Answer:
-6, 14, -26, 10x -4, -8x + -2x - 6
Step-by-step explanation:
So F(x) is setting that the values before the lines are equal to x and should be applied to the problem. Dont forget PEMDAS with these tho, they'll try to trick u like that.
So for the first one, f(0) you plug 0 where the x's are.
1.) 8(0)^2 +2(0) -6
0 + 0 - 6 = -6
2.) 8(2) +2(2) - 6
16+ 4-6= 20 - 6= 14
3.) 8(-2) + 2(-2) -6
-16 + -4 -6 = -26
On the ones where they leave the x there, you just have to leave the x. But don't forget distribution tho.
4.) 8(x+1) +2(x+1) -6
8x +8 + 2x + 2 -6
10x +10 -6 = 10x -4
5.) 8(-x) + 2(-x) -6
-8x + -2x -6
Answer:
Yes.
Step-by-step explanation:
going off of 60 it be 66, 72, then 78. meaning 6 is a multiple of 78.
You can draw a right triangle with one side being the known distance from Farmville to Louisville, 14 mi.
The other side, call it x, is the requested distance from Farmville to Stanton.
The hypotenuse is the 25 mi that separate Farmville and Stanton.
Use Pythagora's theorem:
25^2 = x^2 + 14^2
x^2 = 25^2 - 14 ^2 = 625 - 196 = 429
Take square root from both sides
x = √429 = 20,7 mi.
it went up: 375 *5 = 1875 feet total
it went down: 225 *6 = 1350 feet total
1875-1350 = 525
it is 525 feet above the ground
