WILL GIVE BRAINLIEST!!!!! PLS HELP ASAP!!!! 100 POINTS!!!!!!

PSYCHO15rus [73]

Answer:

the linear function gives us the points

(0,3)

(4,0)

(8,-3)

find the equation

find slope

(y2-y1)/(x2-x1)

for (0,3) and (4,0)

slope=(0-3)/(4-0)=-3/4

y=-3/4x+b

given

(0,3)

y=-3/4x+3

so sub -3/4x+3 for y in other equation

(-3/4x+3)^2+x^2=4

expand

9/2x^2-9/2x+9+x^2=4

11/2x^2-9/2x+9=4

times 2 both sides

11x^2-9x+18=8

minus 8 both sides

11x^2-9x+10=0

factor

or use quadratic formula

for

ax^2+bx+c=0

x=\frac{-b+/- \sqrt{b^2-4ac} }{2a}

−b+/−

−4ac

11x^2-9x+10=0

x=\frac{-(-9)+/- \sqrt{(-9)^2-4(11)(10)} }{2(11)}

2(11)

−(−9)+/−

(−9)

−4(11)(10)

x=\frac{9+/- \sqrt{81-440} }{22}

9+/−

81−440

x=\frac{9+/- \sqrt{-359} }{22}

9+/−

−359

we see we have no real roots

there are no intersection points

At one point in a Girl Scout cookie sales drive, region C had sold 1500 boxes of cookies, and region D had sold 1200 boxes of co

juin [17]

Answer:

a)After 6 days region D will catch region C

b) Region C will sell 13500 cookies and region D will sell 13600 cookies

Step-by-step explanation:

a) Cookies sold by region C more than region D= 1500-1200=300

But region D can sells 50 cookies every day i-e

50 cookies = 1 day

==> 1 cookie= 1÷50

==> 300cookies = 300÷50=6 days

So, after 6 days region D will catch up region C's

b) If sale stopped after 8 days;

Then sale of region C for 8 days = 1500×8=12000 cookies

so , total cookies sold = 1500 +12000=13500

For region D;

Before catching up region C cookies sold by region D = 1200

Till catching up region C - region D had also sold 1500 cookies,

and for 50 extra cookies than region C

next 8 days region D will sale =(1500+50)×8=1550×8=12400 cookies

So, total number of cookies sold by region D = 1200+12400=13600
