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.

Answer:
Both inequalities use the division property to isolate the variable, y. When you divide by a negative number, like –7, you must reverse the direction of the inequality sign. When you divide by a positive number, like 7, the inequality sign stays the same. The solution to the first inequality is y > -23, and the solution to the second inequality is y <>

Answer: x=6
Step-by-step explanation:
X = 6
Step-by-step:

What is the equation of the line that passes through (1, 2) and (8,9) in slope-intercept form?
Answers
Answer:
The equation of line that passes through (1, 2) and (8,9) in slope-intercept form is: [tex]y = x+1[/tex]
Step-by-step explanation:
The slope-intercept form of line is given by the formula:
[tex]y = mx+b[/tex]
Here m is the slope and b is the y intercept
Given
[tex](x_1,y_1) = (1,2)\\(x_2,y_2) = (8,9)[/tex]
First of all, the slope has to be found
[tex]m = \frac{y_2-y_1}{x_2-x_1}\\m = \frac{9-2}{8-1}\\m = 1[/tex]
Putting m=1 in the equation
[tex]y = x+b[/tex]
Putting the point (1,2) in the equation to find the value of b
[tex]2 = 1+b\\b = 2-1\\b = 1[/tex]
The equation is:
[tex]y = x+1[/tex]
Hence,
The equation of line that passes through (1, 2) and (8,9) in slope-intercept form is: [tex]y = x+1[/tex]

Answer:
8 grams
Step-by-step explanation:
The balance is in equilibrium, so the weights of the two sides are equal.
Let the weight of a square be s.
Left side: 2s + 4
Right side: s + 3(4) = s + 12
The weights are equal, so we set the two expressions equal.
2s + 4 = s + 12
s = 8
Answer: The weight of a square is 8 grams.
Question 2: The first step was the combine the like terms; in this example he is subtracting the 3x on both sides of the =.
Answer: x=14
only #2
Step-by-step explanation:
Step 1: Subtract 3x from both sides.
2x+6−3x=3x−8−3x
−x+6=−8
Step 2: Subtract 6 from both sides.
−x+6−6=−8−6
−x=−14
Step 3: Divide both sides by -1.
-x/-1=-14/-1

Answers
Answer:
exact form: x=17/10
Decimal form: x=1.7
mixed number form: 1 7/10
Answer:
x = 17/10 (as a fraction) or x = 1.7(as a decimal) or x = 1 7/10(as a mixed number)
Step-by-step explanation:
3(5-x) = 7x - 2
3 * 5 - 3* x = 7x - 2 (brackets means multiply)
15 - 3x = 7x - 2 (when over equal sign negative changed to positive)
15 + 2 = 7x + 3x
17/10 = 10x/10 (cross-cancel cuz u tryna isolate the x)
17/10 = x
