Ths system of equations is

8x+6y=48 ..............>y = 48/6 -8x/6
2x−3y=−6 ..............>y = 6/3 + 2x/3

If we use a graphic tool, we can easily check the solution,
which is (x,y) = (3,4)

The ordered pair lies in Quadrant I

Write the equation of the line passing through points ( -2,-5) and (1,1)

Dennis_Churaev [7]

Answer:

The equation of the line is:

$y=2x-1$

Step-by-step explanation:

Given the points

(-2, -5)

(1, 1)

Finding the slope between the points

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(-2,\:-5\right),\:\left(x_2,\:y_2\right)=\left(1,\:1\right)$

$m=\frac{1-\left(-5\right)}{1-\left(-2\right)}$

$m=2$

We know the slope-intercept form of the line equation

$y=mx+b$

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

substituting the value m=2 and the point (-2, -5) to find the b-intercept

$y=mx+b$

-5 = 2(-2) + b

b = -5+4

b = -1

Now, substituting m=2 and b=-1 in the slope-intercept form to get the equation of a line

y=mx+b

y=2x+(-1)

y=2x-1

Thus, the equation of the line is:

$y=2x-1$

What is the solution of the system? Use the substitution method.

cricket20 [7]

Start by isolating one of the variables
x=-4y+2
Sub x into the other formula and solve for the y value of the solution.
3(-4y+2)+2y=11
-12y+6+2y=11
-12y+2y=11-6
-10y=5
y=-1/2
Sub the y value into the x formula you created.
x=-4(-1/2)+2
x=2+2
x=4
Therefore the solution is (4,-1/2) I think the answer is B unless the y value is actually -12.
Hope this helps :)

To the nearest tenth, what is the circumference of a circular pond with a radius of 14 meters? Use 3.14 for π.

Semmy [17]

Since the formula for circumference is
2 pi r, you can multiply 28 by pi to get 87.92
