Helena wrote the equation using point-slope form for the line that passes through the points (5, 1) and (3, 5). Analyze the step

s of her work using the point-slope form to write the equation.
1. m = StartFraction 5 minus 1 Over 3 minus 5 EndFraction = StartFraction 4 Over negative 2 EndFraction = negative 2. 2. y minus 1 = negative 2 (x minus 3). Y minus 1 = negative 2 x + 6. y minus 1 + 1 = negative 2 x + 6 + 1. 3. y = negative 2 x + 7.

In which step did Helena make an error?
In step 1, she substituted the x values for y and the y values for x.
In step 2, she didn’t use an x and y from the same coordinate pair.
In step 3, she solved for the wrong variable.
Helena did not make an error.

luda_lava [24]

Question:

Read the excerpt from Julius Caesar, act 1, scene 2.

CASSIUS: ‘Tis just; And it is very much lamented, Brutus, That you have no such mirrors as will turn Your hidden worthiness into your eye, That you might see your shadow. I have heard 5 Where many of the best respect in Rome– Except immortal Caesar‐speaking of Brutus, And groaning underneath this age’s yoke, Have wished that noble Brutus had his eyes.

BRUTUS: Into what dangers would you lead me, Cassius, 10 That you would have me seek into myself For that which is not in me?  

CASSIUS: Therefore, good Brutus, be prepared to hear. And since you know you cannot see yourself So well as by reflection, I, your glass, 15 Will modestly discover to yourself That of yourself which you yet know not of.

Answer:

The correct choice is D)

Explanation:

Cassius speaks of Brutus as one who is unable to see or know his own value and presumes to help him therewith. He does this by pointing out that many of the well respected people in Rome wish that he were in Caesars shoes as King.

Cheers!

.580 80 repeating as fraction
denis-greek [22]
First off, we'll move the non-repeating part in the decimal to the left-side, by doing a division by a power of 10.

then we'll equate the value to some variable, and move the repeating part over to the left as well.

anyhow, the idea being, we can just use that variable, say "x" for the repeating bit, let's proceed,

\bf 0.580\overline{80}\implies \boxed{\cfrac{5.80\overline{80}}{10}}\qquad \textit{now, let's say }x= 5.80\overline{80}\\\\&#10;-------------------------------

\bf thus\qquad \begin{array}{llll}&#10;100\cdot x&=&580.80\overline{80}\\&#10;&&575+5.80\overline{80}\\&#10;&&575+x&#10;\end{array}\qquad \implies 100x=575+x&#10;\\\\\\&#10;99x=575\implies x=\cfrac{575}{99}\qquad therefore\qquad \boxed{\cfrac{5.80\overline{80}}{10}}\implies \cfrac{\quad \frac{575}{99}\quad }{10}&#10;\\\\\\&#10;\cfrac{\quad \frac{575}{99}\quad }{\frac{10}{1}}\implies \cfrac{575}{99}\cdot \cfrac{1}{10}\implies \cfrac{575}{990}\implies \stackrel{simplified}{\cfrac{115}{198}}

and you can check that in your calculator.

A football quarterback goes for a two-point conversion when the ball is within 10 yards of the end zone. During the game, he has
Crank

Answer:

P=0.075,          P=7.5\%

Step-by-step explanation:

We look for the probability that the player fails the first attempt and also fails the second attempt.

We know that the probability that the quarterback fails the first attempt is:

P(1) = 0.5

We know that the probability that the quarterback fails the second attempt after failing the first is:

P(2|1) = 0.15

Then the probability of failure of both attempts is:

P(2|1)=\frac{P(1\ and\ 2)}{P(1)}

P(1\ and\ 2)=P(1)*P(2|1)

P(1\ and\ 2)=0.5*0.15

P(1\ and\ 2)=0.075
