Answer:
D
Step-by-step explanation:
4.10pm-1.55pm
=3.70pm-1.55pm
=2hr15min
4x + 2y = 20 in slope intercept form would be y = 2x + 10
$12. The initial entry fee is $6 and every ride is $2. 2x3=6 and 6+6=12.
X= -4; f(x)= -15
X= 2; f(x)= 3
X=5; f(x)= 12
Y = -3/4x + 5.....the slope here is -3/4...but for a perpendicular line, we need the negative reciprocal slope. All that means is " flip " the slope and change the sign. So the slope we need is 4/3 (see how I flipped the slope and changed the sign)
now we use y = mx + b
slope(m) = 4/3
(3,-1)...x = 3 and y = -1
now we sub and solve for b, the y int
-1 = 4/3(3) + b
-1 = 4 + b
-1 - 4 = b
-5 = b
so ur perpendicular line is : y = 4/3x - 5
