9c+1=10 i do not know the answer to this problem
Answers
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.

if x+y=10 and x-y=6 what is this value of x cube - y cube
Answers
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

y - 2 = 3(x - 6)
y - 2 = 3x - 18
y = 3x - 16
4.)
y - (-2) = 3(x - 5)
y + 2 = 3x - 15
y = 3x - 17
3.)
y - 7 = 2(x - 4)
y - 7 = 2x - 8
y = 2x - 1

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.
Answers
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)

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
Answers
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 + 70How many solutions does this system have?

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.

If you put $6.24 into a savings account that earns 5%, how much money will you have in the bank at the end of four years? Please show step by step
Answers
Answer:
$7.488 or $7.49 (rounded)
Step-by-step explanation:
In order to find the amount of money at the end of 4 years, you have the find the amount of money after one year. So, the first step is to multiply 6.24 by .05 to get the percent gained in one year. This is .312. Then, you multiply the amount from the first year by four, for the other years, and get 1.248. That is how much you will earn in four years. Now, to get the total of all the money in the bank account after four years, you add 1.248 to 6.24. This sums up to 7.488 which is your answer. Hope this helps :)

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

plzzz help .Which point is included in the graph of the ceiling function f(x) = [x]?
Answers
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.
