PLZZ CAN SOMEONE CHECK MY ANSWERS !!!

Mathematics
1 answer:
larisa86 [58]3 years ago
8 0

Answer:

(1,0)

(5,24)

(-2,3)

Step-by-step explanation:

So we want y=x^2-1 per point.

Let's check them.

(0,1)? Plug in 0 for x and see what y is:

y=0^2-1

y=0-1

y=-1 which is not 1.

(1,0)? Plug in 1 for x and see what y is:

y=1^2-1

y=1-1

y=0 which is what we have for y.

(3,5)? Plug in 3 for x and see what y is:

y=3^2-1

y=9-1

y=8 which is not 5.

(5,24)? Plug in 5 for x and see what y is:

y=5^2-1

y=25-1

y=24 which is what we have for y.

(-2,3)? Plug in -2 for x and see what y is:

y=(-2)^2-1

y=4-1

y=3 which is what y is.

(-4,-17)? Plug in -4 for x and see what y is:

y=(-4)^2-1

y=16-1

y=15 which is not -17.

Express -32/243 into power notation​
lesya692 [45]

This problem can take a while if you cannot observer the answer quickly.

First of all we can see that 32=2*2*2*2*2=2^5

243, if you don't know its actually is 3^5

Now we can see that this turns into...

- 2^5/3^5

since the 5th power doesn't change the sign of the original number, we can put the negative in the ( ), if you don't know what I mean look below

(-3)^2=9 Positive

(-3)^3=-27 Negative since its to the odd power it keeps the sign.

This problem can be simplified to.

(-2/3)^5

And this is the answer :D

If you have any questions just put them in the comments.

AB is a midsegment of trapezoid DEFG what is x?
Mamont248 [21]

Answer:

D. 2

Step-by-step explanation:

DEFG is a trapezoid and AB is its Midsegment.

Therefore,

AB =\frac{1}{2}(DG + EF)  \\  \\ 12 =  \frac{1}{2} (5x - 4 + 8x + 2) \\  \\ 12  \times 2= (13x - 2) \\  \\ 24 = 13x - 2 \\  \\ 24 + 2 = 13x \\  \\ 26 = 13x \\  \\ x =  \frac{26}{13}  \\  \\ x = 2
