Answer:

Choice 3. -4x-3<13

Step-by-step explanation:

First, you will use process of elimination and cross out any obvious wrong answers. You can see that the symbol would not be flipped yet so the "<" would be pointing  to less than. That eliminates choice 1 and 4. Now, You can observe the 3rd step and see that -4x<16, to get that, you would need a "-4x" in the equation. Number 2 is 2x so that can't be right. Therefore, the answer is choice 3. This simple process of elimination and looking for clues will help you greatly in multiple choice problems instead of solving it the hard way.

Answer:

NO

YES

NO

YES

Step-by-step explanation:

for example :

(4³)³ = 4^9

4³.4³ = 4^6

I'll do part (a) to get you started. Part (b) will follow the same sort of steps.

In part (a), we have these two points

You can call the points any letters you want. Let's find the slope of line AB

m = (y2-y1)/(x2-x1)

m = (8-2)/(3-(-3))

m = (8-2)/(3+3)

m = 6/6

m = 1

The slope of line AB is 1.

The mirror line will have the negative reciprocal of this slope, so the slope of the mirror line is -1. In other words, the mirror line slope is perpendicular to line AB. We'll use this perpendicular slope later.

-------------------------------------------

Next, we find the midpoint of segment AB

Average the x coordinates to get (x1+x2)/2 = (-3+3)/2 = 0/2 = 0

Repeat for the y coordinates:  (y1+y2)/2 = (2+8)/2 = 10/2 = 5

The midpoint of AB is (0,5)

-------------------------------------------

The mirror line will have two defining traits

So,

y = mx+b

y = -1x+b ... plugging in that perpendicular slope

5 = -1*0+b .... plugging in (x,y) = (0,5)

5 = 0+b

b = 5

The equation of the mirror line is y = -x+5 as shown in the diagram below. The mirror line is shown in green. Point D isn't important as it's just used to help set up the 90 degree angle.

This wraps up part (a) and I'll let you handle part (b). If you're stuck, then feel free to ask.

Answer:

he have to travel 12 cm/km

Step-by-step explanation:

lets find x by transposing

3x = 2x + 2        (as M is the midpoint)

3x - 2x = 2

x = 2

now put 2 instead of x

3x + 2x +2 =  (distance from friends home to house)

3 (2) + 2 (2) +2

6 + 4 + 2

10 + 2

= 12

Answer:

Part A:

x^3 - 4x^2 - 29x -24

(x + 1)(x - 8)(x + 3)

Part B.

(x + 1)(x - 8)(x + 3) / x^2 - x - 2= (x + 3)(x - 8) / x - 2

g(x)=  (x + 3)(x - 8) / x - 2= y= x - 3

Answer:

13. Bestie literally 9+4

Answer:When solving a question like "What number is 4 less than 9?", take a close look at what it is really asking.

You have the number 9 and you are looking for a number that is 4 less than 9. In other words, if you have 9 and take away 4, then how many do you have?

You guessed it! This is a subtraction problem. 9 is the minuend and 4 is subtrahend and the answer we are looking for is the difference.

Therefore, to solve "What number is 4 less than 9?", you subtract 4 from 9 like so:

9 - 4 = 5

The answer is:

If you add 8x and 14x it will give you 22x

If you subtract 11-1 you have 10.

so the answer is 22x -10

[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]

Given, K is the midpoint of JL. So, JK = KL.

________

JL = JK + KL (given that K is the midpoint of JL)

JL = (8x + 11) + (14x - 1)

________

[tex] \large \boxed{\mathfrak{Steps} \downarrow}[/tex]

[tex] \sf( 8 x + 11 ) + ( 14 x - 1 )[/tex]

Combine 8x and 14x to get 22x.

[tex] \sf \: 22x+11-1 [/tex]

Subtract 1 from 11 to get 10.

[tex] \boxed{ \boxed{ \bf22x+10 }}[/tex]

________

Also given that, JK = KL.

So, (8x + 11) = (14x - 1)

⇨ (8x + 11) = (14x - 1)

⇨ 8x + 11 = 14x - 1

⇨ 11 + 1 = 14x - 8x

⇨ 12 = 6x

⇨ x = 12 / 6

⇨ [tex] \boxed{ \boxed{ \bf \: x= 2 }}[/tex]

________

Now, value of JL will be,

JL = 22x + 10

Substitute the value of x.

JL = 22(2) + 10

JL = 44 + 10

[tex] \boxed{ \boxed{ \bf\: JL = 50 }}[/tex]

⇨ So, the value of JL will be 50 units.
