Answer: 8 1/20 or 8.05.
Step-by-step explanation: First you would want to make 9 3/4 - 2 1/5 to 39/4 - 11/5. We need to get the LCD or Least Common denominator of 4 and 5, which is 20. The rule is what you multiplied the denominator by you must multiply the numerator by, so our new equation is 195/20 - 44/20, which is 151/20. Now, we have to find the LCD of 2 and 20, which is 10. So 151/20 + 10/20 is 161/20 or 8 1/20.
What is the sequence of the n^"th" term equation f(n) = -3n +7 for n 1
Answer:
The sequence of the given equation
4 , 1, -2 , -5, ......
∴ The given sequence is in Arithmetic progression ( A.P)
Step-by-step explanation:
Step(i):-
Given [tex]n^{th}[/tex] term of thesequence
f (n) = - 3n + 7
Put n = 1
first term a₁ = f (1 ) = - 3 (1 ) + 7 = - 3 + 7 = 4
Put n = 2
second term a₂ = f(2) = - 3 ( 2) + 7 = -6 +7 =1
Put n =3
Third term a₃ = f(3) = -3(3) +7 = -9 + 7 = -2
Put n =4
Fourth term a₄ = f(4) = -3(4) +7 = -12 + 7 = -5
Step(ii):-
The sequence of the given equation
4 , 1, -2 , -5, ......
first term a = 4 , d = 1 -4 = -3
The difference of two terms in this sequence is equal
∴ The given sequence is in Arithmetic progression ( A.P)
Final answer:-
The sequence of the given equation
4 , 1, -2 , -5, ......
∴ The given sequence is in Arithmetic progression ( A.P)

9c+1=10 i do not know the answer to this problem
Answer: To figure out the answer, you have to find c, c equals 0 because adding anything from 9 + 1 equaling 0 will get you above the answer, 10. so, 9c + 1 = 10, now lets change the equation to 9c(0) + 1 = 10, c equaling zero would make the most sense because if c equals 0 then you will get 10, the answer.

plzzz help .Which point is included in the graph of the ceiling function f(x) = [x]?
Answer: Choice C. (-3.5, -3)
========================================================
Explanation:
Draw a vertical number line. Make sure to plot the points -3 and -4 on this number line. We'll have -4 below -3. In between these values is -3.5
The ceiling function brings the point -3.5 up to -3. Think of an elevator that visits each floor of a skyscraper. Each floor being a positive or negative whole number on this number line. So when x = -3.5, this means f(x) = -3. This points to choice C being the answer.
As another example, if x = 5.7, then f(x) = 6. Yet another example would be x = 2.008 leads to f(x) = 3. We always move up to the closest integer.
Elijah buys P pounds of bananas for 60 cents per pound. He pays the clerk with a twenty-dollar bill. The clerk subtracts the total cost of the bananas from the twenty dollar bill to determine the amount of change to give Elijah.
Answer: (20-0.6P)
Step-by-step explanation:
Given: Elijah buys P pounds of bananas for 60 cents per pound.
Since 1 dollar = 100 cents
Then, 60 cents = [tex]\$\dfrac{60}{100}=\$0.6[/tex]
Cost of P pounds of bananas = Cost per pound x P
= $0.6 P
He pays the clerk with a twenty-dollar bill.
Change he will get = $ 20 - Cost of P pounds of bananas
= $ (20-0.6P)
Hence, the expression of the change Elijah will get = (20-0.6P)

a car start from rest and accelerates at the rate of 2m/s² for 5 seconds. it maintenance this velocity for another 5 seconds. it eventually undergoes a uniform deceleration and finally comes to rest after further 5 seconds.
A) draw the velocity-time graph for the journey
B) find the acceleration and deceleration respectively,
C) find the total distance travelled during each stage.
D) find the average velocity over the entire period
Answer:
2m/s² ; - 2m/s²
25m ; 50m ; 25m
6.67 m/s²
Step-by-step explanation:
The acceleration and deceleration :
Both rates are the Same from the graph ;
According to scenario described, acceleration = 2m/s²
Deceleration occurred in equal time interval = - 2m/s
Distance covered during each stage:
Stage 1 : area of triangle
0.5 * base * height
0.5 * 5 * 10 =25 m
Stage 2: area of rectangle :
Length * breadth = 5 * 10 = 50 m
Stage 3 : area of triangle
0.5 * base * height
0.5 * 5 * 10 =25 m
Average Velocity :
Total distance / time = (25 + 50 + 25) / 15 = 100/ 15 = 6. 67 m/s

Answer:
15 inches.
Step-by-step explanation:
Since we know its a square, we know that the side lengths are all equal. Knowing this, we know that we could find the area by taking a side length and squaring it. So we can take the square root of 219 to find the side length:
√219 = 14.79864859 ≈ 15
Therefore, the side lengths of the sign are about 15 inches.

Find the missing angle
Answer:
56deg
Step-by-step explanation:
A triangle has 180deg.
180 = 68 + 56 + x >> add 68 and 56
180 = 124 + x >> subtract 124 from both sides
56 = x
The missing side is 56deg

What is a system of equations?A finite collection of equations for which we searched for common solutions is referred to in mathematics as a system of equations, sometimes known as a set of simultaneous equations or an equation system. Similar to single equations, a system of equations can be categorized.
A linear equation can only have one unique solution, which is a location at which the LHS and RHS of the equation are equal. There is only ever one solution to a linear equation with one variable.
y = 5x - 1
y = 3x + 7
5x - 1 = 3x + 7
2x = 8
x = 4
y = 19
Therefore, there will be one unique solution of the equation y = 5x - 1 and y = 3x + 7.

Which of there polynomials could have (x-2) as a factor?
a(x) = 6x² - 7x - 5
b(x) = 3x² + 15x - 42
c(x) = 2x³ + 13x² + 16x + 5
d(x) = 3x³ - 2x² - 15x + 14
e(x) = 8x⁴ - 41x³ - 18x² + 101x + 70
f(x) = x⁴ + 5x³ - 27x² - 101x - 70
Answer:
x-2 is a factor of following polynomials:
b(x) = 3x² + 15x - 42d(x) = 3x³ - 2x² - 15x + 14 e(x) = 8x⁴ - 41x³ - 18x² + 101x + 70Step-by-step explanation:
In order to check that which polynomials might have x-2 as a factor, we will put
x-2 = 0 => x = 2 in each polynomial, if the value of polynomial on 2 is zero then x-2 is a factor otherwise not.
So,
a(x) = 6x² - 7x - 5
Putting x = 2
[tex]a(2) = 6(2)^2-7(2)-5\\= 6(4)-14-5\\=24-14-5\\=24-19\\=5 \neq 0[/tex]
b(x) = 3x² + 15x - 42
[tex]b(2) = 3(2)^2 + 15(2) - 42\\=3(4)+30-42\\=12+30-42\\=42-42 = 0[/tex]
c(x) = 2x³ + 13x² + 16x + 5
[tex]c(2) = 2(2)^3 + 13(2)^2 + 16(2) + 5\\=2(8)+13(4)+32+5\\=16+52+32+5\\=105 \neq 0[/tex]
d(x) = 3x³ - 2x² - 15x + 14
[tex]d(2) = 3(2)^3 - 2(2)^2 - 15(2) + 14\\= 3(8)-2(4)-30+14\\=24-8-30+14\\=38-38 = 0[/tex]
e(x) = 8x⁴ - 41x³ - 18x² + 101x + 70
[tex]e(2) = 8(2)^4 - 41(2)^3 - 18(2)^2 + 101(2) + 70\\= 8(16)-41(8)-18(4)+202+70\\=128-328-72+202+70\\=0[/tex]
[tex]f(2) = (2)^4 + 5(2)^3 - 27(2)^2 - 101(2) - 70\\=16+5(8)-27(4)-202-70\\=16+40-108-202-70\\=-324 \neq 0[/tex]
Hence,
x-2 is a factor of following polynomials:
b(x) = 3x² + 15x - 42d(x) = 3x³ - 2x² - 15x + 14 e(x) = 8x⁴ - 41x³ - 18x² + 101x + 70Please help on 4 5 and 6 both parts. Due in 30 min

if x+y=10 and x-y=6 what is this value of x cube - y cube
Answer:
x cubed minus y cubed is equal to 504
Step-by-step explanation:
First we need to know what the values of x and y are. We can do this pretty easily, by just solving both equations for x, and equating them to each other:
With the first:
x + y = 10
x = 10 - y
And with the other
x - y = 6
x = 6 + y
Now that we have two definitions of x, we can say that the expressions are equal, and solve for y:
10 - y = 6 + y
10 - 6 = y + y
4 = 2y
y = 2
And now that we know what y is, we can find x:
x = 10 - y
x = 10 - 2
x = 8
So x is equal to eight. We can check our answer by plugging x into the other equation and seeing if we get the same value for y:
x - y = 6
8 - y = 6
-y = 6 - 8
-y = -2
y = 2
So we know we solved that correctly.
Now if we cube each number, eight cubed is equal to 512, and 2 cubed is equal to 8. If we subtract the latter from the former we get 504.
so x cubed minus y cubed is equal to 504
