Evaluate the expression by substituing the given values in.

[tex] \displaystyle \large{2(5)- 6( - 4)+ 3( - 3)} \\ \displaystyle \large{10- ( - 24)+ ( - 9)}[/tex]

Simplify the expression.

[tex] \displaystyle \large{10 + 24 - 9} \\ \displaystyle \large{34- 9} \\ \displaystyle \large \boxed {25}[/tex]

Therefore, the value of the expression is 25.

Answer:

2nd option

Step-by-step explanation:

note that

5n ← generates multiples of 5, that is

5 × 1 = 5

5 × 2 = 10

5 × 3 = 15

5 × 4 = 20 , etc

5, 10, 15, 20, ....... are multiples of 5

but 5n + 1 does not generate multiples of 5 as

5 + 1 = 6

10 + 1 = 11

15 + 1 = 16

20 + 1 = 21

6, 11, 16, 21 are not multiples of 5

Tables are used to show the relationship between variables in a visual form. The equation of the situation is: [tex]y = 7x[/tex]

The complete table is as follows:

[tex]\left[\begin{array}{cccccc}{Pages}&1&2&4&6&8\\{Photos}&7&14&28&42&56\end{array}\right][/tex]

Given that:

[tex]2\ page = 14\ photos[/tex]

Let:

[tex]y \to pages[/tex]

[tex]x \to photos[/tex]

So, we have:

[tex]2y = 14x[/tex]

Divide by 2

[tex]y = 7x[/tex]

To fill the table, we simply multiply both sides by the same constant.

Multiply by 0.5

[tex]2\ page \times 0.5= 14\ photos \times 0.5[/tex]

[tex]1\ page = 7\ photos[/tex]

Multiply by 2

[tex]2\ page \times 2 = 14\ photos \times 2[/tex]

[tex]4\ page = 28\ photos[/tex]

Multiply by 3

[tex]2\ page \times 3 = 14\ photos \times 3[/tex]

[tex]6\ page = 42\ photos[/tex]

So, the table is as follows:

[tex]\left[\begin{array}{cccccc}{Pages}&1&2&4&6&8\\{Photos}&7&14&28&42&56\end{array}\right][/tex]

Answer:

  a = 1

Step-by-step explanation:

The slope of the inverse of a linear function is the inverse of the slope of the original function.

The slope of g(x) is the coefficient of x: 1.

The inverse of 1 is 1/1 = 1.

The slope of the function g^-1(x) is 1, so a=1.

Answer:

(0,-3)

(8,0)

Step-by-step explanation:

Putting x = 0

[tex]3(0) - 8y = 24[/tex]

[tex] - 8y = 24[/tex]

[tex]y = \dfrac{ - 24}{8} [/tex]

[tex]y = - 3[/tex]

x - intercept = (0.-3)

Putting y = 0

[tex]3x - 8(0) = 24[/tex]

[tex]3x = 24[/tex]

[tex]x = \dfrac{24}{3} [/tex]

[tex]x = 8[/tex]

y - intercept = (8,0)

Answer:

x-intercept is 8

y-intercept is -3

Step-by-step explanation:

We can put the equation into slope intercept form to find the y-intercept.

3x - 8y = 24

~Subtract 3x to both sides

-8y = 24 - 3x

~Divide -8 to everything

y = -3 + 3/8x

~Reorder

y = 3/8x - 3

In slope intercept form we know that m = slope and b = y-intercept in the formula [ y = mx + b ] so we know that the y-intercept will be -3. To find the x intercept we can substitute 0 for y and solve for x.

0 = 3/8x - 3

3 = 3/8x

x = 8

Answer:

3.25

Step-by-step explanation:

1 hong kong dollar = 0.13 cents in us dollars

0.13x25=3.25

The value of 25 Hong Kong dollars in U.S dollar is $3.1969

Given that :

$1 = 7.82 Hong Kong dollars

Let the equivalent Number of U.S dollars = p

This means that :

$1 = 7.82 Hong Kong dollars

$1 = 7.82 Hong Kong dollars $p = 25

Cross multiply :

25 × 1 = 7.82 × p

25 = 7.82p

Divide both sides by 7.82

25 / 7.82 = p

p = $3.1969

Hence, 25 Hong Kong dollars is 3.1969 U.S dollars.

hi <3

multiply the coefficient of x^2 with the last value:

2 x 3 = 6

you need to find a value that multiplies to give 6 and adds to give 5

this would be 3 and 2

now you have:

(x + 3)(x + 2)

we need to incorporate the 2 into it

you can divide the 2 by 2 so that part is fine. however, as 3 cant be divided by 2, you have to carry the 2 up as a coefficient for x

your final answer works out to be:

(2x + 3)(x + 1)

Answer:

x = 55

Step-by-step explanation:

To find the value of x

3x - 35 = 130 (vertically opposite angles are equal)

3x = 130 +35

3x = 165

x = 165/3

x = 55

The numbers are ordered, such that the first number (the largest one) is:

(5 + 1/2)

And the last number (the smaller one) is (5 + 1/3). Only by knowing this, we will see that the correct options are A and C.

We want to see which of the following numbers is not on the list:

A) √25

B) 5.45

C) 5 12  

D) 5.34

One of these numbers can only be in the list if it is larger than  (5 + 1/3) and smaller than (5 + 1/2).

To see this easier, let´s rewrite both of these:

5 + 1/2 = 5 + 0.5 = 5.5

5 + 1/3 = 5 + 0.33 = 5.33

Then if a number is smaller than 5.33, the number can't be in the list.

Here we can see two numbers that are smaller than 5.33

These are:

Option A) √25 = 5 < 5.33

Option C) 5.12 < 5.33

And there is no number larger than 5.5

Concluding, the numbers that are not in Demichael's list are:

√25 and 5.12

Answer:

Slope = ⅓ Y-intercept = -2

Step-by-step explanation:

by transforming the equation to y= ⅓x -2

then it becomes Y= ⅓x +(-2)

then you should get m= ⅓ and b = -2

Step-by-step explanation:

(a)

y = mx + b

y = (1/3)x + (-2)

y = 1/3x - 2

(b)

x - 3y = 6

x - 3(0) = 6

x - 0 = 6

x = 6
