Since it is a square, the angles are 90 degrees. The diagonals would bisect the angle in half so the angle PRS would be equal to 45 degrees.
Basically find the eqatuions of the lines that produce the shaded reigon
so find the lines first
we notice taht they must be inequalities
the upward line is dotted so it must have > or <
ok, hum the slope seems to be -3
the y intercept is 1 so the euaiton is y_-3x+1
the blank is the inequality
ok, test a point
(0,0) is in it
0_-3(0)+1
0_1
0<1
so it is y<-3x+1
secondn line
solid line so ≤ or ≥
slope of 2
y intercept of -1
y_2x-1
(0,0) is a possible solution
test it
0_2(0)-1
0_-1
0≥-1
so the equations are
y<-3x+1 and y≥2x-1
a. the system is y<-3x+1 and y≥2x-1
b. a solution is (0,0) because it is in the shades reigon which is the intersection of the 2 inequalities
46.6 billion
explanation:
Isolate S on the left side by adding 1.9x to both sides. this gives you S = 4.8 + 1.9x. Plug in 22 for x because 2020 is 22 years from 1998.
4.8 + 1.9(22) = 46.6
3.99-1 = 2.99 they lose 2.99 per burger
Multiply the number of people by the amount lost per burger:
2.99 x 86,047 = 257,280.53
They would lose: $257,280.53
Answer:
the last option is the correct one
