Answer:

y - 7 = 5(x + 4)

Step-by-step explanation:

Point-slope form: y - y₁ = m(x - x₁)

(x₁,y₁) = (-4,7)

I am assuming your slope is 5.

m = slope = 5

Plugging these in, we have

y - 7 = 5(x-(-4))

Simplifying,

y - 7 = 5(x + 4)

Answer:

C [tex]f(x) = \frac{x}{(x+1)(x-2)}[/tex]

Step-by-step explanation:

Ok done. Thank to me :>

The values of x at wich F(x) has local minimums are x = -2 and x = 4, and the local minimums are:

A local maximum is a point on the graph of the function, such that in a close vicinity it is the maximum value there. So, on an interval (a, b) a local maximum would be F(c) such that:

c ∈ (a, b)

F(c) ≥ F(x) for ∀ x ∈ [a, b]

A local minimum is kinda the same, but it must meet the condition:

c ∈ (a, b)

F(c) ≤ F(x) for ∀ x ∈ [a, b]

A) We can see two local minimums, we need to identify at which values of x do they happen.

The first local minimum happens at x = -2

The second local minimum happens at x = 4.

B) The local minimums are given by F(-2) and F(4), in this case, the local minimums are:

If their total taxes due are $6,847.50, their taxable income is: $56,152.2, marginal rate is 22% and the effective tax rate is 10.87%.

a. Taxable income:

Taxable income=Gross income - Total taxes due

Taxable income=$63,000-$6,847.50

Taxable income=$56,152.5

b. The marginal tax rate for taxable income  under the income bracket of of $40,526 to $86,375 is 22%.

c. Effective tax rate:

Effective tax rate = Total taxes due/ Taxable income×100

Effective tax rate =$6,847.50/$56,152.5×100

Effective tax rate =10.869%

Effective tax rate =10.87% (Approximately)

Inconclusion if their total taxes due are $6,847.50, their taxable income is: $56,152.2, marginal rate is 22% and the effective tax rate is 10.87%.

Answer:

c=-2.5s

Step-by-step explanation:

The equation modeling the change in elevation c after s seconds is

c = -2.5s

Given,

A mountain climber descends a cliff at a rate of 2.5 ft/second.

We need to write an equation modeling the change in elevation c after s seconds.

Elevation means going up so we take it as a positive distance.

Descent means going down so we take it as a negative distance.

Find the rate at which the climber descents.

2.5 ft = 1 second

Find the equation that represents the descents c in seconds.

We have,

2.5 ft = 1 second

So,

s x 2.5 ft = s x 1 seconds

2.5 s ft = s seconds

This means,

In s seconds we will have a 2.5s distance descended.

We can write this as an equation:

c = change in elevation

c = - 2.5s

Thus the equation modeling the change in elevation c after s seconds is

c = -2.5s

Answer:

1/9 is smaller than 1/6, so it takes more amounts of 1/9 to make make a fraction equal to 1/3

It takes more 1/9 than 1/6 to make a fraction equivalent to 1/3.

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.

To make a fraction equivalent to 1/3, we need to multiply both the numerator and the denominator by the same non-zero constant. Let's call this constant "x". Therefore, the equivalent fractions are:

1/3 = (x1)/(x3)

To compare how many 1/9s and 1/6s are needed to create this fraction, we need to find the value of "x" that will make the denominators of 1/9 and 1/6 equal to the denominator of 1/3, which is 3.

For 1/9, we can find x as follows:

1/9 = (x1)/(x9)

Multiplying both sides by 3, we get:

3/9 = (x3)/(x9)

Simplifying, we get:

1/3 = x/9

Multiplying both sides by 9, we get,

x = 3

Therefore, to make a fraction equivalent to 1/3 using 1/9, we need to multiply both the numerator and denominator by 3.

Now let's look at 1/6. We can find x as follows:

1/6 = (x1)/(x6)

Multiplying both sides by 2, we get:

2/12 = (x2)/(x12)

Simplifying, we get:

1/6 = x/12

Multiplying both sides by 12, we get:

x = 2

Therefore, to make a fraction equivalent to 1/3 using 1/6, we need to multiply both the numerator and denominator by 2.
