Answer:C

Step-by-step explanation:

I pretty sure it would be C because if coordinate A moves to (1,4) the whole shape moves so Coordinate A move one back so -1 and up two so +2 so im pretty sure it is C.

Which of the following is the solution set of the equation

svet-max [94.6K]

Which of the following is the solution set of the equation
10(x^2+1/x^20)-63(x-1/x)=52=0
I think you type wrongly the equation:
It is : 10(x^2+1/x^2)-63(x-1/x)+52=0
We know: x²+1/x²=(x-1/x)²+2, pose x-1/x=t and we have x²+1/x²=t²+2
So 10(t²+2)-63t+52=0
or 10t²-63t+72=0
we have t=(63+33):20= 24/5
and t=(63-33):20=3/2

+ If t=3/2 we have x-1/x=3/2 or 2x²-3x-2=0 and we have x=2, x=-1/2
+ Of t=24/5 we have x-1/x=24/5 or 5x²-24x-5=0 or x=5 and x=-1/5

And the answer: c) (5,2,-1/5,-1/2)

Simplify the exponential expression.

Sever21 [200]

Answer:

Step-by-step explanation:

Well you could use the exponential identity that: $\frac{x^a}{x^b}=x^{a-b}$

To determine: $\frac{h^3}{h^3}=h^{3-3}$

Which means that it's equal to: $h^0$

and since anything to the power of 0 (except 0) is equal to 1, then the value is 1.

But you can also just see that the numerator and denominator are the same exact value, and since dividing something by it self, results in 1, the answer must be 1, which is kind of a proof as to why h^0 = 1.

Omg pls help ill give you 20 points

ElenaW [278]

Answer:

Step-by-step explanation:

Amount of water in tank 1 = amount of water in tank 2

30t +25 = -20t + 1000

Add 20t to both sides

30t + 20t + 25 = -20t + 20t + 1000

50t + 25 = 1000

Subtract 25 from both sides

50t + 25 - 25 = 1000 - 25

50t = 975

Divide both sides by 50

t = 975/50 = 39/2

$= 19 \frac{1}2}$

t = 19 minutes 30 seconds

After 19 1/2 minutes both tanks will have 610 liters of water

How do I find the value of y?

Genrish500 [490]

Answer:

y = 27

Step-by-step explanation:

line segment BA and CD are congruent, turn them into an equation

3y - 59 = y - 5

subtract 1y from both sides, you get 2y - 59 = -5

then, add 59 to both sides and the equation is now 2y = 54

divide each side by 2 and you get the value of y (y = 27)
