The formula for x in terms of w is x = 3w² and the formula for y in terms of x is y = (1/112)x³

<h3>Variation</h3>

x = k × w²

w = 4, x = 48

48 = k × 4²

48 = k × 16

48 = 16k

k = 48/16

k = 3

So,

x = k × w²

x = 3 × w²

x = 3w²

y = k/x³

x = 2, y = 14

14 = k / 2³

14 × 2³ = k

14 × 8 = k

112 = k

So,

y = k/x³

y = 112/x³

y = (1/112)x³

Answer:

Step-by-step explanation:

First, use the distributive property: 2x+16=4x+8

Second, move +8 to the other side(and turn it negative): 2x+8= 4x

Do the same for +2x: 8=2x

divide both sides by 2: 4=x

A line has a slope of

padilas [110]

Step 1. The General Equation of a straight line is

Y = Mx + C where

M is the slope and
C is that point on the y axis where the curve cuts that axis (where x = 0)
In this case we are told that M = (3/4)

Our equation is now Y = (3/4)X + C ••• Equ 1

We are told that this curve passes through Point ( x, y ) = ( 8, -1 ).

Substitute these values of x, and y into Equ 1 to find C.

Y = (3/4)X + C or

( -1 ) = ( 3/4 )*( 8 ) + C or

( -1 ) = ( 6 ) + C or

C = ( - 7 )

Therefore the Equation of the Point Slope curve is

Y = ( 3/4 )X - 7

What does x equal? Please help. No trolls

Answer:

The value of 'x' is 17.

Step-by-step explanation:

Given:

Δ IJK ≅ ΔPQR

m∠I = 3x + 4

m∠P = 72 - x

To Find:

x = ?

Solution:

Δ IJK ≅ ΔPQR ...........Given

If two triangles are congruent then the corresponding angles of congruent triangles are congruent.

∴∠ I ≅ ∠ P ........corresponding parts of congruent triangle (CPCT)

Substituting the values we get

$3x+4=72-x\\\\3x+x=72-4\\\\4x=68\\\\\therefore x=\dfrac{68}{4}=17\\\\\therefore x =17$

The value of 'x' is 17.

Answer:

a) X = 2/15 , 8/15, 1/3

b) attached below ( probability plot )

C) F(x ) attached below

d) cumulative probability plot

Step-by-step explanation:

a) Determine the probability of Function X

P( x = 0 ) = 6 / 45 = 2 /15 = 0.1333

P( x = 1 ) = 8/15 = 0.5333

P( x = 2 ) = 1/3 = 0.3333

Hence the probability of Function X = 2/15 , 8/15, 1/3

b) Graph of the probability Function of X

x 0 1 2

p(x) 0.1333 0.5333 0.3333
