Si a, b y r son números reales (y si a y b no son iguales a 0), ax+by = r se denomina ecuación lineal en dos variables. (Las “dos variables” son la x y la y.) Los números a y b se denominan los coeficientes de la ecuación ax+by = r. El número r se denomina constante del eje de ecuación + por = r.

Given a line with equation 3x +7y = 21. write an equation in point-slope form of the line parallel to the given line through the
guapka [62]

Answer:

The equation of the line is y = -3/7x - 23/7

Step-by-step explanation:

To start we need to find the slope of the original line. We can do this by solving the equation for y.

3x + 7y = 21

7y = -3x + 21

y = -3/7x + 3

Now we know the slope to be -3/7. Since parallel lines have same slopes, we know the new line also will have a -3/7 slope. We can now use that along with the given point in point-slope form to find the equation.

y - y1 = m(x - x1)

y + 5 = -3/7(x - 4)

y + 5 = -3/7x + 12/7

y = -3/7x - 23/7

What is the y-coordinate of the solution of the system of equations?
Vladimir [108]
The solution will be (7,-5), so the y-value is -5${y=3x-26 \atop y=2x-19}$

We can subtract y=2x-19 from the top, resulting in 0=x-7, or x=7.

If we then put x=7 into the top formula, we get:

y=3(7)-26

y=21-26

y=-5

The length of rectangle is represented by 8x - 3. The width of the rectangle is represented by 2x. The perimeter is 34 inches. W
Strike441 [17]

Answer: 20x-6 = 34

Step-by-step explanation:

Given: The length of rectangle is represented by 8x - 3.

The width of the rectangle is represented by 2x.

The perimeter is 34 inches.

Perimeter of rectangle = 2 (length + width)

Perimeter of rectangle = 2 (8x-3+2x)

Perimeter of rectangle = 2 (10x-3)

Perimeter of rectangle = 20x-6

Thus , the required equation that represent the perimeter: 20x-6 = 34
