1) 234+(y+749)=3091
2)8405+347+x)=8995

[] Answer(s) []

[] Explanation []

Problem 1: 234 + (Y + 749) = 3091

Remove Parenthesis:

234 + Y + 749 = 3091

Group Like terms:

Y + 234 + 749 = 3091

Add The Numbers: 234 + 749 = 983

Y + 983 = 3091

Subtract 983 From Both Sides:

Y + 983 - 983 = 3091 - 983

Simplify:

Y = 2108

---------------------------------------------

Problem 2: 8405 + (347 + X) = 8995

Remove Parenthesis:

8405 + 347 + X = 8995

Add Numbers: 8405 + 347 = 8752

X + 8752 = 8995

Subtract 8752 From Both Sides:

X + 8752 - 8752 = 8995 - 8752

Simplify:

X = 243

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2
