Answer:

Step-by-step explanation:

hello :

you have this system :      y=2x²-12x+20

                                          y=2

means :   2x²-12x+20 =2

2x²-12x+20-2 =0

2x²-12x-18 =0        a=2  and b= -12   and c= -18

delta = b²-4ac

delta = (-12)²-4(2)(-18)

delta = 0

X1 =X2 = -b/2a =12/4 =3

the solution point is : (3 ; 2)

Simone used 2 1/3 kilograms of flour to bake a cake . She used 4/5 kilograms of flour more to bake a second cake. How much flour
Likurg_2 [28]

Answer:

3.13 kilograms used for the second cake

Step-by-step explanation:

because the fractions have different denominators you have to multiply the denominators together to figure out what to change them too. but instead you can just figure out what the decimal for each is. 1/3 is 0.33, and 4/5 is 0.80. all you do is add these together to get 1.13. so now all you do is add 2+1.13 to get 3.13.

How do you get the answer to 10+12y=2y+40
stepladder [879]
Y = 3

Exp:

10 + 12y = 2y + 40
- 2y = - 2y

10 + 10y = 40
-10 -10

10y = 30
/ 10 / 10

y = 3
