Answer: 50

Step-by-step explanation:

exterior angles are supplement of interior angle therefore the 110 thing must be 70, also youre given 60 so 70+60=130

50 is missing from 180

Answer:

2y = 12 is a function

Step-by-step explanation:

In the graph of a function, the value of the x-value in an ordered pair can not be use only once.  The graph in the other problems shows that the same x-value was used more than one time.

Answer:

x^2+3=h

to make x the subject of the formula,move 3 to the other side making it negative

x^2 = h + 3

to take out the square,take the square root of both sides.

√x^2 = √ h + 3

x = √ h + 3.

Answer:

D=4

Step-by-step explanation:

a. The solution of the equation x + 2 = √3x + 10 is x = -3 or x =2.

b. Extraneous solution is x= -3.

c. Extraneous solution does not satisfy original equation.

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.

As given in the question,

Given equation :

x + 2 = √3x + 10

a. Squaring both the sides

( x + 2 )² = ( √3x + 10 )²

⇒ x² + 4x + 4 = 3x + 10

⇒ x² + x - 6 =0

⇒ x² + 3x -2x -6 =0

⇒ ( x+ 3) ( x -2) =0

⇒ x= -3 or x = 2

b. Extraneous solution:

x = -3

-3 + 2 = √3(-3)+ 10

⇒ -1  ≠ 1 extraneous solution.

x= 2

2+ 2 =√3(2) +10

⇒4 = 4 not extraneous.

c. Extraneous solution does not satisfy original equation

Therefore, the solution of the equation is x = -3 or x=2and its extraneous solution is x =-3. Extraneous solution does not satisfy original equation.

The solution is (2,-2)

Step-by-step explanation:

Answer:

false

Step-by-step explanation:

it would be subtracting 6 units

Answer:

Well you got 1/4 + 1/12

So we have to have the same denominator in order to solve this

So by finding a common multiple, you would be able to solve this

So in this case is the common multiple.

we already have a 12 so we leave that be.

We need to convert 1/4 to x/12

To Do that we multiplying it by 3

so 3/12 + 1/12

Now add normally and keep the denominator

4/12

or 1/3

Answer:

Time taken by the person to walk the boardwalk to the end and back is 0.9 hours.

Given that, The Coney Island Boardwalk is 2.7 miles long.

The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.

A person walks at the average speed of 3 mph.

We know that, speed = Distance/Time

= 2.7/3

= 0.9 hours

Hence, time taken by the person to walk the boardwalk to the end and back is 0.9 hours.

Step-by-step explanation:

The solution of the expression (- 3 - x) (x + 42) (x - 16) will be;

⇒ - x³ - 29x² + 564x + 2,496

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ (- 3 - x) (x + 42) (x - 16)

Now,

Solve the expression as,

⇒ (- 3 - x) (x + 42) (x - 16)

⇒ (- 3x - 156 - x² - 42x) (x - 16)

⇒ (- x² - 45x - 156) (x - 16)

⇒ - x³ + 16x² - 45x² + 720x - 156x + 2,496

⇒ - x³ - 29x² + 564x + 2,496

Thus, The solution of the expression (- 3 - x) (x + 42) (x - 16) will be;

⇒ - x³ - 29x² + 564x + 2,496
