Answer:
-2
Step-by-step explanation:
- and - is positive so -4+2 is -2
Answer:
Step-by-step explanation:
Here, we assume that point A is (-1, 0) and point B is (z, 2). Since angle BAD is 60°, we have ...
2/(z+1) = tan(60°) = √3
z = (2/√3) -1
Putting the value of z into the equation for the parabola lets us find "a".
2 = a(z +1)(z -5) = a(2/√3)(2/√3 -6)
Then ...
a = 2/(4/3 -12/√3) = (6√3)/(4√3 -36)
a = -(3+9√3)/52 ≈ −0.357470332079
Slope intercept form is y = mx + b
m=slope and b=y-intercept
In this equation m is 2 and b is -3
That means that you will plot a point at -3 on the y axis and go up 2 and right 1.
You will continue to do that and you will get some points
Some points you will get are (-2,-7) (-1,-5) (1,-1) (2,1) (3,3) (4,5) (6,9)
Hope this helped!
7. C. y = 2x - 3
8. Both are correct
Step-by-step explanation:
7. Multiply the x value by 2, then subtract three. You eill notice they all equal to the corresponding y value
8. Divide each value by 2, (the same as multiplying by one half ) then subtract 2 from the quotient. you will get the corresponding y value for both tables.
