The graph of a proportional relationship contains the point (8,4). What is the corresponding equation? Enter your answer as a fraction in simplest form by filling in the boxes.
y= — x
Given:
The graph of a proportional relationship contains the point (8,4).
To find:
The corresponding equation.
Solution:
If y in directly proportional to x, then
[tex]y\propto x[/tex]
[tex]y=kx[/tex] ...(i)
Where, k is the constant of proportionality.
The graph of a proportional relationship contains the point (8,4).
Putting x=8 and y=4 in (i), we get
[tex]4=k(8)[/tex]
[tex]\dfrac{4}{8}=k[/tex]
[tex]\dfrac{1}{2}=k[/tex]
Putting [tex]k=\dfrac{1}{2}[/tex] in (i), we get
[tex]y=\dfrac{1}{2}x[/tex]
Therefore, the required equation is [tex]y=\dfrac{1}{2}x[/tex].

Sunita creates a scale model of an aeroplane. The scale of the model is 4 cm to 15 m. Sunita's model has a wingspan of 17 cm. What is the wingspan of the real aeroplane?
Answer:
36.43m
Step-by-step explanation:
Let the wingspan of the real aeroplane = x
The scale of the model is 4 cm to 15 m.
= 4: 15 = 4/15.
Sunita's model has a wingspan of 17cm.
Hence:
4cm/15m = 17cm/xm
Cross Multiply
4x = 15 × 17
4x = 255
x = 255/4
x = 36.428571429 m
Approximately = 36.43 m
Therefore, the wingspan of the real aeroplane is 36.43m

HELP
Answer:
Y = 1
X= -1
Step-by-step explanation:
Y is 3 so x is 2 and if y = x then x - 1 would be one and then that would make y = 1
X is 2 - y which is 3 will equal -1
Answer:
Step-by-step explanation:
2x – 3y = -5.........(i)
у = х – 1................(ii)
Multiply equation (ii) by 3,
3у = 3х – 3.......(iii)
Add (i) and (iii)
2x – 3y = -5
+
-3x + 3y = – 3
=
-x = -8
x = 8
put the value of x in eq (ii)
у = х – 1
у = 8 – 1

The measure of angle Q is 70 degrees. Find the measure of angle P.
Answer:
∠ P = 40°
Step-by-step explanation:
Since PQ = PR then the triangle is isosceles and the base angles are congruent, then
∠ R = ∠ Q = 70° , so
∠ P = 180° - (70 + 70)° ← sum of angles in triangle is 180°
∠ P = 180° - 140° = 40°

A line through which two points would be parallel to a line with a slope of 3/4?
a
(0,-2) and (-4,-2)
b
(0,5) and (-4,2)
c
(0,2) and (-4,1)
d
(0,0) and (0,-2)
Answer:
F. (0, 5) and (-4, 2)
Step-by-step explanation:
We need to calculate the slope of each of the given sets of points until we find the set associated with a slope of 3/4:
F. (0,5) and (-4,2) As we go from (-4, 2) to (0,5), x increases by 4 and y increases by 3, so the slope is m = rise / run = 3/4. This is the line with slope 3/4.

Answer: 8m - 10n
Step-by-step explanation:
Answer:
28m-10n
Step-by-step explanation:
start by multiplying 4 by (8m-7n) and 6 by (3n-4m)
This will then give you 32m-28n and 18n-24m
Then, add the two answers together
32m-28n+18n-4m
This will give you your final answer of: 28m-10n

Find the slope and the y-intercept of the graph of the linear equation. 1. y=3x-7 2. y-1=-2/3x
Answer:
1) Slope: 3; y-intercept: -7
2) Slope: 2/3; y-intercept: 1
Step-by-step explanation:
y = mx + b; m is slope and b is y-intercept
1. y = 3x - 7
The equation is already in slope-intercept form, so you can find the slope and intercept.
Slope: 3
y-intercept: -7
2. y - 1 = 2/3x
For this one, you have to convert this into slope-intercept form (solving for y)
y - 1 = 2/3x
Add 1 to both sides
y - 1 + 1 = 2/3x + 1
y = 2/3x + 1
Now that the equation is in slope-intercept form, you can get the slope and y-intercept.
Slope: 2/3
y-intercept: 1
The basking shark can grow to a length of 30 feet. This is 176.47% of the maximum length of the beluga whale. Find the maximum length of the beluga whale. If necessary, round your answer to the nearest tenth.
a) 52.9ft
b) 17ft
c) 5.9ft
d)1.7ft
Answer:
b
Step-by-step explanation:
The maximum length of the beluga whale is 17 feet.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, The basking shark can grow to a length of 30 feet.
This is 176.47% of the maximum length of the beluga whale.
Assuming the maximum length of a beluga whale is x feet.
So, 176.47% of x is 30 feet.
∴ (176.47/100)×x = 30.
1.7647x = 30.
x = (30/1.7647).
x = 17 feet.

use the figure below and determine the angle measures. what is the measure of angle G?
Answer:
45
Step-by-step explanation:
First we want to understand the Base Angles Theorem
The Base Angles Theorem tells us that the base angles or the two bottom angles of an isosceles triangle are congruent.
Using this theorem, we can say that angle A and angle G are congruent meaning m∠A = m∠G. We can then write both of them as x.
We can create the equation ∠N + ∠A + ∠G = 180 degrees.
Knowing ∠N and knowing ∠A + ∠G = 2x, we can rewrite the equation into
90 + 2x = 180
We can then solve for x,
90 + 2x - 90 = 180 - 90
2x = 90
2x / 2 = 90 / 2
x = 45 degrees

The length, l , of a rectangle is 3 cm longer than twice the width, w. The perimeter of the rectangle is 66 cm.
Which system of linear equations could be used to find the length and width of the rectangle?
A. l = 3w + 2
2l + 2w = 66
B.l = 3w + 2
l + w = 66
C.I= 2w + 3
l + w = 66
D. l = 2w + 3
2l + 2w = 66
Answer:
The system of linear equations that could be used to find the length and width of the rectangle will be:
l = 2w + 3 cm
2w + 2l = 66
Hence, option D is correct.
Step-by-step explanation:
Let the width of the rectangle be = w cm
Given that the length, l, of a rectangle is 3 cm longer than twice the width, w.
Thus, the length of the rectangle be:
l = 2w + 3 cm
We know that the perimeter of the rectangle is:
P = 2w + 2l
Given that the perimeter of the rectangle = P = 66 cm
so substitute P = 66 in P = 2w + 2l
P = 2w + 2l
66 = 2w + 2l
Therefore, the system of linear equations that could be used to find the length and width of the rectangle will be:
l = 2w + 3 cm
2w + 2l = 66
Hence, option D is correct.
