Step-by-step explanation:
Hey there!!
To solve this type of question, use these steps.
Find these 1st equation by using one point formula of point.After this from equation 2 find slope, by comparing it with y= mx + c if it is in slope intercept form. Then, as per the conditions of parallel lines, use m1=m2, then put the value of m1 in equation 1st.Then simplify them.So, let's work with these steps.
Now,
The equation of a st.line passing through point (2,1) is,
[tex](y - y1) = m1(x - x1)[/tex]
Put all values.
[tex](y - 1) = m1(x - 2)[/tex]
It is the 1st equation.
Another equation is,
y = -2x -3.......(ii)
Comparing the equation with y = mx+c.
Therefore, from equation (ii)
m2 = -2
Now, as per condition of parallel lines,
m1=m2= -2
Putting the value of m1 in equation 1st.
[tex](y - 1) = - 2(x - 2)[/tex]
y - 1 = -2x + 4
y = -2x +5.
Therefore, the equation is y = -2x +5.

When you add a positive number and a negative number, how can you tell whether the sum will be positive or negative? A. The sum will always be negative. B. The sum will always be positive. C. The sum will have a sign of the addend with the lesser absolute value. D. The sum will have the sign of the addend with the greater absolute value.
Answer:
Its C
Step-by-step explanation:
The sign of the resultant value will depend upon added values and the sum will have the sign of the addend with the lesser absolute value so the correct option will be (C).
What is summation?A summation, also abbreviated as a sum, is the outcome of adding two or more numbers or quantities. Here are always an integer number of terms in a summation. There could be only two terms, but there could be one hundred, thousand, or a million. There are summations with an infinite set of parameters.
In other words, the summation is the addition or subtraction of any two or more terms. As a result, we have a new result that may be large or little, depending on the quantity.
In given question
Let's suppose we add +5 + (-7) = -2 so here the sign is negative because the 5 is greater than the -7 so it is clear by this example that the sign of the addend with the lesser absolute value.

A temperature recorded in Antarctica was −123°F. The temperature recorded in the Sahara Desert was 135°F. How many degrees warmer is 135°F than −123°F
Answer:
The Sahara Desert is 258 °F warmer that Antarctica.
Step-by-step explanation:
Temperature at Antarctica = -123 °F
Temperature at the Sahara desert = 135 °F
The difference in temperature = 135 - (-123) = 135 + 123 = 258 °F
This means that the Sahara Desert is 258 °F warmer that Antarctica.
Answer:
258

Evaluate k ^5 · m If k=2 and m=5
Answer:
160
Step-by-step explanation:
We are given the equation:
k^5 * m
and asked to evaluate for k=2 and m=5. Therefore, we must substitute 2 for k and 5 for m.
(2)^5 * 5
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition and Subtraction.
Evaluate the exponent first.
—> (2)^5 = 2*2*2*2*2= 32
32 *5
Multiply 32 and 5.
160
The expression: k^5 * m when evaluate for k=2 and m=5 is equal to 160.

The answer to this expression will equal the amount you read.
The number of pages left to read will be = 5 - P.
We have a five page article.
We have to determine number of pages of this article left to read if you read P pages in the form of expression.
Express the amount of questions left to solve if you have a total of 'x' questions to solve and you have solved 'y' number of question (y < x) in the form of expression.Assume the number of questions left be n. Then -
n = x - y
According to the question, we have -
The number of pages in the article = 5
The number of pages completed = P

what are the three integers all less than 25 whose range is 10 and mean is 13
Let x be the first integer , y be the second integer , and z be the third integer
x < y < z < 25
We know that
Median=13
Median=(x+y+z)/3
13=(x+y+z)/3
x+y+z=39------> equation 1
Range=10
The range is the difference between the largest number within the set and the smallest number in the set
So range=z-x
z-x=10------> z=x+10-----> equation 2
to find the solution we will assume different values of x (See the attached table)

x < y < z < 25
z=x+10
y=39-z-x

a) through (7, 1) and perpendicular to y=-x+ 3
Step-by-step explanation:
Two lines that are perpendicular to each other has -1 as the product of thir gradient.
Since the gradient of the line y = 3 - x is -1, the gradient of the other line must be 1.
So y = x + c.
When x = 7, y = 1. 1 = 7 + c, c = -6.
Hence the equation of the line is y = x - 6.

Answer:
[tex]4 \frac{14}{99}[/tex]
Step-by-step explanation:
First off - chill with the caps dude.
Let's convert this to a mixed number.
We know that any one digit number divided by 9 will get us a repeating decimal of the number we divided by 9. For example, [tex]5 \div 9[/tex] will be [tex]0.\overline{55}[/tex].
The same goes for two digit numbers when they are over 99. [tex]32\div 99 = 0.\overline{32}[/tex]
So this means that to make [tex]0.\overline{14}[/tex] a fraction, we put 14 over 99.
[tex]\frac{14}{99}[/tex]
4 as a fraction is just [tex]\frac{4}{1}[/tex] but since they want it in a mixed number, we can just put a 4 in the beginning of the fraction.
So we get [tex]4 \frac{14}{99}[/tex].

When you switch your 8.5”x11” page from a portrait with 1” margins to landscape with 2” margins you lose how many square inches of writing space
Answer:
16.5 Squared Inches
Step-by-step explanation:
A 8.5''x11'' paper would be 7.5 in by 10 in with 1 inch margins. 7.5 x 10=75 in^2.
A landscape paper is 11''x8.5'' which would be 9 in by 6.5 in with 2 inch margins. 9 x 6.5=58.5 in^2.
75 inches squared-58.5 inches squared is 16.5 inches squared.
Therefore, you would lose 16.5 squared inches of writing space.

In this expression Marianna claims that 2X And negative X are not like terms because -x doesn't have a coefficient.Is she correct?Explain your reasoning
Answer:
She is incorrect
Step-by-step explanation:
Given:
2x and -x
Required
Like term or not?
Like terms are determined by the term itself and not by their coefficients;
Take for instance;
[tex]x^2[/tex] and [tex]2x[/tex] are not like terms because a term has square while the other doesn't
Another instance;
[tex]-3x[/tex] and [tex]2x[/tex] are like terms because they both have the presence of just 1 x
In Marianna's case;
2x and -x are like terms;
Reason being that: -x can be rewritten as -1x; giving it a coefficient of -1

Which binomials are factors of x^2 + 4x – 12?
Select the two correct answers.

Answer:
x + 6 and x - 2
Step-by-step explanation:
Given
x² + 4x - 12
Consider the factors of the constant term (- 12) which sum to give the coefficient of the x- term (+ 4)
The factors are + 6 and - 2, since
6 × - 2 = - 12 and 6 - 2 = + 4 , thus
