Answer:

Step-by-step explanation:

The sum of all the internal angles of a convex octagon must equal 1080.

You'll want to add all the angles together and then solve.

[tex](x+55)+(3x+20)+4x+(4x-10)+(6x-55)+(3x+52)+3x+(2x+30) = 1080[/tex]

Just combine like terms and then solve for x.

Answer:

(3,12)

Step-by-step explanation:

y = 3x + 3

y = 6x -6

x = 3

y = 12

= (3,12)

Answer:

All you have to do, is find an x that if used in both equations, both equal the same y.

3 x 3 + 3 = 12

6 x 3 - 6 = 12

So, the only thing here is (3, 12)

Step 3: Solve for y

y = -2x² - 8x + 3

#First, find the x coordinate first by using the formula of -b/2a

x = -b/2a = -(-8)/2(-2) = 8/-4 = -2

#After getting the x, find the y

y = -2(-2)² - 8(-2) + 3

y = -2×4 +16 + 3

y = -8 + 16 + 3

y = 11

So the vertex is

(-2,11)

════════════════════

Answer:

the vertex is (-2, 11)

Step-by-step explanation:

F(x) = -2X^2 - 8X + 3 can be rewritten as -2(x^2 + 4x) + 3.

We complete the square of x^2 + 4x, obtaining x^2 + 4x + 4 - 4 = (x + 2)^2 - 4

and then we substitute this last result into F(x) = -2(x^2 + 4x) + 3:

F(x) = -2[ (x + 2)^2 - 4 ] + 3, which simplifies to:

F(x) = -2(x + 2)^2 + 8 + 3, or F(x) = -2(x + 2)^2 + 11

Comparing this to the vertex equation (x + h)^2 + k, we see that h must be -2 and k must be 11.  

Thus, the vertex is (-2, 11).

The appropriate rephrase statement to proof the Pythagorean theorem is

In ΔABC , if ∠B = 90°, then AB² + BC² = AC²

Pythagoras's theorem is used to calculate the sides of a right angle triangle. The formula is represented as follows

where

c = hypotenuse

a and b are either adjacent or opposite sides of the triangle.

A right angle triangle is a triangle that has one angle as 90°. Therefore, from the triangle below, the appropriate rephrase statement to proof Pythagoras theorem is as follows:

Answer:

x=1

Step-by-step explanation:

3x+2(4x-4) = 3

3x+8x-8 = 3

11x-8 = 3

11x = 11

x = 11/11 = 1

The solution for x in the expression 3x + 2 (4x- 4) = 3 is,

⇒ x = 1

The given expression is,

⇒ 3x + 2 (4x- 4) = 3

We can simplify by apply distributive property and combine like term,

⇒ 3x + 2 (4x- 4) = 3

Apply distributive property,

⇒ 3x + 8x - 8 = 3

Combine like term,

⇒ 11x - 8 = 3

Add 8 both side,

⇒ 11x = 3 + 8

⇒ 11x = 11

Divide by 11,

⇒ x = 11 / 11

⇒ x = 1

Therefore, The solution for x in the expression 3x + 2 (4x- 4) = 3 is,

⇒ x = 1

Answer: 0.907

Step-by-step explanation:

The average rate of change in a function from x= a to x = b is given by :-

[tex]\dfrac{f(b)-f(a)}{b-a}[/tex]

Given: [tex]S(x)=573-133(0.987)^x[/tex]

Then, the average rate of change of the SAT score for students with household incomes ranging from $40,000 to $60,000 per year will be :

[tex]\dfrac{S(60)-S(40)}{60-40}=\dfrac{573-133(0.987)^{60}-573-133(0.987)^{40}}{20}\\\\=\dfrac{512.34-494.20}{20}\\\\=\dfrac{18.14}{20}\\\\=0.907[/tex]

Step-by-step explanation:

The inverse relationship implies the following equation.

[tex]t=\frac{k}{T}[/tex]

where k is a constant.

You are given a t and T that go together, so

[tex]2=\frac{k}{75}[/tex]

This implies that k=150.  Now you know that the relationship is

[tex]t=\frac{150}{T}[/tex]

Now substitute 80 for T to get the answer.

[tex]t=\frac{150}{80}=\frac{15}{8}[/tex][tex]t=\frac{150}{80}=\frac{15}{8}[/tex]

It takes an ice cube of the same size to melt in 80f water 15/8 minutes.

We have given,

The time t  for am ice cube to melt. is inversely proportional to the

temperature T of the water in the ice cube is placed.

The inverse relationship implies the following equation.

[tex]t=\frac{k}{T}[/tex]

Where k is a constant.

You have given a  t and T that go together, so

[tex]2=\frac{k}{75}[/tex]

This implies that k=150.

Now you know that the relationship is

Answer:

x = 6.6, y = -6.8

Step-by-step explanation:

Subtract  3 x  from both sides of the equation.

y = 13 - 3x

4x + 3y = 6

Replace all occurrences of  y  with  13  −  3 x  in each equation.

-5x + 39 = 6

y = 13 - 3x

Solve for  x  in the first equation.

x = [tex]\frac{33}{5}[/tex] or 6.6

Replace all occurrences of  x  with 6.6  in each equation.

y = [tex]-\frac{34}{5}[/tex] or - 6.8
