2²) ⇒ Not a difference of squares
C.9x² – x – 36
product = - 324
sum = -1
Factors: none
9x² – x – 36 ⇒ Has no perfect roots.
D.25x² – 36
25x² – 36 = (5x)² - 6² ⇒ This is the difference of squares.
Answer D
25x²-36=(5x)²-6²

What is the percentage?
The percentage is a ratio that can be expressed as a fraction of 100.
Let the required number be x.
Then, it follows that 1344 is 240% of x:
1344 = 240% of x
1344 = 240x/100
1344 = 12x/5
x = 1344×5/12
x = 560
Hence, the number is 560.

The equation that models this relation is y = 70/x. So, option (D) is the correct answer.
What is constant of proportionality?
The constant of proportionality is the ratio of two proportional values at a constant value. Two variable values have a proportional relationship when either their ratio or their product gives a constant.
For the given situation,
The values are y = 10 and x = 7
y varies inversely with x.
⇒ ∝
To remove proportionality we introduce a constant 'k'.
⇒
Substitute the values of x and y,
⇒
⇒
Now substitute the value of k = 70 in y,
⇒
Hence we can conclude that the equation that models this relation is y = 70/x. So, option (D) is the correct answer.

Step-by-step explanation:
If a point (x, y) is reflected across y = -x, coordinates of the image point will be,
(x, y)→ (-y, -x)
Following this rule,
Vertices of the triangle will be,
(3, 1) → (-1, -3)
(3, -2) → (2, -3)
(6, -3) → (3, -6)
Therefore, image of the given triangle A will be,
(-1, -3), (2, -3) and (3, -6)

What is 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. LHS = RHS is a common mathematical formula.
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.
Quantity Demanded is inversely related to price as Quantity Demanded increases then price decreases.
Initially,
Q = 50 when P =70
Q = 51 when P=69
Finally, Q=0 when P =120
Q=120 when P=0
Slope = -1
Use the point slope formula
y=mx + b
or Q=-P+b
50= -70+120
b=120
So, Q=-P+120 is the equation for the demand curve
now, Revenue
PQ = P(-P+120) = -P2 + 120P
R' = -2P + 120 and set it equal to zero and solve for P
-2P+120 = 0
2P=120
P = $60
That is the revenue maximizing price plug it into the demand curve equation
Q=-P+120
Q=-60+120
Q = 60
Thus, the number of skateboards sold that maximizes revenue is 60
and, the maximum revenue = 60x60
= $3,600 for a week
