0.3f +1 = 0.2f - 4.5<br> What’s the answer step by step
jok3333 [9.3K]

Step-by-step explanation:

.3f+1 = .2f-4.5

1. Subtract .2f both sides

.1f+1 = -4.5

2. Subtract 1 from both sides

.1f = -5.5

3. Divide .1 both sides

f = -55

To check plug in -55 to all the f’s and both sides should be equal.

Hope this helps!

pentagon [3]

Answer:

c  This is the direct variation

Step-by-step explanation:

The equation for direct variation is y= kx

Solving this for k

y/x =k

So y/x must be a constant

a.  9/3 =3

2/7 does not =3  so this is not a direct variation


b 1/2 = .5

-3/6 = -.5

This is not the same so this is not a direct variation


c.  27/9 =3

18/6 =3

9/3 =3

This is a direct variation with a constant of 3


d 5/-7 = -5/7

1/-3 = -1/3

This is not the same so this is not a direct variation
