<h2>Answer:</h2>

a = 2, b = -18, c = 40

<h3>Step-by-step explanation:</h3>

$Given:\ Polynomial\ f(x)=ax^2+bx+c\ has\ zoroes\ 4\ aud\ 5$

$and\ f(-1)=60$

$Tofind:\ a,\ b,\ c$

$Solution:\ As\ 4\ and\ 5\ are\ zeroes\ so\ f(4)=f(5)=0$

$f(4)=a(4)^2+b(4)+c=0\Rightarrow16a+4b+c=0-(1)$

$f(5)=a(5)^2+b(5)+c=0\Rightarrow25a+5b+c=0$

$f(-1)=a(-1)^2+b(-1)+c=60\Rightarrowa-b+c=60-(3)$

$subtracting\ (1)\ from\ (2)$

$25a+5b+c-(16a+4b+c)=0\Rightarrow9a+b=0\Rightarrowb=-9a$

$subtracting\ (3)\ from(2):$

$25a+5b+c-(a-b+c)=0-60\Rightarrow24a+6b=-60$

$putting\ b=-9a$

$24a+6(-9a)=-60\Rightarrow24a-54a=-60\Rightarrow-30a=-60$

$a=\frac{-60}{-30}=2$ $\Rightarrow$ $a=2$

$b=-9a=-9\times2=-18$

$c=-a+b\neq60=-2-18+60=-20+60=40$

A baker uses 84 cups of flour for 36 batches of cookies. How many cups of flour are needed for 1 batch of the cookies?.

garik1379 [7]

Answer:

23/10

Step-by-step explanation:

To find the unit rate divide 84 by 36

84 ÷ 36 = 2.3

To convert 2.3 to a faction

2.3 = 2.0 + 0.3

0.3 = 3/10

3/10 + 2 = 2 3/10

2 3/10 = 23/10

James and Aaron run cross country. James has already run 6 miles this month and plans to run 3 miles each day over the next seve

ahrayia [7]

Answer:

Step-by-step explanation:

Step one:

for James

the initial mile covered= 6miles

the planned number of miles per day= 3miles

let the number of days be x

and the total distance in miles be y

the total distance for the x days day will be

y=6+3x------------1

step two:

for Aaron

the planned number of miles per day= 4miles

let the number of days be x

and the total distance in miles be y

the total distance for the x days day will be

y=4x------------2

The system of equations is

y=6+3x--2

y=4x----2

Step three:

for the number of days that Aaron needs to run to meet up with James, we need to equate the two equations to find x which is the solution

6+3x=4x

6=4x-3x

x=6days

This means that Aaron will have to run at 4mile per day consistently for 6 days to meet up with James
