Answer:
n^2 = n + 30
n^2 -n -30 = 0
Solving by quadratic formula
numbers equal 6 AND -5
DOUBLE -CHECK
6^2 -6 -30 = 0
36 -6 - 30 = 0 CORRECT
-5^2 - -5 -30 = 0
25 +5 -30 = 0 CORRECT
Two numbers 6 and -5
Step-by-step explanation:
Two negatives is a positive so the equation is Z+3/4=13/2
-3/4
Z=26/4-3/4
Z=23/4
Answer: A
Explanation: It’s A because 28,500 - 23,700 = 4,800. 4,800 / 3 = 1,600. 23,700 - 4,800 = 18,900 - 1,600 = $17,300. Hope this helps :)
The restaurant is 30*40= 1200 square feet
1 square meter is 10.76 sq feet
1200/10.76 ~=111.5
Assuming people are integers, the restaurant has a max seating capacity of 111
Lets write the given equation in the y = mx + c form
y - 4 = -2/3(x-6)
y - 4 = -2/3x + 4
y = -2/3x + 8
therefore the slope is -2/3 and intercept is +8
the perpendicular line passes through x = -2 and y = -2
then if the given graph has a slope of -2/3 the line that is perpendicular to that should have the reciprocal of the gradient and should be in the opposite direction. So m = +3/2
lets substitute x,y and m values for the new perpendicular line
y =mx + c
-2 = 3/2 * -2 +c
-2 = -3 +c
c = -2 +3
c = 1
Therefore the equation for the perpendicular line is
y = 3/2x + 1
