Answer:
83% are boys
Step-by-step explanation:
Im not sure if you have to round but you take the total number of family members (6) and divide it by how many boys (5) which would be 0.8333333 which you can round to either 80 or 83
Answer:
uₙ₊₁ = uₙ + ¹/₂
Step-by-step explanation:
uₙ₊₁ = uₙ + d
u₈ = 3
u₁₀₀ = 49
We can establish the following:
u₉ = 3 + d
u₁₀ = (3 + d) + d = 3 + 2d
u₁₁ = (3 + 2d) + d = 3 + 3d
so...
u₈₊ₐ = 3 + ad
u₁₀₀ = u₈₊₉₂ = 3 + 92d
3 + 92d = 49
92d = 46
d = ¹/₂
∴ uₙ₊₁ = uₙ + ¹/₂
Step-by-step explanation:
I think substitution would be the easiest since you already have one of the variables solved for.
(You can just set the equations equal to each other since they both equal y).
Now, to get the points, plug in x = 4 and x = -1 into one of the equations (I'm going to plug them into y = x+1 because that one is much simpler)
So, your final points are:
(4,5) and (-1,0)
Answer: it would take jenny 9 hours to do alone
Step-by-step explanation:
Given:
The inequality is:
To find:
The solution for the given inequality and graph of it.
Solution:
We have,
Divide both sides by -20 and change the sign of inequality because inequality is divided by a negative number.
Therefore, the solution for the given inequality is .
All the value less than 4 are in the solution set. It means all the values on the left side of 4 are in the solution set.
Since 4 is not included in the solution set, therefore there is an open circle at 4.
The graph for the given inequality is shown below:
