6x-7. It is this one because it says 7 less than which is -7. It also says 6 times the length of x which is 6x.
Answer:
Step-by-step explanation:
This will be solved using distance formula between two coordinates.
The distance formula between two coordinates is given as;
d =
Point T has coordinate of T(80,20)
Distance to Point U(20,60) is;
TU =
TU =
TU ≈ 72 Units
Distance From Point U(20,60) to Point V(110,85);
UV =
UV =
UV ≈ 93 units
I didn't bother to calculate TV because we are looking for shortest distance for the trip and by inspection if he goes from T to V first before Point U, it will be a longer journey.
Thus, shortest distance = TU + UV
shortest distance = 72 + 93 = 165 units

Answer:
Step-by-step explanation:
8x+5y = 20
y = (-8/5)x + 4
slope of the line is -8/5.
slope of any perpendicular to the line is ⅝.
line of slope ⅝ that passes through P(4,5):
y-5 = ⅝(x-4)
y = ⅝x + 2.5
find intersection of lines
⅝x + 2.5 = (-8/5)x + 4
25x + 100 = -64x + 160
89x = 60
x = 60/89, y = 260/89
distance between (60/89, 260/89) and (4,5) = 3.92
