Answer:
A, D, F
Step-by-step explanation:
A. True, because 
represents quadratic function (the greatest power of x is 2)
B. False, because this function is quadratic, so cannot be linear
C. False. The vertex of the parabola is at point (-7,4) (see diagram)
D. True. The axes of symmetry is the line x=-7 that passes through the vertex.
E. False. The y-intercept is at point x=0 and 
F. True. The graph has the maximum at vertex, where 
G. False. The graph of the parabola intersects the x-axis at two points (-9,0) and (-5,0), so x=-9 and x=-5 are two real solutions of the equation f(x)=0.
Assuming that 3:5 is Teagan to Sadie: Teagan has 90 pieces of candy and Sadie has 150 pieces of candy.
1) 3 (Teagan’s share) + 5 (Sadie’s share) = 8 (total shares).
2) 240 (total candy)/8 (total shares) = 30 (each share)
3) 3 (Teagan’s share) • 30 (amount of candy in each share) = 90 (Teagan’s amount is candy)
4) 5 (Sadie’s share) • 30 (amount of candy in each share) = 150 (Sadie’s amount of candy).
Check:
90 + 150 = 240
Y=6x-11
the slope of the original line is 6. the slope of a line perpendicular would be a negative inverse, so the slope of the perpendicular line is -1/6
Answer:
No.
Step-by-step explanation:
No, because 23 > 10 + 10.
If any side is equal or greater than the sum of the other 2 sides no triangle can be drawn.
