-3 (x + 5) = -9
x=?
Answer:
x=-2
Step-by-step explanation:
-3 (x + 5) = -9
Divide each side by -3
-3 (x + 5)/-3 = -9/-3
x+5 = 3
Subtract 5 from each side to isolate x
x+5-5 = 3-5
x=-2
Answer:
The coordinates of point B are (-3,2)
Step-by-step explanation:
we know that
The formula to calculate the midpoint between two points is equal to
we have
substitute
Find the value of x_2
we have that
Find the value of y_2
we have that
therefore
The coordinates of point B are (-3,2)
Answer: the other rational number is 118/19
Answer:
-118/19
Step-by-step explanation:
let x, y = the two rational numbers, respectively.
What do we know?
Step one: Plug in the values:
-15/19 + y =-7
Step two: Isolate the variable by adding 15/19 on both sides
y = -7 +15/19
Step three: Simplify the right side
Use basic addition to add the two numbers:
y = - 118/19
