Answer 1
Answer: (4,2). Explanation: In the elimination method you either add or subtract the equations to get an equation in one variable. When the coefficients of one variable are opposites you add the equations to eliminate a variable and when the coefficients of one variable are equal you subtract the equations to eliminate a variable. The Elimination Method
Step 1: Multiply each equation by a suitable number so that the two equations have the same leading coefficient. ...
Step 2: Subtract the second equation from the first.
Step 3: Solve this new equation for y.
Step 4: Substitute y = 2 into either Equation 1 or Equation 2 above and solve for x.
variable equation. It is relatively difficult to determine the values of x and y without manipulating the equations. If one adds the two equations together, the x s cancel out; the x is eliminated from the problem. Hence it is called the "elimination method”.

Determine whether each number is a solution of the
given inequality

8m - 6 < 10
when m = 3

O YES (m = 3 is a solution of the inequality)
o NO (m = 3 is not a solution of the inequality)

Answers

Answer:

NO (m = 3 is not a solution of the inequality)

The line graph is also attached below.

Step-by-step explanation:

Given

[tex]8m-6<10[/tex]

Add 6 to both sides

[tex]8m-6+6<10+6[/tex]

Simplify

[tex]8m<16[/tex]

Divide both sides by 8

[tex]\frac{8m}{8}<\frac{16}{8}[/tex]

Simplify

[tex]m<2[/tex]

Therefore, m = 3 NOT a solution of the inequality because 'm' must be less than 2.

Hence,

NO (m = 3 is not a solution of the inequality)

VERIFICATION:

Given

[tex]8m-6<10[/tex]

substitute m = 3

8(3) - 6 < 10

24 - 6 < 10

18 < 10

Find the slope of the line containing the points (0, 3) and (-6, 1)

Answers

Step-by-step explanation:

To find the slope of any linear line you would have to use the formula [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex].

(-6 , 1) = ([tex]x_{2}[/tex], [tex]y_{2}[/tex])

(0 , 3) = ([tex]x_{1}[/tex], [tex]y_{1}[/tex])

Now you would insert the values into the formula....

[tex]\frac{1-3}{(-6)-0}[/tex] = [tex]\frac{-2}{-6}[/tex] = [tex]\frac{1}{3}[/tex]

1/3 is your answer.

If you want to check your answer, you would use the formula mx + b= y

m= slope

x = the x-coordinate in either of the coordinates

b= the y-intercept

y = the y-coordinate of the coordinate you chose

mx +b = [tex]\frac{1}{3}[/tex](-6) +3 = -2 +3 = 1

1/3 is the correct answer

Hope this helps!!!

NEED HELP A triangle is cut from a rectangle. The height of the triangle is half of the unknown side length s. The area of the shaded region is 84 square inches. Write an equation you can use to find the side length s. An equation is =84.

Answers

Answer: 14s - 7s/2 = 84

Step-by-step explanation:

Given that s is the length of the unknown side:

Area of the shaded region = 84

Area of rectangle - Area of triangle = 84

Area of rectangle = L * W

= 14 * s

= 14s

Area of triangle = ¹/₂ * base * height

= ¹/₂ * 14 * s/2

= 7s/2

Area of shaded region:

14s - 7s/2 = 84

Solving for s:

14s - 7s/2 = 84

28s - 7s = 168

21s = 168

s = 168/21

s = 8 inches

Answers

Answer:

The equation a parallel line will be:

[tex]y=\frac{4}{3}x-9[/tex]

Hence, option B is correct.

Step-by-step explanation:

Given the equation

[tex]8x-6y=7[/tex]

Writing the line into the slope-intercept form

[tex]y = mx+b[/tex]

where m is the slope and b is the y-intercept

so

[tex]8x-6y=7[/tex]

[tex]6y\:=\:8x-7[/tex]

Dividing both sides by 6

[tex]y=\frac{4}{3}x-\frac{7}{6}[/tex]

comparing with the slope-intercept form

Thus, the slope of the line = m = 4/3

We know that the parallel lines have the same slope.

Thus, the slope of the parallel line is also 4/3

Using the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where m is the slope of the line and (x₁, y₁) is the point

substituting the values m = 4/3 and the point (6, -1)

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-\left(-1\right)=\frac{4}{3}\left(x-6\right)[/tex]

[tex]y+1=\frac{4}{3}\left(x-6\right)[/tex]

Subtract  1 from both sides

[tex]y+1-1=\frac{4}{3}\left(x-6\right)-1[/tex]

[tex]y=\frac{4}{3}x-9[/tex]

Thus, the equation a parallel line will be:

[tex]y=\frac{4}{3}x-9[/tex]

Hence, option B is correct.

Mom buys a rectangular rug with an area of 7 1/6 square meters. The length of the rug is 3 1/3 meters. What is the width of the rug?

Answers

Answer:

Step-by-step explanation:

Multiply the length by 2 so, 3 1/3 x 2 then subtract that answer from the area, and you have the width

The width of the rectangle given the area and length of the rectangular rug is 4 3/10 meters

Given:

Area of the rug = 7 1/6 square meters

Length of the rug = 3 1/3 meters

Area of a rectangle = Length × width

7 1/6 = 3 1/3 × w

43/6 = 10/3w

w = 43/6 ÷ 10/3

w = 43/6 × 3/10

w = (43 × 3) / (6 × 10)

w = 129/30

w = 4 9/30

= 4 3/10 meters

Therefore, the width of the rug is 4 3/10 meters
