My name is Ann [436]3 years ago
4 0

Answer:

When she gave out the 12, that must mean that she gave out another less than the half she gave out in the morning, so I'm saying the answer is 44

Step-by-step explanation:

Because if you really think of it, use 40. 40 ÷ 2 = 20 - 12 = 8, REALLY CLOSE!

44 ÷ 2 = 22-12 = 10. YAAAS GOT IT! So its 44

What is f(5) if f(1) = 3.2 and f(x + 1) = (f(x))?
scoray [572]

Answer:

The value of f(5) is 3.2.

Step-by-step explanation:

It is given that f(1) = 3.2 and

f(x+1)=f(x)

Substitute x=1 in the above equation.

f(1+1)=f(1)

f(2)=3.2

Substitute x=2 in the given equation.

f(2+1)=f(2)

f(3)=3.2

Substitute x=3 in the given equation.

f(3+1)=f(3)

f(4)=3.2

Substitute x=4 in the given equation.

f(4+1)=f(4)

f(5)=3.2

Therefore the value of f(5) is 3.2.

A direct variation function contains the points (-9, -3) and (-12,4). Which equation represents the function?
Triss [41]

Answer:

y = -\frac{7x}{3} - 24

Step-by-step explanation:

We can model this function using the equation of a line:

y = ax + b

Where a is the slope of the line and b is the y-intercept.

To find the values of a and b, we can use the two points given:

(-9, -3):

-3 = a * (-9) + b

-9a + b = -3

(-12, 4):

4 = a * (-12) + b

-12a + b = 4

If we subtract the second equation from the first one, we have:

-12a + b - (-9a + b) = 4 - (-3)

-12a + 9a = 4 + 3

-3a = 7

a = -7/3

Then, finding the value of b, we have:

-12a + b = 4

28 + b = 4

b = -24

So the equation is:

y = -\frac{7x}{3} - 24
