The range is y values and domain is x values
y intercept here is 5 and since the function is increasing thus the range would be all real values bigger than or equal to 5
And the domain would be all real numbers.
<span><span><span><span><span>(<span>−a</span>)</span><span>(b)</span></span>+<span>8a</span></span>−5</span>−<span>(<span><span><span>(<span>−<span>8a</span></span>)</span><span>(b)</span></span>−4</span>)</span></span>
So first
Distribute the Negative Sign:
<span>=<span><span><span><span><span>(<span>−a</span>)</span><span>(b)</span></span>+<span>8a</span></span>−5</span>+<span><span>−1</span><span>(<span><span><span>(<span>−<span>8a</span></span>)</span><span>(b)</span></span>−4</span>)
</span></span></span></span><span>=<span><span><span><span><span><span><span>(<span>−a</span>)</span><span>(b)</span></span>+<span>8a</span></span>+</span>−5</span>+<span><span>−1</span><span>(<span><span>(<span>−<span>8a</span></span>)</span><span>(b)</span></span>)</span></span></span>+<span><span>(<span>−1</span>)</span><span>(<span>−4</span>)
</span></span></span></span><span>=<span><span><span><span><span><span><span>(<span>−a</span>)</span><span>(b)</span></span>+<span>8a</span></span>+</span>−5</span>+<span><span>8a</span>b</span></span>+4</span></span><span>=<span><span><span><span><span><span>−<span>ab</span></span>+<span>8a</span></span>+</span>−5</span>+<span><span>8a</span>b</span></span>+4
</span></span>
Then after all of that
Combine Like Terms:<span>=<span><span><span><span><span>−<span>ab</span></span>+<span>8a</span></span>+<span>−5</span></span>+<span><span>8a</span>b</span></span>+4
</span></span><span>=<span><span><span>(<span><span>−<span>ab</span></span>+<span><span>8a</span>b</span></span>)</span>+<span>(<span>8a</span>)</span></span>+<span>(<span><span>−5</span>+4</span>)
So now your answer is </span></span></span><span>=<span><span><span><span>7a</span>b</span>+<span>8a</span></span>+<span>−<span>1</span></span></span></span>
Answer:
D
Step-by-step explanation:
The range of a graph is the span of y-values it covers.
From the graph, we can see that the span of y-values covered goes from y=-3 all the way to y=3.
However, note that at y=-3, while it is a closed circle, it is an open circle at y=3.
This means that we do <em>not</em> include y=3 in our range, but we <em>do</em> include y=-3 in our range.
So, our range is all values between -3 and 3 including -3.
In set notation, this is (and remember since this is the range, to use y):
So, our answer is D.
And we're done!
We will consider the following possibilities:
Wins none, wins first only, wins second only, wins both
a) Wins none:
Chances are: 75% x 65% = 48.75%
Thus, there is a 48.75% chance that the horse will sell at $15,000
b) Wins first only:
Chances are: 25% x 65% = 16.25%
c) Wins second only:
Chances are: 75% x 35% = 26.25%
Thus, the chances of the horse selling at $60,000 are 16.25 + 26.25
= 42.5%
d) Wins both:
Chances are: 25% x 35% = 8.75%
The chances that the horse will sell at $100,000 are 8.75%
