Answer: A. -17 , 19
Step-by-step explanation:
Move all terms to one side.
z^2-2z-323=0
z^2 −2z−323=0
Factor : z^2-2z-323
z^2−2z−323.
(z-19)(z+17)=0(z−19)(z+17)=0
Solve for z.
z=19,−17
Answer:
Yes the y value an have more than one x value BUT the x value can only have one y value.
Step-by-step explanation:
example if we have 1 and it goes to 2 the 1 cant go to another number such as 3.. if we had another number like 4 and it goes to 2 like the 1 it would be acceptable
hope this helped and is not to confusing-
Answer:
the vertex is a, (3,-16). The x intercepts are D, (-1,0) and (7,0)
step-by-step explanation:
you graph it.
The general equation use to calculate increasing or decreasing values
P(t) = A(1 + r)^t
where:
P = New value
A = original or starting amount
r = rate (can be either increasing(+) or decreasing(-))
t = time period that increase/decrease take place.
So after 1 year at 3.8% interest
P = 7500(1 + 0.038)^1
P = 7500(1.038)
P = 7,785
Then after 1 year at 5.35 interest
P = 7500(1 + 0.053)^1
P = 7500(1.054)
P = 7,897.50
Answer:
The number of bacteria in 0.25 mL is 6.25 x 10^3.
Step-by-step explanation:
5 liter flask contains 1.25 x 10^8 bacteria.
