Write out all the pairs of numbers which can be multiplied to produce c.
Add each pair of numbers to find a pair that produce b when added. ...
If b > 0, then the factored form of the trinomial is (x + d )(x + e). ...
Check: The binomials, when multiplied, should equal the original trinomial.

in a class of 50 students 15 are girls.five girls and 2/7 of the boys were chosen to play a match .the total number of students
Aleks [24]

Answer:

15 students

Step-by-step explanation:

No. of boys students = No. of all students - No. of girls

no. of boys =50-15 = 35 boys

the boys that will play the match are 2/7 of boys = (2/7)x35 = 10 boys

and the girls that will play the match are 5 girls

so, no of students chosen to play = 5+10=15 students

The amount​ (in megawatts) of energy generated in a country from wind power can be modeled by the function ​W(t)equalsw0​(1.90​)
Ad libitum [116K]

Answer with Step-by-step explanation:

We are given that

W(t)=W_0(1.90)^t

Where t corresponds to the year 2000=0

a.W(0)=2540MW

Substitute the values

2540\times 10^6=W_0(1.90)^0=W_0

W_0=2540MW

b.In  2004

t=4

W(4)=2540(1.90)^4

W(4)=33101.534 MW

c.In 2013

t=13

W(13)=2540(1.9)^{13}=10.68\times 10^6MW

Which shows the correct substitution of the values a, b, and c from the equation 0 = – 3x2 – 2x + 6 into the quadratic formula?
lbvjy [14]

Answer:

x = StartFraction negative

(negative 2) plus or minus StartRoot (negative 2) squared minus 4 (negative 3)(6) EndRoot Over 2(negative 3) EndFraction

Step-by-step explanation:

0 = – 3x2 – 2x + 6

It can still be written as

– 3x2 – 2x + 6 =0

Quadratic formula=

-b+or-√b^2-4ac/2a

Where

a=-3

b=-2

c=6

x= -(-2)+ or-√(-2)^2-4(-3)(6)/2(-3)

x = StartFraction negative

(negative 2) plus or minus StartRoot (negative 2) squared minus 4 (negative 3)(6) EndRoot Over 2(negative 3) EndFraction

Answer:

It's the second answer

Step-by-step explanation:

A(7,5) B(-4,-1)

y-yA/yB-yA= x-xA/xB-xA

y-5/-1-5=x-7/-4-7

-11y+55=-6x+42

-11y=-6x-13

y=6/11×+13/11
