If 3^2x+1= 3x+5, what is the value of x?<br> 2<br> 3<br> 4<br> 6
REY [17]

Answer:

x = 4

Step-by-step explanation:

Set the exponents equal to each other

3^{2x+1}=3^{x+5}

2x + 1 = x + 5

Subtract x from both sides

x + 1 = 5

Subtract one from both sides

x = 4

So, the value of x is equal to 4.

What is the slope of the line that passes through the points (−8,−1) and (−6,−2)? Write your answer in simplest form.
4vir4ik [10]

Answer:

m = -1/2

Step-by-step explanation:

Recall that slope = (change in y) / (change in x).

Going from  (−8,−1) to (−6,−2), x increases by 2 (because -6 - (-8) = 2), and

y decreases by 1.  Thus, the slope here is

m = (change in y) / (change in x) = (-1) / 2 = -1 / 2

m = -1/2
