Answer:

y = -5x - 7

Step-by-step explanation:

What's the slope of this line?  Going from  (7,-42)  to  (10,-57), we see x increasing by 3 and y decreasing by 15.  Thus, the slope is m = rise / run = -15/3, or m = -5.  

Now subst. -42 for y in y = mx + b, -5 for m and 7 for x:

-42 = -5(7) + b.  Thus, b = -42 + 35, or b = -7. and the equation of this line is thus   y = -5x - 7.

Check:  if x = 10, does this equation yield y = -57?  Yes

Solving the equation and something to do with log
Anastaziya [24]

Answer:

m= 1/2.

Step-by-step explanation:

To solve this, we must make the bases equivalent. We can do this by finding the common base which is 5.

We know that 125= 5³ and 25=5², which will help us in this equation. We can rewrite the equation substituting this for the original numbers:

5^{3(2m)} = 5^{2(m+1)} Distribute the exponents to get:

5^{6m} = 5^{2m+2}

Now, we can simply ignore the '5' and solve for 'm':

6m= 2m+2

4m= 2

m= 1/2.
