Answer:q=-6
Step-by-step explanation:
If the solution of the system is {(x,y) : x-3y=4}, then both equation should have proportional coefficients:
[tex]1/2=-3/q=4/8[/tex]
Solve it:
1/2 = -3/q
q=-3*2
q=-6
Check whether q=-6 is correct answer, substituting this value into the first ratio:
[tex]1/2=-3/-6=4/8[/tex]
q=-6

Q = 2Step-by-step explanation:
If the solution to the system is the first equation only, then both equations should be same:
x - 3y = 4Qx - 6y = 8Double the first equation, then both of coefficients of y and constant will be equal:
2x - 6y = 8Qx - 6y = 8Comparing we get Q = 2

Choose...

Infinity many Solutions
No Solutions
One Solution
Answers
Answer:
no solutions
Step-by-step explanation:
plug in y to x:
15x + 5(8 - 3x) = 20
15x + 40 - 15x = 20 ( you would subtract 15x from 15x.)
0 + 40 = 20
40 = 20
40 does not equal 20 so it would be no solutions.
Using substitution, the system above has no solutions.
Given that,
The equations are 15x + 5y = 20 and y = 8 – 3x.Based on the above information, the calculation is as follows:
Here we put the y value
15x + 5(8 - 3x) = 20
15x + 40 - 15x = 20
0 + 40 = 20
40 = 20
Since 40 does not equal 20 so it would be no solutions.

Problem 1
Answer: 6.7----------------
Work Shown:
The two points are [tex](x_1,y_1) = (1,-2)[/tex] and [tex](x_2,y_2) = (4,4)[/tex]
Apply the distance formula to get the following
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(1-4)^2 + (-2-4)^2}\\\\d = \sqrt{(-3)^2 + (-6)^2}\\\\d = \sqrt{9 + 36}\\\\d = \sqrt{45}\\\\d \approx 6.7082039\\\\d \approx 6.7\\\\[/tex]
The distance between the two endpoints is roughly 6.7 units. This is the same as saying the segment is roughly 6.7 units long.
======================================================
Problem 2
Answer: 3.6----------------
Work Shown:
We'll use the distance formula here as well.
This time we have the two points [tex](x_1,y_1) = (3,1)[/tex] and [tex](x_2,y_2) = (5,-2)[/tex]
The distance between them is...
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(3-5)^2 + (1-(-2))^2}\\\\d = \sqrt{(3-5)^2 + (1+2)^2}\\\\d = \sqrt{(-2)^2 + (3)^2}\\\\d = \sqrt{4 + 9}\\\\d = \sqrt{13}\\\\d \approx 3.6055513\\\\d \approx 3.6\\\\[/tex]
This distance is approximate.

the equation would be (3∙18.50)+2x=104.50
Step-by-step explanation:
So you would do BEDMAS. First answer what in the brackets (3 ∙ 18.50=55.50)Then you subtract 55.50 on both sides
2x=104.50. then you just divide two by each side and the x will equal 24.50 So they parents tickets were 24.50.

Answer:
Option B : 1/2 is the correct answer.
Step-by-step explanation:
Given ordered pairs are;
(3, 6) and (5, 7).
We have to find the rate of change which is also known as slope.
Slope is the steepness of a line.
The formula of slope is given by;
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
m = [tex]\frac{7-6}{5-3}[/tex]
m = [tex]\frac{1}{2}[/tex]
Hence,
Option B : 1/2 is the correct answer.
