1) the vertex of a parable is given for two points, ( -b/2a, -b2-4ac/4a)
2) Now substitute the values in the equation
x = - (-8)/2(-2) = 8/ -4 = -2
y = -(8^2-4(-2)(1)/ 4(-2) = -(64-8) /-8 = 56/8 = 7
v(-2,7)
Answer:
9m
Step-by-step explanation:
volume = length x width x height so
432 / 12 / 4 = 9
Step-by-step explanation:
y +2= 5(x+9)
y + 2 = 5x + 45
y = 5x + 43
Answer:
7(x times y)
Step-by-step explanation:
Product means multiply, so it wants you to multiply two numbers and multiply THAT by 7. So we will use two variables, in this case, I will use x and y. X times y. 7 Times that.
