How can this question be solved? Please help me.

Answer: The train travels 50 miles per hour

Step-by-step explanation:

You already figured out the slope! The explanation is that the train travels 50 miles each hour.

The Slope Intercept form of the equation would be y=50x

If you substitute x with any number you can solve to see how much hours the train traveled.

So the train travels 50 miles per hour!

I hope this is what you needed help with!

Answer:

12) v=0

13) w=9

14) y=5

15) z=-8

16) n=2, m=-2

17) x=3

18) 1, because [tex]2^{4}/{2^{4} =1[/tex]. Therefore [tex]2^{4}/{2^{4} = 2^{4-4}=2^{0}=1[/tex]

Step-by-step explanation:

12) Exponent Zero rule. Anything raise to 0 power equals 1.

13) Exponent Negative rule: [tex]b^{-n} =\frac{1}{b^n}[/tex]

14) Exponent Quotient rule: [tex](a^n/a^m)=a^{n-m}[/tex]

In this case, [tex](3^3/3^5)=3^{3-5}=3^{-2}=1/3^2=1/9[/tex]

15) Exponent Product rule: [tex](a^n*a^m)=a^{n+m}[/tex]

In this case, [tex](5^8*5^{-8})=5^{8-8}=5^0=1[/tex]

16) Same rule as #15, [tex](7^2*7^{-2})=7^{2-2}=7^0=1[/tex]

17)We can work backwards here, we know [tex]2^{2} = 4[/tex] and [tex]3^{1} =3[/tex], so we need [tex]2^2/3^1=4/3[/tex].

To achieve this, use Exponent Quotient rule, what x-4=1? x=5.

Similar base: [tex](3^5/3^4)=3^{5-4}=3^{1}=1/3[/tex]. Put [tex]2^{2}[/tex] back for [tex]\frac{4}{3}[/tex]

18) 1*1*1*1=1. Anything raise to 0 power equals 1 (Exponent Zero rule). To prove this, any number(except 0) divided by itself equals 1.

Ex: 1/1=1, 4/4=1, [tex]2^4/2^4=1[/tex].

We can prove this with the Exponent Quotient rule. [tex]1=\frac{3}{3} =\frac{3^1}{3^1}=3^{1-1}=3^0=1[/tex]. No matter how I write it, it's equal to 1.

The one exception is [tex]0^{0}[/tex], which is undefined, since dividing by zero is illegal.

Hope this helps. ;)

Answer:

It is likely that you roll a 2 and a 5. There are 36 possible combinations when rolling two dice, and one of those combinations is a 2 and a 5. Therefore, the probability of rolling a 2 and a 5 is 1 in 36, which is considered likely.

Answer:

a=-2

b=3

Step-by-step explanation:

Solve the system of equations.

2a -5b = -19

3a + 5b = 9

Add the two equations together.

2a -5b = -19

3a + 5b = 9

------------------------

5a  =            -10

Divide by 5

5a/5 = -10/5

a = -2

Now we can find b

2a-5b = -19

2(-2) -5b = -19

-4 -5b = -19

Add 4 to each side

-5b = -15

Divide by -5

b = 3

a=-2

b=3

Given

2a-5b=  -19     (equation1)

3a+5b =  9       (equation2)

now add both equation 1 and equation 2

                           2a-5b=-19

                           3a+5b= 9

                           ------------------

                             5a = -10          (as +5b and -5b get canceled)

5a = -10

a = -2

(substitute in equation 2 or in equation 1)

3(-2)+ 5b= 9

-6 +5b =9

5b = 9+6

5b = 15

b= 3

therefore

a= -2

b= 3

verification:

2(-2)-5(3) = -19

-19 = -19

hence verified.

Answer:

$39.81

Step-by-step explanation:

$5.00 per pack

15 packs

25% discount for 10 or more packs

7% sales tax

paid $100

change?

A 25% discount means that you pay 75% of the price.

75% = 0.75

A 7% sales tax means that you pay 107% of the price.

107% = 1.07

15 × $5 × 0.75 × 1.07 = $60.19

$100 - 60.19 = $39.81

Answer: $39.81

Answer: its c i just took the flvs test

Step-by-step explanation:

The experimental probability that the card selected was a J, Q, or K is 1/3.

It is a branch of mathematics that deals with the occurrence of a random event.

Given that  a gamer drew one card and recorded its value.

They continued this for a total of 100 draws.

Card         A   2  3  4 5 6 7 8 9 10 J Q K

Frequency 4  7  5  6 7 6 8 10 7 10 8 12 10

The total number of cards drawn is 4+7+5+6+7+6+8+10+7+10+8+12+10 = 90.

The number of cards drawn that are either a J, Q, or K is 10+8+12 = 30.

Therefore, the experimental probability of drawing a J, Q, or K is:

30/90 = 1/3

Hence,  the experimental probability that the card selected was a J, Q, or K is 1/3.

Step-by-step explanation:

ok so you want to make a equation for this problem

im going to take you in step by. ill show you the problem in short glimpse.

Answer:

Step-by-step explanation:

Answer:

y-intercept : 8

slope: -1/2

equation:   [tex]y = -\dfrac{1}{2}x + 8[/tex]

Step-by-step explanation:

The y-intercept is where the line crosses the y axis and you can see it crosses at y = 8 (when x =0)

Slope of the line can be found by the formula (y2-y1) / (x2-x1)  where 9x1, y1) and (x2, y2) are two points on the line

Let's take the points (0, 8) and (10, 3) the two extreme points on the line

Slope = (3 - 8) / (10 - 0) = -5 / 10 = - 1/2

Equation of a line in slope intercept form is

y = mx + c

where m is the slope  

b is the y intercept

The equation of the line is therefore

[tex]y = -\dfrac{1}{2}x + 8[/tex]

Answer:

Y-intercept = 8

Slope = -1/2t

Equation = y =-1/2x+8

Step-by-step explanation:

When x = 0, y = y-intercept.

Therefore, the y-intercept is 8.

We can find the slope using the formula y2-y1 / x2-x1 = m.

Let's use the points (0,8) and (4,6)

6-8 / 4-0 = m;

m = - 1/2.

Given that the generic formula is y=mx+b, and m-slop and b=y-intercept, we have:

y = -1/2x+8.

Answer:

the answer should be B

Step-by-step explanation:

using advanced methods of taking tests and doing multiple choice I've come to realization the answer is never A and if the answer is a then you are wrong. the teachers always think that you're going to guess C so the answer will never actually be C. the last answer is D and the teacher will never make the answer D because who actually uses D. therefore using this advanced process of elimination we have cut the terms that answer should be and most definitely will be totally 100% be B. Trust

The answer is : d (2,6,18,54,162)

the geometric sequence formula : a+ ar^1 +ar^2+ar^3+...........

where r= common ratio

the sequence is : 2,6,18,54,162

  r = An/An-1         ( as per the formula)

  r = 162/54 = 3

  r = 54/18 = 3

lly common ratio =3

in the given options the only option d satisfies all  the conditions  of the geometric sequence

verification :

a= 2

ar^1 = 2*3 = 6

ar^2 = 2*9 =18

ar^3 = 2*27 = 54

ar^4 = 2*81 = 162

Answer: The number of students expected to oppose cannot be determined from the given information. More details about the context of the survey, such as the survey questions, sample size, and response rate, may be needed to make any predictions about student attitudes.

If a survey is designed in a way that encourages students to have a neutral or negative response, or if the survey is biased in some way, it could explain why students are more likely to be undecided or opposed than in favor.

It is important to analyze survey data carefully and consider factors that may influence student responses, such as demographic characteristics, prior knowledge or experiences, and social or cultural factors.

Furthermore, it may be helpful to conduct follow-up research, such as interviews or focus groups, to gain a deeper understanding of student perspectives and attitudes.

Ultimately, any conclusions drawn from survey data should be based on sound statistical methods and rigorous analysis to ensure accuracy and reliability.
