Answer:
sorry this took 30mins
Step-by-step explanation:
1+1-1=1
I would go with Never because you would have to have two circles with a different center to be congruent
We can find the answer by solving the two equations simultaneously.
equation 1: y = -0.4x^2 +3xequation 2: x + y = 10
We need to write equation to with y as the subject:equation 2: y = 10 - x
equation 1 = equation 2:
10 - x = -0.4x^2 + 3x0.4x^2 - 4x + 10 = 02x^2 - 20 + 50 = 0(2x - 10)(x - 5) = 0x = -10/2 or x = 5
But x >= 0 (the question says it's a height above the water), so x = 5
Substituting x = 5 into one of the equations:
y = 10 - x
y = 10 - 5
y = 5
So the answer is C
Answer:
what u r answering but ya
Step-by-step explanation:
Answer:
Solution given:
9x-2y=7
making it in a form of y=mx+c
9x-7=2y
y=9/2x -7/2
Comparing above equation with y=mx+c
we get
m=9/2
Since it is passes parallel to (5,-3)
slope will be same
now
Equation of line
y-y1=m(x-x1)
y+3=9/2(x-5)
y=9/2x-5/2-3
<u>y=9/2 x-11/2 is a required equation.</u>
