Answer:

your answer is (B) 5x-0.4

Step-by-step explanation:

The equivalent expression for the given function is -

y = 5x + 40.

A function is a relation between a dependent and independent variable. We can write the examples of functions as -

y = f(x) = ax + b

y = f(x, y, z) = ax + by + cz

Given is the expression -

5(x + 8)

We can write the equivalent expression for the given function is -

y = 5(x + 8)

y = 5x + 40

Therefore, the equivalent expression for the given function is -

y = 5x + 40.

The equation of the described circle is:

(x - 2)² + y² = 234

Remember that the equation for a circle whose center is (a, b) and has a radius R, is:

(x - a)² + (y - b)² = R²

Here the endpoints of the diameter are (17,-3) and (-13, 3), then the center is at:

( [17 - 13]/2, (-3 + 3)/2)

(2, 0)

And the radius is the distance between the center and any of these points:

R = √( (2 - 17)² + (0 + 3)²)

R = √234

Then the equation is:

(x - 2)² + (y - 0)² = √234²

(x - 2)² + y² = 234

Answer B 11m

Step-by-step explanation:

Answer:

29 books ; 5 bookshelfs

Step-by-step explanation:

Solving logically ;

Prime numbers between 21 and 30 = 23, 29

Hence, number of books Fernando has is either 23 or 29

Taking 4 away from the number of books, he'll be able to arrange same number of books on each of his book shelve;

From the statement, we can conclude that :

Subtracting 4 from the number of books Fernando has should give a perfect square

If 23 books

23 - 4 = 19 ; 19 isn't a perfect square

If 29 books :

29 - 4 = 25

Hence, to place the same Number of books on each shelf :

Sqrt(25) = 5

Hence, number of bookshelf = 5

Answer:

If your trying to answer for X, here is how you do it.

For the equation '' Y = 10x + 20 '', isolate the variable 'X' by dividing each side by factors that don't contain the variable 'X', to get your answer:

X =  Y/10 − 2

Or

X = [tex]\frac{Y}{10}[/tex] − 2

For the other equation " Y = 20x + 10 ", it's the exact same thing. Isolate the variable 'X' by dividing each side by factors that don't contain the variable 'X', to get your answer:

X = Y/20 − 1/2

Or

X = [tex]\frac{Y}{20}[/tex] − [tex]\frac{1}{2}[/tex]

Answer:

Yes; there is only one range value for each domain value.

Step-by-step explanation:

For a relation to be a function, every input, x-value, needs to have a unique output, y-value. This means that one x-value cannot have multiple y-values. So, in a function x-values will never repeat. Since x-values do not repeat in this relation, it is a function.

Angle sum property of triangle states that the sum of interior angles of a triangle is 180°

We need to prove angle sum property.

What is angle sum property?

The sum of interior angles of a triangle is 180 degrees

Consider a ∆ABC, as shown in the figure below. To prove the above property of triangles, draw a line PQ parallel to the side BC of the given triangle

Since PQ is a straight line, it can be concluded that:

∠PAB + ∠BAC + ∠QAC = 180°  ………(1)

Since PQ||BC and AB, AC are transversals,

Therefore, ∠QAC = ∠ACB (a pair of alternate angle)

Also, ∠PAB = ∠CBA (a pair of alternate angle)

Substituting the value of ∠QAC and ∠PAB in equation (1),

∠ACB + ∠BAC + ∠CBA= 180°

Thus, the sum of the interior angles of a triangle is 180°.

Answer: 45

Step-by-step explanation:

3(-2m + 5) -6(-4m - 2) =

-6m + 15 + 24m + 12=

18m + 27

18= a 27= b 27 + 18= 45

The value of the expression a + b is 45.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

First, we can simplify the expression using the distributive property:

3(-2m + 5) - 6(-4m - 2) = -6m + 15 + 24m + 12

Combining like terms, we get:

18m + 27

So, a = 18 and b = 27, which means:

a + b = 18 + 27 = 45

Therefore,

The value of a + b is 45.
