Determine whether the statement is always true, sometimes true, or never true. Give an example. (a) Both sides of an equation can be multiplied by the same number without changing the solution of the equation. (b) Both sides of an inequality can be multiplied by the same number without changing the solution set of the inequality. When do you put the brackets on the graph of a solution set
Answer:
(A) Always true
(B) Seldom true
Step-by-step explanation:
(A) Both sides of an equation can be multiplied by the same number without this action changing the solution of the equation.
Keyword here is "number".
Multiplying both sides of an equation by an equal quantity (same number) will result in same solution after solving for the unknown in the equation. This is because that numeric quantity can always be removed by dividing both sides of the equation by it or by a factor (or multiple) of it.
EXAMPLE:
For a linear equation, 4x - 6 = 15x
let's find the solution, in other words solve for the unknown value X.
4x - 15x = 6
-11x = 6
x = -6/11
Now multiply both sides of the equation by 3.
3(4x - 6) = 3(15x)
12x - 18 = 45x ___new equation
Solve for X
12x - 45x = 18
-33x = 18
x = -18/33
Reduce the fraction to its simplest form by looking for a number that can divide both numerator and denominator without remainder. In other words, think of a number that is a factor of 18 and a factor of 33.
That common factor or highest common factor (HCF) is 3.
Go ahead and reduce the fraction.
x will be reduced to -6/11
(B) Both sides of an inequality can seldom be multiplied by the same number, without such action changing the solution set of the equation.
Inequalities are more complex. Operational signs even change sometimes, in the course of finding the solution set of the inequality.
Sometimes, multiplying both sides of an inequality by a given numeric quantity will change its solution set and sometimes, it won't.

Answer:
52.65 percent
Step-by-step explanation:
Hi
Answer:
80.25%
Step-by-step explanation:
When you ask "What is 65 out of 81?" you want to know what percent 65 is out of 81.
Here are step-by-step instructions showing you how we calculated 65 out of 81 as a percentage:
The first step is to divide 65 by 81 to get the answer in decimal form
65 / 81 = 0.8025
Then, we multiplied the answer from the first step by one hundred to get the answer as a percentage:
0.8025 * 100 = 80.25%
Find the 9th term of the geometric sequence 6, 24, 96, ...
Answer:
1,572,864
Step-by-step explanation:
1. 6 x 4 = 24
2. 24 x 4 = 96
3. 96 x 4 = 384
4. 384 x 4 = 1,536
5. 1,536 x 4 = 6,144
6. 6,144 x 4 = 24,576
7. 24,576 x 4 = 98,304
8. 98,304 x 4 = 393,216
9. 393,216 x 4 = 1,572,864
The 9th term of the geometric sequence 6, 24, 96, ... is 393216
What is Sequence?A sequence is an enumerated collection of objects in which repetitions are allowed and order matters.
A geometric sequence is a sequence in which each term is found by multiplying the preceding term by the same value.
The given sequence 6, 24, 96, ...
six, twenty four, ninety six
a is first term=6
r is common ratio = 24/6=4
The nth term of Geometric sequence aₙ=a.rⁿ⁻¹
9th term a₉=6(4)⁸
=6(65536)
=393216
Hence, the 9th term of the geometric sequence 6, 24, 96, ... is 393216

Ishaan scored 72 on the exam.
Find the z-score for Ishaan's exam grade. Round to two decimal places.
Answer:
0.36
Step-by-step explanation:
Given that:
Mean = 70
Standard deviation = 5.5
score (x) = 72
Formular for obtaining Standardized score (Zscore) :
Zscore = [score (x) - mean] / standard deviation
Hence,
Zscore = (72 - 70) / 5.5
Zscore = 2/ 5.5
= 0.3636363
Zscore = 0.36 ( 2 decimal place)

A car travels 2 (5/8) miles 3 (1/2) minutes at a constant speed. How far did the car travel in 5 minutes?
Answer:
3.74 miles
Step-by-step explanation:
Given that,
Distance, [tex]d=2\dfrac{5}{8}\ \text{miles}=\dfrac{21}{8}\ \text{miles}[/tex]
Time, [tex]t=3\dfrac{1}{2}\ \min=\dfrac{7}{2}\ \min[/tex]
We need to find how much the car will travel in 5 minutes.
[tex]\dfrac{21}{8}\ miles = \dfrac{7}{2}\ min\\\\1\ min= \dfrac{21\times 2}{8\times 7}\\\\=0.75\ \text{miles}\\\\\text{In 5 minutes}, d = 0.75\times 5\\\\=3.75\ \text{miles}[/tex]
Hence, the car will cover 3.74 miles in 5 minutes.

9514 1404 393
Answer:
D
Step-by-step explanation:
The given line's equation is in slope-intercept form:
y = mx + b
where m = -4 is the slope, and b = -1 is the y-intercept.
The slope of the perpendicular line will be ...
-1/m = -1/(-4) = 1/4
You want the point-slope equation for the line, which is ...
y -k = m(x -h) . . . . line with slope m through point (h, k)
Your equation will have m=1/4, (h, k) = (-2, 7), so it will be ...
y -7 = 1/4(x +2)
