Answer:
y = -2x - 7
Step-by-step explanation:
x - 2y = 6
-2y = -x + 6
Divide the whole equation by (-2)
slope = 1/2
Slope of the line perpendicular to this line = -1/m = -1 ÷ (1/2)
(-3, - 1)
y -y1 = m(x -x1)
y - [-1] = -2(x - [-3])
y + 1 = -2(x + 3)
y + 1= x* (-2) + 3*(-2)
y + 1 = -2x - 6
y = -2x - 6 - 1
y = -2x - 7
Answer:
20:21
Step-by-step explanation:
Let's first start by converting each ratio so that the number of girls is the same
2:3
4:7
The least common multiple of 3 and 4 is 12 so...
8:12
12:21
We add 8 and 12 to get the number of junior members...
8+12=20
Then we put it in a ratio with the amount of adult members...
20:21
False cube root of 1 is plus 1 only.
Answer:48
Step-by-step explanation:
4x12=48
<span>factors of 30 are numbers by which 30 is divisible.
if we list out 30 as a product of factors 30 = 1 x 30
30 = 2 x 15
30 = 3 x 10
30 = 5 x 6
therefore all the factors of 30 are - 1,2,3,5,6,10,15,30
the numbers 3 and 6 add up to 9.
therefore the 2 factors that add up to 9 are 3 and 6</span>
