Hello!! Please help me solve the question, could you please also tell me which calculator we can use? Thank you

Answer:

It's rational because it's not a decimal numbet

Answer:

No solution

Step-by-step explanation:

1 = 1/3(2) + 5

1 = 17/3

1 is not equal to 17/3

so the answer has no solution meaning the point does not exist in the graph.

pls ❤ and mark brainliest pls!

what nice question that we can understand ok

Answer:

Step-by-step explanation:

I'm assuming that the length of the spring is s and the mass of the object is m. If that be the case, the direct variation equation, which a line btw, is

s = km where k is the constant of proportionality. We have to solve for k, the slope of the line, in order to determine the model for this situation.

9 = k(30) so

[tex]k=\frac{9}{30}=\frac{3}{10}[/tex] Now that we know, the slope of the line, we can rewrite the equation with the slope in place:

[tex]s=\frac{3}{10}m[/tex], choice A.

Answer:

There are 10 mm in one cm, so 100 mm is equal to 10 cm.

Step-by-step explanation:

5^2+12^2=25+144=169=13^2 which will form a right angle triangle

Answer:

2/3

Step-by-step explanation:

the points are (2,-5) and (5,-3)

the slope is change in y over change in x

so the slope can be written as:

(-3-(-5))/(5-2)

thats 2/3

and thats the slope

Answer:

could i have the website info  or the image clearer so i could try and help you

Step-by-step explanation:

If n = 0.151515…, then 100n = 15.151515…

Then

100n - n = 15.151515… - 0.151515…

99n = 15

n = 15/99 = 5/33

Answer:

The latest time Ruth's family can start their tour in order to make it to dinner on time is 2:50 P.M

Step-by-step

Change:

7h10= 430 mins

1 hour and 25 minutes= 85 mins

2 hours and 5 mintues= 125 mins

- Total time Ruth wants to do before his dinner reservations:

85+ 125+ 50= 260 (mins)

- The latest time Ruth's family can start their tour in order to make it to dinner on time:

430- 260= 170 (mins)

Change: 170 mins= 2 hours and 50 minutes

Good luck!

Answer:

x^3y^3

Step-by-step explanation:

She made the mistake of multiplying 'x' 5 times

=> xy3.x2 = xy.y.y.x.x = x.x.x.y.y.y = x^3y^3

Answer:

First, find the value of x:

[tex]h(5-x)=h(9)\\5-x=9\\-x=9-5\\-x=4\\x=-4[/tex]

Substitute the x-value in to the function [tex]x^{2}+x+1[/tex] and solve:

[tex](-4)^{2}+(-4)+1=16-4+1=12+1=13[/tex]

Therefore, the value of h(9) = 13.

Hope this is correct O-o

Answer:

A

Step-by-step explanation:

Since we need to find the value of h(9), we can substitute the (5-x) part from the original equation with 9 to get the value of x, which is 5-x = 9, x = -4. With that, we can go ahead and plug the x into the right side of the equation to get (-4)^2 + (-4) + 1, which equals 16 - 4 + 1, which equals 13.

I hope this helped! Please do let me know if you have further questions :D

Answer:

y = 10 between 0 and 1

AND

y=15x for x>=1

Step-by-step explanation:

This has 2 segments. One when 0 < x < 1 (y=$10), and one when x >= 1 (y=$15x)

So

y = 10 between 0 and 1

AND

y=15x for x>=1
