Answer:

  (D)  -1.3 + 1.9

Step-by-step explanation:

The number being subtracted in the given expression is -1.9. The opposite of that number is +1.9.

If we are to show equivalence of subtraction and adding the opposite, we expect to do so with ...

  [tex]-1.3-(-1.9)=\boxed{-1.3+1.9}[/tex]

This is not a choice that is presented in this problem statement, so we suppose it is D (not shown).

Using interval notation, the domain off is [- 3, 5] and the domain of g is [- 2, 7] . On what domain is f defined

Answers

Note: I am assuming you mean ''on what domain is f+g is defined''.

Answer:

We conclude that

Dom(f+g) = [-2, 5]

Step-by-step explanation:

Given the domain of f

[-3, 5]

Given the domain of g

[-2, 7]

The domain of a composition f+g would include the intersection of both domains.

In other words, the domain of a composition f+g includes all the inputs of x-values that are in the domain of both functions i.e. f and g.

so

Domain of f = [-3, 5]

The x-values lie in the domain of f interval are:

x = -3, -2, 1, 0, 1, 2, 3, 4, 5

Domain of g = [-2, 7]

The x-values lie in the domain of g interval are:

x = -2, 1, 0, 1, 2, 3, 4, 5, 6, 7

Therefore, the common x-values in both f and g would be:

-2, 1, 0, 1, 2, 3, 4, 5

Thus, we conclude that

Dom(f+g) = [-2, 5]

The price of Stock A at 9 A.M. Was ​$12.53. Since​ then, the price has been increasing at the rate of ​$0.12 each hour. At noon the price of Stock B was ​$13.28. It begins to decrease at the rate of ​$0.09 each hour. If the two rates​ continue, in how many hours will the prices of the two stocks be the​ same?

Answers

Answer:

1.8571428 hours

Step-by-step explanation:

Given that :

Price of stock A at 9 am = $12.53

Rate of increase = $0.12 per hour

Price of stock B at noon = $13.28

Rate of Decrease = $0.09 per hour

Let number of hours = x

Price of stock A at noon :12.53 + 0.12(3) = 12.89

12.89 + 0.12x = 13.28 - 0.09x

0.12x + 0.09x = 13.28 - 12.89

0.21x = 0.39

x = 0.39 / 0.21

x = 1.8571428

Hence the prices of the stock will be the at about 1.857 hours

The measures of the angles of a triangle are shown in the figure below. Solve
for x.

Answers

Answer:

[tex]x = 46[/tex]

Step-by-step explanation:

Given

The three angles in the triangle are: x, 34 and 100

Required

Determine the value of x

Angles in a triangle add up to 180.

So, we have:

[tex]x + 34 + 100 = 180[/tex]

[tex]x + 134 = 180[/tex]

Subtract 134 from both sides

[tex]x + 134 - 134 = 180 - 134[/tex]

[tex]x = 180 - 134[/tex]

[tex]x = 46[/tex]

Hence, the measure of x is 46

Answers

9514 1404 393

Answer:

3 inches ⇒ 75 miles7 inches ⇒ 175 miles10 inches ⇒ 250 miles

Step-by-step explanation:

Each inch is 25 miles, so the number of miles is 25 times the number of inches.

  3 in ⇒ (3×25 mi) = 75 mi

  7 in ⇒ (7×25 mi) = 175 mi

  10 in ⇒ (10×25 mi) = 250 mi

How many groups of 1/2 days are in 1 week? Write a multiplication equation or a division equation to represent the question, then answer the question. *​

Answers

Answer:

14 groups

Step-by-step explanation:

Given

[tex]Groupings = \frac{1}{2}\ day[/tex]

[tex]Duration = 1\ week[/tex]

Required

Determine the number of group in the week

To do this, we simply divide the duration by the number half day group.

This gives:

[tex]Group = \frac{Duration}{Groupings}[/tex]

[tex]Group = \frac{1\ week}{1/2\ days}[/tex]

Convert week to days

[tex]Group = \frac{7\ days}{1/2\ days}[/tex]

[tex]Group = \frac{7}{1/2}[/tex]

[tex]Group = 7 / \frac{1}{2}[/tex]

Convert to multiplication

[tex]Group = 7 * \frac{2}{1}[/tex]

[tex]Group = \frac{14}{1}[/tex]

[tex]Group = 14[/tex]

Hence, there are 14 groups

solve for x
3(x - 2) = 6x - 12

Answers

Answer:

The answer is 2

Step-by-step explanation:

Here's how I got it:

3(x - 2) = 6x - 12

Multiply 3 times x and 3 times 2, this is what you would get

3x - 6 = 6x - 12

Then, subtract the lowest x with the bigger X, this way you would have x on one side:

3x - 6 = 6x - 12

-3x        -3x

This is what you should have after this:

-6 = 3x - 12

Now, to get the variable (letter that represents a number) by itself, you have to add 12 to both sides like this:

-6 = 3x - 12

+12        +12

You would get this:

6 = 3x

Finally, you have to get x by itself, so you have to divide 3 on both sides like this

6/3 = 3/3 x

That's why, your answer is 2

Solve by using elimination. Express your answer as an ordered pair.

Answers

Answer:

(-2, 5)

Step-by-step explanation:

we subtract 6x+3y=3 by 2x+3y=11 to get 4x=-8.

we divide both sides by 4 to get x. x=-2

We subsitute -2 for the second equation to get:

2(-2)+3y=11

=-4+3y=11

=3y=15

y=5

Greetings again.

The answer is (-2,5)

Explanation:

What we need to do is to eliminate either x-term or y-term. Eliminating the terms that you don't have to multiply to get the same terms for both equations is better.

For this one, there're no terms that make 0.

And what do we do if there are no terms that can be eliminated?

The answer is, multiply one of the equation by -1. To make another equation have opposite negative and positive side. -3y + 3y = 0.

I'll multiply -1 in the second equation.

[tex]2x+3y=11[/tex]

Multiply the whole equation by -1.

[tex]2x(-1)+3y(-1)=11(-1)\\-2x-3y=-11[/tex]

Remind that negative multiply positive equal negative.

Now then we replace the old equation with -2x - 3y = -11

[tex]\left \{ {{6x+3y=3} \atop {-2x-3y=-11}} \right.[/tex]

Then add/subtract vertically.

6x-2x = 4x

3y - 3y = 0

3 - 11 = -8

Therefore, we get 4x = -8

[tex]4x=-8\\x=-2[/tex]

Because this is the system of two linear equations. We need to find the y-term/value too.

Substitute x = -2 in any given equations. choose any equations you'd like to substitute in. For me, I'll substitute in the equation with less coefficient value and that is the second equation.

[tex]2x+3y=11[/tex]

Substitute x = -2 in the equation.

[tex]2(-2)+3y=11\\-4+3y=11\\3y=11+4\\3y=15\\y=5[/tex]

Thus, when x = -2, y = 5. Since you want the answer as an ordered pairs. The answer is (-2,5)
