It’s c.
5(how many tickets) x 2(cost of one ticket) equals 10. 25(total amount of money)- 10(how much money the tickets cost in total) equals 15(the entry fee)
10 (how many tickets) x 2(cost of one ticket) equals 20. 35(total amount of money)- 20(how much money the tickets cost in total) equals 15(the entry fee)
it would be 60 then u find the factors to get to 60 and then after u find the factors that would be ur answer then u put sixty is the Lcm
Answer:
(0 , -a²)
Step-by-step explanation:
tangent at x = a and x = -a
y = x² (a , a²) and (-a , a²) must be on the curve and tangent to curve
gradient dy/dx = 2x
slope (m) at x = a is <u>2a</u> and slope (m') at x=-a is<u> -2a</u>
line1: (y - a²) / (x - a) = 2a
y - a² = 2a (x - a) y = 2ax - a² ... (1)
line2: (y - a²) / (x + a) = - 2a y = -2ax- a² ... (2)
(1) - (2): 4ax = 0 a≠0 x = 0
y = - a²
I wish I did it right, or ....
Answer:
irdk so ima say b
Step-by-step explanation:
Answer:
4
Step-by-step explanation:
we want y = mx + b
4x = 2y - 3
-2y = -4x - 3
2y = 4x - 3
therefore the gradient (slope) = the coeffecient of x, which in this case is 4
