Answer:
y= 3/4x
Step-by-step explanation:
Points on the graph
the equation based on the difference in points:
Step-by-step explanation:
2 (yellow) / 3.5 (blue)
that means, out of 2+3.5 = 5.5 units 2 are yellow, and 3.5 units are blue.
now in a 3 / 4.5 ratio we have 3+4.5 = 7.5 units, where 3 units are yellow and 4.5 units are blue.
let's bring both ratios to the same denominator (bottom part of the fraction).
if we multiply 3.5 by 2 we get 7. and multiplying 4.5 by 2 gives us 9.
and the smallest common multiple of 7 and 9 is 63.
so, let's bring both fraction to .../63.
3.5 × 2 × 9 = 63
so, the ratio is
2×2×9/63 = 36/63
and
4.5 × 2 × 7 = 63
so, that ratio is then
3 × 2 × 7 / 63 = 42/63
now we can see clearly that the first ratio
2/3.5 = 36/63 has fewer units of yellow in the mix than the second ratio
3/4.5 = 42/63.
so, the second mixture is more yellow.

Answer:
29°, 58°, and 93°
Step-by-step explanation:
If the angles opposite are equal, the sides are equal. In order to have three different side lengths, you must have <em>three different angles</em>.
Answer:
n=6
Step-by-step explanation:
(n-18)/3 = -4
multiply by 3
n-18 = -12
add 18
n = 6
