Answer:
15
Step-by-step explanation:
because you have to add -12 with 27 and you get 15
Answer:
1,0
Explanation:
Graphically, where the line crosses the x -axis, is called a zero, or root. Algebraically, a zero is an x value at which the function of x is equal to 0 . Linear functions can have none, one, or infinitely many zeros.
The statement that describes all of the values for which the graph is positive and decreasing is:
C.) ALL REAL VALUES OF X WHERE 1 < X < 3
The number 1 ensures that the value of x will remain positive.
Since x is less than 3, then the value of x is decreasing.
Answer:
x = 7
Step-by-step explanation:
A triangle's total interior angle measurement will equal 180°.
Set all measurements equal to 180:
(82) + (9x - 6) + (6x - 1) = 180
Simplify. Combine like terms:
(82 - 6 - 1) + (9x + 6x) = 180
(82 - 7) + (15x) = 180
(75) + 15x = 180
Next, isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction

First, Subtract 75 from both sides of the equation:
15x + 75 = 180
15x + 75 (-75) = 180 (-75)
15x = 180 - 75
15x = 105
Next, divide 15 from both sides of the equation:
(15x)/15 = (105)/15
x = 105/15
x = 7
7 is your value for x.

H is the correct choice.
The diagram means that parallelograms come in two kinds: rectangles and rhombuses.
So,
.. all rhombuses are parallelograms
.. all rectangles are parallelograms
.. no rectangles are rhombuses
This diagram only recognizes parallelograms that are rectangles and rhombuses. There are also other kinds of parallelograms, but those are not shown here.
