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:

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

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.

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.

The value of  x from the expression is 2

Given the expression

2x = 74/2 - 37

We are to calculate the value of  x from the expression

2x = 37 - 37

Since 37 - 37 = 0

2x = 0

Divide both sides by 2:

2x/2 = 0/2

x = 0

Step-by-step explanation:

Let [tex]x[/tex] = the number of problems Anna completed

Using ratios

                                      5 : 8 = [tex]x[/tex] : 32

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:

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)

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.

Answer:

7295

Step-by-step explanation:

The first thing we can do is rule out any numbers that cannot be divided by 5. Any number that ends in a 0 or a 5 can, so 627 cannot be. The next thing we do is use the division rule for dividing by 3. The rule states that if you add up the digits of a number, and it is divisible by 3, then so is that number.

2+8+5= 15 (multiple of 3)

5+4+9+0=18 (multiple of 3)

7+2+9+5=23 (not a multiple of 3)

4+3+6+9+5=27 (multiple of 3)

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 :)

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]

The result of John's multiplication in standard form is

3.12 × 10⁹

To express the result in standard form, we need to represent it as a number between 1 and 10 (inclusive) multiplied by a power of 10.

In other words, the number should have the form:

a × 10ⁿ

where "a" is a decimal number greater than or equal to 1 and less than 10, and "n" is an integer representing the power of 10.

Let's calculate the result of John's multiplication:

= 400,000 × 7,800

= 3,120,000,000

Now, we need to convert this number into standard form. To do that, we will move the decimal point to the left until there is only one non-zero digit to the left of the decimal point.

The number of places we move the decimal point will give us the power of 10.

In this case, we will move the decimal point three places to the left:

3.120000000 × 10⁹

Now, we can simplify the number by removing trailing zeros:

3.12 × 10⁹

So, the result of John's multiplication in standard form is

3.12 × 10⁹

Step-by-step explanation:

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

So 100 x 0.5 = 50

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
