What is the equation of the line with slope of – 5 and passes through (2, – 3)?
1 answer:
Answer:
y = -5x + 7
Step-by-step explanation:
Graph has a slope of -5, which is the gradient
y = -5x + c
To find c you have to sub in the point (2, -3)
-3 = -5(2) + c
-3 + 10 = c
c = 7
Hence equation is:
y = -5x + 7

Answer:
6 2/3 minutes
Step-by-step explanation:
3 hours on frames 3 x 60 = 180 minutes total
180/27 frames = 6.66667 or 6 2/3 minutes.
2(6x+20) +2(8x-16)=180
12x+16x+40-32=180
28x+8=180
X=180-8/28=6

Answer:
The initial cost is $20, and it adds $5per hour
Step-by-step explanation:
Read the graph
Step-by-step explanation:
60% of original price X = $180
60/100 × X = $180
60X/100= $180( cross multiply)
60X= 18000
X= 18000÷60
X= $300
