Answer:(-1.412,-2.124),(3.29,7.28)

Step-by-step explanation:

Given

The given equation is 2^x-2.5=2x+0.7

There are two functions i.e. y=2^x-2.5\ \text{and}\ y=2x+0.7

Their intersection gives the solution of the above function

From the graph, we can see that both the graph intersects at two different points i.e.  at

How to solve a equation like:<br> 2m = -2/3
adell [148]

Answer:

m = -\frac{4}{3}

Step-by-step explanation:

2m = -\frac{2}{3}

Divide both sides by 2 to get just m

\frac{2m}{2} = \frac{-\frac{2}{3}}{2}

You can't divide a fraction by a number so you do kcf (keep it, change it, flip it)

m = -\frac{2}{3} x \frac{2}{1}

m = -\frac{4}{3}

Can someone please help me out with this its really urgent Ill mark brainliest
Alex73 [517]

Answer:

smart dot company c=.50t+12

communication plus c=2.50t

Step-by-step explanation:

smart dot has the starting point of $12 per month already so that would be your y-intercept with the equation being y=mx+b , y being the cost m being the amount of money per hour, x being the time spent, and b being the starting cost.

So with that smart dot would be c=.50t+12

with communication plus not having that starting point it would just be c=2.50t
