Other than replacing the equal sign with some sort of inequality sign, what is the one big difference we need to keep in mind when solving a linear inequality?
Step-by-step explanation:
In response to this question,
When solving a linear equality, one difference that we must keep in mind other than replacement of = sign with some equality sign is that when we do multiplication or division with a negative number, we are then required as a must to change the direction of the inequality sign.

5) Adam bought 5 DVDs that cost $12.95
each. How much did Adam spend
before taxes?
Answer:
$64.75
Step-by-step explanation:
You can add $12.95 five times:
$12.95 +12.95 +12.95 +12.95 +12.95 = spending
but it is probably easier to use multiplication:
5 × $12.95 = spending = $64.75
Adam spent $64.75.
Answer:
64.75
Step-by-step explanation:
So you have 5 DVDs bought and 12.95 for each.
12.95 x 5
12.95 + 12.95 = 25.90
25.90 + 12.95 = 38.85
38.85 + 12.95 = 51.80
51.80 + 12.95 = 64.75
So your answer is $64.75

What is the slope of a line that is perpendicular to the graphed line?
Answer:
2
Step-by-step explanation:
To find the slope of the graphed line, you take two points. I have chosen (0, 4) and (8, 0)
The formula of a slope is (y value of second point [tex]-y[/tex] value of first point) divided by (x value of second point [tex]-x[/tex] value of first point):
[tex]\frac{0-4}{8-0} =-\frac{1}{2}[/tex]

Solve for M
D=m/v
Show your work
Answer: m=vD
Step-by-step explanation:
To get m alone, you want to use algebraic properties.
[tex]D=\frac{m}{v}[/tex] [multiply both sides by v]
[tex]m=vD[/tex]
Now that we have mass alone, we know that m=vD.

Find the distance between the points (3,6) and (10,4). The answer must be a whole number or a fully simplified radical expression do not round up
Answer:
The answer is
[tex]\sqrt{53} \: \: \: units[/tex]Step-by-step explanation:
The distance between two points can be found by using the formula
[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(3,6) and (10,4).
The distance is
[tex]d = \sqrt{ ({3 - 10})^{2} + ({6 - 4})^{2} } \\ = \sqrt{ ({ - 7})^{2} + {2}^{2} } \\ = \sqrt{49 + 4} \\ = \sqrt{53} \: \: \: \: \: \: \: \: [/tex]We have the final answer as
[tex] \sqrt{53} \: \: \: units[/tex]Hope this helps you

To solve you must work backward, she has 8 jars of 13 pieces so first do
8*13=104, she currently has 104 pieces. Then add back the five she ate and you get 109
Answer:
109
Step-by-step explanation:
If Anita split the candy into 8 jars, each jar containing 13 pieces of candy, you need to multiply 8 x 13 to get the amount of candy she had after eating the 5 pieces. 8 x 13 is 104. Then, you need to add the 5 pieces of candy she ate before splitting the candy into jars, meaning you must add 5 to 104. 5 + 104 = 109.
The dashed triangle is a dilation image of the solid triangle. What is the scale factor? A. 1/4 B. 1/2 C. 2/3 D. 2
Answer:
I am not good in maths but I think it is
A 1/4
A model's scale ratio is the ratio of linear dimensions. The scale factor of the triangle is (1/2).
What is the scale ratio?A model's scale ratio is the proportionate ratio of a linear dimension of the model to the equivalent characteristic of the original.
The scale ratio of the triangle can be found by taking the ratio of any one side of the dashed triangle to the solid triangle. Therefore, the scale ratio will be,
[tex]\rm Scale\ ratio = \dfrac{\text{Length of the dashed line}}{\text{Length of the solid line}}\\\\ Scale\ ratio = \dfrac{2}{4} = \dfrac{1}{2}[/tex]
Hence, the scale factor of the triangle is (1/2).

ali is writing a computer program. last week he wrote 25 lines of code each day for 5 days. this week her wrote 42 more twice the number of lines of code he wrote last week. how many lines of code he wrote altogether for his computer program
Answer:
292 lines of code
Step-by-step explanation:
1.) Multiply. 25 times 5 = 125
2.) Multiply previous answer by 2 (because he wrote twice as much). 125 times 2 = 250
3.) Add 42 to previous answer. 250 + 42 = 292

Train A and train B stops at Swindon at 10:30 . Train A stops every twelve minutes and train B stops every 14 Mins , when do they both stop at Swindon again ?
Answer: at 11:54
Step-by-step explanation:
Let's define the 10:30 as our t = 0 min.
We know that Train A stops every 12 mins, and Train B stops every 14 mins, they will stop at the same time in the least common multiple of 12 and 14.
To find the least common multiple of two numbers, we must do:
LCM(a,b) = a*b/GCD(a,b)
Where GCD(a, b) is the greatest common divisor of a and b.
In this case the only common divisior of 12 and 14 is 2.
So we have:
LCM(12, 14) = 12*14/2 = 84.
Then the both trains will stop 84 minutes after 10:30
one hour has 60 mins, so we can write 84 minutes as:
1 hour and 24 minutes = 1:24
Then they will stop at the same time at 10:30 + 1:24 = 11:54

Find the real roots of
[tex] \frac{18}{ {x}^{4} } + \frac{1}{ {x}^{2} } = 4[/tex]
see the photos above given
Answer:
[tex]$x^2=\frac{9}{4} \implies x=\pm \frac{3}{2} $[/tex]
[tex]$x^2=-2 \implies x=\pm\sqrt{-2} \implies x=\pm\sqrt{2i} $[/tex]
The solutions are
[tex]$\{-\frac{3}{2},\frac{3}{2}, -\sqrt{2i}, \sqrt{2i} \}$[/tex]
The Real roots are
[tex]$\{-\frac{3}{2},\frac{3}{2}\}$[/tex]
Step-by-step explanation:
[tex]$\frac{18}{x^4} +\frac{1}{x^2}=4$[/tex]
Multiply both sides by [tex]x^4[/tex]
[tex]$x^4\frac{18}{x^4} +x^4\frac{1}{x^2}=4\cdot x^4$[/tex]
[tex]$18+x^2=4x^4$[/tex]
[tex]4x^4-x^2-18=0[/tex]
Substitute [tex]x^2=t[/tex]
[tex]4t^2-t-18=0[/tex]
Solving the quadratic equation using the quadratic formula:
[tex]$t=\frac{-(-1)\pm \sqrt{(-1)^2-4\cdot 4(-18)}}{2\cdot 4}$[/tex]
[tex]$t=\frac{1\pm \sqrt{289}}{8}$[/tex]
[tex]$t=\frac{1\pm 17}{8}$[/tex]
[tex]$t_1=\frac{9}{4}$[/tex]
[tex]t_2=-2[/tex]
Now we have to solve for [tex]x^2=t[/tex]
[tex]$x^2=\frac{9}{4} \implies x=\pm \frac{3}{2} $[/tex]
[tex]$x^2=-2 \implies x=\pm\sqrt{-2} \implies x=\pm\sqrt{2i} $[/tex]
