replace the points and get 10

The value of the given expression (5/3)(3x - 6) - (6 - 4x) at x = 5 is 29.

According to the given question.

We have an expression (5/3)(3x - 6) - (6 - 4x).

So, the value of the given expression (5/3)(3x - 6) - (6 - 4x) at x = 5 is given by

(5/3)(3x - 6) - (6 - 4x)

= 5x - 10 - (6 - 4x)               (by distributive rule)

= 5x - 10 - 6 + 4x

= 9x - 16

= 9(5) - 16                 (at x = 5)

= 29

Hence, the value of the given expression (5/3)(3x - 6) - (6 - 4x) at x = 5 is 29.

Answer:

The other number is (-18/7)

Step-by-step explanation:

Let the other rational number be 'x'.

  [tex]\sf x * \dfrac{7}{9}= \dfrac{-14}{7}[/tex]

       [tex]\sf x = \dfrac{-14}{7} \div \dfrac{7}{9}[/tex]

Now, use KCF method.

       [tex]\sf x = \dfrac{-14}{7}*\dfrac{9}{7}\\\\x = -2* \dfrac{9}{7}\\\\x = \dfrac{-18}{7}[/tex]

Answer:

-18/7

Step-by-step explanation:

let the unknown no be y

7/9×y= -14/7

7y/9= -14/7

cross multiply

-14×9=7y×7

divide both sides by 7

-2×9=7y

-18=7y

divide both sides by the coefficient of y which is 7

y= -18/7

The final price of the smart phone if you use the store credit card is $375.15.

A discount is when the price of an item is marked down. An item becomes cheaper when it is discounted.

Percentage is the fraction of an amount expressed as an amount out of 100. Percentage is a measure of frequency. The sign used to represent percentage is %.

Price of the smartphone after 35% is discounted : (1 - percentage decrease) x original price

(1 - 0.35) x 679

0.65 x 679 = $441.35

Purchase price after you buy with your credit card : (1 - percentage decrease) x discounted price

(1 - 0.15) x  $441.35

Similarly,

∠k = 61°, as ∠k and ∠61° re vertically opposite to each other. Both will be equal.

From the linear pair;

∠h + ∠g = 180

∠h = 180 - 29

The evaluation of the given functions are as follows;

1. f(x) = 3 - x

g(x) = -2•x

Therefore;

g(fx) = -2 × f(x)

Which gives;

-2 × (3 - x) = -6 + 2•x = 2•x - 6

g(fx) = 2•x - 6

B. 2•x - 6

2. f(x) = 3 - x

g(x) = -2•x

f(g(x)) = 3 - (-2•x) = 3 + 2•x

f(g(x)) = 3 + 2•x

f(g(2)) = 3 + 2×2 = 7

The correct option is therefore;

C. 7

3. f(x) = 3 - x

g(x) = -2•x

Therefore;

g(fx) = 2•x - 6

g(f-1) = 2×(-1) - 6 = -8

C. -8

4. F(x) = 2•x - 1, G(x) = 3•x + 2, H(x) = x²

F(G(x)) = 2•(3•x + 2) - 1 = 6•x + 3

F(G(x)) - F(x) = 6•x + 3 - (2•x - 1) = 4•x + 4

A. 4•x + 4

5. F(x) = 2•x - 1, G(x) = 3•x + 2, H(x) = x²

G(H(x)) = 3•x² + 2

G(H(1)) = 3×1² + 2 = 5

A. 5

6. F(x) = 2•x - 1, G(x) = 3•x + 2, H(x) = x²

F(G(H(x))) = 2•(3•x² + 2) - 1 = 6•x² + 3

F(G(H(2))) = 6×2² + 3 = 27

B. 27

7. F(x) = 2•x - 1, G(x) = 3•x + 2, H(x) = x²

H(x + a) - H(x) = (x + a)² - x² = 2•a•x + a²

B. a² + 2•a•x

8. (H(x + a) - H(x))/a = (a² + 2•a•x)/a

(a² + 2•a•x)/a = a + 2•x = 2•x + a

A. 2•x + a

9. F(x) = 2•x - 1, G(x) = 3•x + 2, H(x) = x²

F(x) + G(x) + H(x) = 2•x - 1 + 3•x + 2 + x² = x² + 5•x + 1

C. x² + 5•x + 1

10. f(x) = 2•x² - 3•x + 1

f(3) - f(2) = 2×3² - 3×3 + 1 - (2×2² - 3×2 + 1) = 7

B. 7

11. G(x) = 5•x - 2

G^(-1)(x) = (G(x) + 2)/5

Which gives;

G^(-1)(x) = (x + 2)/5

A. (x + 2)/5

12. f(x) = 2/(x - 6)

The inverse is therefore;

(2/f(x)) + 6

The inverse of f(x) is therefore;

(2/x) + 6

13. g(x) = (5•x - 5)/4

(4•g(x) + 5)/5 = (4/5)•g(x) + 1

The inverse of g(x) is therefore;

Three angles make compose a triangle.

They'll be known as a°, b°, c°.

If we total everything up:

a° + b° + c = 180

The triangle's horizontal line may be drawn farther to the right, creating a new angle. Call this angle "d°" for short.

a° + b° Equals d°

Give this some values:

a° = 60° b° = 70°

c° = 50°

Do should be 130° since c and d create 180° with c° 50°.

Additionally, because:

A + B + C Equals 180, and C + D = 180.

Because the cremains in both cases are the same, a + b = d.

Any of these fit the bill.

Let's call this f° if you will just extend the triangle's horizontal line to the left.

So, b + c Equals f.

So, if a F Equals 120° since f = 60° and a + f = 180.

We established that b + c Equals f in this instance.

Let's now make the line longer and give it the name angle g°.

B being equal to 70°, the angle next to it is 110°.

Consequently, a + c = g.

All inner angles added together equal 180 degrees.

Additionally, the total of the other two inside angles is equal to the outer angles.

By elimination, the solution of the system of equations, x + y = 12 and x - y = 2, is (7 , 5).

A system of equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy all the equations.

There are three methods that can be used to solve system of equations.

1. Elimination

2. Substitution

3. Graphing

Using the elimination method, given two equations in x and y, a variable should be eliminated by adding/subtracting the two equations.

Adding the two equations will eliminate the variable y.

x + y = 12     (equation 1)

x  - y = 2    (equation 2)

2x + 0y = 14

x = 7

Substitute the value of x to any of the two equation and solve for y.
