The problem gives you X, so replace X witht he given vaule and solve for y:
y = -0.1x^2 + 4X
X = 40
y = -0.1(40)^2 +4(40)
y = -0.1(1600) + 160
y = -160 + 160
y = 0
The equation of a circle is (x - a)² + (y - b)² = r², where the coordinates of the center(C) are C(a,b) and "r" the radius. Here, C(12, 32) and r=7 if you need, so there is no correct alternative.
This equation would have no solutions.
This is because if we expand the brackets we get:
6(x - 1) = 2(3x - 2)
6x - 6 = 6x - 4
And it is not possible for this to be true because it states that subtracting 6 from a number gives the same result as subtracting 4 from that number, which is not true. Therefore there are no .
I hope this helps!
3x2+9x-54
6+9x-54
6-54+9x
-48+9x
Answer:
Test the two ratios/fractions to see whether they are equivalent by multiplying diagonally (cross multiply). 3 4 = 15 20 4 * 15 = 60 and 3 * 20 = 60.
<em><u>This is a proportion. If the two numbers that are diagonal result in the same answer when they are multiplied, you are working with a proportion.</u></em>
