Answer:
let the number be " x "
[tex]\bold{x - 5 = 2(x + 9)} \\\bold{ x - 5 = 2x + 18 } [/tex]
gathering the like terms together , we get
[tex]\bold{2x - x = - 5 - 18} \\\bold{ x = - 23}[/tex]
hope helpful~
Answer:
The answer is going to be 7 or X=7. Here is how that conclusion came to be. Five less than twice a number is 9; here is the mathematical sentence we created to represent the statement:
2X-5=9 now lets work it.
2X-5+5=9+5
2X=14 , lets divide boyh sides of the equation by 2.
2X/2=14/2
X=7 Now lets prove this number represents X.
2(7)-5=9
14–5=9
9=9

Answer:
No solution
Step-by-step explanation:
The slopes of both equations are identical (both being 2/3), therefore the only possible answers would be "infinitely many solutions" and "no solution". Because of the fact that the y-intercepts of the equations are different (-10 and 10) they two lines will never cross, meaning there is no solution.
Answer:
no solution
Step-by-step explanation:
[tex]\frac{2}{3} x - 10 = \frac{4}{6} x + 10[/tex]
Reduce the fraction:
[tex]\frac{2}{3} x - 10 = \frac{2}{3} x + 10[/tex]
Rearrange variables to the left side of the equation:
[tex]\frac{2}{3} x - \frac{2}{3} x = 10 + 10[/tex]
Apply the inverse property of addition
0 = 10 + 10
0 = 20
Based on the given conditions, the system of equations has no solution.

A plane is descending from an altitude of 8,000 feet. The plane
descends at a constant rate of 500 feet per minute.
Which function can be used to determine the height, H, of the plane
after m minutes?
The linear function that can be used to determine the height, H, of the plane after m minutes is given by:
H(m) = 8000 - 500m
What is a linear function?A linear function is modeled by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value.In this problem:
The plane is descending from an altitude of 8,000 feet, hence the y-intercept is b = 8000.The plane descends at a constant rate of 500 feet per minute, hence the slope is of m = -500.Thus, the equation is:
H(m) = 8000 - 500m.

Suppose you roll a number cube. What is the probability that you roll a number greater than 1?
Answer:
Ok a cube has 6 sides and the choices are 1,2,3,4,5,6. As you can see you need to know the probability getting greater than 1. So 2,3,4,5,6 are greater so, the answer would be 5/6 into percentage around 83% of getting greater than 1.

Antonio's sister has challenged him to find the sum of the 23rd through 40th terms of the series. Help
Antonio by finding this value. Explain your reasoning and show your work below.
The function A(n) = 22(1.1)^n-1 is an illustration of a geometric series
The sum of the 23rd through 40th terms of the series is 17.49
How to determine the sum of the seriesThe nth term of the geometric series is given as:
[tex]A(n) = 22(1.1)^{n-1[/tex]
The nth term of a series is represented as:
[tex]A(n) = ar^{n-1[/tex]
So, by comparison;
We have:
[tex]a = 22[/tex]
[tex]r = 1.1[/tex]
The sum of nth term of a geometric progression is:
[tex]S_n = \frac{a(r^n - 1)}{r - 1}[/tex]
Start by calculating the sum of the first 22 terms
[tex]S_{22} = \frac{22(1.1^{22} - 1)}{22 - 1}[/tex]
[tex]S_{22} = \frac{157.086}{21}[/tex]
[tex]S_{22} = 7.48[/tex]
Next, calculate the sum of the first 40 terms
[tex]S_{40} = \frac{22(1.1^{40} - 1)}{40 - 1}[/tex]
[tex]S_{40} = \frac{973.70}{39}[/tex]
[tex]S_{40} = 24.97[/tex]
Subtract S22 from S40
[tex]S_{40} - S_{22} = 24.97 - 7.48[/tex]
[tex]S_{40} - S_{22} = 17.49[/tex]
Hence, the sum of the 23rd through 40th terms of the series is 17.49

Using simple interest, it is found that the monthly payment for this loan is of $325.485.
Simple InterestSimple interest is used when there is a single compounding per time period.
The amount of money after t years in is modeled by:
[tex]A(t) = A(0)(1 + rt)[/tex]
In which:
A(0) is the initial amount.r is the interest rate, as a decimal.In this problem, the parameters are A(0) = 8100, r = 0.0822, t = 2.5, hence, the total amount is:

Find the co-ordinate of the point where y-4x=1 crosses the y-axis
Answer: (0,1)
Step-by-step explanation:
When a line crosses the y-axis, the x-coordinate must equal to 0.
Now we can plug in x = 0 into the equation given:
y - 4*0 = 1
y- 0 = 1
y = 1
Therefore, the point where the line crosses the y-axis is (0,1)

True or False The Solutions, Roots, X-intercepts and zeros of a quadratic equation are all the same thing? why
Yes, solutions, roots, x-intercepts, and zeros are the same thing.
What is a quadratic equation?
The general quadratic equation is given by:
a*x^2 + b*x + c = 0
So the solutions are the values of x such that the above thing is zero.
On another hand, a parabola or a quadratic function is given by:
a*x^2 + b*x + c = y
The roots, zeros, or x-intercepts (these represent the same thing) are given by:
a*x^2 + b*x + c = 0
Zero or Root means that when you evaluate the function in that value the outcome is zero.X-intercept means that for that value of x, the function intercepts the x-axis, so the function is equal to zero.So these are the values of x such that the function becomes equal to zero, so these are exactly the same thing as the solutions of a quadratic equation.
Concluding, yes, solutions, roots, x-intercepts, and zeros are the same thing.
