can some one solve this its subtitution i need the brainlyist i will give yo a thanks a five star and brainlyist
Step-by-step explanation:
Hey there!
Given;
The equations are;
y = 8x...........(i)
y = 2x-12..........(ii)
Now;
Substituting the value of "y" from equation (i).
8x = 2x-12
8x-2x = -12
6x = -12
X = -12/6
Therefore, X= -2.
Now; Substituting the value of "y" in equation (i)
y = 8*-2
y = -16
Therefore, y= -16.
Therefore, x= -2 and y= -16.
Check:
y = 2x
-16= 8*-2
-16 = -16 (true).
Hope it helps...

Describe a sequence of transformations that take isosceles trapezoid T to its image T'
Answer:If you rotate trapezoid BEFG counter clockwise 90° then reflected across pointy you will have the image above
Step-by-step explanation:
Transformation involves changing the position of a shape
The transformation from T to T' is a 90 degree counterclockwise
From the figure, we can see that:
The angle between isosceles trapezoid T and its image T' is a right-angle (i.e. 90 degrees)Figure T' is at the right of TThis means that:
A 90 degree counterclockwise through point D will take trapezoid T to T'
Hence, the required transformation is a 90 degree counterclockwise through point D

Equivalent or Not?
Sarah thinks that the following
expressions are equivalent:
2x + 3 = x/2 + 4
Is she correct? If so, prove that these
two expressions are equivalent. If not,
explain what errors she made.
Answer:
equivalentStep-by-step explanation:
2x + 3 = x/2 + 4
2x - x/2 = 4 - 3
3x/2 = 1
x = 1 (2) / 3
x = 2/3
substitute the value of x=2/3 back into the equation:
2(2/3) + 3 = (2/3)/2 + 4
4/3 + 3 = 1/3 + 4
13/3 = 13/3 both are equal if x=2/3A civil engineer wants to know the opinions of drivers about online driving tests. She obtains a list of 730 drivers who have recently completed an online driving course and e-mails a questionnaire to a randomly selected group of 200 of these drivers. Only 102 of the questionnaires are returned. Identify the population and the sample in this study. (4 points)
The population is 200 and the sample is 102.
The population is 730 and the sample is 200.
The population is 102 and the sample is 730.
The population is 730 and the sample is 102.
The population is 200 and the sample is 730.
Answer: The population is 730 and the sample is 102.
Step-by-step explanation:
When we have a given set of elements, N elements, the population is N.
And if we do statistics with A of these N elements, the sample is A.
In this case, the population is the set of the 730 drivers, then the population is 730.
And while 200 of them are randomly selected, we can only work with 102 of them (because we have only 102 returned questionnaires).
Then the sample will be 102.
Then the correct option is:
The population is 730 and the sample is 102.
Answer:
730 and 102.

What is inequality?Inequality is simply a type of equation that does not have an equal sign in it. Inequality is defined as a statement about the relative size as we will as is used to compare two statements.
A school is planning a fundraiser with all profits going to charity.
Ticket Sales: 200x − 10x²
Event Cost: 500 + 20x
The amount of profit is found by subtracting the total cost from total ticket sales. A profit of $200 or more.
Event cost − Total sales ≥ Profit
(500 + 20x) − (200x − 10x²) ≥ 200
− 200x + 10x² + 500 + 20x − 200 ≥ 0
10x² + 180x − 700 ≥ 0
10x² − 180x + 700 ≥ 0
x² − 18x + 70 ≥ 0
On simplifying, we have
(x − 5.69) (x − 12.33) ≥ 0
x ≥ 5.69, 12.33
Thus, the value of the x should be more than or equal to 5.69. Then the correct option is A.

Jim drove 756 miles in 12 hours.
At the same rate, how many miles would he drive in 7 hours?
Answer:
441
Step-by-step explanation:
Use a proportion.
756 miles is to 12 hours as x miles is to 7 hours
756/12 = x/7
12x = 7 * 756
12x = 5292
x = 441
Answer: 441 miles
Answer:
441
Step-by-step explanation:
756 divided by 12 = 63
Jim drives 63 miles in 1 hour
Multiply 63 by 7
63 ⋅ 7 = 441
Jim will drive 441 miles in 7 hours

Which ordered pair would form a proportional relationship with the point graphed below? On a coordinate plane, a line with negative slope goes through points (negative 20, 10), (0, 0), and (20, negative 10). (10, –20) (–30, 20) (–10, 5) (35, –20)
Answer:
Answer:
(5, 20)
Step-by-step explanation:
We can find the slope of the line
m = (y2-y1)/(x2-x1)
= (40-0)/(10-0)
= 40/10
=4
Since the line goes through (0,0) the y intercept is 0
y = mx+b
y = 4x
Lets check the points by substituting into the equation
40, 10) 10 = 4*40 10 =160 no
(–5, –10) -10 = 4*-5 10 = -20 no
(5, 20) 20 = 4*5 20 = 20 yes
(–10, –20) -20 = 4*-10 -20 = -40 no
