Answer:
One-fifth
Step-by-step explanation:
step 1
Find the distance between the origin and the point B
the formula to calculate the distance between two points is equal to
we have
O (0,0) and B(10, –15)
substitute
step 2
Find the distance between the origin and the point B'
the formula to calculate the distance between two points is equal to
we have
O (0,0) and B'(2,-3)
substitute
step 3
Find the scale factor of the dilation
The scale factor is equal to divide the length of segment OB' by the length of segment OB
so
so
One-fifth
Answer:
3
Step-by-step explanation:
First we pick the equation. Let's say we pick first one. From it we express y.
Then we use this y and plug it in instead of y in the second equation.
Now just solve for x.
We plug this x in the first equation.
And solve for y.
So the solution to the equation is geometrically a point P which lies on the intersection of the two lines.
Hope this helps.

Answer:
The equation for difference in altitude of the two helicopters is A = 650 - 100t
Step-by-step explanation:
Given;
The altitude of one helicopter is, A1 = 600 + 150t
The altitude of a second helicopter is, A2 = 1250 + 50t
Their difference in altitude, A at time t, is calculated as
A₂ - A₁ = A = (1250 + 50t) - (600 + 150t)
A₂ - A₁ = A = 1250 + 50t - 600 -150t
A₂ - A₁ = A = 1250 - 600 + 50t - 150t
A₂ - A₁ = A = 650 - 100t
Therefore, the equation for difference in altitude of the two helicopters is A = 650 - 100t
