Answer:
D
Step-by-step explanation:
x(-3x+4)=x*(-3)+x*4=-3x^2+4x
Answer:
C
Step-by-step explanation:
When doing linear equations or quadratics the constant which in this case is +2 means the entire line/parabola is shifted upwards
Answer:
D
Step-by-step explanation:
because you need to times the indice 2 by the 3
WRITE EQUATIONS....
f = k÷ g (inversely proportional....)
∴ if f= 40 and g= 5 K= (40×5) =200
now that u have k... and given g = 10...u can substitute to find f
f= 200÷10 =20
so f = 20
The bottom right graph is correct. x must fall between 3 and 6, so that automatically rules out the bottom left, as one of the points falls on 2.
the top left is incorrect because it doesn't show that x is greater than or EQUAL to three. it has an open circle rather than a closed circle. that's two answer choices eliminated.
from there, you just have to refer back to your given information:
<span>3≤x≤6
the given info says that x must be between or equal to 3 and 6. the top right graph leaves out a "step" because it has 5 and 6 as solid dots side by side.</span>
