I just learned about this!

How to get Number 1: This closed circle represents it is more than or equal to 4. so it should be x ≥ 4.

How to get number 2: This circle is open which means it is NOT equal to or close to the number so it should be x≠-4. Because you don't know how much x is and the lines and arrows represent it is not equal.

Number 3: The first option is the correct one as it says clearly x is less than -3 so it should be a open circle.

Number 4: The 2nd one is right because x is less than -1 or equal to -1.

MatroZZZ [7]
<span>(x, y)→(x − 8, y − 7) is the correct translation. Take point D for example. The coordinate of D is (2, 5). The coordinate of D' (after translation) is (-6, -2). Since 2-8=-6, 5-7=-2, only the first choice is correct. You can also try other points and see why only this is the right translation.</span>

Yanira is 3 years older than tim and twice as old as hannah. tim is 2 years older than hannah. how old are yanira, tim, and hann
Sati [7]
Y = T+3 (i)
T = H+2  (ii)
Y = 2*H  (iiii)

T = H+2  therefore H = T-2

Substitute H=T-2 into (iii)
Y=2*H
Y=2*(T-2)
Y=2T-4

Now substitute that Y into (i)
(i) says Y = T+3
2T-4=T+3
2T-T-4=3
T-4=3
T=3+4
T=7

Then from (i) Y=T+3 = 7+3 =10
Y=10

And from (iii) Y=2*H
If Y = 10, then H = 5

2/3 + 1/2 in simple form fractions
nata0808 [166]
Try and find the common denominator which is 6 since 2×3 is 6 then once u get ur denominator u have to find the numerator which would be 4/6+3/6 And that would equal 7/6 and if you would u would keep it like that but if u would have to change it into a mixed fraction it would be 1 and 1/6

Hoped this helped
