Answer:
x = 16.1051577
Step-by-step explanation:
tan0 = opp/adj
tan0 = 14/x
tan(49)× 14 = 16.1051577
Multiply each side of the given equation by <span>ax−2</span> (so you can get rid of the fraction). When you multiply each side by ax−2, you should have:
<span><span><span><span>24 x ^2 </span>+ 25x </span>− 47 </span>= <span><span><span>(<span><span>−8x</span>−3</span>)</span><span>(<span>ax−2</span>)</span></span>−53</span></span>
You should then multiply <span>(<span><span>−8x</span>−3</span>)</span> and <span>(<span>ax−2</span>)</span> using FOIL.
<span><span><span><span>24 x ^2 </span>+ 25x </span>− 47</span>= <span><span><span><span><span>−<span>8ax^2 </span></span>− <span>3ax </span></span>+ 16x </span>+ 6 </span>− 53</span></span>
Then, reduce on the right side of the equation
<span><span><span><span>24 x ^2 </span>+ 25x </span>− 47</span>= (<span><span>−<span>8x </span></span>− <span>3(ax - 2) - 53</span></span></span>
Since the coefficients of the x^2-term have to be equal on both sides of the equation, <span><span>−8a</span>=24</span>, or <span>a=−3</span>.
Your answer would be <span>
B</span>
Answer:
x - 7 < - 12 A: -6 or less ... -7, -8, -9 etc
-9x (90) A: -10
3 + v > -9 A: -11 or more ... -10, 1, 0, 1238 etc
Step-by-step explanation:
1. if it has to be less than -12 the number must be farther left then -12
2. negative times negative = positive
3. use any number higher than -9
Add 2 to both sides
a>4+2
simplify 4+2 to 6
a > 6 is the answer
