8 0

Answer:

\sqrt{2} and 4\sqrt{11}

Step-by-step explanation:

To simplify like surds, add/ subtract the coefficients.

(a)

\sqrt{2} (6 - 5)

= \sqrt{2} (1)

= \sqrt{2}

(b)

\sqrt{11} ( 1 + 3)

= \sqrt{11} (4)

= 4\sqrt{11}

Which is the graph of the linear inequality 2x – 3y < 12?
lora16 [44]

On a coordinate plane, a dashed straight line has a positive slope and goes through (0, negative 4) and (3, negative 2) and to the left of the line is shaded.

<h3>What are the characteristics of the graph of the inequality?</h3>

Inequality of a graph is represented with the greater then(<), less then(>) or with the other inequity signs. The inequality line on the graph is represented with the dotted lines.

Characteristics of the graph of the inequality-

  • Open circle-When the value of the variable is equal to the given number, then the graph of the inequality has an open circle.
  • Closed circle-When the value of the variable is not equal to the given number, then the graph of the inequality has a closed circle.
  • The ray will move to the right-When the, value of the variable is greater than the number, then the ray will move to the right.
  • The ray will move to the left-When the value of the variable is less than the number, then the ray will move to the left.

The linear inequality given in the problem is,

2x - 3y < 12

The graph of this line is attached below. Here, for the greater than sign, every thing on the left of the graph is shaded, and the line will be dotted because of inequality as shown in the attached image.

Hence, on a coordinate plane, a dashed straight line has a positive slope and goes through (0, negative 4) and (3, negative 2) and to the left of the line is shaded.

7,080,267 written in expanded form
Alex787 [66]
If you know the definition of expand (to increase or make bigger)
then this will be easy.

when ever it asks for expanded for that means your answer has to be bigger than the number your given.

for your question:
 you have 7,080,267

so u first do the biggest value which is the first 7 on the left.
and then work your way down to the smallest which would be 7 on the right.

7000000
000000
80000
0000
200
60
7
that is the numbers expanded

but now u have to write it in the fom so you just add a + after each number

7000000+000000+80000+0000+200+60+7
you can shorten it by removing the numbers with no value:
7000000+80000+200+60+7

Answer:

just a random Teenage who's been through the same thing

Step-by-step explanation:

if you really care about what your mom think I'd suggest changing some thing's about you . maybe study more or something . if you don't usually try then go ahead try harder.

but if youre doing everything right but your cousin just seem to be better then you can't do much but try to explain to her that you're trying your best

stay safe and don't do anything you'd regret
