Answer:
1 3/4
Step-by-step explanation:
you have to convert the mixed numbers into improper fractions first
2 1/2 turns into 5/2
then you make the denominators the same
5/2 turn into 10/4
then you subtract
10/4 - 3/4 = 7/4
then you turn it into a mixed number
7/4 turns into 1 3/4
Answer: (3,1)
Step-by-step explanation: Use the midpoint formula
Answer:
y = -2 -5
Step-by-step explanation:
x - 2y = 14
-2y = -x + 14
y = 1/2x - 7
-3 = -2 (-1) + b
-3 = 2 + b
-5 = b
y = -2 -5
Answer:
X+Y =23
X-Y =7

Answer:
- x = 0 or 1
- x = ±i/4
- x = -5 (twice)
Step-by-step explanation:
Factoring is aided by having the equations in standard form. The first step in each case is to put the equations in that form. The zero product property tells you that a product is zero when a factor is zero. The solutions are the values of x that make the factors zero.
1. x^2 -x = 0
x(x -1) = 0 . . . . . x = 0 or 1
__
2. 16x^2 +1 = 0
This is the "difference of squares" ...
(4x)^2 - (i)^2 = 0
(4x -i)(4x +i) = 0 . . . . . x = -i/4 or i/4 (zeros are complex)
__
3. x^2 +10x +25 = 0
(x +5)(x +5) = 0 . . . . . x = -5 with multiplicity 2
