Answer:

W1=0.875.

W2= -1.14

Step-by-step explanation:

(8w-7)(7w+8)

8w(7w+8)-7(7w+8)

56w^2+64w-49w-56

56w^2+15w-56

Solve it by quadratic equation

a=-b+-√(b^2-4ac)/2a

Substitute the values

And you will get 2 answers

a=-56

b=15

c=56

15.5

(Computer won't do fractions so 15.5 out of 10 or 15.5 in decimal form)

Answer:

= (10-3) ÷ (10-1) = 7 ÷9 = 7/9

Step-by-step explanation:

As they are parallel, their slopes are the same. So if we find slope of line j we find slope of line k when we have two points of one line like (x1 , y1) and (x2 , y2) the slope of that line is (y2-y1) ÷ (x2-x1)

3/4 (6x + 1) - 3x = 1/4 (2x - 1) . The purpose of this question is to solve for x.

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

Given that:

When calculating algebraic expression, we take note of integers in bracket first, then we collect the like terms in order to find the value of x.

[tex]\mathbf{\dfrac{3}{4} (6x + 1) - 3x =\dfrac{1}{4} (2x - 1) }[/tex]

Let's multiply both sides by 4 to eliminate the fraction.

[tex]\mathbf{(\dfrac{3}{4} \times 4) (6x + 1) - 3x =(\dfrac{1}{4} \times 4 ) (2x - 1) }[/tex]

[tex]\mathbf{(3) (6x + 1) - 3x =(1 ) (2x - 1) }[/tex]

18x + 3  - 3x = 2x - 1  

18x - 3x + 3 = 2x - 1

15x + 3 = 2x - 1

15x - 2x = - 3 - 1

13x = - 4

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

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

Answer:

12

Step-by-step explanation:

zeros are the x-intercepts of any function. to find the x-intercept of this given function, we have to set y equal to 0.

0= -1/2x+6

-6=-1/2x

12=x

x=12

the x-intercept is (12,0), meaning 12 is the zero of this function.

Answer:

Step-by-step explanation:

It is helpful to realize that the exterior angle is equal to the sum of the remote interior angles:

  146° = (5y+3)° +(4y+8)°

  135 = 9y . . . . . . . . . . . . . . divide by °, subtract 11

  15 = y . . . . . . . . . divide by 9

∠abc = (4y+8)° = (4·15 +8)° = 68°

∠bac = (5y+3)° = (5·15 +3)° = 78°

∠acb = 180° -146° = 34°

Answer:

12 units

Step-by-step explanation:

Each side of the triangle is 1 unit. When putting 10 triangles together in figure 10, there will be 12 sides on the perimeter. Therefore, your answer is 12 units.

Answer:

The answer is 72

Answer:

A)  linear

Step-by-step explanation:

Let the gallons of paint be represented by g, and the area by x.

Each gallon of paint covers 400 square feet of surface area.

⇒ x = 400g

So that; when g = 1,

x = 400 square feet

when g = 5,

x = 400 x 5

  = 2000 square feet

when g = 10,

x = 400 x 10

 = 4000 square feet

The relationship between the variables is linear because g and x increases at a constant rate.

Answer:

[tex]150 + 75h > 600[/tex]

Step-by-step explanation:

The inequality that can be used to determine h is shown below:-

As per the given situation,  it is mentioned that a plumber could earns $50 for a repair job, so for three jobs he earned $150 as a total amount

Now

We presume h be the number of hours

Also he earns additional $75 per hour worked so $75

Total amount is $150 + $75h)

The total amount is more than $600

So, the inequality equation is as given below:

[tex]150 + 75h > 600[/tex]

Hope This Helps :)

Answer:

All you have to do is turn x-2y=6 into y=mx+b form. That would mean you need to get y by itself. Subtract x from 6. Then you have -2y=6-x. Now you have to divide both sides of the equation by -2. So then you have -2y/-2 = 6-x/-2. That turns out to y=3-1/2x Which is easier read by: y=1/2x - 3
