Evaluate 4(2a – b) when a = –1 and b = 5.

grin007 [14]

Hey There!

<h2>Question:-</h2>

$\sf \longmapsto \: 4(2a - b)$

This is a algebraic expression. The values of a and b are given. The values are as follows :-

a = -1

And,

b = +5 .

<h2>Solution:-</h2>

$\sf \longmapsto4(2a - b)$

Note that a is multiplied with 2 that is :-

$\sf \longmapsto4(2 \times a \: - b)$

Now, Insert the values that is a = -1 and b = 5 :-

$\sf \longmapsto4(2 \times - 1 - 5)$

Here,we need to follow BODMAS Rule.

B = Brackets

O = Orders

D = Division

M = Multiplication

A = Addition

S = Subtraction

We need to solve the bracket's calculations first as it is the rule.

So, Firstly Multiply (2 × -1) :-

$\sf \longmapsto4( - 2 - 5)$

Note that, (-) × (-) equals to (+).

So, it will be 5+2,But as 5 is bigger number than 2, 5 contains a minus sign.So the result will be -7.

$\sf \longmapsto4( 5+ 2)$

On Simplification:-

$\sf \longmapsto4( - 7)$

$\sf \longmapsto4 \times (- 7)$

$\sf \longmapsto \: - 28$

______________________________________

Henceforth the solution of the algebraic expression is :-

$\bf \:- 28$

Option B is correct!

I hope this helps!

Please let me know if you have any questions.

lukranit [14]

To solve this you just do ehat was done to the coordinates. So x goes from x to 4x do you are mutiplying by 4. and the same goes for y. so your scale factor is 4

2 times 4 is 8 and 1 times 4 is four

A(8,4)

4 times 4 is 16 and 1 times four is four

B(16,4)

Four times four is sixteen and negitive three times four is negitive 12

C(16,-12)

Given the options the answer will be B.

What are the domain and range

natta225 [31]

For this case, the first thing we must do is observe that the graph has two asymptotes.

A horizontal asymptote or equivalently:

$y = 0$

A vertical asymptote or equivalently:

$x = 0$

Therefore, the domain and the range of the function is the same:

All reals excluding zero.

Answer:

The domain and range is the mime:

All reals excluding zero.

galben [10]

Answer:

4 to 1

Step-by-step explanation:

The greatest common factor between 8 and 2 is 2. So 2 will go into 8, 4 times. And 2 will go into 2, 1 time. So simplified the equivalent ratio is 4:1.
