Answer:

y =  -5/6

Step-by-step explanation:

7y - 3y + 2 = -8y - 8

12y + 2 = -8

12y = -10

y = -10/12 = -5/6

-7y -3y +2 = -8y-8

-10y +2 = -8y-8

-10y +8y = -8 -2

-2y = -10

2y = 10

y = 10/2 = 5

A triangle has a base of 7 1/8 feet and height 7 1/5 ft. what is the area as a mixed number
sleet_krkn [62]

The answer is 25 13/20 square feet.

In order to complete this operation, it is first best to change your mixed numbers into improper fractions.

7 1/8 = 57/8

7 1/5 = 36/5

Now that we have these, we can put them into the triangle formula.

A = 1/2bh

A = (1/2)(57/8)(36/5)

A = 1026/40

You can then simplify this fraction by dividing the top and bottom by a factor of 2.

A = 513/20

Then, because we know 20 goes into 500, 25 times, we can pull that out and be left with a remainder of 13/20.

A = 25 13/20

Give the values of a, b, and c needed to write the equation's general form. 2/3(x - 4)(x + 5) = 1
ale4655 [162]

The first step is to write this equation into general form. The general form of an equation is:

ax^2 + bx + c = 0

To make this equation to general form, you have to simplify the equation first.

2/3(x-4) (x+5) = 1

2/3 (x^2 + 5x – 4x – 20) = 1

2/3(x^2 + x -20) = 1

2/3x^2 + 2/3x – 40/3 = 1

2/3x^2 + 2/3x – 40/3 – 1 = 0

2/3x^2 +2/3x – 43/3 = 0

Therefore, a = 2/3 ; b = 2/3 ; c = -43/3

Let f(x)=x-2 and g(x)=x2-7x-9 fins f(g(-1))
vlabodo [156]
The answer is -3 because you’re plugging g(x) into f(x). For every x there is in f(x), plug in g(x)’s equation. After you get another equation (simplified), which is x^2 -7x -11, plug -1 for every x and condense.

(40x9)÷(4x8)=x solve for variable of x
nikklg [1K]
The answer is:  " x = 11 ¼ "  ; or write as:  " x = 11.25 " .
_________________________________________________
Explanation:
_________________________________________________
  (40*9) ÷ (4*8) = x  ;  Solve for "x" ;

(40 * 9 = 360) .

(4 * 8 = 32) .

(360) ÷ (32) = 45/4 = 11 ¼  ; or write as:  11.25 .
