Answer:

36 < n

Step-by-step explanation:

This means ANY value less than 36 will work

It's like completing an equation you + 11 on both sides which will leave you with n < 36

HELP AGAIN PLEASE I TRIED IT ON MY OWN AND FAILED :(

Alex787 [66]

Answer: ∠ J = 62° , ∠ K = 59° , ∠ L = 59°

Step-by-step explanation:

It is given that it is an Isosceles Triangle, where L J ≅ K J

It follows that ∠ K ≅ ∠ L

⇒ 5x + 24 = 4x + 31

⇒ x + 24 = 31

⇒ x = 7

Input the x-value into either equation to solve for ∠ K & ∠ L:

∠ K = 5x + 24

= 5(7) + 24

= 35 + 24

= 59

∠ K ≅ ∠ L ⇒ ∠ L = 59

Next, find the value of ∠ J:

∠ J + ∠ K + ∠ L = 180 Triangle Sum Theorem

∠ J + 59 + 59 = 180

∠ J + 118 = 180

∠ J = 62

Factorise 2x^2 - 3x -2 < 0

Galina-37 [17]

Step 1: Factor $2 x^{2} - 3x -2$
1. Multiply 2 by -2, which is -4.
2. Ask: Which two numbers add up to -3 and multiply to -4?
3. Answer: 1 and -4
4. Rewrite $-3x$ as the sum of $x$ and $-4x$

$2 x^{2} +x-4x-2\ \textless \ 0$

Step 2: Factor out common terms in the first two terms, then in the last two terms.

 $x(2x+1)-2(2x+1)\ \textless \ 0$

Step 3: Factor out the common term $2x+1$

$(2x+1)(x-2)\ \textless \ 0$

Step 4: Solve for $x$

1. Ask: When will $(2x+1)(x-2)$ equal zero?
2. Answer: When $2x + 1 = 0$ or $x-2=0$
3. Solve each of the 2 equations above:

 $x=- \frac{1}{2} ,2$

Step 5: From the values of $x$ above, we have these 3 intervals to test.
x = < -1/2
-1/2 < x < 2
x > 2

Step 6: Pick a test point for each interval

For the interval $x\ \textless \ - \frac{1}{2} 
$
Lets pick $x=-1.$ Then, $2(-1) ^{2} -3 * -1 -2 \ \textless \ 0$
After simplifying, we get $3\ \textless \ 0$ , Which is false.
Drop this interval.

For this interval $- \frac{1}{2} \ \textless \ x\ \textless \ 2$
Lets pick $x=0$ . Then, $2* 0^{2} - 3 * 0-2\ \textless \ 0$ . After simplifying, we get $-2\ \textless \ 0,$ which is true. Keep this interval.

For the interval $x\ \textgreater \ 2$

Lets pick $x = 3.$ Then, $2 * 3 ^{2} -3*3-2\ \textless \ 0.$ After simplifying, we get $7\ \textless \ 0$ , Which is false. Drop this interval.

.Step 7: Therefore,
$- \frac{1}{2} \ \textless \ x\ \textless \ 2$

Done! :)

Help! please I'm not sure what it is please i really need help for my final

AlladinOne [14]

Answer:A= 1,2 B=1,2 C=-9,10

Step-by-step explanation:

For A=

To find A', reflect the triangle exactly over the y-axis. That will put your A' at (1,2)

For B=

translate the triangle clockwise around the origin, (0,0), to put B' at (1,2)

For C= Translate point C to the left 4, and up 2, so the answer is (-9,10)

PLS HELP!!! Find the value of x in each figure and place the correct value into the box. Assume that the lines are parallel.

torisob [31]

Answer:

3x – 2 = 76 (Alternate Interior Angles)

3x = 76 + 2

3x = 78

x= 26°.

x + 2 = 40 (Alternate Interior angles).

x = 40 - 2

x= 38
