On the x axis means that the y value is 0 or the point is (x,0)
distance formula
D=
we know that distance is 5
the first point is (x1,y1)
the (x2,y2) is (x,0)
so
D=5
x1=-8
y1=3
x2=x
y2=0
5=
5=
5=
5=
square both sides
25=
minus 25 both sides
0=x^2+16x+48
factor
0=(x+4)(x+12)
set each to zero
x+4=0
x=-4
x+12=0
x=-12
the points are
(-4,0) and (-12,0)
Answer:
B has a smaller initial population of 500
Step-by-step explanation:
Given
See attachment for complete question
Required
The bacteria with the smaller initial population
The initial population is at x = 0
For bacteria A;
when
For bacteria B, we have:
Substitute 0 for x
So; when x = 0
and
Because; 500 < 600
We can conclude that B has a smaller initial population of 500
4x+1-5x=5-(x+4)
Do the parenthesis first which’s
4x+1-5x=-5x-20
Now we have to combine the like terms
Which’s -x+1=-5x-20
Now we have to put the x together
-x+1=-5x-20
-x. -x
1=4x-20
Also we need to put the x by itself so we will add 20 to both sides
1=4x-20
+20 +20
Which is 21=4x
Now we have to divide the both sides by 4 to get the x by itself
21/4=4x/4
So the answer will be 21/4=x
Convert to base 12:
1 9/12+4 7/12
Then, add!:
5 16/12=6 4/12 =6 1/3
The answer is 6 1/3.
