Answer:

I added the graph

Answer:

x = 4

Step-by-step explanation:

5x -7 + 2x = 4x + 5

Combine like terms

5x + 2x -7 = 4x + 5

7x - 7 = 4x + 5

Combine like terms again

-4x + 7x - 7 = 4x - 4x + 5

3x - 7 = 5

3x = 5 + 7

3x = 12

Divide by 3 both sides

3x/3 = 12/3

x = 4

Answer:

b. -84

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Equality Properties

Algebra I

Step-by-step explanation:

Step 1: Define

[tex]\displaystyle \frac{a}{-7} - 7 = 5[/tex]

Step 2: Solve for a

Step 3: Check

Plug in a into the original equation to verify it's a solution.

Here we see that 5 does indeed equal 5.

∴ a = -84 is the solution to the equation.

Answer:

-1=(30+x)÷6

-6=30+x

-6-30=x

x=-36

Answer:

[tex]43.87^{\circ}[/tex]

Step-by-step explanation:

We are given that

Height of mountain=350 m

Distance  from the tree to the skier=505 m

We have to find the angle of depression from where the skier is standing to the base of the tree.

In triangle ABC

[tex]\frac{AB}{AC}=sin\theta[/tex]

By using the formula

[tex]\frac{Perpendicular\;side}{Hypotenuse}=sin\theta[/tex]

[tex]\frac{350}{505}=sin\theta[/tex]

[tex]sin^{-1}(\frac{350}{505})=\theta[/tex]

[tex]\theta=43.87^{\circ}[/tex]

Hence, the angle of depression from where the skier is standing to the base of the tree=[tex]43.87^{\circ}[/tex]

Answer: 30 player on the team

Step-by-step explanation:

If 9 players = 30% of the team then 3 = 10% of the team. With this information you can multiply 10 x 10 to get 100(%) and then multiply 3 x 10 to get 30(players). This may not be how you are supposed to solve this problem but oh well.

Answer:

r = $105.6

Step-by-step explanation:

Given,

Amount paid by Trevor for 4 nights = $528

Rate per day = r

Now,

We know that a 4-night stay in the hotel means 5 days to stay at MGM Grand.

Now,

Amount paid = Number of days x Rate per day

$528 = 5 r

[tex]r = \frac{528}{5}[/tex]

r = $105.6

Hence, Trevor pays $105.6 to stay at the MGM Grand Hotel in Las Vegas for four nights.

Answer:

3.5

Step-by-step explanation:

5(6-x)=12.5

(5*6)-(5*x)=12.5

30-5x=12.5

subtract 30 from each side:

-5x=-17.5

divide -5 from each side:

x=3.5

Answer: 3x-8

Step-by-step explanation:

The algebraic factor of the given quadratic equation 9x² - 18x + 8 is 3x - 4 thus option (A) is correct.

An algebraic factor is the multiplication of two algebraic terms.

If we divide an algebraic factor by a factor that is available inside then the remainder after the division will be zero.

As per the given quadratic equation,

9x² - 18x + 8

⇒ 9x² - 12x - 6x + 8

⇒ 3x(3x - 4) - 2(3x - 4)

⇒(3x - 4)(3x - 2)

Hence "The algebraic factor of the given quadratic equation 9x² - 18x + 8 is 3x - 4".
