Step-by-Step Explanation:

First of all, Cross Multiplying:

[tex]5(5x - 8) = 3(11x - 9)[/tex]

Now expanding the parentheses,

[tex]25x - 40 = 33x - 27[/tex]

Shifting 33x to the Left hand side of the equation.

[tex]25x - 33x = - 27 + 40[/tex]

This is Equal to:

[tex] - 8x = 13[/tex]

And dividing -8 both sides,

[tex]x = \dfrac{ - 13}{8} [/tex]

Function is a relation that the domain doesn't have the same/repetitive value in a single set.

Some set of relations have repetitive domain

For example, {(1,1),(1,2)} This is NOT a function.

But {(1,1),(2,1)} is a function because there are no repetitive domains.

Therefore the answers are first choice, second choice and fifth choice.

Answer:

the slope would be y=20x+10

it means that for every 20 minutes he drives he is 10 miles closer to his job

(1) Recall the angle sum identity for cosine:

cos(x + y) = cos(x) cos(y) - sin(x) sin(y)

So

cos(π/3) cos(5π/6) - sin(π/3) sin(5π/6) = cos(π/3 + 5π/6)

= cos(7π/6)

= -√(3)/2

(2) Recall the half-angle identity:

cos²(x) = (1 + cos(2x))/2

Since π/2 < 7π/12 < π, you should expect cos(7π/12) < 0. So solving for cos(x) above, we have

cos(x) = -√[(1 + cos(2x))/2]

Then

cos(7π/12) = -√[(1 + cos(7π/6))/2]

= -√[(1 - √(3)/2)/2]

= -√[1/2 - √(3)/4]

You could stop there, or continue and try to de-nest the radicals to end up with

= (√(2) - √(6))/4

(3) Recall the angle sum formula for tangent:

tan(x - y) = (tan(x) - tan(y))/(1 + tan(x) tan(y))

Then

(tan(122°) - tan(32°))/(1 + tan(122°) tan(32°)) = tan(122° - 32°)

= tan(90°)

which is undefined, since tan(x) = sin(x)/cos(x), and cos(90°) = 0.

(4) Recall the double angle identity for sine:

sin(2x) = 2 sin(x) cos(x)

Then

2 sin(15°) cos(15°) = sin(30°)

= 1/2

(5) Use the double angle identity for cosine:

cos(2x) = 2 cos²(x) - 1

Then

12 cos²(θ) - 6 = 6 (2 cos²(θ) - 1)

= 6 cos(2θ)

(6) Use the sine double angle identity mentioned in (4):

7 cos(4x) sin(4x) = 7/2 (2 cos(4x) sin(4x))

= 7/2 sin(8x)

Given that two golfers completed one round of golf.

It is stated that the first golfer had a score of +6 and the second golfer had a score of -3.

It is clear that the first golfer is 6 over par, while the second golfer is under 3.

Thus, the equation becomes:

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

adding -3 to both sides

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

simplify

[tex]x = 9[/tex]

Thus, the second golfer has taken 9 more shorts.

When we talk about credit, it means:

Credit = +

When we talk about debt, it means:

Debit = -

Thus,

Credit = +84

Debt = -29

Balance = 84 + (-29)

              = 84 - 29

               = 55

Thus, the balance is: 55

Step-by-step explanation:

Here, we want to know if the set of given sides will form a triangle

Mathematically, for a triangle to be formed, the sum of two sides must be greater than the third side

If we have a, b and c as sides of a triangle, then mathematically (

a + b > c

a + c > b

and b + c > a

If at any point, these does not work, then we can’t have a triangle

Let us consider the lengths one after the other

We proceed as follows;

2 9 12

Since 2 + 9 is not greater than 12, we cannot have a triangle

3 , 5, 8

Since 3 + 5 equals 8 and not greater than it, we cannot have a triangle

10 , 12 , 15

This forms a triangle

10 + 12 > 15

10 + 15 > 12

12 + 15 > 10

Lastly;

4 , 4 , 7

Since ;

4 + 4 > 7

and

4 + 7 > 4

we have a triangle

Answer:  Most likely, the value of w is 5 units.

Step-by-step explanation: P = 2L + 2w

If the perimeter is 28, the side lengths must be less than 14, otherwise there is no width, just two lines on top of one another.

If the width is 7, then all four sides would be 7 units, and that would create a square-- which is a type of rectangle-- but probably not what this question is about.

A width of 5 units makes sense, 2w would be 10, leaving 28-10 = 18 to be divided by 2 for lengths of 9

The rectangle would have a width of 5 units and a length of 9 units.

Answer:

1. Andre wants to buy a bike that has a price tag of $125. What was the wholesale cost of this bike?    $ 96.15

2. If the bike is discounted by 20%, how much will Andre pay (before tax)?  

                        $ 100

                                       I hope this helped <33 !

The wholesale cost of the bikes was $96.15 and the price that Andre can buy it for after the discount is $100.

The cost of the bikes after the markup is $125. The markup was 30%. Assuming the wholesale price is x, the expression would be:

x + (x × 30%) = 125

x + 0.3x = 125

1.3x = 125

x = 125/1.3

x = $96.15

If Andre want to buy the bike at a discounted price of 20%, the price would be:

= Selling price x (1 - Discount rate)

= 125 x (1 - 20%)

= 125 x 0.8

= $100

In conclusion, the wholesale price was $96.15 and the amount Andre pays is $100.
