Answer:
The segment should be 36 centimeters long
Step-by-step explanation:
Let us use the ratio method to solve the question
∵ The original scale is 1 cm : 8 m
∵ In the original drawing, the length of a segment is 9 centimeters
→ By using the ratio method
→ cm : m
→ 1 : 8
→ 9 : x
→ By using the cross multiplication
∵ 1 × x = 9 × 8
∴ x = 72 m
∴ The actual length of the segment is 72 m
∵ The new scale is 1 cm : 2 m
∵ The actual length of the segment is 72 m
→ By using the ratio method
→ cm : m
→ 1 : 2
→ y : 72
→ By using the cross multiplication
∵ y × 2 = 1 × 72
∴ 2y = 72
→ Divide both sides by 2 to find y
∴ y = 36
∴ The drawing length of the segment is 36 cm in the new scale
∴ The segment should be 36 centimeters long
A right triangle with leg lengths of 4 and 3 units has to be positioned in the coordinate plane to write a coordinate proof. Which set of coordinates would make the prrof easier to complete.
Answer:
We recommend to use a rectangular set of coordinates to make the proof easier to complete.
Step-by-step explanation:
A right triangle is a triangle whose leg are orthogonal to each other, then we need to use a set of coordinates whose axes are orthogonal to each other. Hence, we recommend to use a rectangular set of coordinates to make the proof easier to complete.

A store offers packing and mailing services to customers. The cost of shipping a box is a combination of a flat packing fee of $5 and an amount based on the weight in pounds of the box, $2.25 per pound. Which equation represents the shipping cost as a function of x, the weight in pounds?
f(x) = 2.25x + 5
f(x) = 5x + 2.25
f(x) = 2.25x − 5
f(x) = 5x − 2.25

X-4y=28 in slope intercept form
Answer:
y = 1/4x - 7
Step-by-step explanation:
Slope intercept form is y=mx+b
To turn the equation into slope intercept you would have to re-arrange it making sure to do the same thing on both sides.
x - 4y = 28
- x -x
-4y = -x + 28
Now divide both sides by -4
y = 1/4x -7
If you have any questions let me know. Hopefully this helps and have a great day!
The equation x - 4y = 28 can be written in slope-intercept form as y = (1/4)x - 7.
Given is an equation x - 4y = 28, we need to convert this in slope-intercept form,
To convert the equation x - 4y = 28 into slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept, we need to isolate the variable y.
Starting with the given equation:
x - 4y = 28
We can begin by moving the x term to the other side of the equation:
-4y = -x + 28
Next, we divide both sides of the equation by -4 to isolate y:
y = (-1/-4)x + (28/-4)
Simplifying further:
y = (1/4)x - 7
Now we have the equation in slope-intercept form, with a slope of 1/4 and a y-intercept of -7.

Let F = (2, 3). Find coordinates for three points that are equidistant from F and the y-axis. Write an equation that says P = (x, y) is equidistant from F and the y-axis
Answer:
The equation that says P is equidistant from F and the y-axis is [tex]P(x,y) =\left(1,\frac{3+y'}{2} \right)[/tex].
(1, 0), (1, 3/2) and (1,6) are three points that are equdistant from F and the y-axis.
Step-by-step explanation:
Let [tex]F(x,y) = (2,3)[/tex] and [tex]R(x,y) =(0, y')[/tex], where [tex]P(x,y)[/tex] is a point that is equidistant from F and the y-axis. The following vectorial expression must be satisfied to get the location of that point:
[tex]F(x,y)-P(x,y) = P(x,y)-R(x,y)[/tex]
[tex]2\cdot P(x,y) = F(x,y)+R(x,y)[/tex]
[tex]P(x,y) = \frac{1}{2}\cdot F(x,y)+\frac{1}{2} \cdot R(x,y)[/tex] (1)
If we know that [tex]F(x,y) = (2,3)[/tex] and [tex]R(x,y) = (0,y')[/tex], then the resulting vectorial equation is:
[tex]P(x,y) = \left(1,\frac{3}{2} \right)+\left(0, \frac{y'}{2}\right)[/tex]
[tex]P(x,y) =\left(1,\frac{3+y'}{2} \right)[/tex]
The equation that says P is equidistant from F and the y-axis is [tex]P(x,y) =\left(1,\frac{3+y'}{2} \right)[/tex].
If we know that [tex]y_{1}' = -3[/tex], [tex]y_{2}' = 0[/tex] and [tex]y_{3}' = 3[/tex], then the coordinates for three points that are equidistant from F and the y-axis:
[tex]P_{1}(x,y) = \left(1,\frac{3+y_{1}'}{2} \right)[/tex]
[tex]P_{1}(x,y) = (1,0)[/tex]
[tex]P_{2}(x,y) = \left(1,\frac{3+y_{2}'}{2} \right)[/tex]
[tex]P_{2}(x,y) = \left(1,\frac{3}{2} \right)[/tex]
[tex]P_{3}(x,y) = \left(1,\frac{3+y_{3}'}{2} \right)[/tex]
[tex]P_{3}(x,y) = \left(1,6 \right)[/tex]
(1, 0), (1, 3/2) and (1,6) are three points that are equdistant from F and the y-axis.
