7 + (-3x^2) for x = 0 7 + [-3(0)^2]; = 7 + -3(0); = 7 - 0; = 7
we know that
In a parallelogram opposite angles are congruent and consecutive angles are supplementary.
So
m∠O=m∠M
m∠L=m∠N
m∠O+m∠L=
Step 
Find the value of x

Step 
Find the value of angle L
m∠L
m∠L
m∠L
Remember that
m∠N=m∠L
m∠N=
therefore
the answer is
the measure of the angle N is equal to 
Hypotenuse by Pythagoras theorem = 407.83.
Answer:
285,000
Step-by-step explanation:
First, you need to figure out how much was profit. Multiply 300k by .05, which should give you 15,000. Then, subtract 15,000 from 300k to get 285k. hope this helps
The slope is -1 because the number beside x is always the slope and the y-intercept is 1 because the number being added or subtracted from x is always the y intercept
