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: -4 (m + 6) = -8
We can use the distributive property for the first half of the equation.
-4 × m = -4m
-4 × 6 = -24
-4m - 24 = -8
Now we add 24 on bothe side sof the equation to get -4m by itself.
-4m - 24 + 24 = -8 + 24
Now we get -4m = 16
Divide -4 on both sides to get m by itself
-4m/-4 = 16/-4
Simplify and we get m = -4
Step-by-step explanation:
the value of root three is given already so the question is asking you to round it of to the nearest 1000 which means there should be three numbers after the decimal point.

Answer:
15.2 mph
Step-by-step explanation:
2.4÷(x+4)=1.4÷(x-4)
1.4(x+4)=2.4(x-4)
1.4x+5.6=2.4x-9.6
-x=-15.2
x=15.2
Hope this helps!
