Answer:
(-9+√17)/8
Step-by-step explanation:
its an example of quadratic
Start at 14 on the number line. Since 25 is negative you’re going to be moving to the left. After 14 hops you’ll reach zero, you’re adding -25 so you’ll have to reach a total of 25 hops to the left. You have moved so far 14 hops so you still have 11 to go. Moving 11 more hops to the left results in -11. Now you have reached the total number of hops 25, the negative sign indicated you were moving towards the left. So 14+(-25)=-11
The walker's speed is
(913 miles) / (2.5 hours) = <em>365.2 miles per hour</em>
(Hey, I just solve um. I don't get into the philosophy.)
Y = x - 7 ---------- (1)
5x + 2y = 7 ------ (2)
Sub (1) into (2):
5x + 2(x -7) = 7
5x + 2x - 14 = 7
7x - 14 = 7
7x = 7 + 14
7x = 21
x = 3 ----- -sub into (1)
y = x - 7
y = 3 - 7
y = -4
Ans: x = 3, y = -4
65% (N=what percentage) because 13 over 20 divided by n over 100 = 20n = 13(100) = 20n=1300 and then to divide, 20n / 20 = 1300 / 20 = n= 65 or 65%
