Answer:
2x² + 9x - 5
Step-by-step explanation:
Given
(2x - 1)(x + 5)
Each term in the second factor is multiplied by each term in the first factor, that is
2x(x + 5) - 1(x + 5) ← distribute both parenthesis
= 2x² + 10x - x - 5 ← collect like terms
= 2x² + 9x - 5
Answer:
it should be x=4
Step-by-step explanation:
The line that is perpendicular to
y
=
−
3
is a horizontal line, because horizontal and vertical lines (
x
- and
y
- axes for example) are perpendicular. Therefore, this line will take the form
x
=
n
where
n
is the
x
-coordinate of the point passed through. The
x
-coordinate of the given ordered pair
(
4
,
−
6
)
is
4
, so the equation must be
x
=
4
The answer is Right angles
Answer:
B. The experiment is rolling the die.
C. A trial is one rolling of the die.
F. The outcome is the number that is rolled on the die.
Step-by-step explanation:
An experiment is defined as an act or operation for the purpose of discovering something unknown. In this case the player is rolling the die to discover a number, thus the experiment is rolling the die.
A trial is a single performance of a defined experiment, since we already know what the experiment is, a trial is one rolling of the die.
The outcome is the observed result from a trial or experiment, in this case, the outcome is the number that is rolled on the die.
