solve the system of equations y=9x+13 y=2x+48 what does the second one equal

Given:

y is proportional to x.

y=20 and x=12.

To find:

The constant of proportionality and the equation for the proportional relationship.

Solution:

y is proportional to x.

[tex]y\propto x[/tex]

[tex]y=kx[/tex]              ...(i)

Where, k is the constant of proportionality.

Putting y=20 and x=12, we get

[tex]20=k(12)[/tex]

[tex]\dfrac{20}{12}=k[/tex]

[tex]\dfrac{5}{3}=k[/tex]

Putting [tex]k=\dfrac{5}{3}[/tex] in (i), we get

[tex]y=\dfrac{5}{3}x[/tex]

Therefore, the contestant of proportionality is [tex]k=\dfrac{5}{3}[/tex] and the equation for the proportional relationship is  [tex]y=\dfrac{5}{3}x[/tex].

Answer:

y=2.5x-3

Step-by-step explanation:

first, we find the y-intercept, which is the number with a zero in the x

That would be -3

next, we find the slope

to do this, we have to take two numbers on the y side next to each other and subtract.

For this example we will use 7 and 2

7-2=5

And just to be positive, we will also do 12 and 7

12-7=5

Okay, now that we know that the number is growing by 5 every time, we know that it is now 5/2 because y is growing by 5 and x is growing by 2

Now, we make the x side grow by only 1, so to do this, we will divide both sides by two.

Now we have 5/1 or just 5

Finally, to put that into the right format, we do y=5x-3

You're Welcome

Good Luck

Answer:

Step-by-step explanation:

A + B = 7

(Not A) + B = 5

(Not A) + (Not B) = 8

(Not A) = ((Not A) + B) + ((Not A) + (Not B) = 13

A = 20 - (Not A) = 7

Prob (A + B) given (A)

Prob (A+B) || A = (7/20) / (7/20)

Prob (A + B) || A = 1

Answer:

it is d because the age of 200

The required measure of Street K between Street C and D is 337.5 ft.

Given that,
In a certain city, E Street, W Street, C Street, and D Street are parallel streets that intersect K Street and M Street. How long is K Street between C Street and D Street is to be determined.

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.

here,
Let the distance of street K between C and D be x,
Now,
Taking the equality of the proportionality expression of triangles,
600 / 400 = 600 + x / 400 + 250
6 / 4 = 600 + x / 625
3750/4 = 600 + x
937.5 = 600 + x

x = 337.5

Thus, The required measure of Street K between Street C and D is 337.5 ft.

Answer:

12 miles

Step-by-step explanation:

25 - $1 fee= 24/$2 per mile = 12 miles

Answer:

12mi

Step-by-step explanation:

First find the equation implied by this problem. Using m as the unknown number of miles, we find:

$1 + $2m = $25

2m = 24

m = 12mi

I fu-ck-ed my girl-friend real good

Step-by-step explanation:

1)

SA= 2 (Length x Breadth + breadth x height + Length x height)

SA= 2(2*5+5*6+6*2)=2(10+30+12)=104cm^2

2)

2(3*4+4*5+5*3)= 2(12+20+15)=94cm^2

3)

2(7*9+9*12+12*7)=2(63+108+84)= 510cm^2

4)

SA=

[tex]A=2πrh+2π {r}^{2}

[tex]A=2πrh+2π {r}^{2} [/tex]

= 2π 6*5+2π6*6= 188.495+226.194

SA= 414.689 cm^2

5)

2π7*4+2π*4*4=

SA=276.46 cm^2

6)

2π6*4+2π*4*4=

SA= 251.33 cm^2

7)

(3*4)/2=6

(3*4)/2=6

(3*8)=24

4*8=32

8*5=40

SA =6+6+24+32+40=108 cm^2

8)

(6*8)/2=24

(6*8)/2=24

6*12=72

8*12=96

10*12=120

SA= 24+24+72+96+120= 336 cm^2

9)

(5*12)/2=30

(5*12)/2=30

5*8=40

12*8=96

13*8=104

SA= 30+30+40+96+104= 300 cm^2

Answer: 162.6cm

Step-by-step explanation:

4 boys have a mean height of 162cm. Their total height will be the average multiplied by the number of boys which will be:

= 162 × 4

= 648cm

A new boy with height of 165cm joined. This means that we now have 5 boys and their total height will be:

= 648cm + 165cm

= 813cm

The new mean height will be:

= Total height / Number of boys

= 813 / 5

= 162.6cm

Answer:

y=x-3

Step-by-step explanation:

slope intercept form equation is y=mx+b

b is the y intercept(where it crosses on the y-axis)

b=-3

m is the slope

slope is rise over run (start from -3)

slope is 3 over 3 (count up 3 from -3, count right 3)

3 over 3 is 1

1x is the same as x

final answer y=x-3
