Answer:
A. 4x² - 2x + 11
Step-by-step explanation:
(4x² + 6) - (2x - 5) =
Drop the first set of parentheses since it is unnecessary.
= 4x² + 6 - (2x - 5)
To drop the second set of parentheses, you must change every sign inside the parentheses.
= 4x² + 6 - 2x + 5
Now combine like terms.
= 4x² - 2x + 11
Answer:
x=-7
Step-by-step explanation:
5(-2x-3)-4x-5=78
-10x-15-4x-5=78
-14x-20=78
<u> +20 +20</u>
<u>-14x</u>=<u>98</u>
-14 -14
x=-7
Answer:
28 baskets
Step-by-step explanation:
The equation for a linear trend line is given by:
y = mx + b, where y and x are variables, m is the slope of the line and b is the y intercept (that is value of y when x is zero).
The equation of a line passing through two points is:
y represent the number of baskets made and x represents the time take. Given that the line passes through the points (0, 11) and (100, 33), hence:
The number of baskets Romy would make after practicing for 80 minutes (x = 80) is:
Answer:
6n -37
Step-by-step explanation:
The slope would be the derivative of the function
dy/dx = 6x - 37 evaluated at the point n
dy/dx = 6n -37
