We have to write it mathematically and choose the correct options out of given options.
Consider the given expression "four times the square of a number is thirty-six"
Then
let the number be x ,
Then four times the square of a number written mathematically as
And given "four times the square of a number is thirty-six" written mathematically as
Therefore, "four times the square of a number is thirty-six" written mathematically as
Option (b) is correct.
Answer:
(x, y) ==> (-4, -3)
Step-by-step explanation:
-2(3x + y = -15) ==> -6x - 2y = 30
3x + 2y = -18
-6x - 2y = 30
3x + 2y = -18
-3x = 12
/-3 /-3
x = -4
Now, we solve for y:
-6x - 2y = 30
-6(-4) - 2y = 30
24 - 2y = 30
-24 -24
-2y = 6
/-2 /-3
y = -3
(x, y) ==> (-4, -3)
Hope this helps!
