To be a function, it has to pass the vertical line test, which means a vertical line drawn anywhere in the graph should cut the graph only once, not more.
To be a one-to-one function, it has to pass the vertical line test as well as the horizontal line test, which means that a horizontal line drawn anywhere in the graph should cut the graph only once, not more.
<em>Of course, it passes the vertical line test, so its a function. </em>
<em>Does it pass the horizontal line test? </em><em>NO! </em><em>As shown in the attached picture, the blue line (horizontal line) cuts the graph at 3 places. We therefore eliminate choices A and B. We can eliminate choice C because nowhere is it required a function to pass through the origin for it to be one-to-one. Hence, the answer is D (blue line shows this).</em>
<em>ANSWER: D</em>
Poor <span>Khianna. Let's help her out.
For the original recipe she needs </span>
cups of brown sugar but only has
So the fraction of the brown sugar she has is
She has to scale everything by a factor of
I won't multiply everything by 3/4 for you. 2 cups butter becomes 1 and a half cups butter, 1 tsp vanilla becomes 3/4 tsp, etc.
Answer:
c
Step-by-step explanation:
c because you would get fals as the answer because to solve you first distribute so you would get 3x+7=3x+6 and both 3 x's would cancel out so you would get 7=6 so that would be false
He saves $1253 per month.
Explanation: 65% of $3580 is $2327, meaning he spends $2327 per month. He has $1253 left over because $3580-$2327=$1253.
