Which number line model represents the expression -2+(-7)?
Khan academy help!!!!!

Answer:

Option (A)

Step-by-step explanation:

Te given equation is,

-qx + p = r

Toe find the value of x,

By subtracting  p from both the sides of the equation.

-qx + p - q = r - q

-qx = r - q

By dividing the whole equation by (-q),

[tex]\frac{-qx}{(-q)}=\frac{r-p}{-q}[/tex]

x = [tex]-\frac{r-p}{q}[/tex]

x = [tex]\frac{p-r}{q}[/tex]

Therefore, Option (A) will be the answer.

Answer:

k = 0

Step-by-step explanation:

Step 1:

7k - 7 ( 2 - 6k ) = - 8k - 14   Equation

Step 2:

7k - 14 + 42k = - 8k - 14   Multiply

Step 3:

- 14 + 49k = - 8k - 14   Add

Step 4:

- 14 + 57k = - 14     Add 8k on both sides

Step 5:

57k = 0   Add 14 on both sides

Answer:

k = 0

The required width of Amy's kitchen would be 8 ft.

Given that,
The measurement of Amy's rectangular kitchen is 12 feet. If the area of the room is at least 96 square feet, To determine the least width the room could have.

The rectangle is a four-sided geometric object with equal-length opposites and 90° angles on each side.

Here,
let the width be x,
according to the question,
area of the kitchen = 96
length × width = 96
12 × x = 96
x = 96 / 12
x = 8

Thus, the required width of Amy's kitchen would be 8 ft.

Answer:

23.4 years

Step-by-step explanation:

The exponential growth model is

A = P(1 + r)^5t, where r is the annual growth rate as a decimal fraction.

If the original number (P) is to double, then this model becomes

2P = P(1 + 0.03)^t, or 2 = 1.03^t.  Solve this for t by taking the log of both sides:

log 2 = t*log 1.03, or

     0.30103

t = --------------- = 23.4 years

Step-by-step explanation:

Calculate AC and AB using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = A(1,8) and (x₂, y₂ ) = C(4,2)

AC = [tex]\sqrt{(4-1)^2+(2-8)^2}[/tex]

      = [tex]\sqrt{3^2+(-6)^2}[/tex]

       = [tex]\sqrt{9+36}[/tex]

       = [tex]\sqrt{45}[/tex] = [tex]\sqrt{9(5)}[/tex] = 3[tex]\sqrt{5}[/tex]

Repeat with

(x₁, y₁ ) = A(1, 8) and (x₂, y₂ ) = B(2, 6)

AB = [tex]\sqrt{(2-1)^2+(6-8)^2}[/tex]

      = [tex]\sqrt{1^2+(-2)^2}[/tex]

       = [tex]\sqrt{1+4}[/tex]

       = [tex]\sqrt{5}[/tex]

So AB = [tex]\sqrt{5}[/tex] and AC = 3[tex]\sqrt{5}[/tex]

Thus

AC = 3AB

Answer:

Proven below

Step-by-step explanation:

Distance Between Points in the Plane

Given two points A(x,y) and B(w,z), the distance between them is:

[tex]d=\sqrt{(w-x)^2+(z-y)^2}[/tex]

Let's calculate the distance AC, where A(1,8) and C(4,2):

[tex]d_{AC}=\sqrt{(4-1)^2+(2-8)^2}[/tex]

[tex]d_{AC}=\sqrt{3^2+(-6)^2}[/tex]

[tex]d_{AC}=\sqrt{9+36}=\sqrt{45}[/tex]

Since 45=9*5:

[tex]d_{AC}=\sqrt{9*5}=3\sqrt{5}[/tex]

Calculate the distance AB, where A(1,8) and B(2,6)

[tex]d_{AB}=\sqrt{(2-1)^2+(6-8)^2}[/tex]

[tex]d_{AB}=\sqrt{1^2+(-2)^2}[/tex]

[tex]d_{AB}=\sqrt{1+4}=\sqrt{5}[/tex]

It follows that:

[tex]d_{AC}=3d_{AB}[/tex]

Answer: 6

Step-by-step explanation:

2(x-3)+7=13

simplify both sides of the equation

(2)(x) + (2)(-3) + 7 = 13 (distribute)

2x + -6 + 7 = 13

(2x) + (-6+7) = 13 (combine like terms)

2x + 1 = 13

subtract 1 from both sides

2x + 1 - 1 = 13 - 1

2x = 12

Divide both sides by two

2x/2 = 12/2

x = 6
