The y-coordinate of point A is -22
Step-by-step explanation:
Given
B = (24,16)
P = (4,-3)
The formula for mid-point of AB will be given by:
As we already know the y-coordinate of midpoint
We can put the formula's y coordinate equal to the given value
Hence,
The y-coordinate of point A is -22

If the equation is -3x^2+6x-4 then the vertex is (1,-1)
Hello :
<span>the parabola's equation is : f(x) = a(x+3)²-1
</span><span>the coefficient of the squared expression in the parabola's equation is : a
but ; f(4) = 0
0 = a(4+3)²-1
49a-1=0.....a=1/49
f(x) = 1/49(x-3)²-2</span>
10 cars are silver, 20% of 50 is 10
(1) k = a + b
(2) a + b + k = 30
subtitute a + b = k to (2)
k + k = 30
2k = 30 |divide both sides by 2
k = 15
