Answer:
3(-1)-5-6(-1)-2. You found the value of X, so you need to put it back into the equation to see if it equals out.
Answer:
y = .75x - 4.5
Step-by-step explanation:
y = mx + b
m = slope ; b = y-int
slope = rise/ run = 3/4 = .75
y = .75x + b
Because it is hard to determine the exact y-intercept, we plug in a point (2,-3):
-3 = .75(2) + b
-3 = 1.5 + b
-4.5 = b -->
y = .75x - 4.5
Answer:
The function has two x-intercepts.
The vertex of the function is (one-quarter, negative 6 and one-eighth).
Step-by-step explanation:
Given that the vertex is located at (0.25, -6) and the parabola opens up, the function has two x-intercepts.
f(x) = 2x² - x - 6 has the following coefficients:
a = 2
b = -1
c = -6
x-coordinate of the vertex is:
x = -b/(2a)
x = 1/(2*2) = 1/4
y-coordinate of the vertex is:
f(1/4) = 2(1/4)² - 1/4 - 6 = -6 1/8
Answer:
y=3x+10
Step-by-step explanation:
2=-12+b
b=10
Answer: false.
Step-by-step explanation:
it's only a terminating decimal if you end up with a remainder of 0.
