Answer 1

Answer:

n=−2.5

improper fraction: 5/2

Step-by-step explanation:

Step 1: Flip the equation.

2n=0.176777

Step 2: Solve Exponent.

2n=0.176777

log(2n)=log(0.176777)(Take log of both sides)

n*(log(2))=log(0.176777)

n=

log(0.176777)

log(2)

n=−2.5

then just make it an improper fraction = 5/2

or a mixed number = 2 1/2

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.

write an equation perpendicular to 4x + 8y = 3 and contain the point (5,7) in slope-intercept form

Answers

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

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?

Answers

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.

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 ?

Answers

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.

The answer is false
Have a good day <3

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.

Answers

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]
