A linear relationship is an equation that has a constant slope
The equation that does not represent a linear relationship is (b) y = 2x^2 + 5x
<h3>How to determine the non-linear relationship</h3>
A linear equation can take any of the following forms:
y = mx + b
y - y1 = m(x - x1)
Ax + By = c
Any form different from the above forms is not a linear equation
Using the above format as a guide, the equation that does not represent a linear relationship is (b) y = 2x^2 + 5x

The answer is <span>c. 25
</span>
<span>sin(ϴ + 15) = cos(2ϴ)
</span>sin(ϴ + 15) =sin(25 + 15) =<span>sin(40) =0.64
</span>cos(2ϴ)=cos(2x25)=<span>cos(50)=0.64
</span> so <span>ϴ=25</span>
Answer:
-7.6
Step-by-step explanation:
Use the equation p=2l+2w and sub everything in to get 280=2l+2(l+12).
distribute the 2 for 280=2l+2l+24.
add/subtract like terms over, leaving you with 256=4l.
divide the 4 from 256, resulting in l=64.
since w=l+12, add 12 to 64 to find that w=76.
basically, l=64 and w=76.
hope this helps!
