1. Any linear inequality in one variable has a single-value solution like an equation.
True or False
2. A value is a solution to an inequality if we can substitute it into the inequality and get a true statement.
True or False
Answer:
1. false
2. true
Step-by-step explanation:
I hope it's correct
The statement a) false and b) true are the correct answers.
What is an inequality?An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. It is the condition of being unequal.
For the given situation,
An inequality which involves a linear function is a linear inequality. It looks like a linear equation, except that the ‘=’ sign is replaced by an inequality sign, called linear inequations.
a) Any linear inequality in one variable has a single-value solution like an equation.
A solution to a linear inequality is a real number that will produce a true statement when substituted for the variable.
Linear inequalities have either infinitely many solutions or no solution.
Thus the statement is false.
b) A value is a solution to an inequality if we can substitute it into the inequality and get a true statement.
Any solution of an inequality in one variable is a value of the variable.
Thus the statement is true.
Hence we can conclude that for the statement a) false and b) true are the correct answers.

HURRY QUICKLY Ashley is preparing for a horse riding competition. She has trained her horse for 4 hours and has completed 172 rounds. At what rate has Ashley ridden her horse in rounds per hour?
A.
42 rounds per hour
B.
44 rounds per hour
C.
45 rounds per hour
D.
43 rounds per hour
Step-by-step explanation:
C. 45 rounds per hour. is the answer
Answer:
D (43 Rounds Per Hour)
Step-by-step explanation:
Ashley has completed 172 rounds and trained her horse for 4 hours. Supposing she riding is training her horse, we can divide 172 by 4, showing how much rounds is completed in an hour. If you think about it, dividing by four is making it four times less. And since Ashley have ridden it for four hours, dividing it by four makes one hour. Now, for the math, we do 172/4 (172 divided by 4), and get 43, which is D.

A) 1
B) 2
C) 4.

Answer: A) 1
Since z(3) = 4, w(z(3)) = w(4)Since w(4) = 1, w(z(3)) = w(4) = 1Erica drives 25 miles south, and then drives east. After a while, it is determined that she's 60 miles (diagonally) from where she started. How far east did she drive? (HINT: draw a rough sketch!)
The distance she drove east from the starting point is 54.54 miles.
The given parameters include;
initial displacement of Erica, d₁ = 25 miles south
final position of Erica, d₂ = 60 miles east
The displacement of Erica from the initial position as shown in the diagram is calculated as;
Apply Pythagoras theorem, to solve for x;
x² = d₂² - d₁²
x² = 60² - 25²
x² = 2975
x = √2975
x = 54.54 miles
Therefore, the distance she drove east from the starting point is 54.54 miles.

Simplify the following expression and evaluate for x=36
b
0.02(1.4x - 300)-0.2(2.4x+10)+0.552x
answer:
Answer:
0.028x-6-0.48x-2+0.552x
(0.028-0.48+0.552)x-6-2
0.1x-8
The simplified expression, when evaluated for x=36, is -4.4, when following expression and evaluate for x=36 b= 0.02(1.4x - 300)-0.2(2.4x+10)+0.552x
To simplify the expression and evaluate it for x=36, let's break it down step by step:
0.02(1.4x - 300) - 0.2(2.4x + 10) + 0.552x
First, let's simplify the terms within each set of parentheses:
0.02 * (1.4 * 36 - 300) - 0.2 * (2.4 * 36 + 10) + 0.552 * 36
Next, perform the multiplications and additions/subtractions within each set of parentheses:
0.02 * (50.4 - 300) - 0.2 * (86.4 + 10) + 0.552 * 36
0.02 * (-249.6) - 0.2 * (96.4) + 19.872
Now, evaluate the remaining multiplications:
-4.992 - 19.28 + 19.872
Finally, perform the additions and subtractions:
-4.992 - 19.28 + 19.872 = -4.4
Therefore, the simplified expression, when evaluated for x=36, is -4.4.

Answer:
y = 5/3x +8
Step-by-step explanation:
The slope of the perpendicular line is the opposite reciprocal of the slope of the given line. The given slope is -3/5, so the perpendicular slope is ...
-1/(-3/5) = 5/3
That and the given y-intercept can be put into the slope-intercept equation ...
y = mx + b . . . . . line of slope m and y-intercept b
y = 5/3x + 8

How do I solve this
Answer:
x = -1 y = 3
Step-by-step explanation:
x = 2y-7
2x + 3y = 7
Substitute x =2y-7 in 2y + 3y = 7
2(2y-7) + 3y = 7
4y-14+3y = 7
7y - 14 = 7
7y = 7 + 14
7y = 21
7y/7 = 21/7
y = 3
Substitute 3 for y in x = 2y-7
x = 2(3) - 7
x = 6 -7
x = -1

What is the slope of the line below is -5. Which of the following is the point-slope form of the line?
Answer:
[see below]
Step-by-step explanation:
Point slope form is:

(x1, y1) - a point
m - slope
We are given the point of (2, -7), and the slope of -5.
[tex]y-y_1=m(x-x_1)\rightarrow y-(-7)=-5(x-2)\rightarrow\boxed{y+7=-5(x-2)}[/tex]

Find the equation of the line that is parallel
to the line y = -5x - 9 and passes
through the point (-4,-9) Write the
equation in slope-intercept form.
A parallel line would contain the same slope and have a different y-intercept.
Using the slope of the original line you would start with:
Y = -5x + b, where b is the new y-intercept.
Using the given point replace x and y and solve for b:
-9 = -5(-4) + b
Simplify:
-9 = 20 + b
Subtract 20 from both sides
-29 = b
Now replace b in the equation to get:
Y = -5x -29
