Find the slope of the line. 4y-2x= -30
Answer:
The slope is 1/2
Step-by-step explanation:
To find the slope of the line, put the equation in slope intercept form.
y= mx+b where m is the slope and b is the y intercept
4y -2x = -30
Add 2x to each side
4y -2x+2x = 2x-30
4y = 2x-30
Divide by 4
4y/4 = 2x/4 -30/4
y = 1/2x -15/2
The slope is 1/2
Answer:
0.5
Step-by-step explanation:
To find the slope of the line you have write this in slope intercept form.
That is,
y = mx + c.Here,
m - Slope
c - y intercept
Now, to write this expression in slope intercept form, you have to make y the subject of this expression.
[tex] 4y - 2x = - 30[/tex]
Add 2x to both sides.
4y = 2x - 30
Now divide both sides by 4.
y = 2/4x - 30/4
Accordingly,
[tex]y = 0.5x - 7.5[/tex]
Slope of the line (m) = 0.5

The value o x for the given expression will be 9.
The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the expression is 3x - y = 20 the value of y is 7. The value of x will be calculated as:-
3x - y = 20
3x - 7 = 20
3x = 20 + 7
3x = 27
x = 27 / 3
x = 9
Therefore, the value of x will be 9.

In a retail store with 36 employees, 29 work with customers, 11 work in the
warehouse, and 4 do neither. How many employees both work with customers and
work in the warehouse?
Answer: 8 employees doing both jobs.
Step-by-step explanation:
If 4 do neither, we can subtract this from the total number of employees. This will give us the employees that work with customers, the warehouse, or both.
36 - 4 = 32 employees
Next, we need to find how many do both. We can add 29 and 11 together to find the total number of jobs worked in these sections (this will include employees doing both jobs).
29 + 11 = 40 employees
Lastly, we will subtract the total number of employees working in these sections from the number above to find how many are doing both jobs.
40 - 32 = 8 employees doing both jobs.
Without graphing the equations, decide whether the system has one solution, no solution, or infinitely many solutions. 5y =x-6 4x-10y=12
Answer:
One solution:
[tex]\boxed{x = 0,\;y = -\dfrac{6}{5}}[/tex]
Step-by-step explanation:
The solution strategy is to isolate one of the variables by eliminating the other. There are several ways to do this. This is my preferred way
The equations are
[tex]5y = x-6 \cdots[1]\\\\4x - 10y = 12 \cdots[2]\\\\[/tex]
Transform equation [1] into the same form as [2] with x and y variables on the left and the constant on the right:
Subtract x from both sides of equation [1]:
[tex]-x + 5y = -6\cdots[3][/tex]
Multiply equation [3] by 2 to get the coefficients of y the same
[3] x 2 gives
[tex]-2x + 10 y = -12\cdots[4][/tex]
In equations [2] and [4], the coefficients of y are the same but of opposite sign
Add equations [2] and [4] to get
[tex]4x - 10y + (-2x + 10y) = 12 + (-12)\\\\4x - 10y -2x - 10y = 12 -12\\\\4x - 2x -10y + 10y = 0\\\\2x = 0\\\\x = 0\\\\[/tex]
Substitute for x = 0 in any of the equations [1] or [2] and solve for y
Let's pick equation 1
Substitute for x = 0 in [tex]5y = x - 6\\[/tex]
[tex]5y = 0 - 6\\\\5y = -6\\\\y = -\dfrac{6}{5}\\\\[/tex]
So this is a system of equations with one solution:

Okay so, if he is getting a console for $17.50, then you first want to do is subtract that from the total amount that he has which is $49.
49 - 17.50 = $31.50
Now each game costs $5.25
You can either just keep adding 5.25 by itself until you get to 31.50, or you can just divide 31.50 by 5.25, but I am going to just multiply then by certain numbers until I get the result.
5.25 * 5 = 26.25 so we know he can buy more than 5.
5.25 * 6 = 31.50

Police estimate that 20% of drivers do not wear their seatbelts. The police set up a safety roadblock and stopping cars to check for seatbelt use.
what is the probability that the first unbelted driver is in the 6th car stopped?
Answer:
20%
Step-by-step explanation:
The probability that the first unbelted driver is in the 6th car stopped is
(1 - 0.20)^5 * 0.20,
where 0.20 is the probability that a driver does not wear their seatbelt (20%),
and (1 - 0.20)^5 is the probability that the first 5 cars stopped all have drivers who wear their seatbelts.
This simplifies to (0.8)^5 * 0.2 = 0.32768 * 0.2 = 0.065536.
Complete the following statements with the correct words Note: Correct spelling is important. func a. If s(t) is a distance (or height or position) function, then s'(t) would be a velocity b. If c(x) is a cost function, then c'(x) would be called the cost x c. If y(t) is a velocity function, then v'(t) would be a acceleration function
Velocity, marginal cost, and acceleration are derivatives of displacement, cost, and velocity functions.
The velocity of an object or particle describes how far it has moved or displaced over time. If the function s(t) determines the position of an object, then the velocity is its first derivative. And, this is written as s'(t). The initial blank is therefore filled with velocity.
The cost difference between producing one more product or serving one more customer is known as the marginal cost. As a result, it can be calculated by dividing the change in overall costs by the change in energy output. So, the cost function's derivative is the marginal cost. If the cost function is c(x), then its derivative c'(x) is the marginal cost. The second blank is filled with marginal cost.
Acceleration is the time-dependent derivative of velocity. If v(t) is the velocity, then the acceleration is v'(t). The third blank is filled with acceleration.

x=cos(t)+cos(2t)
y=sin(t)+sin(2t)
(-1,1)
y=?
Equation of the tangent to the curve at point (-1,1) is: y=2x+3
Given,
x=cos(t)+cos(2t)
y=sin(t)+sin(2t)
P(-1,1)
For the point(-1,1), the value of t satisfy the equations x=cos(t)+cos(2t) and y=sin(t)+sin(2t) is pi/2.
To find an equation of the tangent to the curve at the given point (x,y) where x=cos(t)+cos(2t) and y=sin(t)+sin(2t) and t= pi/2, we need to first find the slope of the tangent line at this point. To do this, we need to take the derivative of the x and y functions with respect to t:
dx/dt = -sin(t) + 2sin(2t)
dy/dt = cos(t) - 2cos(2t)
Now we can use this information to find the slope of the tangent line at the given point (x,y) where x=cos(t)+cos(2t) and y=sin(t)+sin(2t) and t= pi/2:
slope = dy/dx = (cos(t) - 2cos(2t)) / (-sin(t) + 2sin(2t)) evaluated at t = pi/2
slope = (cos(pi/2) - 2cos(2pi/2))/(-sin(pi/2) + 2sin(2pi/2)) = 0 - (-2)/0 + 0 = 2
Now, we can use this slope to find the equation of tangent using:
(y-y1)= m(x-x1)

corporation.
Correct option is B and C, Stocks have higher risk than bonds. A bond offers fixed interest income, while a stock may offer dividends to investors.
In general, stocks are riskier than bonds simply because they do not provide investors with guaranteed returns, as opposed to bonds, which do so through coupon payments. Bondholders, who are a company's creditors, get priority in being paid back in the case of a business bankruptcy, making stocks intrinsically more volatile than bonds. Owners of common stock, on the other hand, are last in line and risk losing everything if the business fails.
Bonds would be a preferable choice for risk-averse investors who want to safely invest their money and feel secure with more standardized payout schedules.

14:7, 42:21, 6:3, 48:24
Step-by-step explanation:
The ratio can be seen as 2:1 (from the provided 14:7 which is equal to 2), which would be in plums:grapes.
Your ratio of 42:21 is correct for the second column, so we can move on to the third and fourth.
We can use this equation to find your missing values for column 3:
[tex]\frac{14}{7}[/tex] = [tex]\frac{x}{3}[/tex]
Now, we can solve for x through cross multiplication:
7x = 14*3
7x = 42
x = 6
For column 4, we can set up the equation:
[tex]\frac{14}{7}[/tex] = [tex]\frac{x}{24}[/tex]
Now, let's solve for x:
7x = 336
x = 48
Therefore, your ratios will be:
14:7, 42:21, 6:3, 48:24.
