Answer:
see explanation
Step-by-step explanation:
To determine which ordered pairs satisfy the equation substitute the x coordinate of the point into the right side and if the value obtained equals the y coordinate of the point then it satisfies the equation
(- 1, - 1)
x = - 1 : y = - 4 + 3 = - 1 ⇒ (- 1, - 1) satisfies the equation
(2, 11)
x = 2 : y = 8 + 3 = 11 ⇒ (2, 11) satisfies the equation
(4, 7)
x = 4 : y = 16 + 3 = 19 ≠ 7 ⇒ (4, 7) does not satisfy the equation
(7, 1)
x = 7 : y = 28 + 3 = 31 ≠ 1 ⇒ (7, 1) does not satisfy the equation
Answer:
x = 4.75 or 19/4 or 4 and 3/4
Step-by-step explanation:
10 - 4x = -9
-10 -10
-4x = -19
---- -----
-4 -4
x = 4.75 or 19/4 or 4 and 3/4
here is the solution.
Round the answer as needed.
Answer:
Step-by-step explanation:
3(x+4)-6=5x+5
distribute 3 through the parenthesis (3 times x + 3 times 4)=3x+12
3x+12-6=5x+5
subtract 12-6
3x+6=5x+5
Move the variable to the left and change the sign
3x-5x+6=5
collect like terms
3x-5x=5-6
-2x=5-6
divide both sides by -2
x=1/2
