I must make some assumptions here about what you may have meant by your "<span>linear equation y=3x−5y=3x−5 y equals 3 x , minus 5."
You've written "y=3x-5" three times on the same line of type. Why is that?
Let's change what you've typed to the following:
</span><span>linear equation y=3x−5
separate linear equation y equals 3x minus 5, or y=3x-5
Please go back and ensure that you have copied down this problem precisely as it was originally presented. Be careful not to duplicate info (as you did in typing "y=3x-5," followed by "</span><span>y equals 3 x , minus 5."
</span><span>
y = 3x - 5 is, as you say, "a linear equation." The slope of this line is 3 and the y-intercept is (0, -5).
As to form: This is a "slope-intercept equation of a straight line."
Other forms include "General form of the equation of a straight line," "Point-slope form."</span>
Foil the equation; j*k, j*-5, 7*k, 7*-5, once you foil add like terms.
jk - 5j +7k - 35 is the final answer
The next number should be 297.
Full question:
Every 5 years the Conference Board of the Mathematical Sciences surveys college math departments. In 2000 the board reported that 51% of all undergraduates taking Calculus I were in classes that used graphing calculators and 31% were in classes that used computer assignments. Suppose that 16% used both calculators and computers. a) What percent used neither kind of technology? b) What percent used calculators but not computers? c) What percent of the calculator users had computer assignments? d) Based on this survey, do calculator and computer use appear to be independent events? Explain.
Answer:
a. 34%
b. 35%
c. 31.4%
d. Independent events
Explanation:
a. To calculate percentage that used neither kind of technology, we already know those that use the technologies and total taking calculus so:
100%-51%-31%-16%= 34%
b. Percentage that used calculators but not computers.
= 51%-16%=35%
c. Percentage of the calculator users that had computer assignments?
= 16/51×100=31.4% (there are 16 people using both so that as a percentage of 51 people using calculators)
d. Independent events are events that do not affect the other, such that occurrence of one does not define occurrence of the other. Since percentage of calculator and computer assignment users is close to those who are not using any, we can say they are independent events.
