Answer:

x = -4, 4

Step-by-step explanation:

Hi there!

[tex]x^2-16=0[/tex]

Rewrite 16:

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

The difference of squares rule states that [tex]a^2-b^2=(a+b)(a-b)[/tex]. With this, apply the difference of squares to the equation:

[tex](x+4)(x-4)=0[/tex]

The zero-product property states that if the product of two numbers is 0, then one of the numbers must be equal to zero. Set each term equal to 0 and find the solutions:

[tex]x+4=0\\x=-4[/tex]

[tex]x-4=0\\x=4[/tex]

Therefore, the solutions are -4 and 4.

I hope this helps!

Answer:

362

Step-by-step explanation:

Let the ones digit equal x. If the ones digit is one, then the hundreds digit is one more than it or x + 1. And, since the tens digit is twice the hundreds digit, you can say it is 2(x + 1) or as simplified: 2x + 2. Now, we are given the sum of the digits is 11, so if we add all of them, they should be equal to 11:

x + x + 1 + 2x + 2 = 11

We can combine like terms:

4x + 3 = 11

4x = 8

x = 2

So, the ones digit is 2. Since the hundreds digit is one more, it's 3. And because the tens is twice the hundreds, it's 6. The number is 362.

Answer:

Answer:

42.39 ft²

Step-by-step explanation:

area of sector= 3/8 × 3.14 × 6²

= 42.39 ft²

The area of the sector is 42.39 ft²

Given that, a sector of a circle has a diameter of 12 feet and an angle of 3pi/4 radians, we need to find the area of the sector,

Area of the sector = θ/360° / π·radius²

area of sector= 3/8 × 3.14 × 6²

= 42.39 ft²

Hence, the  area of the sector is 42.39 ft²

The function operation (f/g)(x) in the functions f(x) = 10x-15 and g(x) =2x-3 is 5.

A function is simply a relationship that maps one input to one output.

Given that;

First, we replace the function designators in f/g with the actual functions.

(f / g )(x) = f(x) / g(x)

(f / g )(x) = ( 10x - 15 ) / ( 2x - 3 )

Now, factor out 5 from 10x and -15

(f / g )(x) = 5( 2x - 3 ) / ( 2x - 3 )

Cancel the common factor of 2x - 3

(f / g )(x) = 5( 1 ) / ( 1 )

(f / g )(x) = 5 / 1

(f / g )(x) = 5

Therefore, the function operation (f/g)(x) equals 5.

Step-by-step explanation:

By question , it's given that the X intercept is (5,0) and the y intercept is (0,8) . And we need to find the y-intercept of the graph of f(x) + 3 . For that , firstly let's find out the equation of the line.

[tex]\sf\implies y- y_1 = \bigg(\dfrac{y_2-y_1}{x_2-x_1}\bigg) ( x - x_1) \\\\\sf\implies y - 0 = \bigg(\dfrac{0-8}{5-0}\bigg)( x - 5 ) \\\\\sf\implies y = \dfrac{-8}{5}( x - 5 ) \\\\\sf\implies 5y = -8x +40 \\\\\sf\implies 8x + 5y - 40 = 0 [/tex]

Let us say that this is f(x) :-

[tex]\\\\\sf\implies f(x) = 8x + 5y - 40 \\\\\sf\implies \boxed{\sf\red{ f(x)+3 = 8x +5y -37 }}[/tex]

Plot its graph :-

We can either convert it into intercept form but plotting a graph can also be done to find y intercept .

[tex]\implies \boxed{\pink{\sf y - intercept = 7.4}}[/tex]

Refer to attachment for graph .

Hence the y Intercept is 7.4 .

will you help me with grade 9 math, algebra 2 please

Step-by-step explanation:

range{-2,00)

Step-by-step explanation:

In the graph the domain is {-3, -1, 0, 1, 2} and range is {-2, 1}

A relation is a function if it has only One y-value for each x-value.

The domain and range are defined for a relation and they are the sets of all the x-coordinates and all the y-coordinates of ordered pairs respectively.

If the relation is, R = {(2, 1), (1, 1), (0, 1), (-1, -2), (-3, -2)}, then:

Domain = the set of all x-coordinates = {-3, -1, 0, 1, 2}

Range = the set of all y-coordinates = {-2, 1}

Answer:

d=2

Step-by-step explanation:

8(d+2)-36=2+6(1-d)

Expand the equation

8d+16-36=2+6-6d

Put like terms together

8d+6d = 2+6-16+36

14d= 28

Divide 14 on both sides to get the value of d

[tex] \frac{14d}{14} = \frac{28}{14} [/tex]

d=2

Answer:

17

Step-by-step explanation:

Use the distance formula to determine the distance between the two points.

[tex]d = \sqrt{(x_{2} -x_{1})^{2} + (y_{2} - x_{1})^{2} }[/tex]

d = distance

[tex](x_{1}, y_{1})[/tex] = coordinates of the first point

[tex](x_{2}, y_{2})[/tex] = coordinates of the second point

Answer: The distance between the points (6,-7)(-2,8) is 17.

Step-by-step explanation:

To calculate the distance between two points, we apply the following formula:

[tex]\boldsymbol{\sf{d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2 } }}[/tex]

The points are:

We substitute in the formula and solve:

[tex]\boldsymbol{\sf{d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2 } }}\\ \\ \boldsymbol{\sf{d=\sqrt{(-2-6)^2+(8-(-7))^2 } }}\\ \\ \boldsymbol{\sf{d=\sqrt{(-8)^2+15^2}=\sqrt{64+225 } }}\\ \\ \boldsymbol{\sf{d=\sqrt{289}=17 }}[/tex]

The distance between the points (6,-7)(-2,8) is 17.
