In order to find the shaded region the first thing you have to do is find the area of the two small triangles, then find the area of the big triangle. Subtract the area of the small triangles from the big one and that is the area.

Step one: 11×12=132

Step two: 132÷2= 66

Step three: 66+66=132 (because there is two small triangles with same dimensions)

Step four: 40×15=300

Step five: 300-132=168

x=Mike's age

y=Dan's age

It is given that,Mike is three years older than dan.

→ x=y+3

If you will draw the graph of the function, it will cut x axis at (3,0) and y axis at (0,-3).

⇒Graph-2

The graph that represents the relationship between Mike's age and Dan's age (y), is Option A with a positive slope of 1.

The relationship between Dan's age and Mike's age can be represented by a linear equation, where Mike's age (x) is three years older than Dan's age (y).

Therefore, the graph that represents this relationship would be a straight line with a positive slope of 1 and a y-intercept of -3.

The equation for this relationship would be:

x = y + 3

Answer:

a) Parallel when a = -2/3

b) Perpendicular when a = 6

Explanation:

a)  For two parallel lines slopes are equal.

  So, 6y=−2x+4 and 2y=ax−5 parallel if they are slopes equal.

  Slope of 6y=−2x+4, comparing with y = mx + c

     So, m = -2/6 = =-1/3

  For 6y=−2x+4 and 2y=ax−5 to b parallel we have slope of 2y=ax−5 equal to -1/3

   Slope of 2y=ax−5

           m = a/2

    We have a/2 = -1/3

                    a = -2/3

b) For perpendicular lines product of slope is -1.

   So we have

               [tex]\frac{a}{2} *\frac{-1}{3} =-1\\ \\ a=6[/tex]    

The value of 'a' that would make the graphs of the equations 6y = -2x + 4 and 2y = ax - 5 parallel is -1/3. Meanwhile, the value of 'a' that would make them perpendicular is 3.

The question you've asked is about finding the values of a for which two graphs represented by the equations 6y = -2x + 4 and 2y = ax - 5 are either parallel or perpendicular. To solve this, we need to understand and apply the concept of slope in straight-line equations.

Firstly, rewrite the given equations in the form of y = mx + b, where m is the slope. For the first equation, it becomes y = -1/3x + 2/3, so the slope is -1/3.

Parallel lines have the same slope. Therefore, the value of 'a' for the second equation to be parallel with the first needs to be -1/3. Conversely, perpendicular lines have slopes that multiply to -1. Thus, for the second line to be perpendicular to the first, 'a' would have to be the negative reciprocal of -1/3, which is 3.

Function 1:

For the given table

[tex]\begin{array}{cc}x&f(x)\\-2&-2\\-1&1\\0&4\\1&7\end{array}[/tex]

you can plot the graph of the function (see first attached diagram). This function is linear and has equation f(x)=3x+4.

Function 2:

For the given function f(x)=-2x+3 you can create a table

[tex]\begin{array}{cc}x&f(x)\\-2&7\\-1&5\\0&3\\1&1\end{array}[/tex]

The question deals with linear functions representation.For each given linear representation, create two additional: table values and a graph. Use the given information, like equation or table values or a graph, to calculate other forms.

This assignment deals with creating matching cards for linear functions. For each linear function, you'll need to obtain two additional representations. Firstly, you should find the table of values which means identifying various x and y values that satisfy the function. For instance, if your given function is y = 2x + 3, just substitute different values into x and find the corresponding y-values.

Second is to derive the graph. You can do this by plotting the points you obtained for your table of values on a graph. You'll notice that all these points will fall on a straight line as it is a linear function.

The provided representation will guide you while creating your table and graph. For instance, if you are given the equation, figure out the slope and y-intercept because they're crucial to draw the graph and construct the table.

If presented with the table values, find the rate of change, which will be the slope, and a point on the table which gives you the y-intercept and hence give you an equation. Finally, if given a graph, find two points on the line then apply the slope-intercept form to find your equation and table values.

To find Roy's total frequent flyer miles, add his current miles (10,368), the miles he'll earn from his trip to New York (2,832) and the miles he'll earn from his credit card spending (2 miles per dollar spent). The final expression for total miles is 13,200 + 2d where 'd' is the amount spent using the credit card.

Roy's total frequent flyer miles can be calculated by adding his existing miles, his incoming miles from his trip to New York, and the miles gained from using his credit card. Let's assume he spends 'd' dollars using his credit card.

Firstly, we combine the miles he already has and those he will earn from his round trip: 10,368 miles + 2,832 miles = 13,200 miles.

Secondly, we consider his credit card earnings. As he gains 2 miles per dollar spent, he will earn '2d' miles from his credit card spendings.

Finally, we add these together to get the total frequent flyer miles he will have: 13,200 miles + 2d miles. Therefore, the total miles that Roy will have depends on the amount 'd' he spends on his credit card.

Answer:

Don have 15 markers.

Step-by-step explanation:

Don has 5 more pencils than crayons.

Let the number of crayons Don has = 7

Answer:

Rhea makes $2295 every month.

Step-by-step explanation:

In order to find this, we have to note that one-third of her salary is equal to $765. Give that fact, we know multiplying her rent total by 3 would give us the total salary.

$765 * 3 = $2295

answer: 20

work:

okay, so to solve this, set up as a system of equations and solve:

[tex]\frac{3}{5} = \frac{12}{x}[/tex]

this equation models our problem, because it shows the 3 to 5 ratio and out 12 to x, the number we're trying to find.

so, to solve, cross multiply

3(x) = 5(12)

3x = 20

x = 20

so, when there are 12 oranges, there are 20 pics total.

checking the answer:

the original equation states that "Three out of every five picks are orange" so, this means we can represent this as a fraction, 3/5.

to verify if our other fraction, which we can model as 12/20 is correct, we can simplify it, and if it's equivalent to 3/5 we know it's correct.

so, to simplify we need to find the greatest common factor between 12 and 20 so we can divide both numbers by this fraction.

well, the greatest common factor between these two numbers is 4, so divide both of them by 4.

[tex]\frac{12}{20}[/tex] ÷ [tex]\frac{4}{4} = \frac{3}{5}[/tex]

so, this verifies my answer is correct. hope this helps, and have an amazing day!

The expression (y^2)^3 can be rewritten as y^6 using the rule of exponents that states when you raise a power to a power, you multiply the exponents.

The expression (y^2)^3 can be rewritten in the form of y^n using the rule of exponents which states that when you raise a power to a power, you multiply the exponents.

The number 44 is 11 percentage of the number 400, and the correct option is B) 44 = 0.11 * x ; 400

Given data:

The first number is represented as p.

The value of p = 44

The second number is represented as q.

The value of q = q

So, the percentage of the number is A = 11 %, where A = ( p/q ) * 100

On simplifying the equation:

11 = ( 44/q) * 100

q = 4 * 100

q = 400

Hence, the number is 400.

Answer:

Step-by-step explanation:

y - y₁ = m(x - x₁)

y₁ = 7; x₁ = -15

y - (7) = (-1/2)(x - (-15))
