For the following exercises, solve each inequality and write the solution in interval notation.
30. 2| v − 7 | − 4 ≥ 42
Answer:
The solution to the inequality [tex]$2|v-7|-4 \geq 42$[/tex] in interval notation is given by [tex]$-16 \leq v \leq 30$[/tex].
Step-by-step explanation:
An absolute value inequality [tex]$2|v-7|-4 \geq 42$[/tex] is given.
It is required to solve the inequality and write the solution in interval form.
To write the solution, first solve the given absolute value inequality algebraically and then write it in interval notation.
Step 1 of 4
The given absolute value inequality is [tex]$2|v-7|-4 \geq 42$[/tex].
Add on both 4 sides,
[tex]$$\begin{aligned}&2|v-7|-4 \geq 42 \\&2|v-7|-4+4 \geq 42+4 \\&2|v-7| \geq 46\end{aligned}$$[/tex]
Step 2 of 4
Divide by 2 on both sides,
[tex]$$\begin{aligned}&\frac{2|v-7|}{2} \geq \frac{46}{2} \\&|v-7| \geq 23\end{aligned}$$[/tex]
The inequality can be written as [tex]$v-7 \leq 23$[/tex] and [tex]$v-7 \geq-23$[/tex]
Step 3 of 4
First solve the inequality, [tex]$v-7 \leq 23$[/tex].
Add 7 on both sides,
[tex]$$\begin{aligned}&v-7 \leq 23 \\&v-7+7 \leq 23+7 \\&v \leq 30\end{aligned}$$[/tex]
Step 4 of 4
Solve the inequality [tex]$v-7 \geq-23$[/tex].
Add 7 on both sides,
[tex]$$\begin{aligned}&v-7 \geq-23 \\&v-7+7 \geq-23+7 \\&v \geq-16\end{aligned}$$[/tex]
The solution of the inequality in interval notation is given by [tex]$-16 \leq v \leq 30$[/tex].
What is the equation of the line shown above?
Answer:
[tex]a.) y=\frac{1}{4} x+3[/tex]
Step-by-step explanation:
Any two points along the line are (4,4) and (0,3),
[tex]Gradient= \frac{4-3}{4-0}=\frac{1}{4}[/tex]
we know the y intercept is 3
Therefore equation of the line is : [tex]y=\frac{1}{4} x+3[/tex]
The vertex of the graph of f(x)=|X-3|+6 is located at
The vertex of the graph of f(x)= |x-3|+6 is located at (3, 6)
How to determine the vertex?The equation of the function is given as:
f(x) = |x - 3| + 6
The above function is an absolute value function.
An absolute value function is represented as:
f(x) = a|x - h| + k
Where:
Vertex = (h, k)
By comparison, we have:
Vertex = (3, 6)
Hence, the vertex of the graph of f(x)= |x-3|+6 is located at (3, 6)

Which set of ordered pairs has the same slope as the given set: (2,9) (1,12)?
The slope(m) of the given set is -3.
What is the slope of a pair of the ordered set?The slope(m) of a pair of the given ordered set is the change in the rise over the run. The rise is the y-axis while the run is the x-axis.
Mathematically;
[tex]\mathbf{Slope(m) = \dfrac{\Delta y}{ \Delta x}}[/tex]
[tex]\mathbf{Slope(m) = \dfrac{y_2-y_1}{x_2-x_1} }[/tex]
Here:
x_1 = 2y_1 = 9x_2 = 1y_2 = 12[tex]\mathbf{Slope(m) = \dfrac{12-9}{1-2} }[/tex]
[tex]\mathbf{Slope(m) = \dfrac{3}{-1} }[/tex]
Slope (m) = -3

write each polynomial in standard form. Then give the leading coefficient. You may need to combine like terms before writing the polynomial in standard form.
10-3x²+x^5 + 4x³
Step-by-step explanation:
To write a polynomial in standard form, put the degree that are the greatest first
So here it would be
[tex] {x}^{5} + 4 {x}^{3} - 3 {x}^{2} + 10[/tex]
Remember constant are numbers that you learned back in elementary,
Numbers like 10,90,4,1,0,-3 etc.
Remember that constant are basically represented like this
[tex]k \times {x}^{0} [/tex]
For example, 10 is represented like
[tex]10 \times {x}^{0} [/tex]
Since 0 is the smallest degree possible, for a polynomial, constants are the last term of a polynomial in standard form

The cost of a gallon of gas increased from $3.54 to $3.87 over the weekend. What is the percent increase for the cost of gas, rounded to the nearest whole percent?
Answer:
9%
Step-by-step explanation:
percent increase is calculated as
[tex]\frac{increase}{original}[/tex] × 100%
increase = $3.87 - $3.54 = $0.33 , then
% increase = [tex]\frac{0.33}{3.54}[/tex] × 100% ≈ 9% ( to the nearest whole percent )
Answer:
9 % (rounded to the nearest whole percent)
Step-by-step explanation:
the amount of increase:
3.87 - 3.54 = 0.33
Then
the percent increase for the cost of gas :
[tex]=\frac{0.33}{3.54} \times 100\\\\= 0.093220338983 \times 100\\\\=9.3220338983 \ \%[/tex]

424. House Paint April wants to paint the exterior of her house. One gallon of paint covers about 350 square feet, and the exterior of the house measures approximately 2000 square feet. How many gallons of paint will she have to buy?
Answer:
If the exterior of the house is 2000 square feet and each gallon of paint covers 350 square feet.
Then she needs to buy 6 gallons of paint.
Step-by-step explanation:
Dividing the total area by the area that each gallon of paint covers we get,
[tex]$\frac{2000}{350} \times \frac{50}{50}=\frac{40}{7}$$[/tex]
Now, performing long division we get,
[tex]$7\overset{5}{\overline{\left){\begin{align} & 40 \\ & \underline{35} \\ & \underline{05} \\ \end{align}}\right.}}$$[/tex]
She needs five gallons of paint fully and some amount of the sixth gallon because we get a remainder.
She can't buy paint in fraction, hence she has to buy 6 gallons of paint.

Durante una venta de liquidación, el Sr. Pablo, un profesor particular, compró un total de 12 libros de asesoría de Secundaria 4 y Secundaria 1 por S/82. El precio de un libro de asesoría de Secundaria 4 era de S/ 8 y el precio de un libro de asesoría de
Secundaria 1 era de S/ 6. Que el número de los libros de asesoría de Secundaria 1 comprados sea “k”.
a) Expresa el número de libros de asesoría de Secundaria 4 comprados en términos de “k”.
b) Forma una ecuación en “k' y resuélvela, calculando la cantidad de libros de cada tipo que compró el Sr.Pablo
Resolviendo un sistema de ecuaciones, vemos que se venden 6 libros de secundaria 4 y 6 libros de secundaria 1.
¿Como escribir un sistema de ecuaciones?
Primero definimos dos variables:
x = numero de libros de secundaria 4 vendidos.k = número de libros de secundaria 1 vendidos.Sabemos que se venden 12 libros en total, entonces:
x + k = 12
Tambien sabemos que se recauda un total de $82, entonces:
x*$8 + k*$6 = $82
Entonces tenemos dos ecuaciones.
a) Usando la primer ecuacion, podemos aislar x para tener:
x = 12 - k
b) Ahora podemos reemplazar eso en la otra ecuación para solucionar el sistema.
(12 - k)*$8 + k*$6 = $82
$96 - $2*x = $82
$2*x = $12
x = $12/$2 = 6
Es decir se venden 6 libros de secundaria 4, y como se venden 12 libros en total, los otros 6 libros vendidos son de secundaria 1.
