Answer:
both equations reduce to y = -1/3x -2
Step-by-step explanation:
In each case, subtract the term not containing y and divide by the coefficient of y.
1. 6y = -2x -12 . . . . 12 was subtracted from both sides
y = -1/3x -2 . . . . . . the equation was divided by 6
__
2. 3y = -x -6 . . . . . . x was subtracted from both sides
y = -1/3x -2 . . . . . the equation was divided by 3
Answer:
Step-by-step explanation:
By using the Pythagorean theorem:
b^2+3^2=5^2
b^2+9=25
b=sqrt (25-9)
b=sqrt(16)
b=4
=> 4^2+7^2=c^2
16+49=c^2
65=c^2
=>c=sqrt(65)
c = (approximately) 8

Step-by-step explanation:
Answer:
30 minutes
Step-by-step explanation:
Find the unit rate (time per SINGLE kilometer).
5/5=1 18.75/5=3.75
Multiply 3.75 (unit rate) by 8.
3.75 x 8=30
42 because it is all of the sides have to be added up for the perimeter so the formula would be 14+14+7+7.
