Help! My friends needs help rlly bad

Answer: m=4/7x

Step-by-step explanation:

First, you need to use the equation y2-y1/x2-x1

Plug that in and you get 2-6/-3-4

2-6= -4

-3-4=-7

Cancel out the negatives

And the answer is 4/7

====================================================

Explanation:

Let A be the tens digit and B be the units digit

We can write the number as AB. So if A = 9 and B = 2 for instance, then the number is AB = 92. Keep in mind I'm not multiplying A and B here.

"The unit digit is a prime" means B could be any of these values {2,3,5,7}. We only list the single digit primes. The value 1 is not prime.

Now multiply each of those items by 4

4*2 = 8

4*3 = 12

4*5 = 20

4*7 = 28

Of those results, only 4*2 = 8 leads to a single digit answer.

This must mean that A = 8 and B = 2

Therefore the number is AB = 82.

Answer:y+3

Step-by-step explanation:took a test

Answer:

Draw the line segment AB = 7 cm.

Draw ray BX making an acute ∠ABX.

Along BX. mark off five points B1, B2, B3, B4 and B5. Join B2 to A.

Through B5 draw B5P || B2A, intersecting BA produced at P.

The point P so obtained is the required point which divides AB externally in the ratio 3:5.

Answer:

[tex]y = 12 + 6x[/tex]

Step-by-step explanation:

Given

[tex]Base\ Amount = 12[/tex]

[tex]Additional = 6[/tex] per hour

Required

Determine the expression for the cost in x hours

Represent the cost with y

y is calculated using the following expression

[tex]y = Base\ Amount + Additional * x[/tex]

Where x represent the number of hours.

Substitute values for the base amount of bike and the additional cost per hour

[tex]y = 12 + 6 * x[/tex]

[tex]y = 12 + 6x[/tex]

So, the expression to determine the cost of bike in x hours is: [tex]y = 12 + 6x[/tex]

Answer:

$417.52

Step-by-step explanation:

Present value of annuity = P * {1-[1/(1+r)^n]/r}

P =Periodic payment i.e. 75

r = rate of interest per period i.e. 16.2% /4 = 4.05% or 0.0405

n =no. of compounding period i.e. 1.50*4 =6

Present value of annuity = Loan amount

Present value of annuity = 75 * {1-[1/(1+0.0405)^6]/0.0405}

Present value of annuity = 75 * {1-[1/(1.0405)^6]/0.0405}

Present value of annuity = 75 * {1-[1/1.268973)/0.0405}

Present value of annuity = 75 * (1-0.78804)/0.0405

Present value of annuity = 75 * (0.21196/0.0405)

Present value of annuity = 75 * 5.23361

Present value of annuity = 392.52

Loan amount = $392.52

Selling price = $392.52 + $25.00

Selling price = $417.52

Thus, the selling price of the skis is $417.52

Answer:

17-2x =-11 I got 14

Step-by-step explanation:

Subtract the 17 from the -11 which will be -28 and then divided -28 by -2 and your answer is 14

Answer:

alternate exterior angles

Step-by-step explanation:

Answer: adjacent angles

explanation: both angles share the same side.

Answer:

130 degrees

Step-by-step explanation:

So u can see those little lines on two of the sides of the triangle, it means that it's congruent also meaning the same length, and if u didn't, the angles had to be the same in order for the sides to be the same length. So the other missing angle degree is also 25 degrees. A triangle is 180 degrees, so with this info:

25 + 25 + 4x + 2 = 180

4x + 52 = 180

4x = 128

x = 32, now we have x so replace the x in the equation with 32

4(32) + 2

128 + 2

130

Answer: The answer is C Have a good day

Step-by-step explanation:

Answer:

The answer would be $18,144.

Step-by-step explanation:

First you have to figure out how many hours are in one week. 168 hours are in one week. The problem is asking us for 12 weeks. You would have to multiply 168 by 12 to see how many hours it would be. 168 times 12 is 2,016. Ricki earns $9 every hour. Next, you would have to multiply the 2,016 by 9 to give you 18,144. I hope this helps.

Answer:

Rachel's error is in the inequality sign

Step-by-step explanation:

Given

[tex]x \geq 2[/tex]

Required

Determine the error in Rachel's workings

From the question, we understand that both sides of the inequality were multiplied by 3

i.e.

[tex]3 * x \geq 2 * 3[/tex]

This gives

[tex]3 x \geq 6[/tex]

Comparing this to Rachel's result: [tex]3 x \leq 6[/tex]

We can conclude that Rachel's error is in the inequality sign.

The sign of an inequality will only change is it is being multiplied or divided by a negative number; otherwise, the sign remains unchanged

Answer:

w=40

Step-by-step explanation:

w=40 because when you subtract 40-8 the sum is 32 so W=40

w-8=32

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

add 8 to -8, and 32.

8 and -8 will cancel out. 32 and 8 will increase though. So, it should be:

w=40

Answer:

La respuesta es D. 24

Step-by-step explanation:

Falta el esquema. Lo adjunto en la resolución de la pregunta.

En el esquema se puede ver que hay 3 maneras de ir desde la ciudad A a la ciudad B, 4 maneras de ir desde la ciudad B hacia la ciudad C y finalmente 2 maneras de ir desde la ciudad C hacia la ciudad D.

Necesitamos saber por cuántas rutas se podría ir si se desea viajar desde la ciudad A a la ciudad D.

Utilizaremos el principio de multiplicación para responder a ésta pregunta ⇒

Supongamos que estamos realizando un experimento [tex]N[/tex] el cuál está conformado por una serie de sub - experimentos [tex]m_{1},m_{2},...,m_{n}[/tex].

Ahora, cada uno de estos sub - experimentos se puede desarrollar de [tex]n_{1},n_{2},...,n_{n}[/tex] maneras diferentes respectivamente. Entonces, el número total de maneras diferentes en las que el experimento [tex]N[/tex] se puede llevar a cabo se calcula como [tex]n_{1}[/tex] x [tex]n_{2}[/tex] x . . . x [tex]n_{n}[/tex]

Ahora bien, siguiendo con ésta idea escribimos :

3 x 4 x 2 = 24

''3'' porque es el número de rutas distintas para ir de A hacia B

''4'' porque es el número de rutas distintas para ir de B hacia C

Y finalmente ''2'' porque es el número de rutas para ir desde C hacia D

Si hacemos éste producto el resultado es 24 y por lo tanto la opción correcta es D. 24
