Step-by-step explanation:

x+3/x-2 - 1-x/x= 17/4

now let's put the expression on the upper side so it I'll be

x+3-x-2-1-x-x= 17×14

x-x-x-x+3-2-1= 238

+3-3= 238

= 238 answer

Answer:

The solution set is {-2/9, 4).

Step-by-step explanation:

(x + 3)/(x-2)  - (1-x)/x = 17/4

Multiply through by the LCD ( = 4x(x - 2):

(x + 3)4x - 4(1 - x)(x - 2) = 17x(x - 2)

4x^2 + 12x - 4(x - 2 - x^2 + 2x) - 17x^2 + 34x = 0

4x^2 + 12x - 4x + 8 + 4x^2 - 8x - 17x^2 + 34x = 0

-9x^2 + 34x + 8 = 0

We need 2 numbers  whose product = -72 ( -9 * 8) and whose sum is 34.

These are +36 and -2, so we write:

-9x^2 + 36x - 2x + 8 = 0

-9x(x - 4) - 2(x - 4) = 0

(-9x + 2)(x - 4) = 0

x = -2/9, 4.

Answer:

A = 58

B =:25

Step-by-step explanation:

C = A + B

83 = 9x + 4 + 4x + 1

83 = 13x + 5

13x = 78

x = 78/13

x = 6

A = 9x + 4 = 9 x 6 + 4 = 58

B = 4x + 1 = 4 x 6 + 1 = 25

F(x) = 3x - 5 and g(x) = x + 3, find (1-9)(x).
snow_lady [41]

f(x)= 3x - 5 is x = 5/3

g(x) = x +3 is x = -3

(1-9)(x) is -8x

Karissa begins to solve the equation (x – 14) + 11 = x – (x – 4). Her work is correct and is shown below. (x – 14) + 11 = x – (x
sdas [7]
Her work is incorrect because she accidentally changed -14 to -7 in the second step.
Working it out from the top we get
(x-14)+11=x-(x-4)
x-14+11=x-x+4
x-3=0+4
Final answer:
x=7
Hope I helped :)
