Answer:
zero
Step-by-step explanation:
slope = y2-y1 / x2-x1
Answer:
(x-1)(x-1)
Step-by-step explanation:
hello :
(x+2) ²-6 (x+ 2) +9 =(x+2) ²-2×(<em>3</em>) (x+ 2) +<em>3²</em>
by identity : (a-b)² = a²-2ab+b²
let : a=x+2 and b= <em>3</em>
(x+2) ²-6 (x+ 2) +9 =(x+2) ²-2×(<em>3</em>) (x+ 2) +<em>3²=</em> ((<em>x+2)-3</em>)<em>²= (</em>x+2-3)² = (x-1)²=
(x-1)(x-1)
Answer:
y varies as √(x+5)
Step-by-step explanation:
y varies as √(x+5)
y= k√(x+5)
k is a constant connecting the two sides.
therefore
k=y/√(x+5)
k=4/√(-1+5)
k= 4/√4
k=4/2
k=2
Y when x=11
y=k√(x+5)
y=2√(11+5)
y=2√16
y=2*4
y=8
After a 25% discount...means that u paid 75%
so 75% of the original cost is 18.50...
0.75x = 18.50.....with x being the original cost
x = 18.50 / 0.75
x = 24.666 rounds to 24.67 <==
