Answer:
x = 1/2 and
x = -15/2
Step-by-step explanation:
First, get the absolute value alone on one side if the equation.
2 |2x + 7 | = 16
Divide both sides by 2.
| 2x + 7 | = 8
Once the absolute value sign is by itself, you will separate the equation into two separate equations.
2x+7=8 and 2x+7=-8
Solve these two equations separately and get two solutions.
2x + 7 = 8
Subtract 7.
2x = 1
Divide by 2.
x = 1/2 Here is one solution.
2x + 7 = -8
Subtract 7.
2x = -15
Divide by 2.
x = -15/2 Here is a second solution.
Answer:
x = - [tex]\frac{15}{2}[/tex] , x = [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
2 | 2x + 7 | = 16 ( divide both sides by 2 )
| 2x + 7 | = 8
the absolute value function always gives a positive result, but the expression inside can be positive or negative , that is
2x + 7 = 8 ( subtract 7 from both sides )
2x = 1 ( divide both sides by 2 )
x = [tex]\frac{1}{2}[/tex]
or
- (2x + 7) = 8
- 2x - 7 = 8 ( add 7 to both sides )
- 2x = 15 ( divide both sides by - 2 )
x = - [tex]\frac{15}{2}[/tex]
As a check
substitute these values into the left side and if equal to the right side then they are a solution
x = [tex]\frac{1}{2}[/tex]
2 | 2([tex]\frac{1}{2}[/tex] ) + 7 | = 2 | 1 + 7 | = 2 | 8 | = 16 = right side
x = - [tex]\frac{15}{2}[/tex]
2 | 2(- [tex]\frac{15}{2}[/tex] ) + 7 | = 2 | - 15 + 7 | = 2 | - 8 | = 2 | 8 | = 16 = right side
then x = - [tex]\frac{15}{2}[/tex] and x = [tex]\frac{1}{2}[/tex] are the solutions
la tarifa de un recorrido de taxi es de 7.25 de cargo fijo y de 7 por cada km recorrido determina la ecuación si p corresponde al valor del pago por x km recorridos
The equation that illustrates the amount to be paid for the number of kilometers will be 7.25 + 7x.
How to illustrate the information?Fixed rate for taxi = 7.25
Additional charges per kilometers = 7
Number of kilometers = x
Therefore, the equation that illustrates the amount to be paid for the number of kilometers will be:
= 7.25 + (7 × x)
= 7.25 + 7x
Therefore, the equation is 7.25 + 7x.

Explain the properties used to solve inequalities and how they are different from properties of equality
The major difference between inequality and equality is that equality represents a particular value(s) while inequality represents a range of values that are in a specific direction.
What are the properties that are used to solve inequalities?This must be noted when solving questions on equality and inequality.
For example:
x = a means that the value of x is a. It represents a particular value which is a
x < a represents all the values that are less than a.
x ≤ a represents values from a and below.
x > a represents all the values that are greater than a
x ≥ a means that the values of x are greater than or equal to a.
From the examples given above, it is obvious that a change in the direction of the inequality sign changes the values of the data represented by the inequality.

7) In the given figure, PQR is an equilateral triangle with coordinates of Q and
R as (-2, 0) and (2, 0) respectively. Find the coordinates of the vertex P.
The coordinates of the vertex P is calculated as (0,2√3).
What is defined as the distance formula?The distances among two points as a characteristic of their coordinates are given by an algebraic expression (like coordinate system).
The Pythagorean theorem is used to derive distance formulae for points in rectangular coordinates in 2- and three-dimensional Euclidean space.Because it has a starting and ending point, a line segment can be graphed in both two-dimensional and three-dimensional coordinate planes.Because of the two-dimensional coordinate plane, the starting and stopping points can also be marked as two-dimensional coordinates (x₁, y₁) and (x₂, y₂), culminating in the distance formula as: d = √(x₂ - x₁)² + (y₂ - y₁)².Now, according to the given question;
The coordinates of the points Q and R is given as;
Q and R as (-2, 0) and (2, 0).
Now, as the all three points P,Q and R forms the equilateral triangle. Then, the distance of each side or the distance between two consecutive points are equal.
Calculate the distances between the points;
Distance between Q and R;QR = √(2 + 2)² + (0 - 0)²
QR = 4
Distance between Q and P;Let the coordinated of P be (x, y);
Then,
QP = √(x + 2)² + (y + 0)²
QP = QR = 4
4 = √(x + 2)² + (y)² ........(equation 1)
Distance between R and P;RP = √(x - 2)² + (y + 0)²
RP = QR = 4
4 = √(x - 2)² + (y)² ........(equation 2)
Equating equation 1 and 2.
√(x + 2)² + (y)² = √(x - 2)² + (y)²
Squaring both side;
(x + 2)² + (y)² = (x - 2)² + (y)²
x² + 4 - 4x + y² = x² + 4 - 4x + y²
Simplifying the equation;
x = 0.
Put the value of x in equation 1;
4 = √(x + 2)² + (y)²
y = 2√3.
Therefore, the coordinates of the point P are found to be (0, 2√3).

If h(x)= -5/6x + 7/8 find the following values. Simplify your answer.
H(3)=
H(4)=
H(-1/2)=
If [tex]h(x)=\frac{-5}{6} x+\frac{7}{8}[/tex] then the value of h(3) = -13/8 , h(4) = -59/24 , h(-1/2) = 31/24 .
In the question , the equation is given as
[tex]h(x)=\frac{-5}{6} x+\frac{7}{8}[/tex] ....(i)
Part(a)
To find the value of h(3)
we substitute the value of x=3 .
On substituting the value of x=3 in equation (i),
we get ,
h(3) = (-5/6)3+7/8
= -15/6+7/8
taking LCM of 6 and 8 as 24, we get
= -60/24 + 21/24
= (-60+21)/24
= -39/24
Writing in the simplest form we get
= -13/8
so, the value of h(3)= -13/8 .
Part(b)
for h(4) ,we substitute the value of x=4 .
On substituting the value of x=4 in equation (i) ,
we get ,
h(4) = (-5/6)4+7/8
= -20/6+7/8
taking LCM of 6 and 8 as 24, we get
= -80/24 + 21/24
= (-80+21)/24
= -59/24
so , the value of h(4)= -59/24 .
Part(c)
for h(-1/2) ,we substitute the value of x as -1/2 .
On substituting the value of x = -1/2 in equation (i) ,
we get ,
[tex]h(\frac{-1}{2} )=\frac{-5}{6} *\frac{-1}{2} +\frac{7}{8}[/tex]
= 5/12 +7/8
taking LCM of 12 and 8 as 24, we get
= 10/24 + 21/24
= (10+21)/24
= 31/24
so , the value of h(-1/2)= 31/24 .
Therefore , if h(x) = (-5/6)x+7/8 the the value of h(3)= -13/8 , h(4)= -59/24 and h(-1/2)= 31/24 .

How to determine the statementFrom the information given, we have that;
The linear equation is ;
-2x + 3 = 6
Let's solve for x
First, collect like terms
-2x = 6 - 3
-2x = 3
Divide both sides by - 2
x = 3/ -2
The linear inequality is;
-2x + 3 < 6
collect like terms
-2x < 6 - 3
Make 'x' the subject by dividing both sides by -2
-2x/ -2 = 3/ -2
x = 3/ -2
We can see that the linear equation and the linear inequality have the same solution and steps.
