Given that y is directly proportional to x. If y = 30 and x= 5, write an equation that connects y with x.
alukav5142 [94]

Answer: y = 6x

Step-by-step explanation:

Since this is a direct proportion, we will introduce the constant of proportionality here and this will be:

y = kx

Since y = 30 and x= 5,

30 = 5 × k

30 = 5k

k = 30/5

k = 6

Therefore, the equation that connects y to x will be:

y = kx

y = 6x

The equation that connects y to x is y = 6x.

A rectangle has a length of 3x + 7 and a width of 2x. If the perimeter of the
Art [367]

Answer:

The length of the rectangle is 31.

Step-by-step explanation:

We have that the length (L) and width (W) are:

L = 3x + 7

W = 2x

The perimeter of the rectangle is given by:

P = 2W + 2L

94 = 2(2x + 3x + 7)

94 = 10x + 14

x = 8

Now, we can calculate the length of the rectangle:

L = 3x + 7 = 3*8 + 7 = 31        

         

Therefore, the length of the rectangle is 31 units.

I hope it helps you!

Pls answer this question for the 5-star rating
zheka24 [161]

Answer:

B(3,3)

Step-by-step explanation:

Midpoint = (2,5)

A = (x₁,y₁) = (1,7)

M(x,y) = (\frac{x1+x2}{2} , \frac{y1+y2}{2})

M(2,5) = (\frac{1+x2}{2} , \frac{7+y2}{2} )

<em>Writing the equations separately for convenience</em>

1) \frac{1+x2}{2} = 2  

=> 1+x2 = 4

=> x₂ = 3

2) \frac{7+y2}{2} =5

=> 7+y2 = 10

=> y₂ = 3

So, the coordinate is,

B = (x₂,y₂) = (3,3)
