Which what ? There are no choices to pick anything from.
If we can massage the equation to get ' y ' all alone on one side and everything else on the other side, then we can read the slope and y-intercept right from the equation. Let's do it.
You said
y - 3 = x + 6
Add 3 to each side:
y = x + 9
And there we have it.
The graph is a straight line. Its slope is 1, and it crosses the y-axis at the point where y=6.
Solve for x over the real numbers:
5 x^2 - 21 = 10 x
Subtract 10 x from both sides:
5 x^2 - 10 x - 21 = 0
Divide both sides by 5:
x^2 - 2 x - 21/5 = 0
Add 21/5 to both sides:
x^2 - 2 x = 21/5
Add 1 to both sides:
x^2 - 2 x + 1 = 26/5
Write the left hand side as a square:
(x - 1)^2 = 26/5
Take the square root of both sides:
x - 1 = sqrt(26/5) or x - 1 = -sqrt(26/5)
Add 1 to both sides:
x = 1 + sqrt(26/5) or x - 1 = -sqrt(26/5)
Add 1 to both sides:
Answer: x = 1 + sqrt(26/5) or x = 1 - sqrt(26/5)
Answer:
the one in the bottom is the graph in pretty sure
Well if its exponential it must be x ^n
