Answer:
x= 7
x=6
Step-by-step explanation:
5+2x=19
Subtract 5 from both sides
so...
2x=14
then divide by two to isolate the x
so..
x=7
4x+3=27
Subtract 3 from both sides
so...
4x=24
then divide by 4 to isolate the x
so....
x=6
Answer:
reflection over x axis then horizontal stretch by factor of 8/5
Step-by-step explanation:
f(x)=x
h(x) = -f(x) ... reflection over x axis (x,y) -> (x,-y)
-f(x) -> g(x) = (-5/8x) ...0 < |5/8| <1 ... horizontal stretch (x,-y) -> (x / (5/8) , -y)
One way to test this is by using the equation for Ken on Maureen. Let's say in the first hour,
f(t) = 200(0.976)^1 = 195.2 mg
In the second hour,
f(t) = 200(0.976)^2 = 190.52 mg
In the third hour,
f(t) = 200(0.976)^3 = 186 mg
If you compare this with Maureen's data which is 150, 90 and 54 for the first, second and third hour, respectively, you will see that Maureen's rate is much faster. However, you cannot tell by what factor because the function is exponential, not a multiple. There is no constant difference between their rates. Therefore, we only know that Maureen's rate is much faster.
The answer is <span>Maureen's body eliminated the antibiotic faster than Ken's body.</span>
U/72 = 2/4
means u/72 = 0.5
therefore u = 72*0.5
which equals 36
