Answer:

-3 and 5

Step-by-step explanation:

f(n) = n² - 2n - 15

numbers whose product is -15 and sums up to -2 = -5 and 3

= n²- 5n+3n - 15

= n(n - 5) +3 (n - 5)

f(n) = (n + 3)( n - 5)

n + 3 = 0 n - 5 = 0

n = -3 n = 5

Roots = -3 and 5

Write an equation in slope intercept form of the line that passes through the given point and is parallel to the graph of the gi

kupik [55]

For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

$y = mx + b$

Where:

m: It is the slope of the line

b: It is the cut-off point with the y axis

We have the following line:

$y = 2x-8$

The slope is $m_ {1} = 2$

By definition, if two lines are parallel then their slopes are equal. Thus, a line parallel to the given line will have a slope $m_ {2} = 2$

Therefore, the equation of the parallel line will be of the form:

$y = 2x + b$

We substitute the given point and find "b":

$3 = 2 (-1) + b\\3 = -2 + b\\3 + 2 = b\\b = 5$

Finally, the equation is:

$y = 2x + 5$

Answer:

$y = 2x + 5$

A survey of a random sample of voters shows that 29% plan to vote for Martin and 71% plan to vote for

Iteru [2.4K]

Range=±7%

Martin=71%, Lang=29%

Range for Martin=71%±7%

So, highest %=71%+7%=78%

Lowest %=71%-7%=64%

Therefore,range for Martin is between 64%-78% which is 14%
