Answer:
$8
Step-by-step explanation:
This system of equations relates the ticket price, in dollars, for seats in the silver (x) and gold (y) sections at a rock concert. x + 2y = 82 3x + y = 96 By how much does the price of a ticket for the gold section exceed the price for a ticket for the silver section?
Two equations are presented in this question
x + 2y = 82 equation 1
3x + y = 96 equation 2
Multiply equation 1 by 3
3x + 6y = 246 equation 3
subtract equation 2 from 3
5y = 150
y = 30
Substitute for y in equation 1
x + 2(30) = 82
x = 82 - 60
x = 22
difference in price = 30 - 22 = $8
x =

Answer:
y= -2x -6
Step-by-step explanation:
the first thing is now we have 2 points which it ( -3 , -1 ) & (0 , -6 ) so we can use the formula of gradient to find the line's gradient.
formula of gradient : y2 - y1 / x2 - x1
after we find out the gradient of the line which is -2 and we can choose a point which is (-3,-0)/(0,-6) to sub into y = mx + c :
m = -2 , a point ( -3 , 0)
0 = -2 (-3) + c
0 = 6 + c
-6 = c
c = -6
now we rewrite it again the make the equation become complete : y = -2x - 6

The circle and the rectangle have the same area and we have the lenght and widht of rectangle, so we can discover rectangle area and it will be the same as circle.
A = 2πr . r/2
A = πr²
The answer will be B, because the circumference is 2πr and half a radius is r/2
And as shown: 2πr . r/2 = πr²
Answer:
3 ; 4/3
Step-by-step explanation:
x + 4(1/x) = 13/3
x + 4/x = 13/3
x^2 -13/3x + 4 = 0
3x^2 - 13x + 12 = 0
Δ = 169 - 144 = 25
x1 = (13 + 5)/6 = 3
x2 = (13-5)/6 = 4/3
