How do I answer this question?

elena-14-01-66 [18.8K]

a and b represent the slopes in the equations. Use the y-mx+b formula to realize this. M is the slope, a or b in this question. The lines both have positive slopes so B or C cannot be the answer. I cant see the image properly, but if the y int is at 0 then A is the answer, but if it is above 0 then D will be your answer.

If 3x − y = 12, what is the value of 8^x/2^y?

ivanzaharov [21]

Answer:

Explanation:

Let's solve the equation to be written as y in terms of x by adding y to and subtracting 12 from both sides:

3x - y = 12

3x - 12 = y

Now, replace y in the other expression that we want to find ( $8^x/2^y$ ) with this expression 3x - 12:

$8^x/2^y$

$8^x/2^{3x-12}$

Now, we also know that 8 = 2³, so substitute 2³ for 8 in the expression:

$8^x/2^{3x-12}$

$(2^3)^x/2^{3x-12}=2^{3x}/2^{3x-12}$

Remember that when dividing powers with the same base (in this case, the common base is 2), the result will be a single power whose exponent is the difference of the other two powers. Here, then we have:

$2^{3x}/2^{3x-12}=2^{3x-(3x-12)}=2^{12}$
