Answers
Answer: y=5x+4
Step-by-step explanation:
Remember this
Slope-Intercept form: y=mx+b
m is the slope (5)
b is the y-intercept (4)
So your equation is
y=5x+4
Answer:
y = 5x + 4
Step-by-step explanation:
y - 4 = 5(x - 0)
That is point-slope form. I'm not sure if you want it in slope-intercept form, but the slope-intercept form of the equation is -
y = 5x + 4

Answers
Answer:
Negative
Step-by-step explanation:
Years of Factoring:
What the problem tells us is that we have:
X^2 - 4x - 3
or something along these lines. If we factor this we get:
(X-4)(X+1)
The bigger inside factor has to be negative for these problems, because the third term is negative.
The sum of the middle term must give a negative value.
What is a quadratic equation?A quadratic equation is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.
Given that If the middle term of a quadratic trinomial is negative and the last term is negative then the sum of the middle terms must give a negative value.

Hi! From what I know, your answer should be 5n = 1.75.
This is because all 5 of those n's ultimately equal the large box of 1.75 on the top. Think of it as fractions. if we replaced 1.75 with 1, those n's would each be 1/5.

A square pool has a volume 4,086 cubic feet and depth 9 feet. A couple builds a fence 3.5 feet high around the pool. How many square feet of fencing surround the pool?
Answers
Answer:
Are they going to build the fence on the edge of the pool? How are they going to get into the pool? This question is illogical, however....
Step-by-step explanation:
A square pool is also wierd.
Volume Pool = side × side × depth
Volume Pool / depth = side² solve for side
side² = Volume Pool / depth
the fence is 3.5 feet tall
Fencing sqft one side = side × fence height for ONE side
Total Fencing = 4 × Fencing sqft one side
side² = 3464 ft³ / 8 ft
= 422 ft²
side = √422 ft²
= 20.54 ft
Fencing area one side = 20.54 × 3.5
= 71.899 ft²
Total fencing = 4× 71.899 ft²
= 287.6 ft² to the nearest tenth <-------------------- FINAL ANSWER

The doubling period of a bacterial population is 15 minutes. At time t= 80 minutes, the bacterial population was 90000
Answers
Answer:
here i finished!
hope it helps yw!
Step-by-step explanation:
The doubling period of a bacterial population is 15 minutes.
At time t = 90 minutes, the bacterial population was 50000.
Round your answers to at least 1 decimal place.
:
We can use the formula:
A = Ao*2^(t/d); where:
A = amt after t time
Ao = initial amt (t=0)
t = time period in question
d = doubling time of substance
In our problem
d = 15 min
t = 90 min
A = 50000
What was the initial population at time t = 0
Ao * 2^(90/15) = 50000
Ao * 2^6 = 50000
We know 2^6 = 64
64(Ao) = 50000
Ao = 50000/64
Ao = 781.25 is the initial population
:
Find the size of the bacterial population after 4 hours
Change 4 hr to 240 min
A = 781.25 * 2^(240/15
A = 781.25 * 2^16
A= 781.25 * 65536
A = 51,199,218.75 after 4 hrs
