Answer:

{a} {b} {c} {ab} {ac} {bc} {abc}

First, let's define a few varibles.

x = # of miles

y = # of days

z = total cost

Now, let's create our expression

z = $23.95y + $0.33x

Let's plug the numbers from our problem into our equation.

$150 = $23.95(2) + $0.33x

Simplify the right side

$150 = $47.9 + $0.33x

Subtract $47.9 from both sides

$102.1 = $0.33x

Divide both sides by $0.33

309 miles = x

Note, I rounded my answer down to the nearest whole number.

Answer:

Step-by-step explanation:

The fraction 5 divided by 1/2 looks like [tex]\frac{5}{1/2}[/tex]. It is difficult to divide with fractions but can be easier if you remember that dividing by a fraction is the same as multiplying by its reciprocal. A number's reciprocal is that number flipped by switching the numerator and the denominator. So, 3/5 becomes 5/3, and 1/2 becomes 2/1. Another way to state 2/1 is simply 2. Therefore, [tex]\frac{5}{1/2}[/tex] is really 5 * 2. 5 times 2 is 10, which is your answer.

The scaled drawing of a shape is a drawing in proportion to the original drawing. Xavier is not incorrect with his conclusion.

Given that:

[tex]k = 20cm[/tex] ---- the new scale

[tex]Length = 12\ units[/tex]

[tex]Width = 8\ units[/tex]

The dimension of the table on the new scale is:

[tex]Length = 20cm \times 12[/tex]

[tex]Length = 240cm[/tex]

[tex]Width = 20cm \times 8[/tex]

[tex]Width = 160cm[/tex]

On the original scale, the table dimension is:

[tex]Length = 15cm \times 12 = 180cm[/tex]

[tex]Width = 15cm \times 8 = 120cm[/tex]

By comparing both dimensions, we can conclude that Xavier is not incorrect with his conclusion.

Answer:

A'(-3, -2)

B'(-2, -1)

C'(-2, -2)

Step-by-step explanation:

The translation is (x - 7, y + 1).

That means subtract 7 from the x-coordinate and add 1 to the y-coordinate of each point.

Point A is (4, -3).

Subtract 7 from the x-coordinate 4 to get -3.

Add 1 to the y-coordinate -3 to get -2.

For point A, you get A'(-3, -2) after the translation.

Do the same with points B and C.

B(5, -2) ---> B'(5 - 7, -2 + 1) = B'(-2, -1)

C(5, -3) ---> C'(5 - 7, -3 + 1) = C'(-2, -2)

Step-by-step explanation:

First as per the given question,

[tex]7 \frac{9}{10} + \frac{5}{10} [/tex]

[tex] = \frac{79}{10} + \frac{5}{10} [/tex]

[tex] = \frac{84}{10} [/tex]

[tex] = 8 \frac{4}{10} [/tex]

= 8 4/10 (Solution)

Here,

As we look in Maria,

She used a method where first she separated then added and got the result same as the solution.

And,

As we look in Paul,

He also used a method where first he added then separated and got the result same as the solution.

As we see,

Both having same results as the solution irrespective of different methods so both are correct in their way.

Answer:

10.1

Step-by-step explanation:

I just put in a calculator and got the answer.

Given equations are,

4x - y = -2 ------(1)

x - 3y = 5 ------(2)

There are two variables in the equations 'x' and 'y'.

Coefficients of these variables in equation (1),

Coefficient of x = 4

Coefficient of y = -3

Similarly, constant terms of equations (1) and (2) are -2 and 5 respectively.

Matrix to solve these equations will be,

[tex]\begin{bmatrix}4 &-1 \\ 1 & -3\end{bmatrix}\begin{bmatrix}x\\y \end{bmatrix}=\begin{bmatrix}-2\\ 5\end{bmatrix}[/tex]

Therefore, Option (A) will be the correct option.

Step-by-step explanation:

f(x) = x² + 2x + 9

f(x + 1) = (x + 1)² + 2(x + 1) + 9 = x² + 2x + 1 + 2x + 2 + 9 = x² + 4x + 12

Answer:

r = 15

Step-by-step explanation:

These angles are supplementary which means they add up to 180:

6r - 4 + 94 = 180

6r + 90 = 180

6r = 180 - 90

6r = 90

r = 15

Answer:

-8 < r < 3

Step-by-step explanation:

Because you are trying to solve for r, all we have to do is isolate the variable.

To do this we can divide all 3 terms by -3, because that's what's in front of the r.

24/-3 > -3r/-3 > -9/-3

Dividing or multiplying by a negative number reverses this inequality, so the > signs must be flipped around to <

All that's left to do is simplify the fractions, and ensure that the inequality signs are flipped.

Answer:

B. [tex] {f}^{ - 1} (x) = \frac{1}{3} x + 2[/tex]

Step-by-step explanation:

[tex]f(x) = 3x - 6[/tex]

[tex]y = 3x - 6[/tex]

[tex]x = 3y - 6[/tex]

[tex]3y - 6 = x[/tex]

[tex]3y = x + 6[/tex]

[tex]y = \frac{1}{3} x + 2[/tex]
