HELP ASAP IM STRUGGLING : The instructions on a box of chicken patties state that one patty should be cooked for 2.5 minutes in
AveGali [126]

Answer:

y= 1.5x + 2.5

Step-by-step explanation:

So slope intercept form is y= mx + b.

y is the number of minutes, so that will be on the left of the equal sign, not part of the math side of the actual equation, because it's the answer.

1.5x is the mx part because it's 1.5 minutes for each extra patty. So that would explain the x attached to it. so for each extra patty you add, that's what x would be.

The + 2.5 at the end, is just the time for the initial patty.

Hope this helps and is easy to understand! :)

Find the length of AB?
vampirchik [111]

Given:

The figure of a right triangle.

To find:

The length of AB.

Solution:

In a right angle triangle,

\cos \theta=\dfrac{Base}{Hypotenuse}

Using this trigonometric ratio for the given triangle, we get

\cos A=\dfrac{AB}{AC}

\cos (60^\circ)=\dfrac{AB}{10}

\dfrac{1}{2}=\dfrac{AB}{10}

\dfrac{1}{2}\times 10=AB

5=AB

Therefore, the length of AB is 5 units.
