Answer:

35x²- 18x -8

Step-by-step explanation:

5x × 7x= 35x²

5x × 2= 10x

-4 × 7x= -28x

-4 × 2= -8

*combine like terms

35x² + 10x -28x -8

10x - 28x= -18x

35x²- 18x -8

Answer:

1. f(x) = 3x + 7

2. [tex]f(x) = -\dfrac12x + 2[/tex]

3. f(x) = x + 5

4. f(x) = -2x - 5

5. [tex]f(x) = -\dfrac32 x + 2[/tex]

Step-by-step explanation:

Rearrange all the equations to make y the subject,
then substitute f(x) for y:

1.   y - 3x = 7

Add 3x to both sides:

⇒ y = 3x + 7

⇒ f(x) = 3x + 7

2.   2x + 4y = 8

Subtract 2x from both sides:

⇒ 4y = -2x + 8

Divide both sides by 4:

⇒ [tex]y = -\dfrac12x + 2[/tex]

⇒ [tex]f(x) = -\dfrac12x + 2[/tex]

3.   -x + y = 5

Add x to both sides:

⇒ y = x + 5

⇒ f(x) = x + 5

4. y + 5 = -2x

Subtract 5 from both sides:

⇒ y = -2x - 5

⇒ f(x) = -2x - 5

5.   3x + 2y - 4 = 0

Subtract 3x from both sides:

⇒ 2y - 4 = -3x

Add 4 to both sides:

⇒ 2y = -3x + 4

Divide both sides by 2;

⇒ [tex]y = -\dfrac32 x + 2[/tex]

⇒ [tex]f(x) = -\dfrac32 x + 2[/tex]

solutions:        greater than, less than, equals to:

Step-by-step explanation:

yes, it would be an isoceles triangle (with 2 sides being equally long).

it would be a reissue high and narrow triangle, with the very short side (2) connecting the 2 sides of 8.

in general, 3 lines can only make a triangle, if the sum of lengths of any pair of these lines is always longer than the third line.

in our case :

8+2 > 8 true

8+8 > 2 true

so, yes, they can be a triangle.

example for 3 sides not making a triangle :

2, 3, 6

as

2+3 < 6

Answer:

B. The equations create the same line

Step-by-step explanation:

A system of two linear equations have either 0, 1 or infinite solutions.

Since you have 2 solutions, there have to be infinitely many more. That means you have written the same line twice. The solution is B.

Alternatively, you can think that given two points, there is one and only one line that passes through both.

Answer:

m<G = 55°

Step-by-step explanation:

m<G = (1/2)[m(arc)LE - m(arc)HF]

m<G = (1/2)[150° - 40°)

m<G = 110°/2

m<G = 55°

1 cube = 6 Faces

2 cubes = 10 Faces

7 cubes = 36 Faces

2÷7 = 3 × 10 = 30 + 6 = 36

The Answer is 36

Answer:

2 cubes = 10 faces

3 cubes = 14 faces

4 cubes = 18 faces

5 cubes = 22 faces

6 cubes = 26 faces

7 cubes = 30 faces

10 faces = 2 cubes

14 faces = 3 cubes

18 faces = 4 cubes

Step-by-step explanation:

We know that 1 cube shows 6 faces, and 2 cubes shows 10 faces. With 3 cubes, it shows 14 faces.

With this pattern, we can conclude that

f(x) = 2 + 4x

f(x) is a function for where f is the value of faces and x is the amount of cubes connected.

To find the amount of faces for the cubes used

f(2) = 2 + 4(2) = 2 + 8 = 10

f(3) = 2 + 4(3) = 2 + 12 = 14

f(4) = 2 + 4(4) = 2 + 16 = 18

f(5) = 2 + 4(5) = 2 + 20 = 22

f(6) = 2 + 4(6) = 2 + 24 = 26

f(7) = 2 + 4(7) = 2 + 28 = 30

For the amount of cubes used given the amount of faces

10 = 2 + 4x

-2   -2

8/4 = 4x/4

2 = x

x= 2

14 = 2 + 4x

-2    -2

12/4 = 4x/4

3 = x

x = 3

18 = 2 + 4x

-2   -2

16/4 = 4x/4

4 = x

x = 4

Answer:

[tex]-\frac{13}{4}[/tex]

Step-by-step explanation:

r = 4x + 6y

11 = 4x + (6 x 4)

11 = 4x + 24

(im gonna flip it around because it looks better for me, you dont have to)

4x + 24 = 11  _(minus 24 from both sides)

4x = -13  _(divide both sides by 4)

x = [tex]-\frac{13}{4}[/tex]
