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
Find the area of the figure to the nearest hundredth.
Answer:
51.26 ft
Step-by-step explanation:
First find the area of the triangle:
a=1/2 base times height
a=(1/2)(6)(4)
a=12 ft
Now find the area of the circles:
a= pi times radius squared
a= pi times 2.5 squared
a=19.63 ft
19.63 + 12 = 31.63 ft

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.

The doubling period of a bacterial population is 15 minutes. At time t= 80 minutes, the bacterial population was 90000
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

A health insurance plan costs $150 each month plus an extra $25 for each doctor's visit. Which equation
below models the total yearly cost, c, of the plan
as a function of the number of doctor's visit, n?
Answer:
c=150+25n
Step-by-step explanation:
Given data
Monthly cost= $150
cost per doctor's visit= $25
Let the number of visits be n
Hence the total cost c can be modeled as
[tex]c=150+25n[/tex]
If the middle term of a quadratic trinomial is negative and the last term is negative, then
the sum of the factors for the middle term must be __
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.
What the problem tells us is that we have:
x² - 4x - 3
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.
Therefore, the sum of the middle term must give a negative value.

Lydia invested $5900 in an account paying an interest rate of 2 5/8% compounded monthly. Jace invested $5900 in an account paying an interest rate of 2 1/8% compounded continuously. After 19 years how much more money would lydia have in her account than jace to the nearest dollar.
Answer:
$875.18
Step-by-step explanation:
Given data
Lydia
P=$5900
Interest rate=2 5/8% >>21/8= 2.625%
compounded monthly.
First, convert R percent to r a decimal
r = R/100
r = 2.625%/100
r = 0.02625 per year,
Then, solve our equation for A
A = P(1 + r/n)^nt
A = 5,900.00(1 + 0.0021875/12)^(12)(19)
A = $ 9,710.01
Jace
P=$5900
Interest rate= 2 1/8% >>> 17/8>> 2.125%
Time= 19 years
First, convert R percent to r a decimal
r = R/100
r = 2.125%/100
r = 0.02125 per year,
Then, solve our equation for A
A = Pert
A = 5,900.00(2.71828)^(0.02125)(19)
A = $ 8,834.83
Hence the difference in their account balance is
= 9,710.01- 8,834.83
=$875.18
Therefore Lydia has $875.18 more money than Jace

The area of two similar triangles are 50dm^2 and 32dm^2. The sum of their perimeters is 117dm. What us the perimeters of each of these triangle?
Answer:
Perimeter of one triangle is 65 dm
Perimeter of other triangle is 52 dm
Step-by-step explanation:
Please remember the concept
If sides are in the ratio of a:b
Then the area in the ratio of [tex]a^{2} :b^{2}[/tex]
It is given sum of their perimeter is 117.
Let the small triangle has perimeter as x.
So, perimeter of big triangle is 117-x.
So, we can set up equation as
[tex]\frac{50}{32} =\frac{x^{2} }{(117-x)^{2} }[/tex]
Cross multiply
50(117-x)^2 =32x^2
Expand the left side
50[tex](13689 -234x+x^{2} )[/tex]=[tex]32x^{2}[/tex]
Distribute the left side
684450-11700x+[tex]50x^{2}[/tex]=[tex]32x^{2}[/tex]
Subtract both sides [tex]32x^{2}[/tex] and rewrite it [tex]18x^{2} -11700x+684450=0[/tex]
Solve this quadratic for x.
Divide both sides of the equation by 18 to simplify.
[tex]x^{2}[/tex]-650 x+38025=0
Now, if possible let's factor
Find two integers whose multiplication is 38025 but adds to -650.
-65 and -585 works.
So, we can rewrite it as
(x -65)(x-585) =0
Solve them using zero product property
x=65, x=585
So, x=65 works here.
So, perimeter of one triangle is 65 dm
Perimeter of other triangle is 117-65= 52 dm

Answer:
The game (including tax) would cost $31.80
Step-by-step explanation:
6% of 30.00 is 1.8 so sales tax would be $1.80
$30.00 + $1.80 = $31.80
Answer:
$31.8
Step-by-step explanation:
here's your solution
=> Cost of video game = $30
=> sale tax = 6%
=>now we need to calculate 6% of $30
=> 6/100*30 = $1.8
=> sale tax = $1.8
=> cost of video game including tax = $30 + $1.8
=> $31.8

At Janice's current age she is not only 5 times as old as Ross, but she is also 28 years older than Ross. How old is Janice?
Janice's age is 35 years.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Ross age = x
Now,
Janice age = 5x ____(1)
Janice age = x + 28 _____(2)
From (1) and (2),
5x = x + 28
5x - x = 28
4x = 28
x = 7
Now,
Janice age.
= 5 x 7
= 35
Thus,
Janice's age is 35 years.

b increased by 250% compared to 2b decreased by 50%
Answer:
$a decreased by 25% and $1.2a decreased by 40%
$a decreased by 25% = 0.75a
1.2a decreased by 40% = 0.6*1.2a = 0.72a
2) $b increased by 250% and $2b increased by 50%
$b increased by 250% = 2.5b
$2b increased by 50% = 1.5*2b = 3b
Answer:
b increased by 250% is equal to 2b decreased by 50%
$b increased by 250% > $2b increased by 50%
