So first (3 1/2) equals to 3+1/2 which is 7/2, same for(2 1/3), 2+1/3=7/3. It's asking for speed in laps per minute, so like how many labs did she swim per minute, which is labs over time——(7/2)/(7/3)=(7/2)*(3/7)=3/2. So she swam 3/2 labs per minute.

The answer
let be 
A1 = (2x^4-3x^3+2x+4)-(-x^4-3x^3+4x^2+x+3) =
     = 2x^4-3x^3+2x+4 +x^4 +3x^3- 4x^2- x-3
A1= 6x^4 -2x² +x +1
and 
A2= 5x^4-2x^3+3x^2+3x-4-(2x^4-2x^3+7x^2+2x-5)
    = 5x^4-2x^3+3x^2+3x-4-2x^4+2x^3-7x^2-2x+5
A2<span>= 3x^4-4x²+x+1

A1 is not equivalent to A2
so the answer is </span><span>B. False </span>

PLEASE HELP ME WITH ALL ITS DUE TODAY!!
Vadim26 [7]

Answer:

Line 1 Slope: - 4/3

Line 2 Slope: 3/4

Line 3 Slope: 3/4

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

Line 1 and Line 2: Perpendicular

Line 1 and Line 3: Perpendicular

Line 2 and Line 3: Parallel

Step-by-step explanation:

Line 1: Passes through (6, -4) and (0, 4).

We first find the slope by using this equation (y2 - y1) / (x2 - x1) -    

(4 - (-4)) / (0 - 6)    

(4 + 4) / (-6)  

8 / -6

-4 / 3  

Slope = - 4/3

___________________________________________________________

Line 2: Passes through (-4, -2) and (8, 7).

We first find the slope by using this equation (y2 - y1) / (x2 - x1) -    

(7 - (-2)) / (8 - (-4))    

(7 + 2) / (12)  

9 / 12

3 / 4  

Slope = 3/4

___________________________________________________________

Line 3: Passes through (-4, -5) and (4, 1).

We first find the slope by using this equation (y2 - y1) / (x2 - x1) -    

(1 - (-5)) / (4 - (-4))    

(1 + 5) / (4 + 4)  

6 / 8

3 / 4  

Slope = 3/4

___________________________________________________________

Line 1 and Line 2: Perpendicular

Line 1 and Line 3: Perpendicular

Line 2 and Line 3: Parallel

What function? If correct ill give u the rest of 200 points please help
inessss [21]

Answer:

A function is an equation that has only one answer for y for every x. A function assigns exactly one output to each input of a specified type. It is common to name a function either f(x) or g(x) instead of y. f(2) means that we should find the value of our function when x equals 2.Step-by-step

■.Given angle TUV and ray UW, if m/TUV = 89,
aniked [119]

The measure of m<WUV is 53 degrees

<h3>Lines and angles</h3>

Given the following parameters

m<TUW = 22 +7x,

m<WUV = 41+ 6x

m<TUV. = 89

The related expression is given as:

m<TUV + m<WUV = m<TUV.

Substitute

22+7x+41+6x = 89

63 + 13x = 89

13x = 89 - 63

13x = 26

x = 2

Determine the measure of m<WUV

m<WUV = 41 + 6(2)

m<WUV = 41 + 12

m<WUV =53 degrees

Hence the measure of m<WUV is 53 degrees
