Question 5

Mathematics
1 answer:
Mice21 [21]3 years ago
4 0

Answer:

The missing value is 2

Step-by-step explanation:

A direct variation satisfies the equation y=kx.

Since the point (-18, 12) lies on this line, it must satisfy this equation.

\implies 12=-18k

k=-\frac{12}{18} =-\frac{2}{3}

Hence the equation of this line is y=-\frac{2}{3}x

Now we substitute x=-3 to find y.

y=-\frac{2}{3}*-3=2

Therefore the missing value is 2

How many sides do 1980 have
mel-nik [20]

Answer:

13 sides

Step-by-step explanation:

1980 = (n − 2)×180         Formula for number of sides

n − 2 = 1980/180            Divide both sides by 180

n - 2 = 11            

  + 2   + 2                       Add 2 to both sides

n = 13
