Step-by-step explanation:
Consider the line y=4/3x + 3
-
Find the equation of the line that is perpendicular to this line and passes through the point (-9, -5)
Find the equation of the line that is parallel to this line and passes through the point (-9, -5).
The scale factor is 0.75 or 3/4
TR/EZ=9/12=3/4
Answer:
70%
Step-by-step explanation:
First find the ones that still need to be installed
270-81
189
Percent to be done = number to be installed / total
=189/270 =.7
Change to percent form = .7 *100% = 70%
Answer:
The Ratios are Proportional
Step-by-step explanation:
Let,
R1 = 48 / 72 ----- (1)
R2 = 6/9 ------ (2)
If we divide right hand side of above equation by 8, we get,

Therefore, it means that, in simplified form, both ratios are same and hence proportional.
R1 : R2 = 6/9 : 6/9
