Select each correct answer.
When (-1,-4) is substituted into the second equation, the equation
is true.
The ordered pair (-1,-4) is a solution to the system of linear
equations.
When (-1,-4) is substituted into the first equation, the equation is
true.
When (-1,-4) is substituted into the second equation, the equation
is false.
When (-1,-4) is substituted into the first equation, the equation is
false.
The ordered pair (-1,-4) is not a solution to the system of linear
equations.
Answer:
When (-1,-4) is substituted into the second equation, the equation is true.
The ordered pair (-1,-4) is a solution to the system of linear equations.
When (-1,-4) is substituted into the first equation, the equation is true.
Step-by-step explanation:
Given
[tex]x - y = 3[/tex]
[tex]7x - y = -3[/tex]
Required
What is true about [tex](x,y) = (-1,-4)[/tex]
To do this, we substitute -1 for x and -4 for y in both equations;
For [tex]x - y = 3[/tex]
[tex]-1 - (-4) = 3[/tex]
[tex]-1 + 4 = 3[/tex]
[tex]3 = 3[/tex]
Hence: [tex](-1,-4)[/tex] is true for [tex]x - y = 3[/tex]
For [tex]7x - y = -3[/tex]
[tex]7(-1) - (-4) = -3[/tex]
[tex]-7 +4 = -3[/tex]
[tex]-3 = -3[/tex]
Hence: [tex](-1,-4)[/tex] is true for [tex]7x - y = -3[/tex]
write an equation perpendicular to 4x + 8y = 3 and contain the point (5,7) in slope-intercept form
Answer:
y=2x-3
Step-by-step explanation:
The slope-intercept form of the original equation would be y=3/8−x/2
Therefore, the slope of the perpendicular line would be m=2
Then, the y-intercept would be 7=(2)x(5)+a
A=-3
Answer:
y=2x+3

Answer:
BANANA CREME PIEEEE
Step-by-step explanation:
the answer is 7
Answer:
Most people when asked, “What is the equation of a line?”, will answer, “y = mx + b”. This is the
equation of a line in what is called slope-intercept form where “m” is the slope and “b” is the yintercept. So, how do you find the equation of a line? There are several different ways that you can find
the equation of a line. I find the equation of a line everytime by following the same three steps:
Step 1: Find the slope of the line.
Step 2: Use the slope to find the y-intercept.
Step 3: Use steps 1 and 2 to write the answer.
I will explain these steps by looking a several examples. Please understand that there are often several
different ways to complete each math problem, but I have found through the years that students are most
successful when the do problems the same way each and every time they attempt the problem. If you
know a different way to find the answer that is great, but I am going to show how to do the problem one
way and use the same technique everytime I see this problem.

Three friends share the total cost of a game. Joe pays 30%, mike pays 2/5 and tony pays the rest. Who paid the most ?
Answer:
Mike pays the most.
Step-by-step explanation:
Joe pays 30%, given, and Mike pays 2/5, also given. You can covert 2/5. into a percentage by multiply both the numerator and denominator by 20 which gives you 40/100 = 40%. If Mike and Joe combined pay 40%+30% = 70%, then Tony only pays 30%. Therefore Mike would pay the most.

For the equation 2x + 7 =30, x = 3
O True
O False
Answer: False
=============================================================
Explanation:
To see if the x value is a solution or not, we plug it into the equation given
2x+7 = 30 .... original equation
2*3 + 7 = 30 .... replace every x with 3, since we claim that x = 3
6 + 7 = 30 .... multiply 2 and 3 to get 6
13 = 30 ...... add 6 and 7 to get 13
We get two different numbers on either side, so the last equation is not true. We get a contradiction or false statement. So the original equation is false when x = 3. Therefore, x = 3 is not the solution.
That's why the overall claim is false.
Type the correct answer in the box. Use numerals instead of words.
What value of x makes this equation true?

5) In August, Yesenia was 4 feet tall. Each month since August, she has consistently grown 0.25 inc
How tall is Yesenia t months after August?
Answer:
Yesenia is 0.25t+4 inches tall after August.
Step-by-step explanation:
Given that:
Height of Yesenia in August = 4 feet tall
Growth rate since August = 0.25 inches
Number of months after August = t
According to given statement;
Height after August = Growth rate * Number of months + Height in August
Height after August = 0.25t + 4
Hence,
Yesenia is 0.25t+4 inches tall after August.
