Answer:
Yes
Step-by-step explanation:
y=3.7x starts with a (0,0) and it is a straight line nonetheless.
It isn't zig zag line and is a proportional relationship.
Answer:
The correct options are:
- g(x) is shifted three units higher than f(x).
- g(x) has a period that is half the period of f(x).
Step-by-step explanation:
We have to compare the graphs of the function:

and 
We have to select the correct options among the following:
As we know that the period of sine function is 2π.
i.e. Period of function f(x) is: 2π.
The period of sin(2 x) is π.
Hence, the period of the function g(x) function is π.
- Hence, the period of g(x) is half the period of f(x).
- Also we could observe that g(x) is shifted 3 units upward.
The independent variable is the number of sweatshirts sold so it is answer A.
(Money raised is the dependent variable because it depends on the number of sweatshirts sold.)
Slimination
multiply first equaiton by 2
2x+6y=10
add to second equiaotn
2x-2x+6y-6y=10-10
0=0
this is true so therfor they are the same equaiton
so solve
x+3y=5
3y=-x+5
y=-1/3x+5/3
subsituter values for x and get valuse for y
if x=2 then y=1
B and c are correct because you use divison and multiplication to get the right answer and the right answer is 99cm
