Which quadratic equation has roots - 2 and 1/5 :
Sladkaya [172]

Answer:

5 {x}^{2}  \:  +  \: 8x \:  - 2 \:  =  \: 0

Step-by-step explanation:

sum \: of roots =  - 2 +  \frac{1}{5}  = - \frac{8}{5}  \\ product \: of \: roots =  - 2 \times  \frac{1}{5}  =  -  \frac{2}{5}  \\ from \: general \: equation \\ a {x}^{2}  + bx + c = 0 \\  {x}^{2}  +  \frac{8}{5} x  \: -   \frac{2}{5}  = 0 \\ 5 {x}^{2}   \:  +  \: 8x \:  - 2 \:  =  \: 0

One day, a person went to a horse racing area. Instead of counting the number of humans an horses, he conuted 74 heads and 196 l
taurus [48]
X = the number of humans and y = the number of horses.

x+y=74
2x+4y=196

Because the number of humans and horses together is 74, and the total number of legs (2 per every human, x, and 4 per every horse, y) is 196.  Then, just use elimination to solve.



So, now that you have y, you can plug it into the first equation to find x:



So, x = 50 and y = 24, so there are 50 humans and 24 horses.
The correct answer is B.

Tanya made 75 flyers for five volunteers in her club to hang up around her school she gave 15 flyers to the first volunteer 22 f
AysviL [449]

Answer:

The remaining volunteers would get 11 flyers each.

Step-by-step explanation:

Given:

Total number of flyers = 75

Total number of volunteers = 5

Number of flyers for 1 volunteer = 15 flyers.

Number of flyers to 2nd volunteer = 22 flyers.

number of flyers to 3 volunteer = 16 flyers.

We need to find the remaining number of which are equally distributed in remaining number of volunteers.

Solution:

First we will find the number of flyers already distributed.

number of flyers already distributed is equal to sum of Number of flyers for 1 volunteer, Number of flyers for 2 volunteer and Number of flyers for 3 volunteer.

framing in equation form;

number of flyers already distributed = 15+22+16 = 53\ flyers

Number f flyers remaining is equal to Total number of flyers minus number of flyers already distributed.

Number of flyers remaining = 75-53= 22\ flyers

Number of volunteers remaining  =2

Now we will find number of flyers remaining each volunteers would get.

number of flyers remaining each volunteers would get is equal to Number of flyers remaining divided by Number of volunteers remaining.

framing in equation form we get;

number of flyers remaining each volunteers would get = \frac{22}{2}=11\ flyers

Hence the remaining volunteers would get 11 flyers each.

Suppose that in a sequence a2 = 14, a4 = 26, a6 = 38, a8 = 50, and a10 = 62. Which of the following is the explicit formula for
olya-2409 [2.1K]
Seems to be aritmetic
an=a1+d(n-1) is aritmetic
a1=fist term
d=comon difference
n=which term


a4-a2=2d where d is the common difference
26-14=12
12=2d
6=d
so
a2-6=a1
14-6=8

an=8+6(n-1)
expand
an=8+6n-6
an=6n+2
