Answer:
missing side length is 12
Step-by-step explanation:
similar means that all correlating pairs of sides have the same ratio (old side length) / (new side length).
so, when we know the ratio of one pair, we can apply it to any other side to calculate the correlating side.
we see, when we go from small to large, that we have the ratio 32/40 = 4/5.
so, multiplying the larger side by this, we get the shorter side.
15 × 4/5 = 3 × 4 = 12
the proportion part in your picture is a bit confusing :
yes,
x/15 = 32/40 = 32/40
I don't know, why this last expression was repeated.
x/15 = 32/40
x = 15×32/40 = 15×4/5 = 3×4 = 12
as you see we get of course the same result doing it that way.
Answer:
(-1, 7)
Step-by-step explanation:
2 unites left would movie from 1 to -1.
1 unit down would move from 8 to 7.
Answer:
D = -1, -1, 2, 5
R = 0, 2, 3, 7
✅It is NOT A FUNCTION
Step-by-step explanation:
D (Domain) = input values (x-values)
D = -1, -1, 2, 5
R (Range) = output values
R = 0, 2, 3, 7
✅It is not a function because an x-value, -1, has two different y-values, 7 and 2, assigned to it.
