Answer:
Choice C
Step-by-step explanation:
First when we are looking for a system of equations that has no solution we are looking for two lines that won't intersect and the only lines that would never intersect are parallel lines.
Ok so what we are looking for is an equation with the same slope but different y-intercept. A parallel line should go at the same rate like the other line but shouldn't start at the same point.
<em><u>Analysing Choice A:</u></em>
We just said that the slope has to be the same so this one can't be it.
<em><u>Analysing Choice B:</u></em>
For this one we have to put it in slope-intercept-form.
So we see that the slope is the same for this one and and the y-intercept is also the same which is NOT what we need so on tho the next one.
<em><u>Analysing Choice C:</u></em>
For this one we also have to put it in slope-intercept-form.
We see that the slope are the same and the y-intercept are different so this is the one we are looking for.
Sorry but for the sake of time I won't analyze choice D.
Answer:
Antonio's first error occurred in First step where he added the denominators of both fractions instead of finding a common denominator.
Step-by-step explanation:
In order to add or subtract two fractions, a common denominator is found and then the denominators of both fractions are made equal to the common denominator.
The given fractions are:
The common denominator is the number which is the multiple off denominators of both fractions involved.
Antonio made his first error in first step. Instead of finding a common multiple denominator, he add the denominator of both fractions which is wrong.
The correct method is:
Hence,
Antonio's first error occurred in First step where he added the denominators of both fractions instead of finding a common denominator.
Answer:
In 24 turns , both players will have 216 points.
Hope this helps , if you need explanation please tell me!
Step-by-step explanation:
Roots:
(-3,0) (1,0)
Turning point:
(-1, -4)
<em>A - B = 4</em>
<em>A + B = 64</em>
<em>__________ + </em>
<em>A - B + A + B = 64 + 4</em>
<em>2A = 68</em>
<em>A = 34</em>
<em>B = 34 - 4</em>
<em>B = 30</em>
