Answer:
The statement is incorrect because an inverse relationship between y and x would imply that the graph would be a downward curved graph whose slope changes rather than linear which has constant slope (see image).
Best to express this situation as:
There is a linear relationship between y and x with a negative constant slope. The keyword here is constant since the slope is the same in a linear relationship
Step-by-step explanation:
An inverse relationship exists between y and x when y is proportional to the reciprocal of y
This would be expressed in the form 
∝ 
As x decreases , y increases or vice-versa. It is often expressed in equation form as 
or 
where k is a constant and whose graph is curved in nature. The slope is changing for the range of x values not constant as would be the case for a linear graph
All we can say about the data is that there is a linear relationship between y and x with a negative constant slope
Answer: 3
Step-by-step explanation:
Solving for y right?
2y = 3x + 4 - x
2y = 2x + 4
y = 2x + 4 over 2
y = 2 (x + 2) over 2
y = x + 2
y - 3 = 2x - 6 over 2
y - 3 = 2(x - 3) over 2
y - 3 = x - 3
y = x
x - y - 2 = 2(2x + 1)
-y - 2 = 2(2x + 1) - x
-y = 2(2x + 1) - x + 2
y = -2(2x + 1) + x - 2
Answer:
x=9.9
Step-by-step explanation:
3= x/3.3
multiply by 3.3 on both sides
3(3.3)=x
9.9=x
There is actually a cool trick to this. When you see a and 2a, in this case 6 and 12, then the small triangle is a 60-30-90 triangle. The remaining side is
.
This value rounds down to 10, and yep, you guessed it, another 30-60-90.
This time, x =
.
This is a very difficult problem and requires knowledge of the special triangles. Hope this helps!
