8x + y = 12 (substitute 3 for y)
<span>8x + 3 = 12 </span>
<span>8x = 9 </span>
<span>x = 9/8 </span>
<span>If y = 3 and 8x + y = 12, then x = 9/8.
HOPE THIS HELPS!!</span>
Number 4 and 6 are correct because you can only add variables with other variables so that is why 4 and 6 are correct
Answer:
A.Wind because it has the lowest predicted frequency.
Answer:
Yes , it is possible (see the explanation)
Step-by-step explanation:
we know that
In a right triangle, we have two complementary angles (their sum equal to 90 degrees)
so
If two angles are complementary, the cofunction identities state that the sine of one equals the cosine of the other and vice versa
<em>Example</em>
Suppose we have the right triangle ABC
The measure of angle C is 90 degrees
A and B are complementary angles
A+B=90°
therefore
sin(A)=cos(B)
sin(B)=cos(A)
