Answer:
See below.
Step-by-step explanation:
There is an infinite n umber of systems of equations that has (1, 4) as its solution. Are you given choices? Try x = 1 and y = 4 in each equation of the choices. The set of two equations that are true when those values of x and y are used is the answer.
Answer:
36
Step-by-step explanation:
The maximum height is the y-coordinate of the vertex
given a quadratic in standard form : ax² + bx + c : a ≠ 0
then the x-coordinate of the vertex is
= - 
y = - x² + 20x - 64 is in standard form
with a = - 1, b = 20 and c = - 64, hence
= -
= 10
substitute x = 10 into the equation for y
y = - (10)² + 20(10) - 64 = 36 ← max height
M 7=280. you just multiply 7 by 40 to get your answer. i am pretty sure.
Answer:
16 17 18 19
Step-by-step explanation:
x+(x+1)+(x+2)+(x+3)
3rd and 4th: (x+2)(x+3) = 2x+5
2x+5 = 37
2x = 32
x=16
