Answer:
Step-by-step explanation:
The domain are all the x values
(-7,-3), (-4,1), (1,-4), (6,3)
x here is from -7 to 6
domain ∈ [-7, 6]
The range are all the y values
(1,-4), (-7,-3), (-4,1), (6,3)
y here is from -4 to 3
range ∈ [-4, 3]
Answer:
-13734
Step-by-step explanation:
We're going to use pemdas for this equation.
Since there are no parenthesis we move on to exponents, which we do have, so we would cube 24, which gets us 13,824.
Next we subtract 90 from 13,824 which gives us our answer of -13,734
ok so the easy way is this
Marc says he will have 20 if he doubles his cards.
if u divide 20 by 2 = 10

10-3 = 7
He started with 7 cards
I answered b and c.
Answer:
162°
Step-by-step explanation:
They are on a straight line so add to 180
8x + 10 + 2x - 20 = 180
10x - 10 = 180
10x = 190
x = 19
We want AXB so 8x + 10 where x = 19
8(19) + 10 = 162 so it is 162°
