3(0.4h+5)=4(0.2h+7)

When adding extraneous information or an aside to a sentence, parentheses, a pair of punctuation marks, are most frequently utilized.

Two curving vertical lines can be seen in parentheses: ( ). Parenthesis refers to a single instance of this punctuation.

To the left, we reposition every term:

3(0.4h+5)-(4(0.2h+7))=0

Parentheses are increased.

0h-(4(0.2h+7))+15=0

-(4(0.2h+7)), which we calculate as follows:

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,

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

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.

Answer:

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

The lines y = x + 3 and y = 2 · x + 2 pass through point (1, 4) on Cartesian plane.

In this problem we must graph two lines that pass through point (x, y) = (1, 4). Lines can be represented by equations of following form:

y = m · x + b

Where:

We must choose two slope-intercept combinations to generate two different lines: (x, y) = (1, 4)

Line 1

4 = m · 1 + b

4 = m + b

m = 1

4 = 1 + b

What is equation ?

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

A mathematical statement known as an equation is made up of two expressions joined together by the equal sign. A formula would be 3x - 5 = 16, for instance. When this equation is solved, we discover that the value of the variable x is 7.

A mathematical expression with an equals sign is referred to as an equation. Algebra is widely used in equations. When performing calculations but unsure of the precise amount, algebra is used.

Answer:

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:

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:
[tex]\boxed{x = 0,\;y = -\dfrac{6}{5}}[/tex]

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.

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)

=> y-1=2(x+1)

=>y=2x+3
