Given:

The equation of a line is

[tex]y=\dfrac{3}{4}x-11[/tex]

Line v passes through point (6,6) and it is perpendicular to the given line.

Line w passes through point (-6,10) and it is parallel to the line v.

To find:

The equation in slope intercept form of line w.

Solution:

Slope intercept form of a line is

[tex]y=mx+b[/tex]         ...(i)

where, m is slope and b is y-intercept.

We have,

[tex]y=\dfrac{3}{4}x-11[/tex]      ...(ii)

On comparing (i) and (ii), we get

[tex]m=\dfrac{3}{4}[/tex]

So, slope of given line is [tex]\dfrac{3}{4}[/tex].

Product of slopes of two perpendicular lines is -1.

[tex]m_1\times m_2=-1[/tex]

[tex]\dfrac{3}{4}\times m_2=-1[/tex]

[tex]m_2=-\dfrac{4}{3}[/tex]

Line w is perpendicular to the given line. So, the slope of line w is [tex]-\dfrac{4}{3}[/tex].

Slopes of parallel line are equal.

Line v is parallel to line w. So, slope of line v is also [tex]-\dfrac{4}{3}[/tex].

Slope of line v is [tex]-\dfrac{4}{3}[/tex] and it passes thorugh (-6,10). So, the equation of line v is

[tex]y-y_1=m(x-x_1)[/tex]

where, m is slope.

[tex]y-10=-\dfrac{4}{3}(x-(-6))[/tex]

[tex]y-10=-\dfrac{4}{3}(x+6)[/tex]

[tex]y-10=-\dfrac{4}{3}x-\dfrac{4}{3}(6)[/tex]

[tex]y-10=-\dfrac{4}{3}x-8[/tex]

Adding 10 on both sides, we get

[tex]y=-\dfrac{4}{3}x-8+10[/tex]

[tex]y=-\dfrac{4}{3}x+2[/tex]

Therefore the equation of line v is [tex]y=-\dfrac{4}{3}x+2[/tex].

Answer:

So, how do we check to see if two functions are inverses of each other? Well, we learned before that we can look at the graphs.

Step-by-step explanation:

Remember, if the two graphs are symmetric with respect to the line y = x (mirror images over y = x ), then they are inverse functions.

Answer:

the final cost will be about $56.81

Step-by-step explanation:

Here is the price after taxes:

8% of 52.60 = 4.20800

Now add that to the real price:

52.60 + 4.20800 = 56.808

Round to nearest tenth:

56.808 = about $56.81

Answer:

X = 70 (red)

Step-by-step explanation:

all three angles of a triangle equall 180

so 180 - (30+80) = x

180 - 110 = 70

Answer:

The mixed number for the amount of cupcakes mark ate is 1 1/6

Step-by-step explanation:

On his birthday mark ate 2/3 of a chocolate cupcake 1/4 of a red velvet cupcake and 1/2 of a vanilla cupcake. How many total cupcakes did mark eat on his birthday?

What is the mixed number for the amount of cupcakes mark ate?

This is solved as:

2/3 of a chocolate cupcake + 1/4 of a red velvet cupcake + 1/2 of a vanilla cupcake.

2/3 + 1/4 + 1/2

The Lowest Common Denominator is 12

8 + 2 + 4/12

= 14/12

= 7/6

= 1 1/6

Answer:

  not a function

Step-by-step explanation:

When any x-value (input) maps to more than one y-value (output), the relation is not a function.

Here, 9 maps to 2 different y-values (4 and 5), so the relation is not a function.

You have the slope and you have two points, so you can use the slope equation to find x.

[tex]b=\frac{(y_2-y_1)}{(x_2-x_1)} \\2=\frac{(15-5)}{(x-3)} \\2(x-3)=(15-5)\\2x-6=10\\2x=16\\x=8[/tex]

So your answer is x = 8.

Answer:

x =7

Step-by-step explanation:

slope m = ( y2-y1) / (x2-x1)

for points (3,5) and (x,15)

that will be m= (5-15)/(3-x)

so (5-15)/(3-x) =2

-10 / (3-x) = 2 / 1 cross multiply

-10 = 2(3-x)  divide both sides by 2

-5 = 3 -x

x= 3+5 =8

Answer:

g(n)= 3^n x 10

Step-by-step explanation: The numbers are increasing exponentially and are being multiplied by 30.  Since it's not a linear rate of change, it is going to be exponential, so 3 to the n power or whatever week number times 10 will give you the amount of guppies after a specific amount of weeks!

The explicit equation for the number of guppies is: [tex]\mathbf{y = 10 \times 3^x}[/tex]

The table is an illustration of an exponential model.

An exponential model is represented as:

[tex]\mathbf{y = ab^x}[/tex]

Let x represents the number of weeks, and y represents the number of guppies.

When x = 0, y = 10

So, we have:

[tex]\mathbf{10 = ab^0}[/tex]

[tex]\mathbf{10 = a \times 1}[/tex]

[tex]\mathbf{10 = a}[/tex]

Rewrite as:

[tex]\mathbf{a = 10 }[/tex]

When x = 1, y =30

So, we have:

[tex]\mathbf{30 = ab^1}[/tex]

[tex]\mathbf{30 = ab}[/tex]

Substitute 10 for (a)

[tex]\mathbf{30 = 10b}[/tex]

Divide both sides by 10

[tex]\mathbf{3 = b}[/tex]

Rewrite as:

[tex]\mathbf{b = 3 }[/tex]

Substitute 3 for b and 10 for (a) in [tex]\mathbf{y = ab^x}[/tex]

Hence, the explicit equation is: [tex]\mathbf{y = 10 \times 3^x}[/tex]

Answer:

Parallel

Step-by-step explanation:

For two lines to be parallel, they must have the same slope.

These are linear equations, which are represented by [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept.

In this pair of equations, we can see that the m (or the slope) are exactly the same ([tex]-\frac{1}{2} = -\frac{1}{2}[/tex]). This means that they are parallel.

Two lines are perpendicular when the slope of one of them is equal to the negative reciprocal of the other.

For example, to find the perpendicular line to [tex]y=-\frac{1}{2}x+5[/tex] we would get the m ([tex]-\frac{1}{2}[/tex]) and find its negative reciprocal.

[tex]-(-\frac{2}{1}) = 2[/tex]

We can verify this graphically by using a calculator (if you have a graphing calculator) or we can use the Desmos tool (online graphing calculator). Please see the image that's attached to this answer. It's evident that they are perpendicular in this image due to the fact that they make an angle of 90 degrees.

Answer:

3

Step-by-step explanation:

The Pythagorean Theorem can be used to determine an unknown side of a right triangle when two sides are known.

It states that a^2+b^2=c^2.

This is where a and b are the legs of the triangle, and c is the hypotenuse.

If you're unclear on this, you can draw a diagram to help you visualize it.

Hence, we can plug the given information into this formula.

a^2+8^2=(√73)^2

Simplify.

a^2+64=73

Subtract 64 from both sides.

a^2+64-64=73-64

a^2=9

Find the square root of both sides.

a=3

The length of the unknown leg in the right triangle is 3 units.

6x^5 - 8x^4 + 9x^3 - 15x^2 + 4x

Step-by-step explanation:

(3x^2 - 4x)(2x^3 + 3x - 1)

Multiply the second parentheses by each term from the first parentheses

3x^2(2x^3 + 3x - 1) -4x(2x^3 + 3x - 1)

Distribute 3x^2 through the first parentheses

6x^5 + 9x^3 - 3x^2

then distribute -4x through the second parentheses

-8x^4 -12x^2 + 4x

put them together

6x^5 + 9x^3 - 3x^2 - 8x^4 -12x^2 + 4x

combine the bolded like terms above

6x^5 + 9x^3 - 15x^2 - 8x^4 + 4x

use the commutative property to reorder the terms.

6x^5 - 8x^4 + 9x^3 - 15x^2 +4x

Answer:

1.68 gallons.

Step-by-step explanation:

So, without mincing words let's dive straight into the solution to the problem above. We are given from the question that the person that is Summet make use of gasoline to mow lawns and the amount of gasoline that Summet uses per hour = 0.4 gallon.

If Summet uses 0.4 gallon of kerosene in 1 hour. Then, Summet will use x gallons of gasoline in 4.2 hours, that is:

0.4  -----------------------> 1 hour.

x ---------------------------> 4.2 hours. Then,

x = 4.2 × 0.4 = 1.68 gallons of gasoline.

Hence, Summet uses 1.68 gallons of gasoline in 4.2 hours.

Answer:

x = 47 degrees

y = 86 degrees

Step-by-step explanation:

X and 47 are both congruent angles making x = 47. The angles of a triangle all add up to equal 180 degrees meaning you need to do 180-47-47 to figure out the missing angle of y. 180-47-47=86 aka angle y.

86+47+47=180
