3 (-3^2 × 1^5) + 4 (-3 - 8)^2
3 (9 × 1) = 27 + 4 (121) = 484
27 + 484 = 511
Answer:
The answer is B
Step-by-step explanation:
You would plug in 1 wherever there is an x in the equation
Answer:
54 km per hr
270 km
Step-by-step explanation:
1 metre per second is 3.6 km per hour.
15*3.6=54 km per hour
distance covered in 5 hrs=54*5=270 km
115°
A triangle is 180° so add the two degrees given and subtract that from 180; 180-(75+40)
180-155= 65. then a line is 180 degrees so you subtract 65 from 180 and get 115
Slope formula : slope = (y2 - y1) / (x2 - x1)
(2,3)...x1 = 2 and y1 = 3
(4,2)... x2 = 4 and y2 = 2
now we sub and solve
slope = (2 - 3) / (4 - 2) = -1/2 <==
