Your bank account currently has a balance of $180. you withdraw $20 each week. write an equation that represents how many money (y) will be in your account x weeks. use your equation to find how many weeks until your account has a balance of zero.
The equation which represents money in the account after x weeks is:
20x+y=180
Hence the time after which the account has a balance of zero is 9 weeks.
Given, the bank account has a current balance of $180.
Withdrawal of $20 takes place every week.
we are asked to determine the amount of time (in weeks) needed for the account to have no balance is = ?
let x be the time time (weeks)
and y be the money left in the bank.
the equation will be:
20x + y = $180
Hence if the balance is zero, then how many weeks will it be.
substitute y=0
20x+0=180
20x=180
x=180/20
x=9
Hence it will take 9 weeks until the account has a balance of zero.

a large industrial firm purchases several new word processors at the end of each year, the exact num- ber depending on the frequency of repairs in the previ- ous year. suppose that the number of word processors, x, purchased each year has the following probability distribution:
This firm expects to spend on the new word processor expense of $1855 from the given probability distribution.
What is a probability distribution?
A random variable can have any number of alternative values and likelihoods within a particular range, and a probability distribution would be a statistical function that captures all of these possibilities. This range will be constrained by the minimum and maximum distinct combinations, but the location of the possible value on the probability distribution will rely on a number of other variables. These elements include the mean (median), and standard deviation, of the distribution.Given that the number of word processors, x, purchased each year has the probability distribution.
E(X)=1* (3/10)+2*(2/5)+3*(1/5)=1.7
E(X^2)=1^2(3/10)+2^2(2/5)+3^2(1/5)=3.7
Expense=E(1200x-50x^2)=E(1200x)+E(-50x^2)=1200E(x)-50E(x^2)
So
Expense=1200*1.7-50*3.7=1855
This firm expects to spend on the new word processor expense of $1855 from the given probability distribution.

In the first line, we are going to have that if you put 7 then to have the sum rigth the next space have to be 9, following that idea the space down of the 9 have to be also 7 and the first space on the second line have to be 19. So we are going to have 7 + 9 = 16 in the first line and in the second line 19 - 7 = 12, and the other two operations are going to be solve also 7 + 19 = 26 and 9 + 7 = 16.
Then the answer is 7 + 9 = 16 in the first line and in the second line 19 - 7 = 12.
the cube root of 64 is 4. how much larger is the cube root of 65.1? estimate using the linear approximation.
The exact difference is 0.022916
Given that the cube root of 64 is 4
We need to find how much larger is the cube root of 65.1 using the linear approximation.
Linear approximations:
They are ways to define a line tangent to a curve. At a particular range near the tangent point, the line can serve as an approximation for the function. However, linear approximations are determined through a combination of differentiation.
Here, when the tangent point is defined at x=a
then the linear approximation of a function is defined as f(x) ≈ f(a)+f′(a)(x−a)
Consider a = 64 f(x) = x^(1/3)
f'(x) = 1/3 x ^(-2/3)
So linear approximation is f(x) = 4 + 1/3 (64)^(-2/3) * (x-64)
x = 65.1
f(65.1) = 4 + 1/3 (64)^(-2/3) * (65.1 - 64)
f(65.1) - 4 = 1/3 1.1 (64)^(-2/3) = 1/3 * 1.1 * 1/16 = 1.1 / 48 = 0.0229
The exact difference is 0.022916

AX + 6939 + x4(G.CO.C.10)Solve for xFind the measure of angle A:
The sum of the angles of a triangle always equals 180°, then we can formulate the following expression:
(x + 69)° + (39 + x)° + 90° = 180°
By combining like terms in the above equation, we get:
x + x + 69 + 39 + 90 = 180
2x + 198° = 180°
We can solve for x to get:
2x + 198 - 198 = 180 - 198
2x = 180 - 198
2x = -18
x = -18/2
x = -9
Then, x equals -9.
In order to calculate the measure of angle A, we just have to replace the value of x into the equation 39 + x, then we get:
mmm
Then, the measure of angle A equals 30°.

An object is moving at a speed of 3 kilometers every 5 days. Express this speed in yards per hour.
An object is moving at a speed of 27.3 yards per hour.
How to find the speed in yards?3 kilometers must first be converted to yards.
1 m = 1.09 yards.
1 Km = 1093.61
3 km to yards is 3280.84
Currently, we must convert 5 days to hours. There are 24 hours every day, we shall multiply that number by 5 to find the number of hours in 5 days.
5 * 24 = 120 hours
To determine the speed in yards per hour, divide 3280.84 by 120.
3208.4/120
= 27.34 yards per hour
27.34 is 27.3 approximately.

Solve the quadratic equation by completing the square. x^2+8x+9=0First choose the appropriate form and fill in the blanks with correct numbers. Then solve the equation. If there is more than one solution, separate with commas.
The quadratic equation given in the question is
[tex]x^2+8x+9=0[/tex]Step 1: Keep x terms on the left and move the constant to the right side by subtracting 9 on both sides
[tex]\begin{gathered} x^2+8x+9=0 \\ x^2+8x+9-9=0-9 \\ x^2+8x=-9 \end{gathered}[/tex]Step 2: Take half of the coefficient of the x term and square it
The coefficient of the x term is 8
[tex]\begin{gathered} (8\times\frac{1}{2})^2 \\ =(\frac{8}{2})^2 \\ =4^2 \\ =16 \end{gathered}[/tex]Step 3: Add 16 to both sides in the equation in step 1
[tex]\begin{gathered} x^2+8x=-9 \\ x^2+8x+16=-9+16 \\ x^2+8x+16=7 \\ \end{gathered}[/tex]Step 4: Re-write the perfect squares on the left
[tex]\begin{gathered} x^2+8x+16=7 \\ (x+4)^2=7 \\ \text{Which will give us } \\ (x+4)^2-7=0 \\ (x+4)^2=7 \end{gathered}[/tex]Hence,
We will have (x+4)²=7
To solve for the value of x, we will equate to zeros and make x the subject of the formula
[tex](x+4)^2=7[/tex]Step 5: Add 7 to both sides
[tex]\begin{gathered} (x+4)^2-7+=0+7 \\ (x+4)^2=7 \end{gathered}[/tex]Step 6: Square root both sides
[tex]\begin{gathered} (x+4)^2=7 \\ \sqrt[]{(x+4)}^2=\sqrt[]{7} \\ (x+4)=\pm\sqrt[]{7} \\ \end{gathered}[/tex]Step 7: Isolate the x on the left side and solve for x by subtracting 4 from both sides
[tex]\begin{gathered} (x+4)=\pm\sqrt[]{7} \\ x+4-4=\pm\sqrt[]{7}-4 \\ x=\pm\sqrt[]{7}-4 \\ \text{therefore,} \\ x=-4+\sqrt[]{7} \\ x=-4-\sqrt[]{7} \end{gathered}[/tex]Therefore,
The value of x is

The current I in an electrical conducter varies inversely as the resistance R of the conducter. The current is 1/6 ampere when the resistance is 36288 ohms. What is the current when the resistance is 49392 ohms?
The current when the resistance is 49392 ohms is 0.122 amperes.
If a current passes through two points is directly proportional to voltage and inversely proportional to the resistance.
The ohm's law is V=IR
Here V is the voltage, I is the current and R is the resistance.
Here we need to find the current flow through the conductor. The unit of current in amperes.
The current is I = 1/6 amperes when resistance is R = 36288 ohms.
To find voltage :
I = V/R
1/6 = V/36288
6V = 36288
V = 36288/6
V = 6048
Therefore, the voltage is 6048 volts.
Now, the current when the resistance is R = 49392 ohms:
I = V/R
I = 6048/49392
= 0.122 amperes.
Hence the current is 0/122 amperes.

0Is (2, 9) a solution to these simultaneous equations?
y = 3x + 3
y = x + 7
==============================================
Explanation:
The given solution is (2,9) which means x = 2 and y = 9 pair up together.
Replace x with 2 and replace y with 9.
Let's do so for the first equation
y = 3x+3
9 = 3*2+3
9 = 6+3
9 = 9
We get the same thing on both sides, which confirms the first equation.
Now let's check the second equation.
y = x+7
9 = 2+7
9 = 9
This equation is confirmed as well.
Both equations are true when (x,y) = (2,9) which confirms it is indeed the solution to the system.
----------------------------
If you are a visual learner, then I recommend graphing out the equations using a tool like GeoGebra or Desmos.
The two lines intersect at (2,9) which visually confirms it is the solution.
Draw a line representing the rise and a line representing the run of the line. State the slope of the line in simplest form.
The slope of the line is 7 x - 8 y + 56 = 0 0r 8 y = 7x - 56
What does it mean by slope of a line ?
The ratio of the difference between the y- and x-coordinates of the two points that make up the line must be calculated. The slope of the line is the value that is obtained. It displays how the line's y-axis climb compares to its x-axis run.
Given : The two points are A( 0, 7 ) and B ( -8 , 0 )
The formula of the slope of the line is
y₂ - y₁ = m ( x₂ - x₁ )
And m = y₂ - y₁ / x₂ - x₁
m = - 7 / - 8 = 7/8
therefore , y - 0 = 7/8 ( x + 8 )
8 y = 7x + 56
