Answer:
I am in 7th grade so stop asking me questions for
Step-by-step explanation:
2 necklaces x $3.80 for each bead
$7.60
15.40 - 7.60
7.80
7.80 divide by 2
$3.90 for each pendant
To solve this system, we can use substitution.
x + 6y = 61
x = 61 - 6y
Now we substitute into the other equation.
4 (61 - 6y) - 5y = -17
244 - 24y - 5y = -17
244 -29y = -17
29y = 261
y = 9
Now we find x.
x + 6 (9) = 61
x + 54 = 61
x = 7
That means the solution to this system is (7, 9)
3) 5x-18=3x+2
2x-18=2
x=10
I’m not sure but hope it’s right.
Lets find the equation that represents that relationship:
y = zx^2
plug in data:
18 = z(6)^2
18 = z(36)
z = 1/2
then the equation is:
y = (1/2)x^2
now you just have to plot that equation
