Answer:
x= -7 x = -4
Step-by-step explanation:
x^2 + 11x + 28 = 0
What two numbers multiply to 28 and add to 11
7*4 = 28
7+4 =11
(x+7) (x+4) =0
Using the zero product property
x+7 =0 x+4 =0
x= -7 x = -4
Answer:
Given that Justin is collecting data on reaction time, what type of data is he working with? Reaction time is continuous quantitative data because it is obtained by measuring and is not limited to a certain set of numbers.
From the second:
2x-y=4
x=(4+y)/2 and applying this to first:
4+y+3y=12
4y+4=12
4y=8
y=2 and since x=(4+y)/2, x=3 so
x+y=2+3=5
