Answer:

x = 59

Step-by-step explanation:

Since the angles of a quadrilateral add up to 360°, simply set the sum of all the angles to 360°:

x + x + (2x + 3) + (2x + 3) = 360

Combine like terms:

2x + 4x + 6 = 360

6x + 6 = 360

Get the x's on one side:

6x = 360 - 6

6x = 354

Solve by dividing by 6:

x = 59

Answer:

59

Step-by-step explanation:

x + x + (2x + 3)° + (2x + 3)° = 360°

6x + 6 = 360

6x = 354

x = 59

Answer:

Step-by-step explanation:

This is a Pythagorean Theorem Question

c^2 = a^2 + b^2

c= sqrt(5)

a = x

b = x            This is an isosceles right triangle. The vertical side and the horizontal side are equal.

x^2 + x^2  =  sqrt(5)^2

2x^2 = 5                           Divide both sides by 2

x^2 = 5/2                          Take the sqrt of both sides.

√x^2 = √5 / √2                Multiply right side by √2 on both top and bottom

x = √5*√2 / √2*√2

x = √10 /2

Answer:

Slope = 2

Step-by-step explanation:

Slope = [tex]\frac{y_{2} -y_{1}}{x_{2}-x_{1}}[/tex]

Slope = [tex]\frac{-11 -(-1)}{4-9} = \frac{-10}{-5} = 2[/tex]

Answer:

x = -6, 10

Step-by-step explanation:

Hi there!

[tex]f(x)=x^2-4x-60[/tex]

Let f(x) = 0:

[tex]0=x^2-4x-60[/tex]

Factor the equation:

[tex]0=x^2-10x+6x-60\\0=x(x-10)+6(x-10)\\0=(x+6)(x-10)[/tex]

The zero-product property tells us that when two terms are multiplied and they equal zero, one of the terms must be zero.

Therefore, either (x+6) or (x110) is equal to 0:

x+6 = 0 ⇒ x = -6

x-10 = 0 ⇒ x = 10

Therefore, the zeros of f(x) are -6 and 10.

I hope this helps!

Answer: -6 and 10

Step-by-step explanation: took the test and got 100%

To solve the problem we must know about Sine Rule.

The sine rule of trigonometry helps us to equate the side of the triangles to the angles of the triangles. It is given by the formula,

[tex]\dfrac{Sin\ A}{\alpha} =\dfrac{Sin\ A}{\beta} =\dfrac{Sin\ A}{\gamma}[/tex]

where

The value of w is 4.0 cm.

Given to us

[tex]\dfrac{Sin\ A}{\alpha} =\dfrac{Sin\ A}{\beta} =\dfrac{Sin\ A}{\gamma}[/tex]

Substitute the values,

[tex]\dfrac{Sin\ W}{w} = \dfrac{Sin\ U}{VW}[/tex]

[tex]\dfrac{Sin\ 39^o}{w}=\dfrac{Sin\ 31^o}{3.3}[/tex]

[tex]w=\dfrac{(Sin\ 39^o) \times 3.3}{Sin\ 31^o}[/tex]

w = 4.03224 cm ≈ 4.0 cm

Hence, the value of w is 4.0 cm.

Answer:

f(x) and g(x) have the same y-intercept

Step-by-step explanation:

the y-intercept is the point, where the graph intersects the y-axis.

and what is the definition of the y-axis ? it is

x = 0

for all the values up and down the y-axis, their x-coordinate is 0.

so, to find the y-intercept we find the functional value for x = 0.

and that is here in both cases : -32

and the y-intersect point is therefore for both functions:

(0, -32)

1/2 = 0.5 / 1/2 of 100 is 50

Step-by-step explanation:

I am not sure what you are trying to say here but I will tell you what I know:

1/2 is equal to 0.5

So 50 x 1/2 = 25  
And 50 x 0.5 = 25

So 100 x 0.5 = 50

The first mistake Bailey made was in the reason he gave for the first statement. he should have written: reflexive property.

The reflexive property of congruence states that an angle will always be equal or congruent to itself.

For example, given an angle, ∠B, therefore:

∠B ≅ ∠B

In the diagram given, based on the reflexive property of congruence, ∠F ≅ ∠F.

Therefore, the first mistake Bailey made was in the reason he gave for the first statement. he should have written: reflexive property.

Answer:

1. 3750 millimetres

,,...

Answer:

1)A centimetre (international spelling) or centimeter (American spelling) (SI symbol cm) is a unit of length in the metric system, equal to one hundredth of a metre, centi being the SI prefix for a factor of 1100.

2)1000 ml

We know that 1 litre = 1000 ml, hence, the conversion factor that is used to convert liters to millilters is 1000.

3)My Solution:

Empty the 3-liter bowl, and then transfer the 2 liters from the 5-liter bowl into it. Now fill the 5-liter bowl again, then pour water carefully from the 5-liter bowl into the 3-liter bowl until it is full - exactly one more liter. The 5-liter bowl now has exactly 4 liters.

The equation and each day spend on snacks are 5(x + 4.5) = 28.75 and 1.25.

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

Simplification is to make something easier to do or understand and to make something less complicated.

Given

Hannah spends $4.50 each day to buy lunch at her school.

After school each day, she buys the same snack.

Hannah spends $28.75 for lunch and snacks each week.

The equation and each day spend on snacks.

Let the school be open for 5 days a week.

and x be the snack.

5(x + 4.5) = 28.75 is the equation.

On simplifying, we get the value of x.

5(x + 4.5) = 28.75

   x + 4.5 = 5.75

            x = 1.25

Thus, the equation and each day spend on snacks are 5(x + 4.5) = 28.75 and 1.25.

what does it say young buck

Step-by-step explanation:

the lines segment joining two points on a curve.

Answer:

-1

Step-by-step explanation:

You can do this two ways, the easiest way is to look at the graph.

What is g(4) means: When the x value equals 4, what does y equal?

Look for the coordinate with the x-value of 4 (it's asking for g(4). Now if you look at the y-value of the coordinate, it should tell you what g(4) is. So since the coordinate is (4,-1), g(4) is -1.

Another way to do it is to plug in 4 for x in the equation. So...

g(4) = -[f(4) - 3)]

g(4) = -[4 - 3]

g(4) = -[1]

g(4) = -1

Answer:

ur missing a x in the equation

Answer:

x = 8

y = -8

Step-by-step explanation:

1. у = - 2х +8

2. - 7x - бу = - 8

Substitute y in equation 2 using equation 1

-7x - 6(-2x+8) = -8

-7x -(-12x) - 48 = - 8

Two negatives = positive

-7x + 12x - 48 = -8

5x - 48 = - 8

Plus 48 on both sides

5x = 40

Isolate x by dividing both sides by 5

x = 8

Using the value of x, find what y is.

y = -2(8) + 8

y = -16 + 8

y = -8

Hope this helps :)
