X = 7
y = 10
x + y = 700
7x + 10y = 6400
10x + 10y = 7000
(-) 7x + 10y = 6400
______________
3x = 600
x = 200
200 + y = 700
y = 500
Answer:
Step-by-step explanation:
The first answer a, is not a linear function because of the first term, 2√(x), this is basically 2(x^(1/2)) which means that it is not linear
B is linear because there are no exponents in any of the variables.
C is not linear because it forms a circle when graphed
D is linear because there are no exponents in any of the variables.
E is linear because there are no exponents in angy of the variables.
F is linear because there are no exponents in any of the variables.
G is not linear because it is a quadratic equation.
Answer:
Step-by-step explanation:
base x height divided by 2
4x3=12
12 divided by 2 = 6
6x5= 30
Answer:
C- y=2|x+2|
Step-by-step explanation:
When the number is inside the absolute value bars, the value shifts- so a positive two would move left two, and a negative two would move right two. If the number was outside of the equation, the shape would move up or down- a positive two would move the shape up two, and a negative two would move the graph down two.
