Y^2 - 10y + 16
the last sign in ur problem...the one before the 16..it is a +.....this means that both ur factors will have the same sign......the first sign...the one before the 10y is a -....this means that both ur factors will have a negative sign
now, we have to find 2 numbers, then when added = -10 and when multiplied = 16........-8 + (-2) = -10......-8 * -2 = 16....so ur numbers are -8 and -2
y^2 - 10y + 16
(y - 2)(y - 8) <===
Answer:
See answers below
Step-by-step explanation:
During the Boston Marathon, a What are the unit rates for this situation? (How far can they run in 1 hour and how long does it take to run 1 mile?)
If a certain runner averages running 25 miles in 5 hours, then
25miles = 5hrs
To determine how far they can run in 1 hour, then;
X = 1hr
Divide both expressions
25/x = 5/1
5x = 25
X = 5miles
Hence the runner can run 5miles in an hour
Similarly if
25miles =1hr
1mile = y
25y = 1
Y = 1/25
Y = 0.04hrs
Hence the time taken to run 1mile is 0.04hrs
Because when we divide that by itslef you get the exact same number
Answer:
<u>y = 1.46 * 10⁶ x</u>
Step-by-step explanation:
We can write the following equation:
Let x to represent the number of blue whales and,
let y to represent the total krill eaten by x blue whales per year
1'460,000 = 1.46 * 10⁶
<u>y = 1.46 * 10⁶ x</u>
