Answer:
greater than or equal to 120
Step-by-step explanation:
4+11=15
x is over 15
8*15=120
therefore x must be greater than or equal to 120
Answer:
C
Step-by-step explanation:
Given
2x² + x - 1 = 2 ( subtract 2 from both sides )
2x² + x - 3 = 0
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 2 × - 3 = - 6 and sum = + 1
The factors are - 2 and + 3
Use these factors to split the x- term
2x² - 2x + 3x - 3 = 0 ( factor the first/second and third/fourth terms )
2x(x - 1) + 3(x - 1) = 0 ← factor out (x - 1) from each term
(x - 1)(2x + 3) = 0
Equate each factor to zero and solve for x
x - 1 = 0 ⇒ x = 1
2x + 3 = 0 ⇒ 2x = - 3 ⇒ x = - 
The equation which represents the data in the table as in the task content is; Choice C; y = 2x +3.
<h3>What is the equation which represents the data in the table as attached?</h3>
It follows from the task content that the slope of the relation can be determined by means of the slope formula for a linear equation as follows;
Slope = (1-(-1))/(-1 -(-2))
Slope = 2.
Hence, the equation which represents the function is;
2 = (y-(-1))/(x -(-2))
2x + 4 = y +1
y = 2x + 3.
Therefore, the equation which represents the data in the table as in the task content is; Choice C; y = 2x +3.

Add the two speeds together, then divide the two, this gives the average speed. Hope this was helpful!
