Answer:
Option D: Multiply the second equation by 4 and then add the result to the first equation is the correct answer.
Step-by-step explanation:
Given that:
x-4y = 2
2x+y = 12
For elimination, one of the variable is eliminated.
In this system,
we can either multiplying the first equation by 2 or second equation by 4.
Then we can add the equations.
By multiplying the second equation with 4 and then adding both equations, we can eliminate the variable y.
4(2x+y=12)
8x+4y=48
By adding
(x-4y)+(8x+4y)=2+48
7x=48
Hence,
Option D: Multiply the second equation by 4 and then add the result to the first equation is the correct answer.

Step-by-step explanation:
P (0,0) Q (2,0) R (1,3)
PR² = (3-0)² + (1-0)² = 10
RQ² = (3-0)² + (1-2)² = 10
PR = RQ

Wayne has a recipe that says to heat the oven to 160°C. Wayne evaluates the expression 1.8C + 32 when C= 160 to convert the temperature to degrees Fahrenheit To which temperature should Wayne heat the oven?
Answers
Wayne should heat the oven to a temperature of 320°F for a recipe.
What is the algebraic expression?Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers. Unknown variables, numbers, and arithmetic operators make up an algebraic expression.
Wayne has a recipe that says to heat the oven to 160°C.
To convert a temperature in degrees Celsius to degrees Fahrenheit, we can use the formula:
F = 1.8C + 32
Given that C= 160, we can substitute it into the formula:
F = 1.8(160) + 32
F = 288 + 32
F = 320
Therefore, he should heat the oven to 320°F.

ChallengeThe price of Stock A at 9 AM Was $15.11. Since then, the price has been increasing at the
rate of $0.12 each hour. At noon the price of Stock B was $15.86. It begins to decrease at the rate of
$0.11 each hour. If the two rates continue, in how many hours will the prices of the two stocks be the
same?
In about hours, the prices of the two stocks will be the same.
(Round to the nearest tenth as needed
Answers
Answer:
Step-by-step explanation:
The information gives the Slope and y intercept of the line for stock A. At 9am, time = 0, the stock price is $15.11, the y intercept or b. The Slope of the line is 12 cents per hour, it is a positive Slope so it will rise from left to right.
The line in Slope form is
y= 0.12x+15.11
Stock B at noon, so 3 hours later, is $15.86 and is decreasing at a rate of 11 cents per hour.
We know the Slope is -0.11 and we know a point on its line is (3,15.86). From this we can solve for the y intercept by substituting the x and y values from the coordinate into the Slope equation.
15.86 = -0.11(3) + b
15.86 = -0.33 + b
Add 0.33 to both sides
16.19 = b so the equation of the line of stock B is y= - 0.11x + 16.19
Since we have two equations solved for y, we can set them equal to each other and solve for x
0.12x + 15.11 = - 0.11x + 16.19 add 0.11x - 15.11 to both sides
0.23x = 1.08 divide both sides by 0.23 to solve
x = 4.69565 to the nearest tenth 4.7 hours after 9am the two stocks will be the same price.

Step-by-step explanation:
Answer:
I don't know but I am pretty sure it can't be C or D.
Step-by-step explanation:
The slope of line CD simplifies to 2, so for the perpendicular line to be perpendicular, it must be an opposite reciprocal, meaning -1/2 or -0.5. I don't know what B equals though, whether it is positive or negative.

What is (x)
Answers
Answer:Can u sum it up?
Step-by-step explanation:
Answer:
47
Step-by-step explanation:
Step-by-step explanation:
(Base1 + Base2)/2 = midsegment
1. ((2x+15) + (6x-37))/2 = 3x+5
2. (8X-22)/2 = 3x+5
3. ((8x-22)/2))2 = (3x+5)2
4. 8x-22=6x+10
5. 2x-22=10
6. 2x-22+22=10+22
7. 2x=32
8. x=16
Now that you have solved for X add the value to line RS
RS = 2(16) + 15
RS = 32 + 15
RS = 47
