Answer:

C

Step-by-step explanation:

Divide the numerator but the denominator to get a decimal. (That tip saved me in 6th grade)

Answer:

2

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)

1+1=2

Answer:

32.8m

Step-by-step explanation:

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).

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

Answer:

cylinder: v= 6616.19

cone: v=4539.6

Step-by-step explanation:

cylinder: π r²h

pi= 3.14

radius/r=9

height/h=29

29* 9² * π= 6616.19

cone: π r² [tex]\frac{h}{3}[/tex]

pi= 3.14

radius/r=17

height/h=15

π * 17² * 15=4539.6

hope this helps :) have a nice day !!

Answer:

its C it has 4

Step-by-step explanation:

Answer:

C 4

Step-by-step explanation:

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:

i think it is b but i am not 100%

sorry if i am wrong

Step-by-step explanation:

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:

AD=16

AB=20

Step-by-step explanation:

BD=12

9/DB=DB/AD=9/12=12/AD

9AD=144

AD=16

AB^2=25^2-15^2

AB^2=400

AB=20

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

Answer:

n = the number

3n = three times the number

3n - 11 = three times the number decreased by eleven

Answer:

3

Step-by-step explanation:

(8y-3)+(-8y+6)=

8y + -8y = 0

-3 + 6 = 3

0 + 3 = 3

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:

5.20

Step-by-step explanation:

100%-15%=85%

85%->4.42

100%->4.2÷85×100=5.20

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:

The answer is x = -4 ± √34 /3

Step-by-step explanation:

Solve the equation for  x  by finding  a ,  b , and  c  of the quadratic then applying the quadratic formula.

Hoped this helped!

Answer:

x = 0 and y = -2

Step-by-step explanation:

x - 2y = 4 and X - 1y = 2

you mentioned elemination aka substraction

so you when substract x - x =  0  -2y -( -y) = -y and 4 -2 = 2

so - y = 2

or y = 2

now substitute the numbers

x + 4 = 4

x = 0

and try it with one of the equation  or sometimes trying on both of them can be very helpful

Answer:

81m+27t

Step-by-step explanation:

Answer:

81m + 27 t

Step-by-step explanation:

Answer:

$20.24

Step-by-step explanation:

Since the 25% discount takes off a quarter of the price, we multiply 24.99 by 3/4

24.99 x 3/4 = 18.74

So with the discount and without tax, the cost of the jacket is 18.74

Then we add 8% for sales tax

8% of 18.74 is $1.50

18.74 + 1.5 = 20.24

So the final cost of the jacket is $20.24
