Step-by-step explanation:
68249 divide by 10 then multiply by 3
The discriminant of a quadratic equation is a parameter that is used to determine the nature of the roots of the equation. The discriminant can be determined by b2- 4ac. The standard form of quadratic equation is ax2 + bx + c = 0. Upon substitution, we can easily determine the discriminant. If disc. is zero, the roots are equal; if <0, then the roots are positive and non-identical; if <0, the roots are negative and imaginary.
Answer:
36UNITS
Step-by-step explanation:
If point V lies between U and W, then UV+VW = UW
given parameters
UV = 2x-4
VW = 4x+10
UW = 9x-9
Substituting the given functions in the formula first, we will have;
2x-4+4x+10 = 9x-9
6x+6 = 9x-9
Collect like terms
6x-9x = -9-6
-3x = -15
x = -15/-3
x = 5
Substitute x = 5 into UW.
Since UW = 9x-9
UW = 9(5)-9
UW = 45-9
UW = 36
Answer:
25
Step-by-step explanation:
All rhombuses have all 4 sides equal, so then AD = AB = 25.
We are required to find the cost of each cherry tree and rose bushes.
The cost of each cherry tree, x is $8 and the cost of each rose bushes, y is $12
let
<em>cost of each cherry tree = x</em>
<em>cost of each cherry tree = xcost of each rose bushes = y</em>
The equation:
7x + 11y = 188 (1)
13x + 11y = 236 (2)
Subtract (1) from (2) to eliminate y
13x - 7x = 236 - 188
6x = 48
divide both sides by 6
x = 48 / 6
x = 8
substitute x = 8 into (1)
7x + 11y = 188 (1)
7(8) + 11y = 188
56 + 11y = 188
11y = 188 - 56
11y = 132
divide both sides by 11
y = 132 / 11
y = 12
Therefore, the cost of each cherry tree, x is $8 and the cost of each rose bushes, y is $12
