Answer:
In algebra, quadratic functions are any form of the equation y = ax2 + bx + c, where a is not equal to 0, which can be used to solve complex math equations that attempt to evaluate missing factors in the equation by plotting them on a u-shaped figure called a parabola. The graphs of quadratic functions are parabolas; they tend to look like a smile or a frown.

Roll the die 30 times, recording the result each time. Afterwards count the number of times you rolled 1-4 and the number of times you rolled 5-6; use these to find the experimental probabilities.
The answer is A. Y=2x+2
Because the slope is 2 and it crosses the Y axis at 2
Answer:
Step-by-step explanation:
Here it is given that , a postal service charges a flat rate of 11.10 and a additional rate of 3 / kg .We need to write the equation in slope intercept form . And let ,
So the total cost would be the sum of flat rate plus the cost of the total weight . Therefore,
Therefore the total cost would be,
Rearrange in slope intercept form , which is y = mx + c , as ;
