The solutions are given below:

1. 3y- 9 = 2x

2.  2/3.

3. y/x

4.  y = (2/3)x + 3

<h3>What is equation of line?</h3>

The equation of a line with one given point (x1, y1) is (y - y1) = m(x - x1). Here m is the slope of the line.

The complete question is:

On a coordinate plane, a line goes through (0, 3) and (x, y). A triangle has a rise of 2 and run of 3. A larger triangle has a rise of 5 and run of 7.

Use similar triangles to determine the equation of the line with a slope of 2/3 that passes through the point (0, 3).

What is the ratio of the rise to the run in the smaller triangle in the diagram?

What is the ratio of the rise to the run in the larger triangle in the diagram?

What is the equation of the line in slope-intercept form?

1. slope= 2/3

coordinates= (0, 3)

y-y1 = m(x-x1)

y-3 = 2/3(x-0)

y-3 = 2/3x

3y- 9 = 2x

2. The ratio of the rise to the run in the smaller triangle in the diagram

is y/x = 2/3

3. The ratio of the rise to the run in the larger triangle = y/x

4. The equation of the line in slope-intercept form is given by:

  y = (2/3)x + 3

How would I find all real solutions in x^4/3 -10^2/3 +21= 0
Oxana [17]

Answer:

Step-by-step explanation:

This equation looks complicated.We have to make it easier

let's say x^2/3 = t  and  x^4/3 = t^2

     

      t^2-10t+21=0   [ we can factorize this equation as a (t-3)(t-7) ]

     

      (t-3)(t-7)=0  [ that means , t can be 3 or 7 ]

But don't forget we have to find x not t so,

   t=x^2/3=3     ∛ x^2 = 3       x^2 = 9    x=3 or x= -3

  t=x^2/3=7      ∛x^2 = 7        x^2 = 343    x ~18.5  or x ~ -18.5

Need help asap please!!<br> This is the only one i don’t know i’m stuck!
lyudmila [28]

Answer:

Reminder that is this form  a(b)^x  where  a > 0

When   b > 0  but < 1 that is a decay function

When   b > 1 than its a growth function

Step-by-step explanation:

So following this you can figure out the answer

g(x)=0.3(x)      

this is neither since there is no exponent (linear)

H=72(56)^t    

this is growth since b  = 56

A=(43)^t        

this is growth since b  = 43 ("a" is understood as "1")

H=5.9(0.82)^t      

this is decay since b =  0.82

y=0.8(3.6)^t      

this is growth since b = 3.6

f(t)=0.72(15)^t    

this is growth since b  = 14  

A=49(8)^t      

this is growth since b  = 8
