Answer:
5/7
Step-by-step explanation:
3-(-2)/ 9-2
5/7 is the slope
Answer:
Step-by-step explanation:
xy = 300
x + y = 50 Solve for y
y = 50 - x substitute into xy = 300
x(50 - x) = 300 Remove the brackets.
50x - x^2 = 300 Bring the left to the right.
0 = x^2 - 50x + 300
This is a quadratic. It will have 2 solutions.
a=1
b = - 50
c = 300
Put these into the quadratic equation.
It turns out that x has two values -- both plus
x1 = 42.03
x2 = 6.97
x1 + y1 = 50
42.03 + y = 50
y = 50 - 42.03
y = 7,97
(42.03 , 7.97)
====================
x2 + y2 = 50
6.97 + y2 = 50
y2 = 50 - 6.97
y2 = 43.03
(6.97 , 43.03)
Answer: Can u pls help me withe my question?
Step-by-step explanation:
<span>x^2 + 0x - 1 = 0
x^2 - 1 = 0
This is a difference of two squares which factors into the product of a sum and a difference with the pattern: a^2 - b^2 = (a + b)(a - b).
(x + 1)(x - 1) = 0
x + 1= 0 or x - 1 = 0
x = -1 or x = 1
Answer: There are two real solutions.</span>
