Answer:
y = - 3x -11
Step-by-step explanation:
(x₁ , y₁) = (-2 , -5) & m = -3
y - y₁ = m (x - x₁)
y - [-5] = (-3)(x -[-2])
y + 5 = (-3)(x + 2)
y + 5 = -3x - 6
y = -3x - 6 - 5
y = - 3x -11
Answer:
It's D (a = 20 because the rate of change is –3.)
Step-by-step explanation:
I did the test and that was the correct answer
The answer is 6y^3+17y^2+22y+15
Answer:
Option A
A B C D
Step-by-step explanation:
Line of symmetry means that line which cut anything into two two halves.
It could horizontal, vertical and diagonal.
A - vertical line of symmetry
B - horizontal line of symmetry
C - horizontal line of symmetry
D - horizontal line of symmetry
And it is an example of Spherical symmetry:
If the organism is cut through its centre, the resulting parts look the same.
Answer:
D = rate x time
D = (rate of current + rate of boat) x time
168 = (y - x) t against the current trip upstreams
168 = (y + x) t with the current trip downstream
168 = (y - x) 4
168 = (y + x) 3.5
since 168 = 168, we can set the equations equal to each other:
(y - x)4 = (y+x)3.5
4y - 4x = 3.5y +3.5x
4y - 3.5y = 3.5x + 4x
0.5y = 7.5x
y =15x
the rate of the current is 15 times the rate of the boat.
168 =4(15x) - 4x
168 = 60x - 4x
168 = 56x
x = 3
y = 15x
y = 15(3)
y = 45
