Step-by-step explanation:

combine like denominators:

(1-x^4)/(x^2+1)+(x^4-1)/(x^2-1)

factor:

(1-x^2)(1+x^2)/(x^2+1)+(x^2+1)(x^2-1)/(x^2-1)

reduce:

(1-x^2)+(x^2+1)

Answer:

Bill gave Ann £220

Step-by-step explanation:

plz mark brainliest :D

Ann shared £360 and Bill shared £80.

A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.

Given:

Ann and bill shared £440

Ratio = 9:2

Total is = 9+ 2= 11

So, Anna shred

= 9/11 x 440

= 360

and Bill shred

= 2/11 x 440

= 80

Answer:

Now how did I get the translation rule (x + 1, y + 3). Well basically, I did this :-

-4 - (-5) = 1

12 - 9 = 3

Now let us plug it in the translation rule to see if I get (-4, 12).

(x + 1, y + 3)

(-5 + 1, 9 + 3)

(-4, 12)

I get the same answer given in the problem. Hope this helps, thank you !!

Answer:

i really dont know

Step-by-step explanation:

The unit rate when y should be equivalent to 6x should be considered as the 1:6.

Since the equation be y = 6x

So, it can be like

y = 1 :6

Hence, we can conclude that The unit rate when y should be equivalent to 6x should be considered as the 1:6.

Answer:

w = 15

Step-by-step explanation:

We have an expression and are asked to solve for w.

-19w + 11 = -17w - 19

Subtract 11 from both sides :

-19w = -17w - 30

Add 17w to both sides :

-2w = -30

Divide -2 from both sides to isolate w :

w = 15

if you want to find the symmetry, you have to divide the total number with 2. So if there 8 petal divide by 2 and there are 4 lines of symmetry

Answer:

Step-by-step explanation:

The coefficient of a variable is always the number before the variable, if there is no number before a variable the coefficient is always 1.

In this case, since the subtraction sign is before the variable, you will need to make the variable positive by making the coefficient of variable y, -1.

In short terms, your answer is -1. :)

Answer: y=5x+7

Step-by-step explanation:

If you draw a graph or use a graphing calculator the points and then connect them you will see that the y-intercept is 7 and the slope is 5/1. Slope intercpt  form is y=mx+b. So the equation is y=5x+7.

Answer:

let (x1,y1)=(1, 2)

and(x2,y2)=(3,-8)

Step-by-step explanation:

we have

y-y1=(y2-y1)(x-x1)/(x2-x1)

y-2=(-8-2)(x-1)/(3-1)

y-2=-10(x-1)/2

y-2=-5(x-1)

y-2=-5x--5

y+5x=5+2

note :-×-=+

Answer: add 1

Step-by-step explanation:

Answer:

y=-2/3x-1

Step-by-step explanation:

You can fins the slope (or the m in y=mx+b) by counting how many units up/down and over it takes to get to another solid point and configuring it into a fraction rise/run. in this case you go down 2 units and over 3 units to get -2/3

to get the y-intercept (the b in y=mx+b) you look at where the lince intercepts the y-axis in this case it is at -1

Answer:

5.20

Step-by-step explanation:

100%-15%=85%

85%->4.42

100%->4.2÷85×100=5.20

Answer:

Step-by-step explanation:

From laws of indices, we know that;

a^(x) × a^(y) = a^(x + y)

Similarly, in our question, 4 • 4^(x) implies that; 4¹ × 4^(x)

Since 4 can be also expressed as 4¹.

Thus,this equals; 4^(x + 1)

This expression is same as the other one given in the question as 4^(x + 1).

Thus, 4 • 4^(x) is the same as 4^(x + 1).

This my answer thanks

The equation that can be entered into a graphing calculator to solve 16.9x–2.3=3.2x+18 are y = 16.9x - 2.3 and y = 3.2x + 18 respectively. Option B is correct.

The equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.

The equation is

16.9x - 2.3 = 3.2x + 18

From options
y = 16.9x - 2.3 and y = 3.2x + 18

Hence, the equation that can be entered into a graphing calculator to solve 16.9x–2.3=3.2x+18 are y = 16.9x - 2.3 and y = 3.2x + 18 respectively.
