Answer:
Step-by-step explanation:
4x+2y = -24 -------------(i)
<u> -4x+y = 12 -</u>------------(ii)
add (i) &(ii) 3y = -12
y = -12/3
y = -4
Put y = (-4) in (i)
4x + 2*(-4) = -24
4x - 8 = -24
4x = -24 + 8
4x = -16
x = -16/4
x = -4
Answer:
See Below (it is correct)
Step-by-step explanation:
First point given ---- A(-3,0)
2nd point given ----- B(4,0)
The slope is the "change in quantity y" divided by "change in quantity x"
The change would be from 2nd point to 1st point. So,
Change in quantity y is 0 - 0 = 0
Change in quantity x is 4 - (-3) = 4 + 3 = 7
So, slope would be:
Slope = 0/7 = 0
The slope is 0 (which means it is a horizontal line)
Answer:
Step-by-step explanation:
When the first draw is done there are 9 red balls in a sample size of 21. So there probability of drawing a red ball will be 
When the second draw is done, there will be 12 yellow balls in a sample size of 20 since the first ball will not have been replaced into the bag. So the chance of someone drawing the second ball in the second draw is 
The probability of them happening in this order is the product of both probabilities:
About 7
because 5^2+5^2 is 50 and then you take the sq root of 50 which is about 7
77,543 rounded to the nearest ten is 77,540
