5 points
jonny [76]

keeping in mind that parallel lines have exactly the same slope, let's check for the slope of the equation above

y = \stackrel{\stackrel{m}{\downarrow }}{2}x-5\qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}

so we're really looking for the equation of a line whose slope is 2 and passes through (4 , -3)

(\stackrel{x_1}{4}~,~\stackrel{y_1}{-3})\qquad \qquad \stackrel{slope}{m}\implies 2 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-3)}=\stackrel{m}{2}(x-\stackrel{x_1}{4}) \\\\\\ y+3=2x-8\implies y=2x-11

If brooklynn an cook 11 pies in one day how many can she cook in a year.
Aleks [24]
If she was really committed and wanted to bake 11 pies every day for a year, she would be able to make 11•365 pies. Unless it's leap year. Then she would be able to make 11•356 pies.

PLEAAASE ANSWER TIMER IS RUNNING OUT
lisabon 2012 [21]

Answer:

the correct answer is 1/2.

How i came to this answer was adding all of the number of medals together for all of the years, coming up to a total of 22. When asking about probability of any given set or amount of things, you always take the selected values and take them out of the whole amount. Years 2009 and 2012 have a whole selected value of 11 (4+7). Therefore you're "taking" 11 from 22, coming up with the fraction 11/22 seeing as that is not a answer choice the next step is to simply the fraction to 1/2.

Which of the following disjunctions is false ?
notsponge [240]
A disjunction is false if both parts of the disjunction are false; otherwise, it is true
----------------------------------------------
Choice A

4-3=2 is false
6*3=9 is false

both parts are false, so overall the entire disjunction is false
----------------------------------------------
Choice B

5*6=30 is true
3+4=7 is true

Neither part is false, so overall the entire thing is true
----------------------------------------------
Choice C

8+3=11 is true
5*4=23 is false

While second piece is false, the overall disjunction is true. The first part (true) makes the whole thing true.
----------------------------------------------
Choice D

7+6=13 is true
5*2=10 is true

Neither part is false, so overall the entire thing is true
----------------------------------------------
----------------------------------------------
In summary, we have

A. False
B. True
C. True
D. True

Making choice A the only answer that is false. So choice A is the final answer
