Answer:
O x >9
The arrow points left
Step-by-step explanation:
<u><em>Explanation:-</em></u>
<em>Given 2 < x-7</em>
<em>adding '7' on both sides, we get</em>
<em>⇒ 2 + 7 < x -7 +7</em>
<em>⇒ 9 < x</em>
<em>⇒ x>9</em>
<em>Given inequality 2 < x -7</em>
The arrow points left
<u><em>Final answer</em></u>:-
solution is x >9
The arrow points left
Answer:
5.7 units
Step-by-step explanation:
The distance from point P to QS is the distance from point P (1, 1) to the point of interception R(-3, 5).
Use distance formula to calculate distance between P and R:
Let,
Plug in the values into the formula.
(to nearest tenth)
Answer:
Median: 7.5
Mean: 8.6
Step-by-step explanation:
Median = the average of the 2 middle numbers of the set in ascending order, 6, 6, 6, <u>7, 8</u>, 10, 12, 14
(7+8)/2 = 2
Mean = the sum of the numbers divided by the number of values
6 + 6+ 6+ 7 +8 +10 +12 +14/8
69/8
8.625
Solution for (-4z^2-11u)-5z^2=
<span>Simplifying
(-4z2 + -11u) + -5z2 = 0
Reorder the terms:
(-11u + -4z2) + -5z2 = 0
Remove parenthesis around (-11u + -4z2)
-11u + -4z2 + -5z2 = 0
Combine like terms: -4z2 + -5z2 = -9z2
-11u + -9z2 = 0
Solving
-11u + -9z2 = 0
Solving for variable 'u'.
Add '9z2' to each side of the equation.
-11u + -9z2 + 9z2 = 0 + 9z2
Combine like terms: -9z2 + 9z2 = 0
-11u + 0 = 0 + 9z2
-11u = 0 + 9z2
Remove the zero:
-11u = 9z2
Divide each side by '-11'.
u = -0.8181818182z2
Simplifying
u = -0.8181818182z<span>2</span></span>
