Answer:
-9
Step-by-step explanation:
b² - c²
= 4² - (-5)²
= 16 - 25
= -9
Answer:
(3y + 5) / (y^2)
Step-by-step explanation:
Sorry it's not actually in fraction format. That little button thing is having troubles atm on my end. Hope this is okay
y = 8 -2x
x + 2 (8 - 2x) = 1
x + 16 - 4x = 1
x - 4x = -15
-3x = -15
x = 5
If x = 5, then we can substitute in...
5 + 2y = 1
2y = -4
y = -2
Now let us check that by substituting those values in to the equation
2x + y = 8
2 (5) + (-2) = 8
That is correct so we have the right values for x and y/
Value of y = 30 and value of x = 30.3
