Answer:
The pine is 12 m tall and the fir is 12 m tall
Step-by-step explanation:
System of Equations
Let's call:
x = height of a pine tree
y = height of a fir tree
The combined height of one fir tree and one pine tree is 21 meters. This leads to the equation:
x + y = 21 [1]
The height of 4 fir trees is 24 meters taller than one pine tree:
4y = x + 24 [2]
From [1]:
x = 21 - y [3]
Substituting in [2]:
4y = 21 - y + 24
Adding y:
5y = 45
Dividing by 5:
y = 9
Substituting in [3]:
x = 21 - 9 = 12
The pine is 12 m tall and the fir is 12 m tall

A triangle is dilated with a center of dilation at the origin. Point P is on the figure and P' is the corresponding point on the image of the dilation. Point P is at (-2, 3) and P' is at (-8, 12). Which rule best represents the dilation? *
Answer:
(x, y) → (4x, 4y)Step-by-step explanation:
Dilation is applied by the rule:
(x, y) → (kx, ky), where k is the scale factorWe have
(x, y) = (-2, 3) and (kx, ky) = (-8, 12)Substitute and solve for k
-8 = -2k and 12 = 3k ⇒ k = 4So the rule is

Step-by-step explanation:
the sum of the angles in a triangle add up to equal 180
180-73-13=94
Answer: X = 89°
Step-by-step explanation:
At first glance I could tell this was an isosceles triangle, the angles of an isosceles triangle add up to 180°. So just add 73° + 13° = 91° so then you subtract 91° from 180° and you get 89°.

How to calculate 46% of 50
Answer:
the answer is 23
Step-by-step explanation:
100/50=2
46/2=23
Answer:
23
Step-by-step explanation:
50/x=100/46
(50/x)*x=(100/46)*x - we multiply both sides of the equation by x
50=2.17391304348*x - we divide both sides of the equation by (2.17391304348) to get x
50/2.17391304348=x
23=x
x=23
now we have:
46% of 50=23
Jillian buys 3.6 meters of fabric. The fabric costs $5.75 for each meter.
How much does Jillian spend for the fabric?
A. $9.35
B. $17.25
C. $18.57
D. $20.70
Total amount spend by Jillian for the fabric is $20.7.
What is division?Division is a process of splitting a number into two or more equal parts.
Given is that Jillian buys 3.6 meters of fabric. The fabric costs $5.75 for each meter.
Assume that Jillian spend ${x} for the fabric.
Total length of fabric bought by Jillian = 3.6 meters
Cost of 1 m of fabric = $5.75
So, we can write the total cost of fabric as -
x = 3.6 x 5.75
x = 20.7
Therefore, total amount spend by Jillian for the fabric is $20.7.

Rob is making for his young son a replica armchair of one he uses. The ratio of the length of the arm of the old chair to that of the new chair is 3:2. The arm of the old chair is 9 inches long. How many inches long will the arm of the new chair be?
Answer:
As the ratio of the length of the arm of the old chair to the length of the arm of the new chair is 3/2, and the length of the old chair is 9 inches, hence the length of the arm of the new chair is 6 inches.

What is the vertex for the quadratic
y = 2(x-3)^2 - 4? Type as (h.k)
Answer:
(3,-4)
Step-by-step explanation:
You can find the vertex where x = -b/2a
To find the values of a and b, it would be easier to write the equation in standard form, which is y = ax^2 + bx + c
y = 2(x^2 - 6x + 9) - 4
y = 2x^2 - 12x + 18 - 4
y = 2x^2 - 12x + 14
In this equation, a = 2 and b = -12.
So let's plug that into x=-b/2a
x = -(-12)/2(2)
x = 12/4
x = 3
Now we have the x, we can just plug that into the original equation and get the y coordinate for the vertex.
y = 2(x - 3)^2 - 4
y = 2(3 - 3)^2 - 4
y = -4

Which ordered pair describes a point that is located 5 units to
the right of the origin and 2 units below the x-axis?
Answer:
(5,-2)
Step-by-step explanation: the right of the origin is a positive number and below is negative there fore if you go right 5 it would be 5 and down 2 would be -2 .
The ordered pair describes a point that is located 5 units to the right of the origin and 2 units below the x-axis are (5, -2).
What is the coordinate grid?A coordinate grid has two perpendicular lines, or axes labeled just like number lines. The horizontal axis is usually called the x-axis. The vertical axis is usually called the y-axis. The point where the x- and y-axis intersect is called the origin.
Given a statement for coordinates a point that is located 5 units to
the right of the origin and 2 units below the x-axis,
so the left side of the x-axis is the negative value of x and the right side of x-axis is the positive values of x.
5 units to the right, which is the coordinate of x is 5
and the upper of x-axis is the positive side of the y-axis and down of x-axis is the negative side of the y-axis,
2 units below the x-axis, which is coordinate of y is -2
point is (5, -2).
Hence the coordinates of points are (5, -2).

A parabola has a vertex at (0,0). The focus of the parabola is located at (4,0). What is the equation of the directrix? x=−4 y=−4 x=4 y=4
The equation of directrix of the parabola will be x = -4.
What is directrix ?Directrix is a straight line distance to which from any point of a conic section is in fixed ratio to the distance from the same point to a focus. The directrix is perpendicular to the axis of symmetry and does not touch the parabola.
We have,
Vertex of parabola = (0, 0),
Focus of the parabola = (4, 0),
Now,
The Equation of directrix is given by y = -a
Where,
The equation of the parabola, [tex]y^2 = 4ax[/tex],
And,
Focus at (a, 0),
i.e. a = 4 (As the given focus is (4, 0))
And,
The axis of the parabola is the positive x − axis.
So,
The equation of the directrix of this parabola,
x + a = 0,
i.e.
x + 4 = 0
⇒
x = -4
Hence, we can say that the equation of directrix of the parabola will be x = -4.
