The first 3 are functions as their x coordinate (number on the left side of the parentheses) is not repeated in any of the other parentheses
Baswically find the slope of each line
slope=rise/run
for the graph we see that it rises 120 over 2 hours or 120/2 or 60mph
for the other one is where miles is rise and hours is run
2 hours to 90 miles
3 hours to 135 miles
change from 2 to 3 is 1 hour
change from 90 to 135 is 45 miles
so 45mph
60>45
the guzmans travel at lower average speed
Answer:
65 coins
Step-by-step explanation:
Set this problem up with a porportion.
After that, cross multiple and divide.
25 times 260. Then divide by 100. That is then your answer.
When we factorise an expression, we are looking for simple factors that multiply to get the original expression. Usually it is very natural to factorise something like a quadratic in x. For example:
x^2 + 3x + 2 = (x+1)(x+2)
But there are other situations where factorisation can be applied. Take this quadratic:
x^2 - 9x = x(x-9)
This second example is closer to the question in hand. Just like x was a common factor to both x^2 and -9x, we are looking for a common factor to both 6b and 24bc. The common factor is 6b.
Hence 6b + 24bc = 6b(1 + 4c).
I hope this helps you :)
