Answer:
C. x ≈ 0.28
Step-by-step explanation:
A graphing calculator solution is attached. It shows ...
x ≈ 0.28
__
You can divide both sides of the given equation by 5, then take natural logs and divide by 5 again.
5e^(5x) = 20 . . . . . . given
e^(5x) = 4 . . . . . . . . divide by 5
5x = ln(4) . . . . . . . . take natural logs
x = ln(4)/5 . . . . . . . divide by 5
x ≈ 0.277259 ≈ 0.28
Answer:
Angle EDF= 53
Step-by-step explanation:
Supplementary angle: Angle EDC and angle EDF
which means angle EDC+ Angle EDF=180
Angle EDC show in the graph 127 degree
Angle EDG= 180-127=53Degree
Answer: 9/10
Explanation:
3/4 divide by 5/6
= 3/4 x 6/5
= 18/20
= 9/10
C=2 and j=4
j+y=2(c+y)-7
j+y=2c+2y-7 and since j=4 and c=2 we have:
4+y=2*2+2y-7
y+4=2y+4-7
y+4=2y-3
-y+4=-3
-y=-7
y=7
So in 7 years Jenny will be 7 years younger than twice Chris' age.
check...
4+7=2(2+7)-7
11=2(9)-7
11=18-7
11=11
