Answer:
y = -1/3x + 4
Step-by-step explanation:
Perpendicular lines: Their gradients are reciprocals.
This means:
- -1 ÷ Gradient 1 = Gradient 2
- Gradient 1 * Gradient 2 = -1
Gradient of the given equation is 3.
-1 / 3 = -1/3
Gradient of the equation we're finding is -1/3
y = -1/3x + c
Substitute the coordinates in to find the value of c
2 = -1/3(6) + c
2 = -2 + c
2 + 2 = c
4 = c
y = -1/3x + 4
Answer:
1 & 1
Step-by-step explanation:
After 5 s, the particle traverses a path subtended by an angle of
(3π/4 rad/s) (5 s) = 15π/4 rad
Now, 15π/4 rad = 15/8 * 2π rad, so the arc has a length equal to 15/8 of the circumference of the path:
15/8 * 2π * (3 cm) = 45π/4 cm ≈ 35.3 cm
Answer:
The family bought 2 bags of chips
Step-by-step explanation:
Let the number of chips bags be = x
The number of candy bars = twice as much as the number of bags of chip
The number of candy bars = 2x
The total cost spent is = $5.50
Therefore cost of all the chips bags + candy bars = 5.50
2x + x = 5.50
3x = 5.50
x = 
x = 1.83
x = 2 (approx)
Thus the number of chips is 2 and the candy bars is 2(2) = 4 bags
Answer:
subtract first term from second term
c.d=T2_T1
c.d= -13-(-6)
c.d= -13+6
c.d= -7
