Answer:

A) 2 5/12

Step-by-step explanation:

The word <u>MORE </u>refers to subtraction. If you know how to calculate fractions. Great! You should know what 2 3/4 - 1/3 equals. But if you do not:

You can use a regular calculator. Just convert everything to decimals. ( "/" means divide)

3/4 (3÷4) = 0.75 (dont forget the 2 since is has 2 3/4) so 2.75.

1/3 (1÷3) = 0.33<u>3 </u>(underline or overline (above the number) means that number repeats. if you are using a calculator. just max the numbers out till you can put it anymore.

2.75 - 0.<u>3</u> = 2.41<u>6</u>. Now you dont know what that 416 is so just subtract the answers until it matches.

B) 1 ÷ 12 = 0.8<u>3. </u> well it isnt 416 so that isnt right.

4 ÷ 7 = 0.571... (... means a bunch of numbers that go on and on.) again that isnt correct. Now lets try A):

5 ÷ 12 = 0.41<u>6</u>!

Hope this helps!

Which system of equations below has infinitely many solutions? y = –3x 4 and y = –3x – 4 y = –3x 4 and 3y = –9x 12 y = –3x 4 and
Flura [38]

the equations y = –3x + 4 and 3y = –9x + 12 have infinitely many solutions. option B is correct.

<h3>What is the linear system?</h3>

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

Condition for the parallel lines.

L1,  ax + bx + c = 0

L2, dx + ey + f = 0

If \rm \dfrac{a}{d} = \dfrac{b}{e} = \dfrac{c}{f} then lines have infinitely many solutions.

<h3>Which system of equations below has infinitely many solutions?</h3>

y = –3x + 4 and 3y = –9x + 12

On comparing we have

a = -3 , b = 1, and c = 4

d = -9 , e = 3, and f = 12

Then their ratio will be

\rm \dfrac{1}{3} = \dfrac{-3}{-9} = \dfrac{4}{12}\\\\\rm \dfrac{1}{3} = \dfrac{1}{3} = \dfrac{1}{3}

Hence  y = –3x + 4 and 3y = –9x + 12 have infinitely many solutions.

Thus the option B is correct.

BRAINLIEST MATH okurttttt
Zepler [3.9K]

In the given question, \sqrt{x-1}is shifted one unit to the right of \sqrt{x}

So, Option C is correct.

Step-by-step explanation:

The parent function is \sqrt{x} and transformed function is \sqrt{x-1}

So, Parent Function: \sqrt{x}

Transformed Function: \sqrt{x-1}

  • If transformed function is of type: g(x) = f(x-h), then the graph is shifted to right h units.

So, In the given question, \sqrt{x-1}is shifted one unit to the right of \sqrt{x}

So, Option C is correct.
