Y = 4
3x + 4x = 43
3(9) + 4x = 43
27 + 4x = 43
4x = 43-27
4x = 16
16/4 = x
4=x
x=4
Answer:
If I'm not mistaken I believe the answer is B.
Step-by-step explanation:
His total was 12 but then you have to subtract 3 for the admission fee which leaves with $9.
The inequality from option B states that the $3 from the admission and the $0.25 per game would be less than or equal to his total amount of 12.
Answer:
Step-by-step explanation:
Parallel lines are lines that never meet, from the question in the attachment above, the two lines that cannot meet are lines 'a' and 'b' and lines 'c' and 'd'
4. Question four is then lines b and a which is option B
Perpendicular lines are lines in which the angle between them is right angle (90 degrees). Which are 'a' and 'c', 'a' and 'd', 'b' and 'c', 'b' and 'd'
5. Question 5 is therefore 'a' and 'c' which is option D

Answer:
C. The square root of a number, positive or negative, is always positive. However, the cube of a negative number is negative.
Step-by-step explanation:
Of the choices offered, the one shown above is the only one that remotely makes any sense. Its description of square roots is erroneous, however.
The square root of a number n is the solution to the equation ...
x² = n
The function f(x) = x² has a range that only includes non-negative numbers, so the square root of a negative number does not exist. (Your answer choice says it is positive. It is actually non-existent among real numbers.)
On the other hand, the cube root of a number n is the solution to the equation ...
x³ = n
Since f(x) = x³ has a range that includes all real numbers, the cube root of n exists for all real numbers. (It is negative for negative values of n.)

<em>Comment on answer wording</em>
The answer wording would be correct if the word "root" were left out.
