Complete the table thanks in advance

Y = 1/2 x

for x = 0 → y = 1/2 · 0 = 0
for x = 2 → y = 1/2 · 2 = 1


   x      | 0 | 2 |
y=1/2x| 0 | 1 |


y = x + 3

for x = 0 → y = 0 + 3 = 3
for x = -3 → y = -3 + 3 = 0

    x    | 0 | 3 |
y=x+3|-3 | 0 |

The answer is C, but I don't understand why- can anyone tell me?
finlep [7]

Answer:

It's C because we are adding a number on the x but here we skip 5 so it's 6, and on y we add 4 up but since we skipped 5 we add 8 and we get 24. 6, 24. You may say "but SpiritBear, 17 plus eight is 25" and that is true, but if you notice the lowest dot actually starts on 5, not 4 making C right.

Hope this helped and wasn't too confusing

Wouldn’t it be the 3rd answer 1/3 + 1/4 because you have to convert the dominators into 12 then you will get 4/12 and 3/12 then

what is the missing angle measurements for the isosceles triangle it has a picture of a triangle and has 70°
bulgar [2K]
Well if they part that has 70 degrees is congruent to any other side it is 70 + 70 which equals 140 and 360 which is a complete circle minus 140 is 220  the missing angels are there fore 70 and 220   or if the angle isnt congruent then the other sides must be so what plus itself on top of adding 70 will get us 360. lets find out what 220 in half is   since 220 and 70 equals 360. 110 is 220 in half so the sides missing on this could be 110 110
