Answer:
8 and 8 because the mode means the most numbers that are the same and the median is the middle number in the sequence
Step-by-step explanation:
<u>1. For what numbers the function is null ?</u>, so there is one solution :
<u>2. For what numbers the function is negative ?</u>The function is a parabola<span> </span> <span>upturned (
)</span>, so if its don't cut the abscissa line (0 to 1 solution where the function is null), there is no negative numbers.
Here, there is just one solution who cut the abscissa line, so there is no solution for the negative function.
<span>
The function is never negative</span>.
The solutions to the given equations are
m = - 30/7
v = 8.8
x = -3
u = 4
a = -3/70
<h3>Solving linear equations</h3>
From the question, we are to determine the values of the variables in the equations
7/8m - 4/7 - 5/6m = -3/4
7/8m - 5/6m = -3/4 + 4/7
(21m -20m)/24 = (-21 + 16)/28
m/24 = -5/28
m = (-5×24)/28
m = -120/28
m = - 30/7
4.3v + 10.75 - 4v = 8.11
4.3v - 4v = 8.11 - 10.75
0.3v = -2.64
v = -2.64/0.3
v = 8.8
9/7 + 9/7x - 6/7x = 0
9/7x - 6/7x = -9/7
(9x - 6x)/7 = -9/7
3x/7 = -9/7
3x × 7 = -9 × 7
21x = -63
x = -63/21
x = -3
6.9u - 2 - 3.2u - 10 = 2.8
6.9u - 3.2u = 2.8 + 2 + 10
3.7u = 14.8
u = 14.8/3.7
u = 4
8/5 = -4a + 7/5 - 2/3a
8/5 - 7/5 = -4a - 2/3a
(8-7)/5 = -14/3 a
1/5 = -14/3 a
-14a × 5 = 1 × 3
-70a = 3
a = 3 / -70
a = -3/70
Hence, the solutions to the given equations are
m = - 30/7
v = 8.8
x = -3
u = 4
a = -3/70
