Answer:
- y = -3/5x - 6 or 3x + 5y = -30
Step-by-step explanation:
<u>Given line:</u>
<u>Converting into slope-intercept form:</u>
- 3x + 5y = 15
- 5y = - 3x + 15
- y = -3/5x + 3
<u>Parallel lines have the same slope, so the parallel line will be:</u>
<u>Using given point (-5, -3) finding the y-intercept:</u>
- -3 = -3/5(-5) + b
- -3 = 3 + b
- b = -3 - 3
- b = -6
<u>So the line is:</u>
<u>Or converted into standard form:</u>
- y = - 3/5x - 6
- 3/5x + y = -6
- 3x + 5y = -30
Answer: 52:3
Step-by-step explanation:
260 divided by 5 = 52
15 divided by 5 = 3
260:15 = 52:3
Answer: 240 km
Step-by-step explanation:
From the graph :
50 miles = 80km
1 miles = 80/50 km
Therefore :
150 miles = 80/50 x 150
150 miles = 240 km
Answer:
D. 9 meters
Step-by-step explanation:
AB = CD, so 9x-27=2x+1.
If you get like terms on the same side you get 7x=28
If you simplify by dividing everything by 7, you get x=4
If you plug 4 in as x into the expression 2x+1, you get 9.
Answer:
The expression that can be used it -12.6+-8.7=-21.3
Step-by-step explanation:
Make sure you look at what I put because it is negative 12.6 AND negative 8.7 which is why there is an addition mark in between them both
