What is the closest length for AC
a: 9 units
b: 12 units
c: 7 units
d: 8 units

8 units

Step-by-step explanation: Draw a diagonal Line from A to C. This is they hypotenuse of triangle ABC.

a^2 + b^2 = c^2

4^2 + 7^2 = 65^2

take the square root of 65^2 which is 8.0622... or approximately 8

2

step-by-step explanation:

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
