Hi!
Let's plug in some values:
x = 0, 1, 2
y = 7(0) - 5
y = -5
y = 7(1) - 5
y = 2
y = 7(2) - 5
y = 9
So three solutions include (0, -5), (1, 2), and (2, 9).
The answer is 18^8 because u add exponents
Answer:
b = ±16
Step-by-step explanation:
Normally to find the number we add to make it a perfect square
We take the coefficient of x
b
Divide by 2
b/2
Then square it
(b/2) ^2
In this case, we are adding 64
(b/2) ^2 = 64
Take the square root of each side
sqrt((b/2) ^2) = sqrt(64)
b/2 = ±8
Multiply each side by 2
b/2*2 = ±8 *2
b = ±16
Answer:
x < 0
Step-by-step explanation:
If you were to graph the function, you would get a parabola that opens down with the vertex at (0, 0). So, the graph is increasing from -∞ to 0.
