Answer:
Step-by-step explanation:
The distance between two points is
d^2=(y2-y1)^2+(x2-x1)^2
D) points (0,0) and (9,12)
d^2=(9-0)^2+(12-0)^2
d^2=81+144
d^2=225
d=15
E) points (1,2) and (-3,5)
d^2=(-3-1)^2+(5-2)^2
d^2=16+9
d^2=25
d=5
Answer:
Perpendicular.
Step-by-step explanation:
Since x is postive in one equation and negative in the other, it is an indicator that both x's go in different directions.
Here it is graphed:
Answer:
Multiply by 18
Step-by-step explanation:
Given
Required
Eliminate the fraction
To eliminate the fraction, we first determine the LCM of the denominators (3, 6 and 9)
This is show below:
List out the multiplies of 3, 6 and 9
The least common multiple is 18.
Hence, when both sides of the equation is multiplied by 18, the fraction is eliminated;
See proof
<em>The fraction is eliminated</em>
Y = x + 6
y has to be greater than or equal to 6
x has to be greater than or equal to 0
12 + 1(h) = the average amount
h = hour (how many hours it’s snowed)
