Answer:
Answers are below
Step-by-step explanation:
The axis of symmetry for f(x) is at x = 4 because it splits the function in half. I found it by looking at the vertex of the parabola and using the x-value as the axis of symmetry.
The axis of symmetry for h(x) is at x = -2 because it splits the function in half. I found it by looking at the vertex of the parabola and using the x-value as the axis of symmetry.

Answer:
y= -23x+142
Step-by-step explanation:
we know that our equation has to look likethis
y=mx+b
where m is the slope and b is the y intercept
we're given that m = -23 so we have
y= -23x+b
we also know that when x=6 y=4 so we can just plug those values in and solve for b
4= -23(6)+b
142=b
Which means our equation is
y= -23x+142
We are given that the cost of each shirt = $12.25
It is given that she bought total 'x' shirts, each of cost $12,25.
So, the cost of 'x' shirts is dollars
Also, there is a shipping charge of $3.99
So, the total cost of 'x' shirts is
Since, the shirts cost her total $77.49.
We have the equation,
12.25x + 3.99 = 77.49
Answer:
Step-by-step explanation:
<u>Given:</u>
- Initial amount of bacteria = 50000
- Growth rate = 2 times a day
<u>Required equation:</u>
<u>Solve for x:</u>
- 400000 = 50000*2^x
- 2^x = 400000/50000
- 2^x = 8
- 2^x = 2^3
- x = 3
After 3 days bacteria numbers will reach 400000
Answer:
z1 + z2 = 3
Step-by-step explanation:
Since we are given z1 = 2 + √(3)i and z2 = 1 – √(3)i. The sum of z1 + z2 would be:
(2 + √(3)i) + (1 – √(3)i) = 2 + √(3)i + 1 – √(3)i = 2 + 1 + √(3)i – √(3)i = 3
Hence, z1 + z2 = 3.
