20% if it will determine the pay of how much it is.
They are easy to compare if they all have the same common denominator, then you can easily order them by the magnitude of the numerators...
85/10, -67/10, -56/10, 82/10 so now they are easy to compare...so
-6.7, -28/5, 8.2, 17/2
Answer:
Step-by-step explanation:-16x^2 + 24x + 16 = 0.
A. Divide by 8:
-2x^2 + 3x + 2 = 0, A*C = -2*2 = -4 = -1 * 4. Sum = -1 + 4 = 3 = B, -2x^2 + (-x+4x) + 2 = 0,
(-2x^2-x) + (4x+2) = 0,
-x(2x+1) + 2(2x+1) = 0,
(2x+1)(-x+2) = 0, 2x+1 = 0, X = -1/2. -x+2 = 0, X = 2.
X-intercepts: (-1/2,0), (2,0).
B. Since the coefficient of x^2 is negative, the parabola opens downward. Therefore, the vertex is a maximum.
Locate the vertex: h = Xv = -B/2A = -24/-32 = 3/4, Plug 3/4 into the given Eq to find k(Yv). K = -16(3/4)^2 + 16(3/4) + 16 = 19. V(h,k) = V(3/4,19).
C. Choose 3 points above and below the vertex for graphing. Include the points calculated in part A which shows where the graph crosses the x-axis.
Answer:-1
Step-by-step explanation:
I rewrote it so it looks like this:
6y+6(1+3y)=-18
6y+6(1)+6(3y)=-18
6y+6+18y=-18
24y+6=-18
<u> -6 -6</u>
<u>24y</u>=<u>-24</u>
24 24
y=-1
Answer:
Scalene triangle
Step-by-step explanation:
In this question, we are asked to determine what type of triangle will be formed given the length of the pieces which was used to form the triangle.
A triangle is one of the simplest shape in geometry. In fact it is one of the basic shapes that we have in geometry. It is a 3 sided polygon that contains 3 different edges or tips and 3 vertices.
According to the values in the question, we can see that the lengths of the pieces given are different. Now what does this mean for the triangle formed?
The type of triangle formed here would be a scalene triangle. A scalene triangle is a type of triangle in which all of its 3 sides have different lengths. Consequentially, the angles formed by these three sides also are different.
