Answer:

x = 27

Step-by-step explanation:

From the picture attached,

m∠PLM + m∠PLK = 180° [Linear pair of angles are supplementary]

m∠PLM + 3x = 180°

m∠PLM = 180° - 3x

Similarly, m∠PML + m∠PMN = 180° [Linear pair of angles]

m∠PML + (2x + 72)° = 180°

m∠PML = 180° - (2x + 72)°

From triangle PLM.

m∠PLM + m∠PML + m∠LPM = 180° [Sum of interior angles of a triangle = 180°]

(180 - 3x) + 180 - (2x + 72) + x = 180

180 - 3x - 2x - 72 + x = 0

-4x + 108 = 0

x = [tex]\frac{108}{4}[/tex]

x = 27

because 0 is less than or equal to x and x is less than or equal to 75 ***** but use this answer at your own risk *****

The domain is the set of values for which the given function is defined. The domain of the given function is 0≤x≤7.5. The correct option is B.

The domain is the set of values for which the given function is defined.

The range is the set of all values which the given function can output.

Given that function b model the bagel inventory, b(x), after x hours of opening, and it is given as,

b(x) = 75 - 10x

Now, the domain of the function is the values that x can take in the function. Since x represents the number of hours after opening, therefore, it can not be negative and must start with zero.

Further, since the inventory or the total number of bagels that the shop has is 75, therefore, they can not sell more than that, and at some point, the inventory will become zero. Therefore, we can write,

75 - 10x = 0

-10x = -75

10x = 75

x = 75 /10

x = 7.5 hours

Hence, the domain of the given function is 0≤x≤7.5.

Answer:

the irrational numbers are all the real numbers which are not rational numbers.

Step-by-step explanation:

Let, x be the maximum hours he can rent skate board and helmet.

So, total price :

T = 4x + 6x

Now, it is given that he has only $30.

Therefore,

Total price should be less than or equal to $30.

4x + 6x ≤ 30

10x ≤ 30

x ≤ 3

Therefore, the maximum number of hours he can rent the skateboard is 3 hours.

Hence, this is the required solution.

Answer:

Quadratic coefficient = -14, linear coefficient = 168, constant term = -494

Step-by-step explanation:

Its easiest to first start out with a vertex form equation because it can then be converted to a standard quadratic.

given a vertex at (6,10) , and point of intersection at (7,-4), the equation can be set up like this:

y = a(x-6)^2+10, because we know h and k from the vertex.

We also know y and x from the given point of intersection so a can be solved.

-4 = a(7-6)^2+10

-4 = a + 10

-4-10 = a

a = -14 which is also known as the quadratic coefficient because it is part of a second degree quantity and a Trionomial as a whole(quadratic).

since all the variables are known, you can

expand the equation and set it to standard form

y = -14(x-6)^2+10

y = -14(x^2-12x+36)+10

y = -14x^2+168x-504+10

y = -14x^2+168x-494

For reference, the standard form equation is ax^2+bx+c where a is the quadratic coefficient, b is the linear coefficient, and c is the constant coefficient.

In this instance, -14x^2+168x-494 = ax^2+bx+c

Answer:

0.01364

Step-by-step explanation:

It is given that,

A store sells a 33-pound bag of oranges for $3.60 and a 55-pound bag of oranges for $5.25.

Price per pound of 33 pound bag is 3.60/33 = 0.10909 price per pound

Price per pound of 55 pound bag of oranges is 5.25/55 = 0.09545 price per pound

Difference between price per pound for the 33-pound bag of oranges and the price per pound for the 55-pound bag of oranges is :

D = 0.10909 - 0.09545

D = 0.01364

Therefore, this is the required solution.

Step-by-step explanation:

6h + 8r = 41.5

r=h-.85

6h + 8(h-.85)=41.5

6h + 8h - 6.8 = 41.5

14h = 41.5 + 6.8

14h = 48.3

h=48.3/14

h=3.45

Answer:

x= -31

Step-by-step explanation:

Let's solve your equation step-by-step.

3(2x−14)+x=15−(−9x−5)

Step 1: Simplify both sides of the equation.

3(2x−14)+x=15−(−9x−5)

3(2x−14)+x=15+−1(−9x−5)(Distribute the Negative Sign)

3(2x−14)+x=15+−1(−9x)+(−1)(−5)

3(2x−14)+x=15+9x+5

(3)(2x)+(3)(−14)+x=15+9x+5(Distribute)

6x+−42+x=15+9x+5

(6x+x)+(−42)=(9x)+(15+5)(Combine Like Terms)

7x+−42=9x+20

7x−42=9x+20

Step 2: Subtract 9x from both sides.

7x−42−9x=9x+20−9x

−2x−42=20

Step 3: Add 42 to both sides.

−2x−42+42=20+42

−2x=62

Step 4: Divide both sides by -2.

−2x

The resulting value for the given sum of trignometry identity is -2

Trigonometry identity are written in tems of sine, cosine and tangent

According to the trigonometry identity

sec theta = 1/costheta

cot theta = 1/tantheta

Given the trigonometry expression

sec 180 + sin 270 - tan 180 + cot 270

This can also be written as;

1/cos180 + sin270 - tan 180 + 1/tan270

= -1/cos0 + (-sin90)  - tan0 +1/tan90

= -1 - 1 - 0 +1/∞

= -1 -1 + 0
= -2

Hence the resulting value for the given sum of trignometry identity is -2

Answer:

[tex]y=\frac{-1}{6}x-\frac{10}{3}[/tex]

Step-by-step explanation:

Slope intercept form of the equation of a line is [tex]y=mx+b[/tex] where m denotes the slope of line and [tex]b[/tex] denotes the y-intercept.

Equation of a line u is [tex]y=6x+6[/tex]

Here, slope of line u = m = 6

As the line v is perpendicular to line u, product of slopes of both the lines is equal to [tex]-1[/tex].

Slope of line v  [tex]=\frac{-1}{6}[/tex]

So, slope intercept form of the line v is [tex]y=\frac{-1}{6}x+b[/tex]

As point [tex](10,-5)[/tex] lies on the line v, put [tex](x,y)=(10,-5)[/tex] in equation [tex]y=\frac{-1}{6}x+b[/tex]

[tex]-5=\frac{-1}{6}(10)+b\\-5=\frac{-5}{3}+b\\ -5+\frac{5}{3}=b\\\frac{-15+5}{3}=b\\\\\frac{-10}{3}=b[/tex]

Equation of line v is [tex]y=\frac{-1}{6}x-\frac{10}{3}[/tex]
