Answer:
Slope= -4
Step-by-step explanation:
Slope is rise over run (y over x)
So, looking at the table, you can see that every time the y values went down by 8, the x values went up by 2.
So, the slope can be written as:
-8/2
Simplified to -4/1 or just -4
Answer:
x = - 3
Step-by-step explanation:
1 + x - 1 + 12x = 12x - 3
Subtract 12x from both sides.
1 + x - 1 = - 3
Combine like terms on the left side.
x = - 3
295/110,000. Hopefully this helped.
Answer: He run 7 high-speed intervals and 8 low-speed intervals.
Step-by-step explanation:
Let x = Number of high-speed intervals.
y= Number of low-speed intervals .
He runs high-speed intervals in 16 seconds, and low-speed intervals in 23 seconds, and he runs a combined total of 15 intervals in 4 minutes and 56 seconds.
4 min 56 sec = (4(60)+56) sec = 296 sec [ 1 minute = 60 seconds]
According to the question , we have the following linear equations :
Multiply (i)by 16 , we get
Subtract (iii) from (ii)
Put value of y in (i) , we get
Hence, he run 7 high-speed intervals and 8 low-speed intervals.
