2x+p/q=2x+q/p, p DOESNt equal to 0, q doesn’t equal to 0
Answer: If p=q, ______. If p doesn’t equal q, _______.
The equation, [tex] \frac{2 \cdot x + p}{q} = \frac{2 \cdot x + q}{p} [/tex], gives;
When p = q, the number of solutions is infinite.
When p ≠ q, the equation has no solution
How can the given equation be evaluated?The given equation is presented as follows;
[tex] \frac{2 \cdot x + p}{q} = \frac{2 \cdot x + q}{p} [/tex]
If p = q, we have;
[tex] \frac{2 \cdot x + q}{q} = \frac{2 \cdot x + q}{q} [/tex]
[tex] \frac{2 \cdot x + p}{p} = \frac{2 \cdot x + p}{p} [/tex]
Therefore, the equation has an infinite number of solutions when p = Q
If p ≠ q, and x = 3, we have;
[tex] \frac{2 \cdot x + p}{q} = \frac{2 \times 3 + p}{q} = \frac{6 + p}{q} [/tex]
[tex] \frac{2 \cdot x + q}{p} = \frac{6 + q}{p} [/tex]
[tex] \frac{6 + p}{q} [/tex] = \frac{6 + q}{p} [/tex]
6•p + p² = 6•q + q²
However;
p ≠ q
Therefore;
6•p ≠ 6•q
p² ≠ q²
6•p + p² ≠ 6•q + q²
Which gives;
[tex] \frac{6 + p}{q} \neq \frac{6 + q}{p} [/tex]
The equation is not defined when p ≠ q

what is the direction of vector v if it ends at (-3,-10)
The direction of the vector v in standard position is approximately 253.301°.
What is the direction of a given vector?
Vectors in rectangular form present the change of each of the two variables parallel to orthogonal axes. Each point is described by the following definition:
v = (Δx, Δy) (1)
And the direction of a vector is equal to this inverse trigonometric function:
θ = tan⁻¹ (Δy / Δx) (2)
If we know that Δx = - 3 and Δy = - 10, then the direction of the vector is:
θ = tan⁻¹ (- 10 / - 3)
θ = tan⁻¹ (10 / 3)
θ ≈ 253.301°

Which of the following must be a factor of the function
Answer:
(A) (x -2)
Step-by-step explanation:
You want to know a factor of the function whose values given in the table include (x, y) = (2, 0).
Polynomial zerosA polynomial function y = p(x) will have a factor of (x-a) if and only if p(a) = 0.
The table shows y=0 for x=2, so this polynomial function will have a factor of (x -2).
__
Additional comment
The function shown in the table is ...
y = (x -2)²
so it actually has two factors that are (x -2).
You can tell this is a polynomial function of degree 2 because the 2nd differences are constant.
First differences between successive y-values: -7, -5, -3, -1, 1, 3
Second differences between successive first differences: 2, 2, 2, 2, 2.
Eighty meters of fencing is available to enclose the rectangular garden of Mang
Gustin. Give a function A that can represent the area that can be enclosed in
terms of x.
A function that can represent the area that can be enclosed in terms of x is 40x-x².
Given that Eighty meters of fencing is available to enclose the rectangular garden of Mang Gustin.
Area is defined as the amount of space that can be used within a flat surface or the surface of a solid. Perimeter is defined as a continuous line that forms a boundary to define a two-dimensional shape.
Let the length of garden, l=x
and the given perimeter, p=80
As we know, perimeter of rectangle is P=2(l+b).
Now, we will substitute the values and find the value of b, we get
80=2(x+b)
Now, we will divide both sides by 2, we get
80/2=2(x+b)/2
40=x+b
Further, subtract x from both sides, we get
40-x=x+b-x
40-x=b
Now, we will find the area of rectangle by using the formula A=lb.
Substitute the values in above formula, we get
A=x(40-x)
A=40x-x²
Hence, the area that can be enclosed in terms of x is 40x-x².

A rectangular room is 15 ft long and 10 ft wide. A scale drawing of the room had a width of 5 inches.What is the length of the room in the drawing?
Answer:
7.5 inches
Step-by-step explanation:
15 ft long and 10 ft wide becomes 3/2 when converted into a ratio
we now have 3/2 and five inches
3 is 1.5*2
5*1.5 is 7.5
Answer:
7.5in
Step-by-step explanation:
If the original room's dimensions are (15ft x 10ft). Then the new scaled-down version is (?ft x 5in) we can set up a ratio of 10/5 = 2 to find that the scale from the room to the drawing is being shrunk by a factor of 2. So if you take 15/2 you will get your final answer of the new length of 7.5in!

whats the simplest form of b⁴ b²?
Answer:
Step-by-step explanation:
Simplify ((b^4)^4) / ((b^2)^3).First lets simplify the numerator. ((b^4)^4). The notation is b to the fourth power, to the fourth power, which is multiplying sixteen b’s. That explains why we multiple the exponents, to get b^(16) for the numerator.Similarly we simplify the denominator by multiplying the exponents for ((b^2)^3) = b^6.Putting the simplified numerator and denominator together is (b^(16))/(b^6).The six b’s in the denominator cancel six b’s in the numerator for (b^(16))/(b^6) = b^(10). Final answer b^(10).Note, another way to view (b^(16))/(b^6) = (b^(16)) * (b^(-6)) then add the exponents to have the same answer (b^(10))

a)Amount of money left on Pablo's card in dollars = $100 - $15x
= $(90 - 15x)
b) Amount of money left on Teresa's card in dollars= $70 - $10x
= $(70 - 10x)
c) Write an equation to show that the two cards have the same amount of money left on them [don't know how to do this part.
$100 - 15x = $70 - 10x
Let x be the number of pizzas purchased. For each card, write an expression for the amount of money left on the card after purchasing x pizzas.
For Pablo
Keith received a gift card of $100 for a pizza restaurant. The restaurant charges $15 per pizza.
x numbers of pizza costs = $15x
Hence, the amount of money left on Pablo's card after purchasing x pizzas = $100 - $15x
For Teresa,
Mary received a gift card of $70 for a different pizza restaurant. The restaurant charges $10 per pizza.
Hence, x number of pizzas cost =$10 × x
= $10x
Therefore, the amount of money left on Mary's card after she buys x pizzas =
$70 - $10x
Amount of money left on Pablo's card in dollars = __________
Amount of money left on Teresa's card in dollars=____________
Write an equation to show that the two cards have the same amount of money left on them.
To find the equation that shows that the two cards have the same amount of money =
Equation 1 = Equation 2
$100 - 15x = $70 - 10x
Collect like terms
-15x + 10x = $70 - $100
-5x = -30
x = 30/5
x = 6
Hence, anytime Pablo and Teresa buys ,6 pizzas their gift card will have the same amount of money left on them.

A ball was thrown off a bridge. The table relates to the height of the ball above the ground in feet to the time in seconds after it was thrown. Use the data to enter a quadratic model in vertex form and convert it to standard form. Use the model to find the height of the ball at 1.5 seconds.
The peak height reached at 144 feet, and the graph passing through points (0, 120), (1, 144), (2, 120), gives;
1. The vertex form of a quadratic equation is f(x) = a•(x - h)² + k
Where;
a = The leading coefficient
(h, k) = The coordinates of the vertex.
Let t represent the time of travel of the ball and let h represent the height.
From the given table, we have;
f(t) = a•(t - h)² + k
f(0) = 120 = a•(0 - h)² + k = a•h² + k
120 = a•h² + k
f(1) = 144 = a•(1 - h)² + k = a•(h² - 2•h + 1) + k
f(1) = a•(h² - 2•h + 1) + k
f(1) - f(0) = 144 - 120 = 24 = -((2•h - 1)•a
24 = -((2•h - 1)•a
f(2) = 120 = a•(2 - h)² + k
f(2) - f(1) = -24 = -((2•h - 3)•a
(f(1) - f(0)) - (f(2) - f(1)) = 48 = -2•a
Therefore;
a = -24
24 = -((2•h - 1)•a
24 = -((2•h - 1)×(-24)
-1 = -((2•h - 1)
2•h - 1 = 1
h = 2/2 = 1
h = 1
120 = a•(2 - h)² + k
120 = (-24)•(2 - 1)² + k
k = 120 + 24 = 144
k = 144Which gives;
The vertex form is y = -24•(x-1)² + 144
From the vertex form, we have;
y = -24•(x-1)² + 144 = -24•(x²-2•t+1) + 144
y = -24•(x²-2•tlx+1)+ 144 = -24•x²+48•x - 24 + 144
y = -24•x²+48•x + 120
y = -24•x² + 48•x - 24 + 144 = -24•x²+ 48•x + 120
y = -24•x² + 48•x + 120
The height of the ball after 1.5 seconds is
y = -24×1.5² + 48×1.5 + 120 = 138
The height of the ball at t = 1.5 seconds is 138 feetLearn more about quadratic equations here:
