Answer:
C
Step-by-step explanation:
A triangle must have three angles that add up to 180 degrees.
40 + 70 + 65 = 175, which is not 180, so it cannot create a triangle.
15a is non-exponential because the variable is not in the exponent
Instead, this is a polynomial function. It can also be called a power function as power functions are in the form a*x^b where 'a' and 'b' are fixed numbers.
To find the inverse, turn the equation into x=4y-7 and solve for y. The inverse would be y=1/4x+7/4, or f(x)=1/4x+7/4. I hope this helps!

Step-by-step explanation:
Since we have given that
Time taken by steamboat makes the trip=5 hours
Time taken by yacht makes the trip =2.5 hours
Since we have also given that
the yacht is 20 knots faster than the steamboat,
So let the speed of steamboat be x
Let the speed of yacht be x+20
Now, we have given that both boats will travel the same distance ,
So,

Hence,
