Write the direct variation function given that y varies directly with x, and y = 1.5 when x = 5.
Cloud [144]

Answer:

y=0.3x

Step-by-step explanation:

Formula = K=\frac{y}{x}

y α x

y = kx

Where k is the constant of proportionality.

When y = 1.5; x = 5;

We substitute these known values in the equation,

y = kx

1.5 = k5

Dividing both sides of the equation by 5 to find the value for k, we have

1.5/5= k0.3/5

Therefore,

K = 0.3

Having found the value of k,

We substitute this value into the relationship

y = kx

Therefore we have,

y = 0.3x.

The direct variation function is therefore,

y = 0.3x.

Please help soon! Thanks! Solve for x
EastWind [94]

Answer:

x=30^{\circ}

Step-by-step explanation:

Looking at \triangle LMN:

\angle NML = 180 - (90+45) (angle sum of triangle is 180^{\circ})

=45^{\circ}

Looking at \triangle KNM:

\angle KNM = 180-105 (angle of straight is 180^{\circ})

=75^{\circ}

\angle KNM + \angle NKM + \angle KMN = 180 (angle sum of triangle is 180^{\circ)

75+2x+45 = 180

2x+120 = 180

2x=60

x=30^{\circ}

Hope this helps :)
