Answer:
b
Step-bystep explanation:
when subtracting you could reverse it and add so add back the 2.50 to the 5 and if he spent half of what he had left the that would mean he had another 5 dollars. in total he had 12.50$
The answer is b the square root of 65
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>
If g(x) = 7x, then plug 7x in for g(x) in the inequality.
<span>g(x) > 28
</span><span>7x > 28
To solve this inequality, divide both sides by 7.
7x / 7 = x
28 / 7 = 4
x > 4 when g(x) = 7x and g(x) > 28.
So the answer is x > 4.
Hope this helps!</span>
