Answer:
There are two ways to solve this question. The faster way is to multiply each side of the given equation by ax−2 (so you can get rid of the fraction). When you multiply each side by ax−2, you should have:
24x2+25x−47=(−8x−3)(ax−2)−53
You should then multiply (−8x−3) and (ax−2) using FOIL
("First, Outer, Inner, Last")
24x2+25x−47=−8ax2−3ax+16x+6−53
Then, reduce on the right side of the equation
24x2+25x−47=−8ax2−3ax+16x−47
Since the coefficients of the x2-term have to be equal on both sides of the equation, −8a=24, or a=−3.
The other option which is longer and more tedious is to attempt to plug in all of the answer choices for a and see which answer choice makes both sides of the equation equal. Again, this is the longer option, and I do not recommend it for the actual SAT as it will waste too much time.
soo the final answer is B -3
Answer:-2/3
Explanation:Give 3 to parenthesis.
3x+3y=y
Add like terms
3x=y-3y>>>3x=-2y
Get x alone By dividing 3 from both sides
X=-2/3y
Answer:
4/9
Explanation:
√8^a=4^b/3.
You can rewrite √8^a as 8^a/2.
So then that would be, 8^a/2=4^b/3.
If both sides have the same base, we could then make the fractional exponents equal to each other. Since 2^3=8 and 2^2=4, we can make that possible.
2^3(a/2)=2^2(b/3).
2^3a/2=2^2b/3.
So now 3a/2=2b/3.
Then we isolate the a, by multiplying 2/3 on both sides and are left with:
a=2/3*2/3*b
a=4/9*b
Then you divide both sides by b to get:
a/b=4/9.
