Given:
CDEF is a rhombus.
To find:
The value of x.
Solution:
We know that the diagonals of a rhombus are angle bisectors because they bisect each vertex angle.
Divide both sides by -3.
Therefore, the value of x is 7.
Answer:
<h2>2.5*10^0</h2>
Step-by-step explanation:
To write a number in scientific notation or standard form we write the number and multiply it by 10 to the power of any number
The proper format for scientific notation is a x 10^b and it is read "a times 10 to the power of b"
Given the diameter of 2.5
in standard form or scientific notation is

Answer:
Zero's
Step-by-step explanation:
Answer:
a) one solution
b) no solution
Step-by-step explanation:
Systems of equations can be described as having one solution, no solution or infinite solutions:
One solution: 'x' and 'y' are equal to only one value
No solution: 'x' and 'y' can not be solved with the given equations
Infinite solutions: values for 'x' and 'y' include all real numbers
In order to evaluate the systems, putting them in the same format is your first step:
a) - y = -5x - 6 or y - 5x = 6
y - 5x = -6
Since both equations have the same expression 'y - 5x', but there are equal to opposite values, this system would have no solution, as this would not be possible to calculate.
b) y + 3x = -1
y = 3x -1 or y - 3x = -1
Solving for 'y' by adding the equations and eliminating 'x', gives us:
2y = -2 or y = -1
Using y = -1 to plug back into an equation and solve for 'x': -1 + 3x = -1 or x = 0. Since 'x' and 'y' can be solved for a value, the system has just one solution.
