Step-by-step explanation:

Answer:

y = 2x - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 2, thus

y = 2x + c ← is the partial equation

To find c substitute (3, 5) into the partial equation

5 = 6 + c ⇒ c = 5 - 6 = - 1

y = 2x - 1 ← equation of line

Answer:

(1,0)-------Increases------X=0-----Decreases to negative infinity

Step-by-step explanation:

Value of function f(x) = logx at axis (1,0) is zero.

A graph can be defined as a pictorial representation or a diagram that represents data or values.

The graph of the logarithmic function y=logx is shown.

The domain of function f(x) = logx is the set of all positive real numbers.

1. f(x)=logx domain of the logirthimic function is (0, ∞).

2. The range is the set of all real numbers.

3. The function is continuous and one-to-one.

4. The y-axis is the asymptote of the graph.

5. The graph intersects the x-axis at (1,0). That is, the x-intercept is 1.

Value of function f(x) = logx at axis (1,0)

⇒ f(x) = 0

Thus, value of function f(x) = logx at axis (1,0) is zero.

You would earn $637

Equation: (4,800x6.5%)+325

Step-by-step explanation:

6.5%= 0.065

So 4800 times 0.065 is 312.

Then you add 312 to the weekly salary of 325

325+312= 637

Answer:

The slope is 5/3

Step-by-step explanation:

Answer:

B) 15/8

Step-by-step explanation:

Use the SOH-CAH-TOA acronym:

• SOH: Sin(θ) = Opposite / Hypotenuse

• CAH: Cos(θ) = Adjacent / Hypotenuse

• TOA: Tan(θ) = Opposite / Adjacent

Tangent of A would be "opposite" over "adjacent". The side of the triangle opposite angle A would be 15, and the side adjacent to angle A would be 8 -- the value of tan(A) is 15/8.

Tan(A) cannot be 15/7, because 7 is the hypotenuse. Remember that the hypotenuse of a right triangle is the side opposite the 90° angle -- here, angle B is the 90° angle.

Answer:

67/18 is 3.72 as a decimal.

Step-by-step explanation:

I know this because, to turn a fraction into a decimal, you must divide the numerator by the denominator.

67 ÷ 18 = 3.72

Therefore, 3.72 is my answer.

Step-by-step explanation:

At the end of each year, its value is down to 79%, which is 0.79 times its value at the start of the year.  Keep this up for n years and the value is

V(n) = $20,000 (0.79)n,

where n is the number of years elapsed from when the value was $20,000.  Just plug in n=5 and n=8, evaluate, and get your 2 answers.

x=1160 HAVE A GREAT DAY!!! :D

Step-by-step explanation:

Okay! So, first you would set up a proportion

x/1740=2/3

Then you cross multiply

3x=3480

After that, you divide both sides of the equation by 3

x=1160

Answer:

  weight = 5, 6.5, 7.2, 9, 16

  cost = $2.50, $3.25, $3.60, $4.50, $8.00

Step-by-step explanation:

The first column tells you the cost is ...

  $2.50/(5 lb) = 0.50 $/lb

That is, each bottom number is half the top number, or each top number is double the bottom number.

The table is ...

  weight = 5, 6.5, 7.2, 9, 16

  cost = $2.50, $3.25, $3.60, $4.50, $8.00

Answer:

x=5

Step-by-step explanation:

Step 1: Flip the equation.

−2x−9=−19

Step 2: Add 9 to both sides.

−2x−9+9=−19+9

−2x=−10

Step 3: Divide both sides by -2.

Exact Form:

x = 9/17

Decimal Form:

x = 0.52941176…

Edit: "but what are the steps to get 9/17"

1. Move all terms containing x to the left side of the equation.

2. Divide each term by −17 and simplify.

Answer:

B and D

Step-by-step explanation:

The function is the relation between the sister's shoe size and her age, being age the independent variable x, and the shoe size the dependent variable y.

If we think this through, we'll find out that age is a discrete variable, and shoe size too. Discrete variable refers to those variable that only admit whole numbers, they don't admit decimal numbers. So, in this case, both variables aren't represented by decimal values. So, the relationship is discrete function, punctual data.

Similarly, the function must be restricted to positive integers, because, as we already said, the variable only admit discrete values and we have to add that only should admit positive discrete values, because age cannot be negative, it wouldn't make sense, also shoe size cannot be negative. In this context, negative numbers don't make any sense.

Answer:

1.72r²

Step-by-step explanation:

total Rectangle area = 4r*2r = 8r²

total circles area = 2(π r²) = 2*3.14*r² = 6.28r²

then:

the area of the shaded region:

= 8r² - 6.28r²

= (8-6.28)r²

= 1.72r²

Answer:

2r²(4 - π)

Step-by-step explanation:

The shaded area (A) is calculated as

A = area of rectangle - area of 2 circles

The rectangle has a length of 4r and a width of 2r , then

A = (4r × 2r) - (2πr²)

   = 8r² - 2πr² ← factor out 2r² from each term

    = 2r²(4 - π)

Answer:

5. a^3 + b^3 = (a+b)^3 - 3ab(a+b)

Step-by-step explanation:

(a+b)^3

= (a+b) (a+b) (a+b)

={(a+b) (a+b)} (a+b)

={a(a+b) + b(a+b)} (a+b)

=(a^2 + ab + ab + b^2) (a+b)

=(a^2 + b^2 + 2ab) (a+b)

=a^2(a+b) + b^2(a+b) + 2ab(a+b)

=a^3 + a^2b + ab^2 + b^3 + 2a^2b + 2ab^2

=a^3 + b^3 + 3a^2b + 3ab^2

=a^3 + b^3 + 3ab(a+b)

(a+b)^3 = a^3 + b^3 + 3ab(a+b)

(a+b)^3 - 3ab(a+b) = a^3 + b^3

a^3 + b^3 = (a+b)^3 - 3ab(a+b)

Answer:

I am just giving the expansion, so that you can substitute the values and solve it

Answer:

I would say b

Step-by-step explanation:

I choose b because the question is linear and also non linear it only told us the distance which is 500x and no time but is saying as a function of time

C. The function is linear.

The given function is y = 500x, where x represents the time and y represents the distance from Portland. In this function, y is directly proportional to x, meaning that for every unit increase in x, y increases by a constant amount of 500.

Since the function is of the form y = mx, where m (in this case, 500) is the constant of proportionality, the function is linear.

Therefore, the correct answer is:

C. The function is linear.
