Answer:
Is this a question. If so I will change my answer
Step-by-step explanation:
V=s³
SA=6s²
sub 2 for s
V=2³=8 cubic inches
SA=6(2²)=6(4)=24 square inches
The answer is -9 • (x + 2) • (x - 1)2
y = x + 2
Step-by-step explanation:
General formula for any straight line:
y = mx + c
Where
m = gradient
c = constant
m = y2 - y1/x2 - x1
m = (4 - ( -2))/(2 - ( -4))
m = 6/6
m = 1
y = (1)x + c
y = x + c
Substitute any coordinate from the line of the equation.
4 = 2 + c
c = 2
substitute m and c into general formula
y = mx + c
y = x + 2
Answer:
The correct option is b.
Step-by-step explanation:
The given function is
We need to find the value of f(-2). It means we have to find the value of given function at x=-2.
Substitute x=-2 in the given function to find the value of f(-2).
On simplification we get
The value of f(-2) is 11. Therefore the correct option is b.
