We can combine thos fraction ssince same denomenator
\frac{3y}{7}+ \frac{1}{7}= \frac{3y+1}{7}

so
\frac{3y+1}{7}= \frac{3}{7}

times both sides by 7
3y+1=3
minus 1 both sides
3y=2
divide both sides by 3

mylen [45]

Answer:

y = 10( {4}^{x} )

Step-by-step explanation:

From the given exponential graph, the y-intercept is (0,10).

The only exponential function that, has this intercept is

y = 10( {4}^{x} )

Because when x=0, we obtain:

y = 10( {4}^{0} )

Simplify:

y = 10(1) = 10
