Answer:

Step-by-step explanation:

slope intercept form => Y = mx + b

find m... the slope by using any two points on the line

p1 = (0,5) by inspection

p2=(4,6) by inspection

find m = y2-y1 / x2-x1

m = 6 - 5 / 4 - 0

m =1 / 4

then use the slope intercept formula

y = 1/4x + 5 for your answer. we know b = 5 b/c thats where the line crosses the y axis.

y = $\frac{1}{4}$ x + 5 is the answer

Determine algebraically whether the function is even, odd, or neither even nor odd.

kobusy [5.1K]

The function is odd just substitute f(x) for f(-x) and replace all the x's with -x's then go back to the original problem and substitute f(x) for -f(x) and multiply the original problem by -1 and since f(-x) and -f(x) are equal, it is odd. if the original problem, f(x) and f(-x) were equal it would be even and if none of the three are equal it would be neither. the answer to this question is odd because f(-x) and -f(x) are equal.

viva [34]

Answer:

(a) 495, (b) 210

Step-by-step explanation:

Total number of persons = 12

number of openings = 8

number of women = 7

number of men = 12 - 7 = 5

(a) Number of ways to select the 8 persons

$C_{8}^{12}\textrm{}\\\\= \frac{12!}{8!\times 4!}\\\\=495$

(b) Three are men

So, 3 men and 5 women

The number of ways are

$C_{3}^{5}\textrm{} \times C_{5}^{7}\textrm{}\\\\= \frac{5!}{3!\times 2!}\times \frac{7!}{5!\times 2!}\\\\=210$

Morgarella [4.7K]

Answer:

x = 0

Step-by-step explanation:

here's the solution :-

=》 -13x - 2 = -10x - 2

=》 -13x + 10x = -2 + 2

=》 -3x = 0

=》 x = 0 ÷ -3

=》 x = 0

13. if edward wins 6 of his remaining games...that would make a total of 12 wins (since he already won 6 earlier)

3/4 as many winsa as edward....3/4(12) = 36/4 = 9...so he would have to win 9 to have 3/4's as much as edward...and howard has already won 4...so he needs (9 - 4) = 5....he needs 5 wins
=======================
14. Robert has already won 2, and he has lost 8...so he would have to win at least 7 of his games to have more wins then losses
