Answer: S
Step-by-step explanation:
w + ? - s = w
w + s - s = w
w = w
Answer:
(-1, -1) and (2, 2)
Step-by-step explanation:
Substitute for y in the first equation and solve the quadratic.
x = x^2 -2
x^2 -x -2 = 0 . . . . subtract x
(x -2)(x +1) = 0 . . . .factor
Solutions are the values of x that make these factors be zero:
x = 2, x = -1
Since y=x, the solutions are ...
(x, y) = (-1, -1) and (2, 2)
A: 1.9 Kilograms of oranges for rs 665.
B: 12 liters of petrol will make a car travel 120 km.
I’ll be assuming you meant k as in
the a in a quadratic equation:
ax^2 + bx + c
kx^2 + bx + c.
In this case, the “k” will indicate whether the graph will be opening upwards to form a “u” shape or it opens downwards to form a “n” shape
When “k” is positive, the graph would open upwards and form a “u”.
If “k” is negative, the graph would open downwards and form a “n”.
Have a great day ahead!
