Answer:
Step-by-step explanation:
f(x) = 4-x
g(x) = h
+k
g(f(x)) = 2-16x+26
so put f(x) in g(x)
h
+k
h((4-x)(4-x) + k
h(-8x+16)+k
if h = 2 , then
2-16x+32 + k
and we want 26 instead of 32 so subtract 6 so K = (-6)
2-16x+32 + (-6)
2-16x+32 - 6
2-16x+26
h=2
k=(-6)
Answer:
c
Step-by-step explanation:
Answer:
Area: 28 square ft
Perimeter: 22 ft
Step-by-step explanation:
To find the area:
A=Lw
A is area, L is length, w is width
A=4*7
A=28
The area is 28 <em>square</em> feet
To find the perimeter:
P=2L+2w
P=2(7)+2(4)
P=14+8
P=22
The perimeter is 22 feet.
Hope this helps!
a) +17 -9 = +8 . . . a profit of $8
b) +9 -5 = +4 . . . a rise of 4 cm
c) -6 -4 = -10 . . . a drop of 10 °C
_____
Each integer has a sign chosen with respect to some reference direction. We usually choose a rise or increase or profit to be the positive direction, so a drop or decrease or loss is then represented by a negative number.
