What are the x-intercepts of f(x) = x(x + 1)(x - 4)(x+8)??
Answer:
f(x)= 3x^2+5x
Step-by-step explanation:
f(x)= x(x+1)(x-4)(x+8)
f(x) = x^2 + x + x^2 - 4x + x^2 + 8x
f(x) 3x^2 + 5x

Jacob decided to start saving for college. After 3 months, he had saved $174. His friend Victoria was inspired to do the same. After 6 months, she had saved $360. If they are both saving money at a constant rate, how many more dollars per month does Victoria save than Jacob?
Answer:
$2 more.
Step-by-step explanation:
In this question, we have to find how much more money Victoria is saving.
We know that Jacob saved $174 in 3 months.
We also know that Victoria saved $360 in 6 months.
Lets find how much money they save per month:
Jacob:
174 ÷ 3 = 58
Victoria:
360 ÷ 6 = 60
Jacob is saving $58 per month and Victoria is saving $60 per month.
This means that Victoria is saving $2 more than Jacob per month.

9514 1404 393
Answer:
10
Step-by-step explanation:
Let L and T represent the initial amounts that Leo and Theo had. Let n represent the number of bills exchanged in the first exchange. Then we have ...
L -20n +50n = T -50n +20n . . . . after the first exchange, each has the same
After the second exchange, amounts trade places:
(L +30n) +6(50) = T
Substituting this into the first equation, we get ...
L +30n = ((L +30n) +300) -30n
30n = 300
n = 10
Leo gave Theo ten $20 bills.
_____
Comment on the amounts
Theo started with $600 more than Leo, including exactly 16 $50 bills. Leo had at least 10 $20 bills, so he could make the initial exchange. Whatever initial amount Leo had in excess of that $200 was matched in Theo's initial amount, but Theo must have had that excess in $20 bills only. For example, Leo may have started with $300 as 10×$20 +2×$50, but Theo's initial $900 would need to be 5×$20 +16×$50.
What is the value of the expression 9 + ( fraction 1 over 2 )4 ⋅ 48?
Answer:
105
Step-by-step explanation:
9 + (1/2)4 x 48
9 + 96 = 105
Answer:
105
Step-by-step explanation:
SO, based on the way you worded it, the equation is
[tex]9 + 1/2 *4*48[/tex]
You multiply [tex]1/2 * 4[/tex] first.
This gives you 2. [tex]2*48=96[/tex]
96 + 9 =105
For questions 1 – 6, find the area of the circle to the nearest hundredth.
Any help appriciated!
Step-by-step explanation:
The area of a circle is given by :
A = πr²
r is the radius of the circle
(4) Diameter = 22 cm
Since, radius = diameter/2
r = 11 cm
Now, area of the circle,
[tex]A=\pi \times (11)^2\\\\A=380.13\ cm^2[/tex]
(5) Diameter = 30 cm
Since, radius = diameter/2
r = 15 cm
Now, area of the circle,
[tex]A=\pi \times (15)^2\\\\A=706.85\ cm^2[/tex]
(6) Diameter = 4cm
Since, radius = diameter/2
r = 2 cm
Now, area of the circle,
[tex]A=\pi \times (2)^2\\\\A=12.56\ cm^2[/tex]
So, the area of circles 4,5 and 6 are 380.13², 706.85² and 12.56² respectively.
If f(x) = 3x - 1 and g(x) = x + 2, find (f- g)(x).
I can’t find it
Answer:
[tex](f-g)(x)=2x-3[/tex]
Step-by-step explanation:
We are given the two functions:
[tex]f(x)=3x-1\text{ and } g(x)=x+2[/tex]
And we want to find:
[tex](f-g)(x)[/tex]
This is equivalent to:
[tex]=f(x)-g(x)[/tex]
By substitution:
[tex]=(3x-1)-(x+2)[/tex]
Simplify. Distribute:
[tex]=(3x-1)+(-x-2)[/tex]
Rearrange:
[tex]=(3x-x)+(-1-2)[/tex]
Therefore:
[tex](f-g)(x)=2x-3[/tex]

jun uses a 20%-off coupon to by the ingredents for congee. she spends $40. what is the regular price r of the ingredeints before the discount
Answer:
$50
Step-by-step explanation:
Make the equation where x is the original price:
x - 0.2x = 40
Combine like terms
0.8x = 40
Divide both sides by 0.8
40/0.8 = 50
Solve for x,
45=3x

Suppose you are testing two fertilizers on bamboo plants A and B, which are growing under identical conditions. Plant A is 6 cm tall and growing at a rate of 4 cm per day. Plant B is 10 cm tall and growing at a rate of 2 cm per day.
Answer:
2 days
Step-by-step explanation:
Step one:
let the number of days be x
and the total height be y
Plant A is 6 cm tall and growing at a rate of 4 cm per day.
the total height is
y=6+4x------------1
Plant B is 10 cm tall and growing at a rate of 2 cm per day.
y=10+2x-----------2
Required
time taken for both plants to have the same height
Step two:
equate the two equations to find when the plants will have the same height
6+4x=10+2x
collect like terms
4x-2x=10-6
2x= 4
divide both sides by 2
x= 4/2
x= 2 days

2. The new Ferrari can accelerate from rest to 100 km/hr in 5 seconds. What is the average acceleration of the car in m/s2?
3. A car starts from a stoplight and is traveling with a velocity of 10 m/sec east in 20 seconds. What is the acceleration of the car?
4. A ball is rolled at a velocity of 12 m/s. After 36 seconds, it comes to a stop. What is the acceleration of the ball?
Answer:
The answer is below
Step-by-step explanation:
Acceleration is the time rate of change in velocity. Acceleration is given by:
Acceleration = change in velocity / time taken
Acceleration = (final velocity - initial velocity) / time
1) The Ferrari is from rest, hence initial velocity = 0. The final velocity = 100 km/h = [tex]\frac{100\ km*1000\ \frac{m}{km} }{1\ hr*\frac{3600\ s}{1\ hr} } =27.78\ m/s[/tex], time = 5 s
Acceleration = (0 - 27.78) / 5 = 5.56 m/s²
2) The car has initial velocity = 10 m/s. The final velocity = 10 m/s since velocity is constant. time = 20 s
Acceleration = (10 - 10) / 20 = 0 m/s²
3) The ball has initial velocity = 12 m/s. The final velocity = 0 m/s since it stops. time = 36 s
Acceleration = (0 - 12) / 36 = -0.33 m/s²
Solve 3x − 5y = 17
9x − 15y = −4
Answer:
3x - 5y = 17
3(9) - 5(2) = 17
27 - 10 = 17
x = 9
y = 2
---------------------
9x - 15y = -4
I believe this equation has no proper solution. Every "solution" I have found ends with repeating decimals & fractions.
