Answer:
okay
vertex:(2,4)
domain: (-∞,∞)
range: [4,∞)
Step-by-step explanation:
to find the vertex from the equation
f(x) = (x − 2)² + 4
an easy way is to use the numbers given. so the vertex of this equation is x= 2 (because it is always the opposite of itself in the equation) and y= 4 because the point is going up 4.
to find domain is easy. domain is on the x-axis so the equation is a parabola so it has to points at the same direction. therefore it has a domain that goes from negative infinity to positive infinity.
lastly to find range, which is on the y-axis is to find from where the parabola starts and is pointing, either up or down. in this equation the vertex, which is also the starting point starts at 4 and continues to go on- to infinity.
ps i hope this helps.

Option A will be the correct answer
Answer:
x + y = - 3.6
2x - z = 1
x + y + z = - 3.8
y - x = - 4.4
Step-by-step explanation:
We have to evaluate the given expressions of x, y, and z where, , y = - 4 and z = - 0.2.
So, x + y = 0.4 + (- 4) = - 3.6
And, 2x - z = 2(0.4) - (- 0.2) = 1
And, x + y + z = 0.4 - 4 - 0.2 = - 3.8
Finally, y - x = - 4 - 0.4 = - 4.4 (Answer)
4 3/16=(4·16+3)/16=67/16=4,1875 (pink ribbon)
5 1/16=(5·16+1)/16=81/16=5,0625 (green ribbon)
4,1875+5,0625=9,25 (total)
9,25·1,60=$14,8
<em>Answer: $14,8</em>
