-x + 2 + 5x= 10 (x - 4) solve for x

Answers

Answer 1

Answer:

7

Step-by-step explanation:

-x+2+5x=10(x-4)

4x+2=10x-40

2+40=10x-4x

42=6x

42/6=6x/6

7=x

Answer 2

Answer:

x = 7

Step-by-step explanation:

-x + 2 + 5x = 10 (x - 4)

=> 4x + 2 = 10x - 40

=> 4x - 10x = -40 - 2

=> -6x = -42

=> 6x = 42

=> x = 42/6

=> x = 7

HELP ASAP ...........

Answers

Answer:

A

Step-by-step explanation:

Given

y - 2x - 8 = 0 ( add 2x + 8 to both sides )

y = 2x + 8 → (1)

y² + 8x = 0 → (2)

Substitute y = 2x + 8 into (2)

(2x + 8)² + 8x = 0 ← expand left side using FOIL and simplify

4x² + 32x + 64 + 8x = 0

4x² + 40x + 64 = 0 ( divide through by 4 )

x² + 10x + 16 = 0 ← in standard form

(x + 8)(x + 2) = 0 ← in factored form

x + 8 = 0 ⇒ x = - 8

x + 2 = 0 ⇒ x = - 2

Substitute these values into (1) for corresponding values of y

x = - 8 : y = 2(- 8) + 8 = - 16 + 8 = - 8 ⇒ P (- 8, - 8)

x = - 2 : y = 2(- 2) + 8 = - 4 + 8 = 4 ⇒ Q (- 2, 4 )

Calculate the length of PQ using the distance formula

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

with (x₁, y₁ ) = P (- 8, - 8) and (x₂, y₂ ) = Q (- 2, 4 )

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

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

       = [tex]\sqrt{6^2+12^2}[/tex]

       = [tex]\sqrt{36+144}[/tex]

       = [tex]\sqrt{180}[/tex]

       = [tex]\sqrt{36(5)}[/tex]

The first side of a triangle is 4m shorter than the second side. The third side 3 times as long as the first side. The perimeter is 24m. Find the length of each side

Answers

Answer:

1st side= 4m

2nd side= 8m

3rd side= 12m

Step-by-step explanation:

Let the first, second and third side of the triangle be a, b and c meters respectively.

a= b -4 -----(1)

c= 3a -----(2)

Perimeter of triangle

= a +b +c

= 24

a +b +c= 24 -----(3)

From (1): b= a +4 -----(4)

Subst. (2) and (4) into (3):

a +(a +4) +3a= 24

3a +a +a +4= 24

5a +4= 24

5a= 24 -4

5a= 20

Divide both sides by 5:

a= 20 ÷5

a= 4

Substitute a= 4 into (4):

b= 4 +4

b= 8

Substitute a= 4 into (2):

c= 3(4)

c= 12

Thus, the lengths of the first, second, and third side of the triangle are 4m, 8m and 12m respectively.

The length of a rectangle is 5cm more then the width. the perimeter of the rectangle is 38cm.find the length and width of the rectangle?

Answers

Answer:

Length - 12

Width - 7

Step-by-step explanation:

38 = 2((5+x) + x)

38 = 10 +4x

28=4x

x=7

7+5=12

Given : The length of a rectangle is 5cm more then the width. The perimeter of the rectangle is 38cm. Find the length and width of the rectangle?

Solution : According to the question, here we are given that the length if the rectangle is 5m more than its breadth and so the perimeter of the rectangle is 38cm. So, for this let's check the steps below

Let's assume the breadth be B

So, as we got that length is 5cm more than Breadth which is B + 5cm

Perimeter is 38cm

Perimeter = 2(Length + Breadth)

Perimeter = 2(B + 5cm + B)

38cm = 2(2B + 5cm)

38cm/2 = 2B + 5cm

19cm - 5cm = 2B

2B = 14cm

B = 7cm

Finding Length

Length = B + 5cm = 7cm + 5cm = 12cm

Finding Breadth

Breadth(Width) = B = 7cm

Therefore, Width is 7cm whereas Length is 12cm

The total cost of a pizza and 3 drinks is $19. The price of the pizza is $10 and each drink is the same price, d. 6) Which model represents the situation?

Answers

The total cost of pizza and drinks, is an illustration of a linear function.

The model that represents the situation is: [tex]\mathbf{10 + 3d = 19}[/tex]

The given parameters are:

[tex]\mathbf{Total =19}[/tex]

[tex]\mathbf{1\ pizza =10}[/tex]

[tex]\mathbf{1\ drink =d}[/tex]

The cost of 3 drinks will be 3d

The total cost would then be:

[tex]\mathbf{Total = 10 + 3d}[/tex]

Substitute 19 for Total

[tex]\mathbf{10 + 3d = 19}[/tex]

Rewrite the above equation as:

[tex]\mathbf{3d + 10 = 19}[/tex]

Hence, the model that represents the situation is: [tex]\mathbf{10 + 3d = 19}[/tex]

Answers

Answer:

f(g(x)) = 2x - 5

Step-by-step explanation:

Given:

f(x) = 2x + 1

and

g(x) = x - 3

Find the composite function f(g(x)), substitute g(x) with its value:

f(g(x)) = f(x - 3) = 2(x - 3) + 1 = 2x - 6 + 1 = 2x - 5

Answer:

It is given

4x+3y=24

We can also write it as

3y=24−4x

 y=324−4x

Substituting x=0 in the given equation

 y=324−4(0)

 So we get 

 y=324

 By division 

 y=8 

 Substituting x=3 in the given equation 

 y=324−4(3)

 So we get

All parallelograms are not a kite.
