Answer:
1. The answer for this question is corresponding angles.
2. The answer for this question is alternate interior
A quadratic equation is set up in the form of ax² + bx +c
First set equation = to 0
0= x² - 5x - 24
Next plug into quadratic formula( -b Plus or minus the √b²-4ac) ÷ 2a
[10 plus or minus √(25² - 4×1×24)] ÷ 2
Solve for inner parenthesis first
√625- 96 = √529
Now set up two equations
(10 + √529) ÷2 = x = 16.5
(10 - √529) ÷2 = x = -6.5
So therefore x = 16.5 and -6.5
Division CANNOT be commutative, here is why
lets say the problem is 24÷4
it is obviously 6
but when you flip 24÷4, you get 4÷24
and... 4÷24 is 0.16666666
6 and 0.1666 is totally different :p
Answer: 5/7
Step-by-step explanation:
Just take the square root of the top and the bottom. Square root of 25=5 and the square root of 49=7, so the square root of 25/49=5/7
1. (x + 2 < 5) Subtract two from each side to get (x < 3)
2. (x - 7 > -6) Add 7 to both sides to get (x > 1)
