The difference of the polynomials, (p² + p - 8) - (-4p² - p + 3), is: D. 5p² + 2p - 11.
How to Find the Difference of Two Polynomials?To find the difference of two polynomials, group like terms together after opening up the parentheses, then combine the like terms together.
Given the polynomials:
(p² + p - 8) - (-4p² - p + 3)
Apply the distributive property to eliminate the parentheses
p² + p - 8 -1(-4p²) -1(-p) -1(3)
p² + p - 8 + 4p² + p - 3
Group like terms
p² + 4p² + p + p - 8 - 3
Combine like terms
5p² + 2p - 11
Thus, the difference of the polynomials, (p² + p - 8) - (-4p² - p + 3), is: D. 5p² + 2p - 11.

write an equation for the difference of 7 and a number is 18
Answers
Then the 'difference of a number and 7' can be written as: n -7
If twice this equals 18 we can express this with the equation: 2(n-7) = 18
Solve the equation for n:
2(n-7) = 18
n - 7 = 9 <-- divide both sides by 2
+7 +7
n = 16 <-- Add 7 on both sides for answer
CHECK by plugging in 16 to the original statement. "Twice the difference of 16 and 7 is 18"
2 (16 -7) = 2 (9) = 18 ! Therefore our solution is correct

Write an equation of the line through each pair of points in slope-intercept form.
(-1,-4) and (3,-4)
Answers
The equation of line is y = -4
Given the points:
(x₁, y₁) = (-1, -4)
(x₂, y₂) = ( 3, -4)
The slope-intercept form:
y = mx + b
Where, m is the slope and b is the y-intercept, that is (0, b)
The formula for slope:
m = (y₂ – y₁) / (x₂ – x₁)
We have given
x₁ = -1
x₂ = 3
y₁ = -4
y₂ = -4
So,
m = (-4 – (-4)) / (3 – (-1)) = (-4 + 4) / (3 + 1) = 0/4 = 0
Therefore we have the equation of the line as:
y = mx + b
-4 = 0(x) + b
-4 = 0 + b
b = -4
Therefore, the equation of line y = -4

Write an absolute value equation to represent the maximum and minimum weight for the bags of sand. b. Solve the equation and interpret the result.
Answers
From the situation described, we have that:
a. The absolute value equation is: |w - 35| = 8.
b. The solutions are w = 27 and w = 43, meaning that the minimum weight is of 27 pounds and the maximum weight is of 43 pounds.
What is the missing information?A home improvement store sells bags of sand, which are labeled as weighing 35 pounds. The equipment used to package the sand produces bags with a weight that is within 8 pounds of the labeled weight.
What is the absolute value function?The absolute function is defined by:
|x| = x, x ≥ 0.|x| = -x, x < 0.It measures the distance of a point x to the origin, hence, for example, |-2| = |2| = 0.
For this problem, the difference between the weight w and 35 pounds is of 8 pounds, hence the equation is:
|w - 35| = 8.
From the definition, the solutions are given as follows:
w - 35 = -8 -> w = 27.w - 35 = 8 -> w = 43.The solutions are w = 27 and w = 43, meaning that the minimum weight is of 27 pounds and the maximum weight is of 43 pounds.

5. The coordinates of X are (a - 5, -2a) . The coordinates of Y are (a + 1, 2a) . If the distance between X and Y is 10, find the value of a.
Answers
Applying the distance formula, the value of a is 2 or -2.
What is the Distance Formula?The distance formula is:
d = [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex].
Given the following:
d = XY = 10 units
X(a - 5, -2a) = (x1, y1)
Y(a + 1, 2a) = (x2, y2)
Plug in the values into the distance formula
10 = √[((a + 1) - (a - 5))² + (2a - (-2a))²]
10 = √[(a + 1 - a + 5)² + (2a + 2a)²]
10 = √(6² + (4a)²)
10 = √(36 + 16a²)
10² = 36 + 16a²
100 = 36 + 16a²
0 = -100 + 36 + 16a²
0 = 16a² - 64
16a² - 64 = 0
Factorize
16(a² - 4) = 0
16(a - 2)(a + 2) = 0
a = 2 or a = -2
Therefore, applying the distance formula, the value of a is 2 or -2.

Let h(x) be the reflection of f(x)=3 x+3 in the x -axis. What is a function rule for h(x) ?
Answers
The function rule for h(x) = -3x -3.
In mathematics, functions can be manipulated algebraically to obtain graphs of functions through certain transformations. Such transformations are reflections of the x-axis or the y-axis. To flip a function f(x) on the x-axis, multiply the whole function by a negative value to get -f(x), and to flip a function f(x) on the y axis, f(-x ), specify the x variable with a negative value. If it is reflected around the y-axis, it will stay the same, which gives h(x) = 3x + 3. Flipping around the x-axis (assuming y = 0) has the y-axis as the axis of symmetry, but it is concave down.
The function rule around the x-axis gives a complementary sign of the value of the function, so
h(x) =-3x-3 will be reflection of f(x) =3x+3

A builder is framing windows of a new with lumber each side of the window must be one piece of lumber. The windows should be three feet high and three feet wide. How many windows can be framed with three 10-foot long pieces of lumber
Answers
The number of windows which can be framed with three 10-foot long pieces of lumber given the dimensions of the windows is; two and a half.
What is the number of windows that can be made using the lumbers given the dimensions of the windows?It follows from the task content that the number of windows that can be made given the dimensions of the windows be determined.
On this note, it follows that since the windows are 3 feet high and 3 feet width, the perimeter of each window(square shaped) covered by lumber is;
P = 4s
P = 4 × 3
P = 12 feet.
Hence, each window requires 12 feet of lumber.
However, since the builder has only three 10-foot long pieces of lumber which is equivalent to; 3 × 10 = 30 feet worth.
The number of windows that can be made is;
= 30/12
= 2.5.
Ultimately, only 2 and a half windows can be framed from the three 10-foot long pieces of lumber.

What is the mass of gasoline (density = 0.680 g/cm3 ) in a 94.6 l gasoline tank?
Answers
A 94.6 L gasoline with a density of 0.680 g/cm^3 has a mass of 64328 g.
Density is defined as the ratio between the mass of a substance and the volume it occupies. Denoted by ρ, density is mass per unit volume and the formula is given below:
ρ = mass / volume
Converting first the volume from L to cm^3.
1 L = 1000 cm^3
94.6 L = 94.6(1000 cm^3)
94.6 L = 94,600 cm^3
Given the density of the gasoline and its volume, solve for the mass of the gasoline using the formula for the density.
ρ = mass / volume
0.680 g/cm^3 = mass / 94,600 cm^3
mass = 0.680 g/cm^3 (94,600 cm^3)

f(x) = f(x) + k
This is a translation transformation that shifts the original function f(x) either k units up or k units down. If k is more than 0 then k shifts up. If k is less than 0 then k shifts down.
Here, k = -5<0
