Answers
Answer:
A coordinate plane showing Falling Leaf, Time in seconds on the x-axis and Height in feet on the y-axis. A line is passing through (0, 12), (8, 10), and (16, 8).
Step-by-step explanation:
The y-intercept of the graph is the height of the leaf at the beginning, that is, 12 ft. This means that point (0, 12) is on the line.
The leaf falls to the ground at a rate of 0.25 feet per second, this means that after 8 seconds, the leaf travel 8*0.25 = 2 ft. Given that it started at 12 ft, its height is 12 - 2 = 10 ft. In other words, the point (8, 10) is on the line. Similarly, its height after 16 seconds is 12 - 16*0.25 = 8 ft, that is, the point (16, 8) is on the line.
Answer:
the answer is D
Step-by-step explanation:
A line is passing through (0, 12), (8, 10), and (16, 8).

The types of statement can be used to explain the steps of a proof is postulate and theorem.
What is Theorem?A statement that has been proven true or that can be proven is known as a theorem in mathematics. A logical argument is used to prove a theorem by using the deductive system's inference rules to show that the theorem follows logically from the axioms and other theorems that have already been proven.
Guessing and Conjecture is just striking some ideas without any definite conclusion.
A claim that is accepted as true without evidence, also referred to as an axiom. Lemmas and theorems are deduced from postulates, which serve as their fundamental building block.
Thus, the statement used in proof is Postulate or Theorem.

What is the equation, in slope-intercept form, of the line that is perpendicular to the line
y-4 = (x – 6) and passes through the point (-2, -2)?
Answers
Answer:
y=x
Step-by-step explanation:
slope intercept form:
y= mx +c, where m is the gradient and c is the y-intercept.
Let's rewrite the given equation in the form of y=mx+c, so that we can determine the gradient of the line.
y-4= x-6
y= x -6 +4
y= x -2
Thus, the gradient of the given line is 1.
the product of the gradients of perpendicular lines is -1.
(gradient of line)(1)= -1
gradient of line= 1
Thus, m=1.
y= 1x +c
y= x +c
To find c, substitute a coordinate.
When x= -2, y= -2,
-2= -2 +c
c= -2 +2
c=0.
Thus the equation of the line is y=x.

Answer:
D or x≥4
Step-by-step explanation:
The number has to be 4, since the dot lies on it, so that excludes A and B.
It is greater, because the arrow is pointing right instead of left.
Since the circle is closed, then it means that it includes 4.
So, C would not be the answer, because it is read as " x is greater than 4"
it should be D, which is " x is greater than or equal to 4" (since the circle is closed).

Answers
Answer:
b)
i) Focus ( 0,a) = [tex](0,\frac{1}{2} )[/tex]
ii) The equation of the directrix is
[tex]y = -\frac{1}{2} or y +\frac{1}{2} =0[/tex]
Step-by-step explanation:
Step(i):-
A parabola is the set of all points in a plane that are equidistant from a fixed line and a fixed point (not in a line) in the plane
• The Fixed line is called the directrix of the parabola.
• The Fixed point is called the focus of the parabola.
• A line through the focus and perpendicular to the directrix is called the axis of the parabola.
• The point of intersection of parabola with the axis is called the vertex of the parabola.
Given Parabola x² = 2 y
Comparing x² = 4 a y
4 a = 2
[tex]a = \frac{1}{2}[/tex]
Focus ( 0,a) = [tex](0,\frac{1}{2} )[/tex]
Step(ii)
The equation of the directrix is y = -a or y +a=0
The equation of the directrix is
[tex]y = -\frac{1}{2} or y +\frac{1}{2} =0[/tex]
The equation of the directrix is 2 y +1 =0

For the function above is the discriminate, positive, negative, or zero?
Answers
Answer:
0
Step-by-step explanation:
When there is one x-intercept, the discriminant is zero.
__
The discriminant is used to compute the difference between the roots. When it is positive, the real roots are different, so there are two x-intercepts.
When the discriminant is zero, there is no difference between the roots, so there is one x-intercept (as here).
When the discriminant is negative, there are no x-intercepts and the two roots are complex.

Solve system of equations for x + y: 3x + 2y = -18 & 2x + 9y =-12
Answers
Answer:
(- 6, 0 )
Step-by-step explanation:
Given the 2 equations
3x + 2y = - 18 → (1)
2x + 9y = - 12 → (2)
Multiplying (1) by 2 and (2) by - 3 and adding will eliminate the term in x, that is
6x + 4y = - 36 → (3)
- 6x - 27y = 36 → (4)
Add (3) and (4) term by term to eliminate x
- 23y = 0
y = 0
Substitute y = 0 into either of the 2 equations and evaluate for x
Substituting into (1)
3x + 0 = - 18
3x = - 18 ( divide both sides by 3 )
x = - 6
Solution is (- 6, 0 )
