Answer:
For the pre-rax subtotal x you have this equation
x + 0.074x = 408.12 dollars.
x*(1 + 0.074) = 408.12
1.074x = 408.12 ====> x = 408.12%2F1.074. 408.12/1.074
Step-by-step explanation:
That one i believe would be A
Slope form is y/x
to find this subtract -5, 7 by -3, 5 to get
-2, 2 and putting it in slope format....2/-2 which would be -1 or just -x (means -1x)
so far we've found out.....y = -x (+b)
b is what we need to find now so... plug in one of the coordinates
7=5+b (5 because --5 is positive 5)
b=2
so FINALLY the equation would be y = -x + 2
Answer:
The exact solution is

And the approximation to three decimal places is:
x = 0.363
Step-by-step explanation:
Here we have the equation:

Now we can remember a property of the natural logarithm function:
Ln(a^n) = n*Ln(a)
Now we can apply the Ln( ) function to both sides of that equation to get:

Then we get:

Solving that for x we get:

So the exact solution is:

And the approximation to three decimal places is:
x = 0.363
Answer:
All Triangles are closed figure polygons that have three straight sides
Step-by-step explanation:
All 2D shapes are plane figures so this one is false. Three right angles are greater than 180 so this is fake. Polygon and closed figures are shapes with three or more closed sides. And triangles have straight sides.
