Given g(x)=8x+3 find the following g(-1) and g(2a+1)

Mathematics
1 answer:
Degger [83]2 years ago
4 0

Answer:

g(-1) = -5

g(2a+1) = 16a+11

Step-by-step explanation:

Substitute the given value into the function and evaluate.

So for g(x) = 8x+3

You substitute g(-1)

So g(-1) = 8(-1)+3

That is how you get -5

Then g(2a+1)

So g(2a+1) = 8(2a+1)+3

Thats how you get 16a+11

In the number 7,777. 777, what is the difference between the 7 in the hundreds place and the 7 in the column to its left?.
oksano4ka [1.4K]

The decimal point 7 in the integer 0.07 corresponds to the fraction 7/100. Every position in the decimal system corresponds to a power of 10.

<h3>What is unitary method?</h3>

Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape.

On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a shape on paper is the area that it occupies.

Consider your square as being composed of smaller unit squares.

The number of unit squares necessary to completely cover the surface area of a specific 2-D shape is used to calculate the area of a figure. Some typical units for measuring area are square cms, square feet, square inches, square meters, etc.

Draw unit squares with 1-centimeter sides in order to calculate the area of the square figures shown below. The shape will therefore be measured.

hence, The decimal point 7 in the integer 0.07 corresponds to the fraction 7/100. Every position in the decimal system corresponds to a power of 10.

What is the vertex of the quadratic function f(x)=(x-8)(x-2)?
maw [93]

Answer:

(5, -9)

Step-by-step explanation:

f(x)=(x-8)(x-2)

We want the vertex.  So let us get this in Vertex Form.

f(x)  =  (x - 8)(x - 2) =  x^2 + 16 - 10x

f(x) = x^2 - 10x + 16

f(x) = x^2 -10x  + 25  - 25 + 16

f(x) = (x^2 -10x  + 25)  - 25 + 16

f(x) = (x - 5)^2 - 9

Vertex at  (5, -9)

(3x+15) (6x+3) m&lt;1 is
Allisa [31]

Answer:

x = 4

Step-by-step explanation:

Simplifying

3x + 15 = 6x + 3

Reorder the terms:

15 + 3x = 6x + 3

Reorder the terms:

15 + 3x = 3 + 6x

Solving

15 + 3x = 3 + 6x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-6x' to each side of the equation.

15 + 3x + -6x = 3 + 6x + -6x

Combine like terms: 3x + -6x = -3x

15 + -3x = 3 + 6x + -6x

Combine like terms: 6x + -6x = 0

15 + -3x = 3 + 0

15 + -3x = 3

Add '-15' to each side of the equation.

15 + -15 + -3x = 3 + -15

Combine like terms: 15 + -15 = 0

0 + -3x = 3 + -15

-3x = 3 + -15

Combine like terms: 3 + -15 = -12

-3x = -12

Divide each side by '-3'.

x = 4

Simplifying

x = 4
