Answer:
<h2>
C</h2>
Step-by-step explanation:
G(x) is transformed from the parent function f(x)=x^2 by:
right 4 units
since we all know that the vertex form of a quadratic equation is y=a(x-h)^2+k
since 4 is h, and k is 0 ( graph is on the x-axis), we can write the equation of this graph:
g(x)=(x-4)^2, which is C
I think it might be c because theyre not equal
Hey, so x would be -10. If I need to type the work out I can just let me know.
Answer: y=-6/7x
Step-by-step explanation: A perpendicular slope is opposite reciprocal. The opposite reciprocal of 7/6 is -6/7. The equation of the perpendicular line is y=-6/7x.
Answer:
≈ 0.9 cm²
Step-by-step explanation:
I don't know if there is any easier way to solve this, I use 8th grade slope and line method to solve. suppose A is on origin, then the coordinates of triangle ABC are (0,0) (1,3) (4,1) and polygon DEFGH intersect line BC at F and G.
F is the intersect of y=2 and line BC, while G is intersect of x=3 and line BC.
Line BC: pass (1,3) and slope (m) = (1-3)/(4-1) = - 2/3,
F(x,2)
(2-3) / (x-1) = -2/3
2x-2 = 3 x = 2.5
*<u>F (2.5 , 2</u>)
G (3,y)
(y-3) / (3-1) = -2/3 y = 5/3
*<u>G (3 , 5/3)</u>
*<u>point I (3 , 2</u>)
segment FI = 3-2.5 = 0.5 = 1/2
segment GI = 2 - 5/3 = 1/3
area ΔFIG = (1/2 * 1/3) / 2 = 1/12 = 0.083
area of polygon DEFGH (region colored RED) = 1 - 0.083 = 0.917 ≈ 0.9 cm²
