You just divide. 38÷12=3.166~ $3.17
Answer:
negative
Step-by-step explanation:
looking at the slope of the straight line, a positive slope will begin on the 1st quadrant and end at the 3rd quadrant
meaning if the slope is negative, it will begin on the 2nd quadrant and end on the 4th quadrant
Answer:
C. y +3 = x +3
Step-by-step explanation:
We need to find in below option x has direct variation with y.
We solve for each;
A. 
From above equation we can state that 2 times y is equal to 7 less than 3 times of x.
Hence it doesn't represent direct variation.
B. 
Solving above expression we get;

From above equation we can state that y is equal to 10 more than x.
Hence it doesn't represent direct variation.
C. 
Solving above expression we get;

From above equation we can state that y is equal to x.
Hence it represent direct variation.
D. 
Solving above expression we get;

From above equation we can state that 4 times y is equal to 2 less than 4 times of x.
Hence it doesn't represent direct variation.
Hence the Answer which represent direct variation of x and y is,
C. 
Step-by-step explanation:
m=5/7
m1=m2=5/7
L;y-(-2)=5/7(x-(-5)
y+2=5/7(x+5)
7y+14=5X+25
7y-5x=11 is parallel lines
m1*m2=-1 is perpendicular lines
m2=-1*7/5
m2=-7/5
L;y+2=-7/5(x+5)
5Y+10=-7x-35
5y+7x=-45 is perpendicular lines
Here, exterior angles are 1, 2, 7 & 8 as they are outside the parallel lines, & among them, alternates are: 1 with 7 and 2 & 8. 1 & 7 is not in option but 2 and 8 is there in C
In short, Your Answer would be Option C
Hope this helps!
