Answer:
(c) -3.8, 3
Step-by-step explanation:
The solutions to the equation f(x) = g(x) are the values of x where the function values are equal. These are the x-coordinates of the points where the graphs of y=f(x) and y=g(x) intersect each other.
<h3>Points of intersection</h3>
The points where the graphs cross can be estimated to be ...
(-3.8, 6.5) and (3, -6)
The x-coordinates of these points are the solutions to the equation:
x = -3.8, 3
Step-by-step explanation:
formula of trapezoid's area =1/2(a+b)(height)
a/b= upper or below part of trapezoid
area of trapezoid=1/2 (4+7)(5)
=1/2 (11)(5)
=27.5cm²
Answer:
5
Step-by-step explanation:
5 of them play neither sport.
We can subtract 5 from 21 to get the kids that play a sport.
16-(14+6), is -4.
so 4 is the number of kids that play both sports.
so the probability is 4/21.
Explanation:
The formula isnt correctly written, it should state:
You have to start from and end in a³+b³. On your first step, you need to use the distributive property.
This is equal to
Note that the second term, -a²b, is cancelled by the fourth term, ba², and the third term, ab², is cancelled by the fifht term, -b²a. Therefore, the final result is a³+b³, as we wanted to.
