Answer:
x = - 3.42443 or 6.42443
Step-by-step explanation:
If one shirt equals to $21.46, and you need to purchase 4 shirts to get the free pair of jeans, you multiply 4 by 21.46 and get 85.84. But if there is 42 customers taking advantage of the special, then you need to multiply 85.84 by 42, and you get 3,605.28.
Answer: y + 3 = 4 (x +1 )
Step-by-step explanation:
The eqution of a line in point- slope form is given as :
= m(
)
Where m is the slope and (
,
) is the given point
substituting the values into the formula , we have:
y - (-3) = 4 ( x - {-1) )
y + 3 = 4 ( x + 1)
This is the equation of the line in point-slope form.
To do this problem, you will need to know the side lengths of the triangle. If you have those, just plug them in for a, b, and c and evaluate the square root.
Here is an example. If the sides are 3, 4, 5.
It would be:

The 6 is in the formula because it is the semi-perimeter (half).
Answer:
x-2y-4
