x=-2
Answer:
e = 10
Step-by-step explanation:
9e+4=-5e+14+13e
Combine like terms
9e+4=14+8e
Subtract 8e from both sides
9e-8e+4=8e-8e +14
e +4 = 14
Subtract 4 from each side
e+4-4 = 14-4
e = 10
Step-by-step explanation:
A)
Janet's took 34.56 seconds to cover 50m freestyle swim.
In words it could be said as: thirty four and fifty six hundredths.
B)
Race # Time (in sec.) time( after roundoff to nearest integer)
<em> 1 34.56 35</em>
<em> 2 35 35</em>
<em> 3 34.8 35</em>
4 34.137 34
5 33.92 34
Hence, the first 3 race times were equal after rounding off to nearest integer.
C)
on arranging the time of Janet's from fastest to slowest we get the table as:
Race # Time( in sec.)
5 33.92
4 34.137
1 34.56
3 34.8
2 35
since, after decimal we arrange the numbers in order same as we do for the natural numbers.
as in race #5 '33' is the smallest among all hence we keep it in first place.
for race 4,1 and 3 we have the same digit before decimals so now we have to look for the number after decimals.
D)
Janet's time in race #4 was: 34.137 sec.
But Grace was 1.8 seconds faster than Janet.
Hence, Grace time=34.137-1.8=32.337 sec.

Explanation:</h2>
Here we have the following points:
<h3>3) </h3>
Here we need to reflect each point over the x-axis and write the coordinates of the new points. So:
<h3>4)</h3>
The x coordinate of each point remains the same while the y coordinate of each point is multiplied by -1. In other words, when reflecting any point over the x-axis we follow this rule:
<h3>5)</h3>
The difference is that the pre-image and the reflected point will have the same x-coordinates but different y-coordinates. So the x-axis will work as a mirror.
