A college student needs 11 classes that are worth a total of 40 credits in order to complete her degree. The college offers both

4-credit classes and 3-credit classes.
Which system of equations can be used to determine f, the number of 4-credit classes the student can take to complete her degree, and h, the number of 3-credit classes?
A) f + h = 40
4h + 3f = 11
B) f + h = 11
4h + 3f = 40
C) f + h = 40
4f + 3h = 11
D) f + h = 11
4f + 3h = 40

Answer: The correct answer is Choice D.

In this problem, there are 2 different  equations. The first ones adds the 2 variables together to get a total of 11.
f + h = 11

For the second equation, each four credit class gets multiplied by 4. And each 3 credit class gets multiplied by 3. Then, they are added together to get 40.
4f + 3h = 40

Arlecino [84]

Interest rate= 0.083%

Step-by-step explanation:

Principal= $5000 Amount= $10000 Time period= 12 years

A=Amount, P= Principal, I= Simple Interest r= Rate of interest t= Time period

A= P+ I\\10000= 5000+ I\\I=10000-5000=5000\\I=Prt\\5000=5000*r*12\\r=5000/5000*12\\r=5000/60000\\r=0.083

The graph of g(x)=(1.5)x−2 is shown. Which equation is an asymptote of this function?
olga nikolaevna [1]

Answer:

y=0

Step-by-step explanation:

asymptote formula x=-b/2a

so -(-2)/2(1.5)=2/3

then you replace it for finding the other point

g(2/3)=1.5(2/3)-3=0

y=0

Consider the graphs of f (x) = StartAbsoluteValue x EndAbsoluteValue + 1 and g (x) = StartFraction 1 Over x cubed EndFraction. T
Westkost [7]

Answer:

We have the functions:

f(x) = IxI + 1

g(x) = 1/x^3.

Now, we know that the composite functions do not permute.

How we can prove this?

First, two composite functions are commutative if:

f(g(x)) = g(f(x))

Well, you could use brute force (just replace the values and see if the composite functions are commutative or not)

But i will use a more elegant way.

We can notice two things:

g(x) has a discontinuity at x = 0.

so:

f(g(x)) = I 1/x^3 I + 1

still has a discontinuty at x = 0, but:

g(f(x)) = 1/( IxI + 1)^3

here the denominator is IxI + 1, is never equal to zero.

So now we do not have a discontinuity.

Then the composite functions can not be commutative.

he ratio table below describes the relationship between grapes and blueberries in a fruit salad. Fruit Salad Grapes (cups) Blueb
scoray [572]
The first thing you should do for this case is to graph the data you have in the statement to see the relationship between grapes and blueberries.
 The function represented by the table is
 y = 0.25x
 Then, as Mandie is making 15 glasses of fruit salad, we have:
 y + x = 15
 We have two equations and two unknowns that we must solve.
 y = 0.25x
 y + x = 15
 Resolving
 For x: 
 0.25x + x = 15
 1.25x = 15
 x = 15 / 1.25 = 12
 For y: 
 y = 0.25x = 0.25 (12) = 3
 Answer
 The ratio of grapes to blueberries she should use is 12: 3
