Answer:
The answer is 5.5, 6.0 and 8.0
Since 2x+y>4 you get y>4-2x. Then you draw the line y=4-2x then you are interested in everything above the line not including it since it is y>4-2x so it is a dashed line. You need to shade the side that satifies the inequality and since it is every pair (x,y) where y>4-2x, you need to shade everything above the line which is the side that does not include the origin. So the answer is C.
Answer:
A) 7x^2-7x+15
Step-by-step explanation:
f(x) = 4x2 - 5x + 7,
g(x) = 3x2 - 2x + 8
f(x) +g(x) =
4x^2 - 5x + 7 + 3x^2 - 2x + 8=
7x^2-7x+15
Answer:
First: 12 feet
Second: 11 feet
Third: 14 feet
Step-by-step explanation:
Let the second side of the traingle be x
First side of the triangle= x+1
Third side of the triangle= x+3
x+x+1+x+3 = 37
3x+4 = 37
3x = 37-4
3x = 33
x = 11
First side of the triangle= (11)+1
= 12
Second side of the triangle= 11
Third side of the triangle= (11)+3
= 14
