Answer:
-5
Step-by-step explanation:
multiply both sides of the equation by the denominator(12)
thus giving:
14+10x=-3(12)
14+10x=-36
take 14 to the other side;
10x=-36-14
10x=-50
divide both side by 10
x=-5
We can do anything to an equation as long as we do it to both sides
given:
square both sides
minus 3 from both sides
multiply both sides by 6
minus 4
square both sides
do for -4+6 and -4-6 (2 and -10)
and
minus 3

x=97 doesn't work
the answer is x=1
The range of the function is {-7, -1, 0, 9}.
These are all of the y values in the ordered pairs, which is the definition of what range is.
Answer:
The expression in simplified radical form is:
√ 25 –2√3 + √27 +2√ 9 = 11 + √3
Step-by-step explanation:
Given the expression
√ 25 –2√3 + √27 +2√ 9
as
√ 25 = 5
√27 = 3√3
2√9 = 6
so the expression becomes
√ 25 –2√3 + √27 +2√ 9
= 5 - 2√3 + 3√3 + 6
= 11 + √3
Thus, the expression in simplified radical form is:
√ 25 –2√3 + √27 +2√ 9 = 11 + √3
Answer:
Option D
Step-by-step explanation:
<u><em>The measure of the exterior angle is equal to the sum og non-adjacent interior angle</em></u>
=> 105 = 55 + x
<em>Subtracting 55 to both sides </em>
=> x = 105-55
=> x = 50 degrees
