Answer:

-75 x^4 + 85 x^5 - 32 x^6 + 4 x^7

Step-by-step explanation:

$(x-5/2)^{2}(x-3)(x-0)^4 =0\\(2x-5)^{2}(x-3)(x)^4 =0$

Expand and get

Zx and Zy are supplementary angles. Zy measures<br> 156°<br> What is the measure of Zx?

cupoosta [38]

Answer:

Zx = 24 degrees

Step-by-step explanation:

since it is supplementary it adds up to 180 degrees. so you have part of the angle (156 degrees) so the equation would be 180 - 156 = Zx (origionally Zx + 156 = 180).

If (x, 9) is a solution to 5x - 2y = 12, what is the value of x ?

lina2011 [118]

X= 6

Explanation:

y=9 so rewrite the equation like this:

5x-2(9)=12

Multiply -2 by 9:

5x-18=12

Cancel out the -18:

5x-18=12
+18 +18

5x=30

Divide both numbers by 5:

5x/5 = 30/5

As an answer, you will get x=6:

Hope this helped:)

A pharmaceutical company interviews 12 people for eight openings in the research department of the company. 7 of the 12 people a

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

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