Answer:
y > x+1 (D)
Step-by-step explanation:
this equation forms the same graph as shown in the question
Answer:
(3, 0) and (−1, −8)
Equation's:
<h3>
Substitute equation 2 into 1</h3>
2x − (x² − 9) = 6
2x - x² + 9 = 6
-x² + 2x + 9 - 6 = 0
-x² + 2x + 3 = 0
x² - 2x - 3 = 0
x² - 3x + x - 3 = 0
x(x - 3) + 1(x - 3) = 0
(x + 1)(x - 3) = 0
x = -1, x = 3
<h3>Find values for y</h3>
If x = -1, then y = (-1)² - 9 = -8
If x = 3, then y = (3)² - 9 = 0
<h3>Solution Set:</h3>
(x, y) = (-1, -8), (3, 0)
The first and third choices are irrational.
Answer:
Vertex: (-4, 1)
X intercepts: (-6, 0) and (-2, 0)
Y Intercepts: (0, -5)
Axis of Symmetry: X= -4
Step-by-step explanation:
Vertex of the parabola is the maximum or minimum point on the graph of the quadratic function
X intercepts are points of when a line or in this case a parabola intercepts the x axis, and where y = 0
Y intercepts are point of when a line or in this case a parabola intercepts the y axis, and where y = 0
Axis of symmetry is the point where if you divide the parabola in half, shows a symmetrical side
To solve for H, we use Sin
sin=opp/hyp
Now, we don't have the hypotenuse, so we have to multiply.
So: H= sin18×100
H= 30.9(correct to 1 significant figure)
To check for the correct answer, we take sin inverse on calculator (2nd F, sin), then 30.9
Then press the ab/c button then 100, then press =
You will get 17.99(correct to 1 s.f= 18)
That 18 you got was actually the sin18 or the 18 degrees!!!!!!!!!!
Hope this helps!!!!!
