Solve the following absolute value equation for the unknown. Show all of your work for full credit. |-3h – 6| ≤ 3

ss7ja [257]

Answer:

$-3 \le h \le 1$ .

Step-by-step explanation:

Apply the property of absolute values: if $a \ge 0$ , then $|x| \le a \iff -a \le x \le a$ . By this property, $|- 3\, h - 6 | \le 3$ is equivalent to $-3 \le -3\, h - 6\le 3$ . That's the same as saying that $-3\, h - 6 \ge -3$ and $-3\, h - 6 \le 3$ .

Add $6$ to both sides of both inequalities:

$-3\, h \ge 3$ and $-3\, h \le 9$ .

Divide both sides of both inequalities by $(-3)$ . Note that because $-3 < 0$ , dividing both sides of an equality by this number will flip the direction of the inequality sign.

$-3\, h \ge 3$ would become $h \le -1$ .
$-3\, h \le 9$ would become $h \ge -3$ .

Both inequalities are supposed to be true. Combining the two inequalities to obtain:

$-3 \le h \le 1$ .

Given the graph of a scatterplot and a trend line, explain how you would find the equation of the trend line.

SpyIntel [72]

To find the equation of a trend line, It is important to find the X axis and Y axis, Once x axis and y axis is found if there is an association between x axis and y axis, We use linear equation to produce the trend line. Linear regression or algorithm called as OLS (Ordinary least square). Y= mx +c

y = dependent variable, x = independent variable , constant = c , m = y2-y1/x2-x1.

Step-by-step explanation:

Scatter plot is to find association of two different variable.
Trend line is the equation between xaxis and y axis.
Prediction is best way to form equation.
Linear regression y=mx +c
Equation helps in predictive modelling between next best form.
Y is a dependent variable or example sales.
X can be n number of variable involved in the association rule.
Linear regression is starting phase of data analysis.
C = constant there is a certain point, where system has been started.

Select the common ratio and the 4th term of the geometric series: 9, -6,4...

Blababa [14]

The given geometric sequence has the common ratio, r = -2/3, and the value of the 4th term, a₄ = -8/3.

A geometric sequence is a special series where every term is the product of the previous term and a common ratio.

The first term of a geometric sequence is represented as a, the common ratio as r, and the n-th term as aₙ, which is calculated as, aₙ = a.rⁿ⁻¹.

In the question, we are asked to find the common ratio and the 4th term of the geometric sequence, 9, -6, 4, ........

The first term of the sequence, a = 9.

The second term of the sequence, a₂ = -6.

By the formula of the n-th term, aₙ = a.rⁿ⁻¹, we can show that:

a₂ = a.r²⁻¹.

Substituting the values, we get:

-6 = 9(r²⁻¹),

or, r²⁻¹ = -6/9,

or, r = -2/3.

Thus, the common ratio of the given geometric sequence is -2/3.

The 4th term can be calculated using the formula of the n-th term, aₙ = a.rⁿ⁻¹ as:

a₄ = a.r⁴⁻¹ = a.r³.

Substituting the values, we get:

a₄ = 9(-2/3)³,

or, a₄ = 9.(-8/27),

or, a₄ = -8/3.

Thus, the 4th term of the given geometric sequence is -8/3.
