Answer:

A. 5 units

Step-by-step explanation:

Use the formula: √(x2−x1)2+(y2−y1)2

Solve:√((3-(-1))^(2)+((-1)-(-4))^(2))

You'll get the answer: 5

Mr. Akika has 30 24-cent and 33-cent stamps all told. The stamps are worth $8.91. How many of each kind of stamp does he have?

riadik2000 [5.3K]

Answer:

24-cent: 11
33-cent: 19

Step-by-step explanation:

I find it easiest to solve these using the variable to represent the number of the most-expensive item. Let x represent the number of 33-cent stamps. Then the total value (in cents) is ...

33x +24(30 -x) = 891

9x = 171 . . . . . . . . . . . . . subtract 24(30), collect terms

x = 19 . . . . . . . . . . . . divide by 9

30-x = 11 . . . . . . . find the number of 24-cent stamps

Mr. Akika had 11 24-cent stamps and 19 33-cent stamps.

<em>Additional comment</em>

You seem to have several of these to solve. They all have a similar solution.

If we let x represent the number of higher-value items, N, the total number of items, V the total value, and v1 and v2 the individual values (v2 > v1), the equation is ...

v2(x) +v1(N -x) = V

x(v2 -v1) = V -v1·N

x = (V -v1·N)/(v2 -v1) . . . . generic solution

Using this formula in the problem here, we find ...

x = (891 -24(30))/(33 -24) = 171/9 = 19 . . . as above

Which situation can be represented by 80x > 150 + 50x?

V125BC [204]

Answer:

All numbers greater than 5, i.e., $x>5$ .

Step-by-step explanation:

The given inequality is

$80x>150+50x$

Isolate variable terms on one side to find the solution.

Subtract 50x from both sides.

$80x-50x>150+50x-50x$

$30x>150$

Divide both sides by 30.

$\dfrac{30x}{30}>\dfrac{150}{30}$

$x>5$

It means, all the numbers which are greater than 5, are the solutions of the given inequality and 5 is not included in the solution set.

Writing the domain in words: negative infinity to three halves and three halves to infinity

So, Option A is correct.

Step-by-step explanation:

We need to find domain of the function: $f(x)=\frac{x-5}{2x-3}$

<u>Domain:</u>

The domain of function is defined as all the input values for which the function is defined.

In other words we can say that any value of x that makes the denominator zero is not considered as domain of function.

In the function given: $f(x)=\frac{x-5}{2x-3}$

if x= 3/2 then the denominator will be zero and the function will not be defined.

So, value of x should be x>3/2 or x<3/2

We can write domain as: (-∞,3/2)(3/2,∞)

3/2 can be written as three halves.

Writing the domain in words: negative infinity to three halves and three halves to infinity

So, Option A is correct.

Add the like terms: -3ab+-10a+-8a

Stolb23 [73]

-10a and -8a are like terms, but -3ab is not equivalent. With the two a terms, we have:

-10a-8a

a(-10-8)

-18a

We then add in the other term (-3ab) for a final result of -3ab+-18a. This can be factored alternatively as -3a(b+6).
