What is equation?Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S.
There are different parts of an equation which include coefficients, variables, operators, constants, terms, expressions, and an equal to sign. When we write an equation, it is mandatory to have an "=" sign, and terms on both sides. Both sides should be equal to each other. An equation doesn't need to have multiple terms on either of the sides, having variables, and operators. An equation can be formed without these as well, for example, 5 + 10 = 15.

Evaluate the following function for f(x)=−3 f(x)=2x+5
Answer:
x = -4
Step-by-step explanation:
Step 1: Write out given
f(x) = -3
f(x) = 2x + 5
Step 2: Substitute f(x)
-3 = 2x + 5
Step 3: Solve for x
-3 - 5 = 2x + 5 - 5
-8 = 2x
-8/2 = 2x/2
-4 = x
Answer:
x = - 4Step-by-step explanation:
f(x)=2x+5
To find f(x)=−3 equate f(x) to - 3 and evaluate
That's
2x + 5 = - 3
Subtract 5 from both sides
That's
2x + 5 - 5 = - 3 - 5
2x = - 8
Divide both sides by 2
[tex] \frac{2x}{2} = - \frac{8}{2} [/tex]
We have the final answer as
x = - 4Hope this helps you

Answer:
C
Step-by-step explanation:
So we have the following sequence:
-7, -3, 1, 5...
As given, the (direct) formula for any arithmetic sequence is:
[tex]a_n=a_1+d(n-1)[/tex]
Where aₙ is the value of the nth term, a₁ is the value of the first term, and d is the common difference.
From the sequence, we can see that the initial/first term is -7. Thus, a₁ is -7.
And we can see that each subsequent number if 4 greater than the previous one. Thus, the common difference is +4.
Therefore, plugging these into our equation, we have:
[tex]a_n=-7+4(n-1)[/tex]
The answer is C.

Select all of the following scenarios below that contain nonbiased samples.
Select all that apply:
✓ To estimate the political party distribution of residents in his state, Frank collects data from a large group of
randomly selected residents of his city.
✓ To estimate the mean number of classes that students take at his university, Samuel collects data from a
randomly selected proportionate number of students from each grade level.
David wants to estimate the mean grade point average of students at his school. He collects data by recording the
grade point average of every 25th student on the list of students after a randomly selected first student
Helen wants to estimate the male to female ratio of the residents of her city. She collects data by recording the sex
of every 50th resident after selecting a random starting point on a list of residents,
Answer:
b.) To estimate the mean number of classes that students take at his university, Samuel collects data from a randomly selected proportionate number of students from each grade level.
c.) David wants to estimate the mean grade point average of students at his school. He collects data by recording the grade point average of every 25th student on the list of students after a randomly selected first student.
d.) Helen wants to estimate the male to female ratio of the residents of her city. She collects data by recording the sex of every 50th resident after selecting a random starting point on a list of residents.
Why? Because a sample is only biased if some individuals of the population are more or less likely to be chosen than others.
The sample from choice B isn't biased because every student has the same opportunity of being selected. It's the same predicament with choice C; it's also non-biased because again, each student has a chance of being in it, there is no preference.
And finally, the sample from option D is non-biased, because every resident that is being selected has an equally fair chance of being selected at random.
Hope this helps ;)

Answer to 6: 0
Step-by-step explanation:
(4+5 Explanation):
We can start to imagine the graph of [tex]y=|x|[/tex] in our head.
If we have a positive value of x, then y will be equal to x.
If we have a negative value of x, then y will be the opposite of x (since the absolute value of a negative is a positive).
This means that the graph will look a bit like this, changing at the point (0,0).
\/, it would look like a downward facing arrow. This means the vertex is at (0,0).

The dimension of the rectangle prism show are given in centimeters 4 cm 3 cm 1.4 cm what is the volume of the rectangular prism in the cubic centimeter
Answer:
16.8 cubic centimeter
Step-by-step explanation:
Dimensions of rectangular prism are:
[tex]4\ cm, 3\ cm , 1.4\ cm[/tex]
To find:
The volume of rectangular prism in cubic cm ?
Solution:
The formula for volume of prism is given as:
[tex]V=l\times w\times h[/tex]
Where [tex]l[/tex] is the length of rectangular prism
[tex]w[/tex] is the width of rectangular prism
[tex]h[/tex] is the height of rectangular prism
Here we are given the three dimensions of prism as:
Length, [tex]l[/tex] = 4 cm
Width, [tex]w[/tex] = 3 cm
Height, [tex]h[/tex] = 1.4 cm
Putting the values in formula for volume:
[tex]V=4\times 3\times 1.4\\\Rightarrow \bold{V =16.8\ cm^3}[/tex]
So, volume is 16.8 cubic centimeter.
Answer:
16.8
Step-by-step explanation
(4 cm times 3 cm) = 12 cm times 1.4 = 16.8

Bernard's bird feeder holds 4 1/2 cups of birdseed. Bernard is filling the bird feeder with a scoop that holds 9/10 of a cup. How many scoops of birdseed will Bernard put into the feeder? Write your answer as a fraction or as a whole or mixed number.
Answer:
5 scoops
Step-by-step explanation:
Given
[tex]Feeder = 4\frac{1}{2}[/tex]
[tex]Scoop = \frac{9}{10}[/tex]
Required
Determine the number of scoop in a feeder
To do this, we simply divide the size of the feeder by the size of the scoop as follows;
[tex]Number = \frac{Feeder}{Scoop}[/tex]
[tex]Number = 4\frac{1}{2}/\frac{9}{10}[/tex]
Convert Fractions to improper
[tex]Number = \frac{9}{2}/\frac{9}{10}[/tex]
[tex]Number = \frac{9}{2}*\frac{10}{9}[/tex]
[tex]Number = \frac{9 * 10}{2 * 9}[/tex]
[tex]Number = \frac{90}{18}[/tex]
[tex]Number = 5[/tex]
Hence, there are 5 scoops in a feeder

Solve each system of inequalties by graphing.
y< 3x+2
y<_-2x+1
↑ the second equation is y smaller than or equal to but i wont let me type that so :) PLZ help! ty!!♡
Start by graphing each line.
• Because the first inequality is smaller than, it will have a dotted (- - -) line.
• Because the second inequality is smaller than or equal to, it will have a solid line (---).
Then, plug in points to see where your shading will go. If the statement is true (x = x), you will shade that area along the line.
[tex]y < 3x + 2[/tex]
[tex](0) < 3(0) + 2[/tex]
[tex]0 < 2[/tex]
0 is less than 2.
Do the same step for the other equation. Your solution to the problem is any point that lies between the shading from both inequalities (where the blue and red meet).
