Answer:

23. x = 4; DE = 44

24. x = 25; DS = 28

Step-by-step explanation:

23. Point S is the midpoint of DE, so ...

DS = SE

3x +10 = 6x -2

12 = 3x . . . . . . . . . add 2-3x

4 = x . . . . . . . . . . . divide by 3

Then DS has length ...

DS = 3x +10 = 12 +10 = 22

and DE is twice that length, so ...

DE = 44

24. DS is half the length of DE, so is ...

DS = DE/2 = 56/2

DS = 28

Then x can be found from ...

DS = x +3

28 -3 = x = 25 . . . . . substitute value for DS

<em>Comment on problem 24</em>

Sometimes it is easier to work parts of a problem out of sequence. Here, finding DS first makes finding x easier.

Which of the following is a Pythagorean Triple?

Elena-2011 [213]

Answer: 3,4,5

Step-by-step explanation: a squared + b squared = c squared

A -> 3 squared is 9

B -> 4 squared is 16

9+16 is 25, so C has to be 25

C -> 5 squared is 25

So 3, 4, 5

Solve for w. | – w|≥2 Write a compound inequality like 1 < x < 3 or like x < 1 or x > 3. Use integers, proper fracti

Eduardwww [97]

Answer:

$-2 \geq w \geq 2$

Step-by-step explanation:

Given

$|-w| \geq 2$

Required

Solve for w

$|-w| \geq 2$

In absolution functions;

$|-w| = |w|$

So, the given expression can be rewritten as

$|w| \geq 2$

Removing the absolute sign, will gibe

$w \geq 2$ or $w \leq -2$

When the second inequality os rewritten, it gives

$w \geq 2$ or $-2 \geq w$

Reorder both inequalities

$-2 \geq w$ or $w \geq 2$

Lastly, both inequalities are combined

$-2 \geq w \geq 2$

Answer:

x-3

Step-by-step explanation:

f(x) = 3x - 2

g(x) = 2x + 1,

(f- g)(x) = 3x - 2 - ( 2x+1)

Distribute

= 3x -2 -2x-1

Combine like terms

x-3

Cathy has 16 meters of fencing to make a rectangular pen for some rabbits what dimensions will give the maximum area?

Travka [436]

The max occurs when length=width

so
perimiter=16
and L=W
P=2(L+W)
16=2(L+L)
16=2(2L)
16=4L
4=L

the dimentions are length and width are 4 meters
aera will be 16 square meters

Solve please!!<br> equation is in the directions!!

patriot [66]

14. The equation would be -16t^2+60t+7 To find the maximum point plug in values into the equation -b/2a to find the axis of symmetry, and plug that number in for t.
b=60, a=-16
-60/-32=t=1.875
-16(1.875)^2+60(1.875)+7=63.25
Maximum point: (1.875,63.25)
The ball will land after about 3.86 seconds
