In this problem it just goes left to right, 1-18+25 = -17+25 = 8
(1-18)+25-17+25=8<span>
</span>When you do addition and subtraction they are reversible so you just go left to right
Answer:
<h2>f(x) = -x² + 2x + 4</h2>
Step-by-step explanation:
We have quadratic functions f(x) = ax² + bx + c.
c - y-intercept
If a > 0, then a parabola opens up and has a minimum in a vertex.
If a < 0, then a parabola opens down and has a maximum in a vertex.
The function has maximum and y-intercept of 4:
a < 0 and c = 4
Answer: the answer would be Y
Step-by-step explanation: I took the test
Answer:
<em>Distance ⇒ 5 meters</em>
Step-by-step explanation:
If we are to name the point with which Patrick stands P, Eddie's point E remains 4 meters south such that Dustin ( D ) is 3 meters to the right;
This in fact forms a 90 degree triangles, a right triangle with legs provided to be 4 and 3 knowing Eddie's remains 4 meters south, Dustin 3 meters to the right. If we are to determine how far apart Patrick and Dustin are, this is the hypotenuse of the right angle triangle formed, and the length can be determine through Pythagorean Theorem;
4^2 + 3^2 = x^2, x ⇒ distance between Patrick and Dustin,
16 + 9 = x^2,
x^2 = 25,
<em>Distance ( x ) ⇒ 5 meters</em>
y-intercept: (0, 1)
Line of symmetry calculation: x = -b/2a = -(-2)/2(2) = 0.5
Line of symmetry: x = 0.5
Open UP or DOWN: Opens UP
Min or Max: Min
Vertex: (0.5, 0.5)
Domain: {x|x ∈ ℝ}
Range: {y|y ≥ 1/2}
