X-the number
6(x + 12) = 40 |use distributive property: a(b + c) = ab + ac
6x + 72 = 40 |subtract 72 from both sides
6x = -32 |divide both sides by 6
x = -32/6
x = -16/3
x = -5 1/3
Where is table y?
Considering that Livia eats chicken drumsticks with 11 grams of protein and cheese sticks with 7g of protein, we can determine that for each chicken drumstick, she will receive 11 grams of protein.
For each cheese stick, she will eat 7g of protein.
If she eats 10 cheese sticks, she will eat 70 gram of protein.
This funciton is dependent on the amount of cheesesticks she's eaten.
Answer:
d
Step-by-step explanation:
Use the quadratic formula, x=

(don't know how to type the "-"sign in the formula, so there is only the "+" in the formula)
in this case, a=1, c=34, b is unknown
from the roots, we can tell that -b+

=2(5+3i)=10+6i
Note: the original equation already give b as -b, so -(-b)=10, b=10
using b^2-4ac=(6I)^2,
b^2-4*34=-36
b^2=100
you will also get b=10
Hello,
y-3x=2==>x=(y-2)/3
==>(x+1)²=((y-2)/3+1)²=(y+1)²/9
y=(x+1)²-5
==>y=(y²+2y1)/9 -5
==>y²-7y-44=0 ; Δ=7²+4*44=225=15²
==>y=(7+15)/2 or y=(7-15)/2
==>y =11 and x=(11-2)/3=3
or y=-4 and x=(-4-2)/3=-2
